As shown in fig. 1 to 6, an outlet valve provided by an embodiment of the present invention includes a valve body 1, a solenoid valve 2 mounted on the valve body 1, and a manual operation member 3 mounted on the valve body 1.

The valve body 1 comprises a water inlet cavity 11, a water outlet cavity 12, a water storage cavity 13, a first water way 14, a second water way 15 and a drainage water way 16.

A water-stop diaphragm 4 for controlling the on-off of the water outlet cavity 11 and the water inlet cavity 12 is arranged between the water outlet cavity 11 and the water inlet cavity 12.

The water-stop membrane 4 is at least partially positioned in the water storage cavity 13, and the water-stop membrane 4 seals and separates the water outlet cavity 12 from the water storage cavity 13.

The water-stop membrane 4 is provided with a water replenishing hole 40, and the water replenishing hole 40 is communicated with the water inlet cavity 11 and the water storage cavity 13.

The first water passage 14 and the drain water passage 16 communicate with each other through a first drain opening 141, and the second water passage 15 and the drain water passage 16 communicate with each other through a second drain opening 151.

A first plug 5 for controlling the opening and closing of the first water discharge opening 141 is further arranged in the first water path 14, and the first plug 5 is connected with the output end of the electromagnetic valve 2.

The second water passage 15 is further provided with a second stopper 6 for controlling opening and closing of the second drain opening 151, and the second stopper 6 is connected to the manual operation member 3.

According to the water outlet valve provided by the embodiment of the invention, the valve body 1 and the electromagnetic valve 2 are installed in the shell 100. A water inlet connector 200 and a water outlet connector 300 are also connected to the housing 100. When the water outlet valve is installed on a pipeline, the water inlet connector 200 is connected with a water pipe, and the water outlet connector 300 is connected with a water tap or water using equipment.

The water inlet cavity 11 in the valve body 1 is communicated with the water inlet connector 200, and the water outlet cavity 12 in the valve body 1 is communicated with the water outlet connector 300.

The water storage cavity 13 in the valve body 1 is separated from the water inlet cavity 11 and the water outlet cavity 12. The first waterway 14 and the second waterway 15 are respectively communicated with the water storage chamber 13. The first water passage 14 and the second water passage 15 communicate with the drain water passage 16 through the first drain opening 141 and the second drain opening 151, respectively. The water discharge channel 16 is communicated with the water outlet cavity 12.

The water-stop membrane 4 is assembled between the channels of the water inlet cavity 11 and the water outlet cavity 12 and used for controlling the on-off of the water paths of the water inlet cavity 11 and the water outlet cavity 12, so as to control the on-off of the water outlet valve. The water-stop membrane 13 seals and separates the water outlet cavity 12 and the water storage cavity 13. The water outlet cavity 12 and the water storage cavity 13 are not in water communication. The water-stop membrane 4 is provided with a water supplementing hole 40, the water storage cavity 13 is communicated with the water inlet cavity 11 through the water supplementing hole 40, and a water path is connected between the water storage cavity 13 and the water inlet cavity 11. The water replenishing holes 40 are generally small in diameter and are used for slowly replenishing water from the water inlet cavity 11 to the water storage cavity 13, and the water pressure change in the water storage cavity 13 is realized according to the quantity of the replenished water.

The water outlet of the water inlet cavity 11 faces the water storage cavity 13 or the water isolating membrane 4, so that the water pressure in the water inlet cavity 11 can act on the water isolating membrane 4, and the water isolating membrane 4 can be promoted to open the water paths of the water inlet cavity 11 and the water outlet cavity 12.

The diaphragm 4 is movable under the change of water pressure between the inlet chamber 11 and the reservoir chamber 13 to open or close the passage between the inlet chamber 11 and the outlet chamber 12.

When the water pressure in the water storage cavity 13 is substantially equal to the water pressure in the water inlet cavity 11 or a certain condition is met, the water-stop membrane 4 moves towards the channel between the water inlet cavity 11 and the water outlet cavity 12 to close the water channel between the water inlet cavity 11 and the water outlet cavity 12, and the water outlet valve is closed and cannot discharge water.

When the water pressure in the water storage cavity 13 is smaller than the water pressure in the water inlet cavity 11 or a certain condition is met, the water-stop diaphragm 4 moves towards the water storage cavity 13 to open the water path between the water inlet cavity 11 and the water outlet cavity 12, and the water outlet valve is opened to discharge water.

The first plug 5 is disposed on the first water passage 14 on the side close to the first drain opening 141. The first plug 5 can control opening and closing of the first drain opening 141.

The first plug 5 is connected with the output end of the electromagnetic valve 2. The second stopper 5 is movable in the first water passage 14 in a direction toward the first drain opening 141 by the electromagnetic valve 2 to block the first drain opening 141. Under the action of the electromagnetic valve 2, the first plug 5 can also move in the first waterway 14 in a direction away from the first drain opening 141 to open the first drain opening 141.

The second plug 6 is disposed on the second water passage 15 on the side close to the second drain opening 151, and the second plug 6 can control opening and closing of the second drain opening 151.

The second plug 6 is connected to the manually operable member 3. The manually operable member 3 may be a mechanical transmission member, such as a handle, a button, etc. The manual operating member 3 can push the second stopper 6 to move in the second waterway 15 toward the second drain opening 151, so as to close the second drain opening 151. The manual operating member 3 can pull the second stopper 6 to move in the second waterway 15 in a direction away from the second drain opening 151, so as to open the second drain opening 151.

The first plug 5 and the second plug 6 may be leather caps or rubber plugs.

When the water outlet valve is in the initial state, the water outlet valve is closed. At this time, the first plug 5 and the second plug 6 block the first drain opening 141 and the second drain opening 151, respectively. In this state, the water in the inlet chamber 11 enters the water storage chamber 13 through the water replenishing hole 40, and the water pressure in the water storage chamber 13 is increased to be substantially equal to the water pressure in the inlet chamber 11. The diaphragm 4 remains sealed in the passage between the inlet chamber 11 and the outlet chamber 12. At this time, the water path between the inlet chamber 11 and the outlet chamber 12 is cut off, and the outlet valve cannot discharge water.

When the water outlet valve needs to be opened, the first plug 5 can be moved by the electromagnetic valve 2 to open the first water outlet 141, the second plug 6 can be moved by the manual operation member 3 to open the second water outlet 151, and the first water outlet 141 and the second water outlet 151 can be simultaneously opened. After the first drainage port 141 and/or the second drainage port 151 are opened, the water in the water storage cavity 13 enters the drainage waterway 16 through the first waterway 14 and/or the second waterway 15, and is then rapidly discharged to the water outlet cavity 12 through the drainage waterway 16. At this time, the water pressure in the water storage cavity 13 is instantly reduced, and under the action of the water pressure in the water inlet cavity 11, the water-stop diaphragm 4 moves towards the water storage cavity 13, so that a channel between the water inlet cavity 11 and the water outlet cavity 12 is opened, a water path between the water inlet cavity 11 and the water outlet cavity 12 is conducted, water in the water inlet cavity 11 enters the water outlet cavity 13, and the water outlet valve is opened to supply water.

Therefore, the water outlet valve provided by the invention can realize electromagnetic valve control and manual control. The second plug 6 is kept to block the second drain opening 151, and the electromagnetic valve can be independently adopted for control, so that the automatic control switch of the water outlet valve is convenient. The first plug 5 is kept to block the first drain opening 141, manual control can be independently adopted, and the water outlet valve does not need to be connected electrically. When the electromagnetic valve 2 is in failure or has no electricity, manual control can be adopted, and the water outlet valve can be continuously used.

The water outlet valve provided by the invention does not need to open the water isolating diaphragm 4 by mechanical action in the whole process, does not need to arrange two water paths between the water inlet cavity 11 and the water outlet cavity 12 to realize the switching function, and has the advantages of simple structure, convenience in control and convenience in use by a user.

In one embodiment, as shown in fig. 3 and 6, the valve body 1 has an annular spacer 17 therein.

The water inlet 171 of the annular partition rib 17 faces the water storage cavity 13, and the water inlet 171 is communicated with the water inlet cavity 11.

The water outlet 172 of the annular partition rib 17 is communicated with the water outlet cavity 12.

The water-stop membrane 4 is disposed on the water inlet 171 of the annular rib 17.

The annular spacer 17 is integrally arranged in the valve body 1 and is a passage for communicating the water inlet cavity 11 with the water outlet cavity 12. The annular spacer 17 consists of a ring of ribs, thereby forming a cylindrical passage.

The water inlet 171 of the annular partition rib 17 faces the water storage cavity 13, and the water inlet 171 is communicated with the water inlet cavity 11 through a water flow channel. The outlet 172 of the annular rib 17 remains in communication with the outlet chamber 12.

The water-stop membrane 4 is disposed on the water inlet 171.

When the water-stop membrane 4 is sealed on the water inlet 171, the water inlet 171 is closed, the water path between the water inlet cavity 11 and the water outlet cavity 12 is cut off, the water outlet valve is closed, and water cannot flow out.

When the water-stop membrane 4 leaves the water inlet 171 under the action of water pressure, the water inlet 171 is opened, the water path between the water inlet cavity 11 and the water outlet cavity 12 is communicated, and the water outlet valve is opened to allow water to flow out.

Through set up water-stop membrane 4 on annular separates muscle 17, conveniently assemble water-stop membrane 4, also make things convenient for water-stop membrane 4 to seal and open water inlet 171.

The water-stop membrane 4, regardless of its movement, has its peripheral edge sealing the reservoir chamber 13.

In one embodiment, as shown in fig. 6, a first elastic member 7 for driving the water-stop membrane 4 to move toward the water inlet 171 is further provided in the water storage chamber 13.

The first elastic member 7 may be a spring, a plug spring, a disc spring, an elastic sheet, or the like.

The first elastic member 7 helps the diaphragm 4 to be restored to seal the water inlet 171. Because the acting forces of the water pressure of the first elastic member 7 and the water inlet cavity 11 on the water-stop diaphragm 4 are opposite, when the water-stop diaphragm 4 leaves the water inlet 171, the first elastic member 7 exerts the reacting force, so that the opening degree of the water-stop diaphragm 4 can be controlled, and the water outlet quantity of the water outlet valve can be further controlled.

The first elastic element 7 with different types can be selected according to requirements to control the water outlet quantity of the water outlet valve. If the elastic force of the first elastic piece 7 is large, the opening degree of the water-stop membrane 4 is small under the action of the same water pressure, and the water yield of the water outlet valve is small; if the elastic force of the first elastic element 7 is small, the opening degree of the water-stop membrane 4 is large under the same water pressure, and the water output of the water outlet valve is large. In one embodiment, as shown in fig. 6, the water-stop membrane 4 includes a support body 41 and a rubber seal 42 disposed on the support body 41.

The rubber packing 42 is disposed on the annular bead 17, and the first elastic member 7 is in contact with the support body 41.

The water supply hole 40 penetrates the rubber packing 42 and the support 41.

One end of the first elastic element 7 is fixed on the wall of the reservoir chamber 13 and the other end is connected or in contact with the support body 41.

The supporting body 41 is used for bearing the acting force of the first elastic member 7, and the first elastic member 7 is prevented from directly acting on the rubber sealing gasket 42, so that the service life of the rubber sealing gasket 42 is prevented from being affected.

The peripheral edge of the rubber packing 42 remains sealed from the water storage chamber 13 and the main body portion of the rubber packing 42 may cover the water inlet 171 or be spaced from the water inlet 171.

When the sum of the water pressure in the water storage cavity 13 and the acting force of the first elastic element 7 is basically equal to the water pressure in the water inlet cavity 11 or meets a certain condition, the supporting body 41 drives the rubber sealing gasket 42 to cover the water inlet 171, and the water path between the water inlet cavity 11 and the water outlet cavity 12 is closed.

When the first drain opening 141 and/or the second drain opening 151 are opened, so that the sum of the water pressure in the water storage cavity 13 and the acting force of the first elastic member 7 is smaller than the water pressure in the water inlet cavity 11, the water pressure in the water inlet cavity 11 can overcome the acting force of the first elastic member 7, so that the supporting body 41 drives the rubber sealing gasket 42 to move towards the water storage cavity 13, the water inlet 171 is opened, and the water path between the water inlet cavity 11 and the water outlet cavity 12 is opened.

In one embodiment, as shown in fig. 2, 4 and 5, the first waterway 14 has a first chamber 142 at an end thereof adjacent to the first drainage opening 141, and the first plug 5 is slidably disposed in the first chamber 142.

The output of the solenoid valve 2 is inserted in the first chamber 142. The output end of the solenoid valve 2 is sealed with the wall of the first chamber 142 by a sealing ring, so that water leakage can be avoided.

Preferably, as shown in fig. 5, the second waterway 15 communicates with the first chamber 142. The second waterway 15 is communicated with the water storage cavity 13 through the first waterway 14, so that the path of the second waterway 15 can be shortened, and the arrangement is convenient.

According to the needs, can set up the casing limiting plate on casing 100, set up the draw-in groove on handle 31, pull out the back in the position with handle 31, twist grip 31 for the draw-in groove and casing limiting plate joint are spacing with handle 31, and the outlet valve can go out water always.

After the water is discharged, the handle 31 can be pushed inward, the mandrel 33 moves toward the second water discharge opening 151, and the second plug 6 is driven to block the second water discharge opening 151. In the process, the second elastic member 34 also helps the second plug 6 to reset and helps the second plug 6 to keep blocking the second drainage opening 151.

In one embodiment, as shown in FIG. 7, the handle 31 is rotatably connected to the connecting sleeve 32. The handle 31 has a threaded portion 36 thereon, the threaded portion 36 engaging a threaded portion in the connecting sleeve 32. The friction between the threaded portion 36 on the handle 31 and the threaded portion in the connecting sleeve 32 is low. The second elastic member 34 is a torsion spring that can be stretched.

By rotating the handle 31, the handle 31 can move relative to the connecting sleeve 32, and further the core shaft 33 and the second plug 6 are driven to move outwards, the second plug 6 leaves the second water outlet 151, and the water outlet valve discharges water. In this process, the second elastic member 34 is compressed.

Because the handle 31 is connected with the connecting sleeve 32 through threads, after the handle 31 is rotated to open the second plug 6, the handle 31 can be kept at the open position and cannot be automatically retracted, and the water outlet valve keeps water outlet.

After the water is discharged, the handle 31 is rotated reversely until the second plug 6 blocks the second water discharge opening 151. In the process, the second elastic member 34 also helps the second plug 6 to reset and helps the second plug 6 to keep blocking the second drainage opening 151.

Generally, half or more turns of the handle 31 can drive the core shaft 33 to pull the second plug 6 away from the second outlet 151.

In one embodiment, the handle 31 is slidably connected to the connection sleeve 32. The handle 31 may be slidably connected to the connecting sleeve 32 by a linear guide. The handle 31 is in a push-pull type, and when the handle 31 is pulled outwards, the handle 31 directly pulls the core shaft 33 and the second plug 6 to move outwards. When the handle 31 is pushed inward, the handle 31 directly pushes the core shaft 33 and the second plug 6 to move inward. The second elastic element 34 can also drive the core shaft 33 and the second plug 6 to reset. In one embodiment, as shown in fig. 8, a baffle 35 is further disposed on a side of the second plug 6 facing the mandrel 33. The mandrel 33 passes through a baffle 35.

The side of the second plug 6 facing the baffle 35 is provided with at least one elastic projection 61.

A baffle 35 may be mounted in the second chamber 152 for defining the distance of the second plug 6 from the second drain opening 151. The elastic protrusion 61 plays a role of buffering, and prevents the second plug 6 from directly touching the baffle 35.

One end of the second elastic member 34 is connected to the connecting sleeve 32, the other end of the second elastic member is connected to the baffle 35, and the baffle 35 provides a stress mounting point for the second plug 6, so that the second elastic member 34 is prevented from damaging the second plug 6.

In conclusion, the water outlet valve provided by the invention can realize solenoid valve control and manual control, does not need to open the water-stop diaphragm by mechanical action in the whole process, does not need to arrange two paths of water paths between the water inlet cavity and the water outlet cavity to realize the switching function, and has the advantages of simple structure, convenience in control and convenience in use by a user.

According to the needs, the above technical schemes can be combined to achieve the best technical effect.

The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, several other modifications can be made on the basis of the principle of the present invention, and the protection scope of the present invention should be regarded.
