Technical Field

Background

In order to spray fire extinguishing agent to extinguish fire, the pressure storage type fire extinguishing equipment needs to fill a certain amount of gas with pressure into the container, and the pressure of the gas is generally 1.2MPa to 20 MPa. The whole fire extinguishing equipment consists of a fire extinguishing agent storage container, a container valve, a pressure gauge, a fire extinguishing agent injection port, a signal feedback device and other parts, and the pressure storage type fire extinguishing equipment is stored under pressure for a long time, so that the connection part of the parts becomes a pressure leakage point.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Example one

As shown in fig. 1, one embodiment of the present invention provides a starting apparatus 100. The starting apparatus 100 includes: a shell 1, a gas production device 2 and an initiation device 3.

Specifically, the casing 1 is provided with at least one spout 1513, and the inside of the casing 1 is provided with a sealed chamber 1113. As shown in fig. 2, the gas generating apparatus 2 includes an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21. The hermetic container 21 is connected to the housing 1. The initiation device 3 is positioned outside the gas production device 2. The initiator assembly 3 includes a striker 31 and an initiator 32. The striker 31 is provided in correspondence with the sealed container 21 for piercing the sealed container 21 to cause the driving medium 22 to be ejected out of the sealed container 21 and form gas. One end of the initiator 32 is located within the sealed chamber 1113 and the other end of the initiator 32 extends through the housing 1 to the outside of the housing 1, the initiator 32 being used to raise the pressure in the sealed chamber 1113. The sealing chamber 1113 is disposed corresponding to the striker 31, and is configured to directly or indirectly drive the striker 31 to move toward the sealed container 21 by using the elevated air pressure, so that the striker 31 punctures the sealed container 21.

According to the starting device 100 provided by the embodiment of the invention, the driving medium 22 is packaged in the integrated sealed container 21, and when fire is needed to be extinguished, the sealed container 21 can be opened through the initiation device 3, so that the driving medium 22 is sprayed out of the sealed container 21 and gas capable of driving the extinguishing agent 220 to be sprayed out is formed, the gas can enter the extinguishing agent storage container 210 to quickly pressurize the extinguishing agent storage container 210, and further the extinguishing agent 220 is sprayed out under the action of pressure to extinguish the fire. Thus, the fire extinguishing agent 220 does not need to be stored under pressure, thereby fundamentally solving the pressure leakage problem of the existing pressure storage type fire extinguishing apparatus, not only saving the maintenance cost of periodical pressurization, but also improving the use reliability of the fire extinguishing apparatus 200.

Specifically, the starting device 100 comprises a housing 1, a gas generating device 2 and an initiating device 3. The housing 1 is provided with at least one spout 1513, and the spout 1513 is provided to be capable of communicating with the fire extinguishing agent storage container 210 so that the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 can be sprayed out through at least the spout 1513 of the actuating device 100. The number of the nozzles 1513 may be one or more, and the plurality of the nozzles 1513 is advantageous for improving the fire extinguishing efficiency.

As shown in fig. 2, the gas generating device 2 is a non-explosive device, and specifically includes a sealed container 21 and a driving medium 22. The sealed container 21 is of an integrated structure, and the driving medium 22 is stored in the sealed container 21. When a fire occurs and a fire is to be extinguished, the sealed container 21 can be opened through the initiation device 3, and the sealed container 21 is rapidly decompressed when being opened, so that the driving medium 22 is sprayed in a gas form, the air pressure in the fire extinguishing agent storage container 210 is rapidly increased, and the fire extinguishing agent 220 is driven to be sprayed for extinguishing the fire.

Therefore, the fire extinguishing agent 220 does not need to be stored under pressure and can be sprayed out only by quickly pressurizing through the gas generating device 2 when in use, thereby solving the problem that the fire extinguishing equipment 200 cannot normally spray the fire extinguishing agent 220 due to pressure leakage of the existing pressure storage type fire extinguishing equipment, saving the maintenance cost of periodical pressurization and simultaneously saving a pressure gauge.

The sealed container 21 of the gas generating device 2 is of an integrated structure, is a sealed whole and is a complete part, and has no structures such as a sealing ring, a sealing glue, a sealing cover, a sealing bolt and the like, and can be independently stored, as shown in fig. 2, so that the problem of pressure leakage does not exist, and the driving medium 22 can be stably sealed in the sealed container 21 and cannot be leaked. The shape of the sealed container 21 is not limited, and for example, the cross section of the sealed container 21 may be circular, oval, rectangular, square, triangular, or the like. The sealed container 21 may be a metal container.

The gas generator 2 may spray more or less gas for a longer or shorter time, and may be selected according to the amount of the driving medium 22.

In addition, the prior non-pressure storage type fire extinguishing equipment is characterized in that the initiation device 3 is arranged in the gas generating device 2, and the gas is initiated to be sprayed out from the gas generating device 2 by adopting an electric initiation or thermal initiation mode, because the gas generating device 2 adopted by the prior non-pressure storage type fire extinguishing equipment is an initiating explosive, when the initiation device 3 initiates the gas generating device 2, the high temperature of hundreds of degrees centigrade is instantly generated. The gas can explode when meeting high temperature, so the gas extinguishing device can not be used, and the gas extinguishing device can only be suitable for dry powder extinguishing devices. The starting device 100 provided by the scheme arranges the initiation device 3 outside the gas production device 2, and initiates the gas production of the gas production device 2 in a manner of releasing pressure of the sealed container 21 by opening the sealed container 21, so that the starting device is not only suitable for dry powder fire extinguishing devices, but also suitable for gas fire extinguishing devices and liquid fire extinguishing devices, thereby greatly expanding the range of non-pressure storage type fire extinguishing equipment and solving the problem of pressure release for years in the field of pressure storage type fire extinguishing equipment.

In addition, compare in current non-pressure storage formula dry powder fire extinguishing apparatus, starting drive 100 of this scheme of adoption can avoid the ignition to cause the improper condition that leads to the dry powder explosion to take place to the potential safety hazard that the explosion of fire extinguishing apparatus 200 self and cause has been avoided. Compared with the existing pressure storage type gas fire extinguishing equipment, the starting device 100 of the scheme can change the pressure storage type gas fire extinguishing equipment into non-pressure storage type gas fire extinguishing equipment, fundamentally solves the pressure leakage problem of the gas fire extinguishing equipment, and improves the fire extinguishing reliability of the gas fire extinguishing equipment.

Certainly, the starting device provided by the embodiment of the invention not only can be used for fire extinguishing equipment, but also can be widely applied to pressurized equipment (with pressurized containers) in various fields of national economy such as energy, traffic, metallurgy, electric power, communication and the like, and the conventional pressurized equipment can be converted into non-pressure storage equipment, so that the problem of pressure relief bothering the industry for many years is solved, and effective guarantee is provided for protecting national property and the safety of people.

When the starting device 100 is used in other equipment, correspondingly, the spout 1513 is used for ejecting the substance in the container of other equipment, and the driving medium 22 in the gas generating device 2 ejects the sealed container 21 and forms a gas for driving the ejection of the substance in the container of other equipment.

As shown in FIG. 1, the initiator assembly 3 includes a striker 31 and an initiator 32. The initiator 32 is used to drive the movement of the striker 31. The striker 31 can rapidly pierce the sealed container 21 with the tip portion without generating sparks, and is safe in use and high in opening efficiency.

Further, as shown in FIG. 1, a sealed chamber 1113 is provided in the housing 1, and one end of the initiator 32 is located in the sealed chamber 1113. When the end of the initiator 32 located outside the sealed chamber 1113 is triggered, the initiator 32 can initiate the air pressure in the sealed chamber 1113 to rise, and the rising air pressure in the sealed chamber 1113 can directly or indirectly act on the striker 31, so as to directly or indirectly drive the striker 31 to move, and the striker 31 punctures the sealed container 21. Therefore, the gas generation device 2 is prevented from generating gas by the manner that the initiator 32 is directly inserted into the sealed container 21 and the driving medium 22 is initiated to burn or explode, and accordingly, the initiating explosive device is prevented from being used as the gas generation device 2.

Of course, the inducing means 3 is not limited to the above-described ones. For example, the initiating device can also comprise a cutter and a motor, wherein the motor drives the cutter to move, so that the cutter cuts the sealed container and the sealed container is opened; alternatively, the initiating device may comprise a small power drill by which the sealed container is opened.

In an exemplary embodiment, as shown in FIG. 1, a piston 16 is disposed within the housing 1. The piston 16 is in sliding fit with the housing 1 and encloses a sealed chamber 1113 with the housing 1. The striker 31 is fixedly connected to the piston 16. The initiator 32 is used to raise the air pressure in the sealed chamber 1113 to drive the piston 16 to move the striker 31 in a direction approaching the sealed container 21.

In this embodiment, the initiator 32 is specifically configured to raise the pressure in the chamber 1113, and to use the raised pressure to drive the piston 16. Since the piston 16 is fixedly connected to the striker 31, the piston 16 can bring the striker 31 into synchronous motion. This corresponds to indirectly moving the striker 31 in the direction approaching the hermetic container 21 by the air pressure raised in the hermetic chamber 1113.

Of course, when the striker 31 and the housing 1 enclose the sealed chamber 1113, the striker 31 can be directly driven to move toward the sealed container 21 by the air pressure of the sealed chamber 1113.

The plunger 16 is used to drive the striker 31 to move, which is beneficial to simplify the structure of the striker 31 and improve the sealing performance of the sealing chamber 1113 compared with the method of directly driving the striker 31 to move.

At least one sealing ring can be sleeved between the piston 16 and the housing 1 to further improve the sealing performance of the sealing cavity 1113. Further, a sealing groove for installing a sealing ring may be correspondingly provided on the outer side wall of the piston 16.

The striker 31 and the piston 16 may be fixedly connected by interference fit, plastic-coated molding, or the like.

In one exemplary embodiment, the initiator 32 comprises an electrical initiator. As shown in fig. 1, the electrical initiator includes a resistor 321 and a connecting wire 322 connected to the resistor 321, the resistor 321 is located in the sealed chamber 1113, and the connecting wire 322 extends through the housing 1 to the outside of the housing 1.

In another exemplary embodiment (not shown), the initiator 32 comprises a thermal initiator.

In yet another exemplary embodiment (not shown), the initiator 32 includes both the electrical initiator described above and the thermal initiator described above.

The initiator 32 may be an electric initiator, and by connecting a power supply, the resistor 321 heats up to increase the air pressure in the sealed chamber 1113, thereby causing the striker 31 to move to open the sealed container 21. The electric initiator has three indexes of starting current, safe current and a resistance 321 value. These three indices satisfy the following relationships: the safe current is smaller than the starting current, and the resistor 321 is not heated when being electrified for five minutes in the safe current index; when the current reaches or exceeds the starting current, the resistor 321 heats; the smaller the value of the resistor 321 is, the larger the current is, and conversely, the larger the value of the resistor 321 is, the smaller the current is; the safe current, the starting current and the value of the resistor 321 can be set according to requirements.

The initiator 32 may also be a thermal initiator, and the thermal initiator includes a thermosensitive element, which is sensitive to the external temperature, and when a fire occurs, the thermosensitive element can sense the rise of the external temperature to generate heat, so that the air pressure in the sealed chamber 1113 rises, and the striker 31 is automatically triggered to move to open the sealed container 21.

Of course, the initiator 32 may also include both an electrical initiator and a thermal initiator, so that the fire extinguishing apparatus can be started either manually or automatically, thereby effectively preventing the risk of the fire extinguishing apparatus being unable to be started.

In an exemplary embodiment, as shown in fig. 1, the housing 1 includes: a housing 11 and a sealing structure 12. Wherein the housing 11 is provided with a first mounting cavity 111. The striker 31 and the piston 16 are located in the first mounting cavity 111. The first mounting cavity 111 is open at one end. The seal structure 12 is connected to the housing 11 and seals the open end of the first mounting cavity 111. An initiator 32 is disposed through the seal structure 12. The space between the seal 12 and the piston 16 forms a seal chamber 1113.

Wherein, the housing 11 can be a metal housing 11, and the piston 16 can be a silicon rubber piston 16 or a rubber piston 16. Further, the striker 31 may be made of a metal member having a high hardness, and is convenient for quick puncturing of the sealed container 21.

In an exemplary embodiment, as shown in FIG. 1, the seal structure 12 includes: a first cover 121 and a sealing plug 122. Wherein, the first cover 121 is connected to the housing 11 and covers the open end of the first mounting cavity 111. The sealing plug 122 is at least partially positioned within the first mounting cavity 111 and abuts the first cover 121. The space between the sealing plug 122 and the piston 16 forms a sealed chamber 1113.

The sealing structure 12 comprises a first lid 121 and a sealing plug 122. The sealing plug 122 and the piston 16 define a sealing cavity 1113 in the housing 11, and the sealing plug 122 and the piston 16 can seal two ends of the sealing cavity 1113, thereby being beneficial to improving the sealing reliability of the sealing cavity 1113.

Wherein the mounting groove 1111 is used for mounting the first cover 121 and the sealing plug 122. The slide channel 1112 is communicated with the mounting groove 1111. The cross-sectional area of the sliding channel 1112 is smaller than the cross-sectional area of the mounting groove 1111 such that a support surface 1114 (shown in fig. 3) is formed between the sliding channel 1112 and the mounting groove 1111. The sealing plug 122 abuts the seating surface 1114. Piston 16 is positioned within slide channel 1112 and is in sliding engagement with slide channel 1112.

The mounting groove 1111 and the sliding channel 1112 have different cross-sectional areas, so that the first mounting cavity 111 has a stepped hole structure. And the inlet end of the stepped hole structure is relatively thick, so that the piston 16 and the striker 31 can be quickly and conveniently inserted into the sliding channel 1112, the assembly difficulty is reduced, and the assembly efficiency is improved.

On the other hand, the support surface 1114 of the stepped hole structure also has a limiting effect on the sealing plug 122, so that the sealing plug 122 can be prevented from moving into the sliding channel 1112, and the stability of the sealing plug 122 is further improved.

In addition, the stepped bore seating surface 1114 also provides a mounting location for the sealing plug 122. When the sealing plug 122 rests against the seating surface 1114, it is indicated that the sealing plug 122 is in place, which prevents the sealing plug 122 from being excessively compressed and affecting the useful life of the sealing plug 122.

In an exemplary embodiment, as shown in fig. 1, the first cap 121 is provided with a stopper groove 1211. A portion of the sealing plug 122 is retained within the retaining groove 1211. The initiator 32 is disposed through the sealing plug 122 and the first cap 121.

The sealing plug 122 is partially retained in the retaining groove 1211 of the first cover 121, which is advantageous for further improving the stability of the sealing plug 122. Moreover, the present solution facilitates assembling the first cover 121, the sealing plug 122 and the initiator 32 into a module, and then assembling the module with the housing 11, which is beneficial to reduce the assembling difficulty and improve the assembling efficiency.

Further, the first cover 121 may be a metal cover. The first cover 121 and the housing 11 can be connected by screw threads, so that the connection is reliable and the assembly is convenient.

In an exemplary embodiment, as shown in fig. 1, a mounting hole 131 and at least one air passage 132 are formed in the housing 1. The sealed container 21 includes a head portion 211 and a body portion 212, as shown in fig. 2. The head 211 is mounted in the mounting hole 131, and the head 211 is provided corresponding to the striker 31 for ejecting the gas formed by the driving medium 22. The gas passing passage 132 is communicated with the mounting hole 131, and one end of the gas passing passage 132 penetrates the housing 1 for delivering the gas formed by the driving medium 22 to the fire extinguishing agent storage container 210.

The housing 1 is provided with a mounting hole 131 and a gas passing passage 132. The mounting hole 131 is used to mount the head 211 of the hermetic container 21, and the body 212 of the hermetic container 21 can be inserted into the fire extinguishing agent storage container 210. The air passage 132 is used to supply air to the fire extinguishing agent storage container 210, so that the fire extinguishing agent storage container 210 is rapidly pressurized to spray the fire extinguishing agent 220. The gas passing channel 132 is communicated with the mounting hole 131 to ensure that gas sprayed out of the head part 211 of the sealed container 21 can enter the gas passing channel 132; one end of the air passing passage 132 penetrates the housing 1, so that the air passing passage 132 can communicate with the fire extinguishing agent storage container 210 after the housing 1 is assembled with the fire extinguishing agent storage container 210.

Of course, when the starting device is used in other equipment, the gas passing channel is used for conveying the gas formed by the driving medium to the container body of the other equipment.

In an exemplary embodiment, as shown in fig. 1, the housing 1 includes a shell 11 and a support base 13. A second mounting cavity 112 is provided in the housing 11. The support base 13 is mounted in the second mounting cavity 112. The mounting hole 131 and the air passage 132 are provided on the support base 13.

Furthermore, the supporting seat 13 is in threaded connection with the shell 11, so that the connection is reliable and the assembly is convenient. The head 211 of the sealed container 21 is in threaded connection with the supporting seat 13, so that the connection is reliable and the assembly is convenient.

Further, the number of the air passing channels 132 is plural, and the plural air passing channels 132 are arranged at intervals along the circumference of the support base 13, as shown in fig. 4, so that the gas can be rapidly and uniformly introduced into the fire extinguishing agent storage container 210.

In an exemplary embodiment, as shown in fig. 1, the starting apparatus 100 further comprises: the first sealing membrane 141. The first sealing diaphragm 141 is disposed in the second mounting cavity 112 and located between the striker 31 and the sealed container 21, and the first sealing diaphragm 141 abuts against one end of the support base 13 close to the striker 31.

When a fire occurs, the striker 31 pierces the first sealing membrane 141, thereby piercing the sealed container 21. The first sealing membrane 141 is provided to prevent the striker 31 from being triggered by mistake and the sealed container 21 from being punctured, thereby improving the safety of the starting device 100.

The first sealing diaphragm 141 may be an aluminum diaphragm or other materials.

In an exemplary embodiment, as shown in FIG. 1, the housing 1 is provided with at least one ejection channel 114, the ejection channel 114 communicating with the ejection port 1513. The activation device 100 further comprises a second sealing membrane 142. The second sealing membrane 142 is disposed corresponding to the ejection port 1513 for interrupting the communication between the ejection channel 114 and the ejection port 1513.

The ejection passage 114 is provided to be capable of communicating with the fire extinguishing agent storage container 210. The second sealing film 142 ensures that the spraying channel 114 is disconnected from the spraying port 1513 in a non-use state of the fire extinguishing apparatus 200, thereby preventing the fire extinguishing agent 220 from being sprayed out to cause property loss or personal injury. In case of fire, after the trigger device 3 opens the sealed container 21, the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 flows to the spraying channel 114 under the action of air pressure, and then breaks through the second sealing membrane 142, and is sprayed out through the spraying port 1513 to extinguish the fire. Of course, when the cartridge 100 is used in another apparatus when it is started, the ejection passage 114 is provided so as to be able to communicate with the container body of the other apparatus.

Compared with a scheme that a sealing valve is adopted to disconnect the nozzle 1513 from the ejection channel 114, and an elastic member is further utilized to improve the stability of the sealing valve, the structure of the scheme is simpler.

The second sealing diaphragm 142 may be an aluminum diaphragm or other diaphragms.

The siphon tube 4 can suck the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 into the spouting passage 114 by using the siphon principle, so that the fire extinguishing agent 220 continuously enters the spouting passage 114, thereby improving fire extinguishing efficiency. Furthermore, the siphon 4 is a plastic pipe, and the siphon 4 is in threaded connection with the shell 1.

Of course, for small fire extinguishing installations, the amount of extinguishing agent 220 is relatively small, and the siphon 4 can also be eliminated. Alternatively, in the case where the fire extinguishing agent storage container 210 is up and the starting device 100 is down, the fire extinguishing agent 220 may automatically flow toward the spouting passage 114 by gravity, and in this case, the siphon tube 4 may be eliminated.

In an exemplary embodiment, as shown in FIG. 1, the housing 1 includes an outer shell 11 and a spray structure 15.

Alternatively, the driving medium 22 may be a solid medium, which is enclosed in the sealed container 21 in a solid state and sublimated to be sprayed with gas after the sealed container 21 is opened, such as solid carbon dioxide (dry ice).

In other words, the driving medium 22 is a medium from solid to gas, and is directly decompressed into gas through the sealed container 21, rather than being burned or exploded to generate gas, so that the gas generating device 2 is still a non-explosive work.

In this embodiment, the initiator 32 ' is specifically configured to increase the air pressure in the sealed chamber 1111 ', so as to drive the movement of the striker 31 ' by the increased air pressure, and the concept is ingenious.

In one illustrative example, further, as shown in fig. 4, the striker 31' includes: a sliding portion 311 'and a needling portion 312'. The sliding portion 311 'and the housing 1' enclose a sealed cavity 1111 'and are in sliding fit with the housing 1'.

The housing 1 ' is provided therein with a mounting hole 131 ' and a gas passing passage 132 '. The mounting hole 131 'is used to mount the head portion 211' of the hermetic container 21 ', and the body portion 212' of the hermetic container 21 'can be inserted into the fire extinguishing agent storage container 210'. The air passage 132 'is used to supply air to the fire extinguishing agent storage container 210', and the fire extinguishing agent storage container 210 'is rapidly pressurized to spray the fire extinguishing agent 220'. The gas passing channel 132 ' is communicated with the mounting hole 131 ' to ensure that gas sprayed out of the head part 211 ' of the sealed container 21 ' can enter the gas passing channel 132 '; one end of the air passing channel 132 'penetrates the housing 1' to ensure that the air passing channel 132 'can communicate with the fire extinguishing agent storage container 210' after the housing 1 'is assembled with the fire extinguishing agent storage container 210'.

In one illustrative example, further, as shown in fig. 4, the housing 1 ' includes a shell 11 ' and a support base 13 '. A second mounting cavity 112 'is provided in the housing 11'. The support base 13 'is mounted in the second mounting cavity 112'. The mounting hole 131 ' and the air passage 132 ' are provided on the support base 13 '.

The shell 1 'is split into the shell 11', the supporting seat 13 'and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1' is facilitated, so that the structure of the starting device 100 'is optimized, and the assembly difficulty of the starting device 100' is reduced.

In an exemplary embodiment, the supporting base 13 'is further provided with a relief hole 133', and the relief hole 133 'is communicated with the mounting hole 131'. The needle-punched portion 312 'is inserted into the escape hole 133', as shown in fig. 4. The cross-sectional area of the escape hole 133 'is larger than that of the mounting hole 131'. The air passage 132 'penetrates through both ends of the support base 13' along the axial direction of the avoiding hole 133 ', and the air passage 132' penetrates through the hole wall of the avoiding hole 133 'along the radial direction of the avoiding hole 133'.

In this embodiment, the provision of the avoiding hole 133 ' reduces the distance between the striker 31 ' and the sealed container 21 ', so that the striker 31 ' can rapidly pierce the sealed container 21 '. Meanwhile, the avoiding hole 133 ' is relatively thick, and the mounting hole 131 ' is relatively thin, so that the air passage 132 ' can penetrate through the hole wall of the avoiding hole 133 ' along the radial direction of the avoiding hole 133 ', the hole wall of the avoiding hole 133 ' is not a complete annular structure in the circumferential direction, and the hole wall of the mounting hole 131 ' can be a complete annular structure in the circumferential direction. In this way, the mounting hole 131 'and the head 211' of the hermetic container 21 'can have a larger contact area to improve the fixing reliability of the hermetic container 21'; and the gas jetted from the head 211 'in the mounting hole 131' can more easily enter the gas passing channel 132 ', thereby increasing the initiation speed of the initiation device 3'.

Further, the cross-section of the avoiding hole 133' is circular. The mounting hole 131' has a circular cross-section. The avoiding hole 133 'is coaxially disposed with the mounting hole 131', and the radius of the avoiding hole 133 'is greater than that of the mounting hole 131'.

Further, the number of the air passing channels 132 'is plural, and the plural air passing channels 132' are spaced along the circumference of the support base 13 ', so that the air can be rapidly and uniformly introduced into the fire extinguishing agent storage container 210'.

In one illustrative example, further, as shown in FIG. 4, the cross-sectional area of second mounting cavity 112 'is greater than the cross-sectional area of first mounting cavity 111', such that first mounting cavity 111 'and second mounting cavity 112' form a stepped bore configuration. The end face of the support seat 13 ' close to the first mounting cavity 111 ' abuts against the end face of the second mounting cavity 112 '. The end surface of the supporting seat 13 ' close to the first mounting cavity 111 ' protrudes from the inner side surface of the first mounting cavity 111 ' to form a stopping surface 134 ' for stopping the striker 31 ', as shown in fig. 4.

During assembly, the sealing plug 12 ' may be first installed into the first installation cavity 111 ' through the second installation cavity 112 ', then the striker 31 ' is installed into the first installation cavity 111 ' through the second installation cavity 112 ', then the supporting seat 13 ' is installed into the second installation cavity 112 ' until the supporting seat 13 ' abuts against the step of the stepped hole, and then the head 211 ' of the sealed container 21 ' is installed into the installation hole 131 ' of the supporting seat 13 '. Thus, the assembly process of the starting apparatus 100' is simple and convenient.

In addition, when the striker 31 'moves to abut against the support seat 13' in the use process, the striker is stopped by the support seat 13 'and cannot move continuously, so that the sliding stroke of the striker 31' is limited, and the phenomenon that the sealed container 21 'is excessively deformed and falls off due to the overlarge movement amplitude of the striker 31' is avoided.

Further, the piercing portion 312 'of the striker 31' is provided with a transition passage 3121 'communicating with the air passage 132', as shown in fig. 4. Thus, the gas in the sealed container 21 'can also enter the gas passing channel 132' through the transition channel 3121 ', thereby further increasing the initiation speed of the initiation device 3'. In addition, this may further reduce the mass of the striker 31 'and further reduce the requirements for the initiator 32'.

In one illustrative example, further, as shown in fig. 4, the housing 1 'is provided with at least one ejection passage 116', and the ejection passage 116 'communicates with the ejection port 115'. The activation device 100 ' further comprises a sealing valve 4 ', the sealing valve 4 ' being adapted to disconnect the ejection channel 116 ' from the nozzle opening 115 ', the sealing valve 4 ' being arranged to conduct the ejection channel 116 ' to the nozzle opening 115 ' under the impact of a fluid, such as fire suppressant 220 '.

The spouting passage 116 'is provided to be capable of communicating with the fire extinguishing agent storage container 210'. The sealing valve 4 'ensures that the spraying channel 116' is disconnected from the spraying opening 115 'when the fire extinguishing apparatus is not in use, thereby preventing the fire extinguishing agent 220' from spraying out to cause property loss or personal injury. In case of fire, when the trigger device 3 'opens the sealed container 21', the fire extinguishing agent in the fire extinguishing agent storage container 210 'flows to the discharge passage 116' under the action of air pressure, and further, the sealed valve 4 'is opened, and the fire is discharged from the discharge opening 115'. Of course, when the starting device 100 'is used in other apparatuses, the ejection channel 116' is provided to be able to communicate with the container body of the other apparatuses.

Wherein, the sealing valve 4 'can adopt a metal sealing plug, and is in interference fit with the shell 1'.

Further, at least one sealing ring is sleeved between the sealing valve 4 ' and the housing 1 ' to further improve the sealing reliability of the sealing valve 4 '. The outer side wall of the sealing valve 4 'is provided with a sealing groove 3113' for mounting a sealing ring.

Further, the number of the ejection channels 116 'may be equal to and correspond to the number of the ejection ports 115', and the number of the sealing valves 4 'may be equal to and correspond to the number of the ejection channels 116', so as to ensure that each ejection channel 116 'and each ejection port 115' can be in a disconnected state in the absence of fire.

The number of the ejection channels 116 'may also be different from the number of the nozzles 115', for example, the ejection channels 116 'may have a three-way structure, a four-way structure, or the like, and one ejection channel 116' may communicate with three or four nozzles 115 ', which is beneficial to reducing the number of the sealing valves 4', thereby simplifying the product structure and reducing the product cost.

In one illustrative example, further, as shown in fig. 4, the starting apparatus 100' further includes: the siphon tube 5 ' is fixedly connected to the housing 1 ' and communicates with the spouting passage 116 '.

When the starting apparatus 100 'is completely assembled with the fire extinguishing agent layer storage container 210', the siphon tube 5 'is inserted into the fire extinguishing agent storage container 210'. The siphon tube 5 'can suck the fire extinguishing agent 220' in the fire extinguishing agent storage container 210 'into the spouting passage 116' by using the siphon principle, so that the fire extinguishing agent 220 'continuously enters the spouting passage 116', thereby improving the fire extinguishing efficiency. Furthermore, the siphon 5 ' is a plastic pipe, and the siphon 5 ' is in threaded connection with the shell 1 '.

Of course, for small fire-extinguishing systems, the amount of extinguishing agent 220 'is relatively small, and the siphon 5' can also be eliminated. Alternatively, in the case where the fire extinguishing agent storage container 210 ' is up and the starting device 100 ' is down, the fire extinguishing agent 220 ' may automatically flow toward the spouting passage 116 ' by gravity, and in this case, the siphon tube 5 ' may be eliminated.

In an exemplary embodiment, as shown in fig. 4, a third installation cavity 113 'and a bypass cavity 117' communicating with the third installation cavity 113 'are further provided in the housing 1'. The sealing valve 4 'is installed in the third installation chamber 113' to interrupt the communication between the spouting passage 116 'and the spouting port 115' and is provided to be movable into the escaping chamber 117 'under the impact of the fluid (e.g., the fire extinguishing agent 220') to communicate the spouting passage 116 'and the spouting port 115'.

Thus, the sealing valve 4 'is still located in the housing 1' after being impacted by the fire extinguishing agent 220 ', and the sealing valve 4' can be prevented from bursting out to cause property loss or cover on human body.

In one illustrative example, further, as shown in fig. 4, the starting apparatus 100' further includes: the elastic member 6 ' is disposed in the housing 1 ' and abuts against the sealing valve 4 ' for restricting the sealing valve 4 ' from moving to the avoiding chamber 117 '.

The elastic piece 6 'can exert an acting force on the sealing valve 4', so that the position stability of the sealing valve 4 'is improved, and the fire extinguishing agent 220' is prevented from being sprayed out by mistake in the absence of fire to cause property loss or personal injury.

Wherein, the elastic member 6' can be a compression spring, a spring plate, a silica gel ball and other structures.

In one illustrative example, further, as shown in fig. 4, the housing 1 ' includes a sealing cover 14 ' and a shell 11 '. The housing 11 'is provided with a fourth mounting cavity 114' opened at both ends. One end of the fourth mounting cavity 114 ' is communicated with the third mounting cavity 113 ', and the sealing cover 14 ' is used for covering one end of the fourth mounting cavity 114 ' far away from the third mounting cavity 113 '.

The shell 1 'is split into the shell 11', the sealing cover 14 'and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1' is facilitated, so that the structure of the starting device 100 'is optimized, and the assembly difficulty of the starting device 100' is reduced.

Specifically, in the assembling process, the sealing valve 4 'may be installed in the third installation cavity 113' through the fourth installation cavity 114 ', the elastic member 6' is then installed in the housing 11 ', the elastic member 6' abuts against the sealing valve 4 ', and then the sealing cover 14' is covered.

Further, as shown in fig. 4, the sealing cover 14 'is provided with a stopper groove 141', and a portion of the elastic member 6 'is stopped in the stopper groove 141'.

The limiting groove 141 'can limit the elastic piece 6' and prevent the elastic piece 6 'from inclining, shifting and the like, thereby improving the use reliability of the elastic piece 6'.

In an illustrative example, further, as shown in fig. 4, the end of the sealing valve 4 ' facing the sealing cover 14 ' is also provided with a stopper groove 42 '. One end of the elastic member 6 ' can be inserted into the limiting groove 42 ', which is beneficial to further preventing the elastic member 6 ' from tilting, shifting and the like, and ensuring good matching of the elastic member 6 ' and the sealing valve 4 '.

Further, as shown in fig. 4, the sealing valve 4 ' is further provided with a limiting boss 41 ' at an end thereof facing the sealing cover 14 '. The cross-sectional area of the limiting boss 41 ' is larger than that of the third mounting cavity 113 ', so that the sealing valve 4 ' can be prevented from being stuck in the third mounting cavity 113 ' to influence the normal ejection of the fire extinguishing agent 220 '.

The space between the piston 16 and the sealing plug 122 forms a sealed chamber 1113. The striker 31 is fixedly connected to the piston 16. The electrical initiator's resistor 321 is located within the sealed chamber 1113 and the connecting wire 322 extends out of the housing 11 through the sealing plug 122 and the first cap 121.

The support base 13 is mounted in the second mounting cavity 112 by means of a threaded connection. The head 211 of the sealed container 21 is screwed to the support base 13, and the body 212 of the sealed container 21 is inserted into the fire extinguishing agent storage container 210. The support base 13 is provided with a gas passing passage 132, and the gas passing passage 132 is communicated with the fire extinguishing agent storage container 210.
