Background

In the development of the current industrial automation, the pneumatic vacuum technology is widely applied to various production lines, as shown in fig. 10, a vacuum generator 90 of the prior art has a pneumatic source 91, an exhaust port 92, and a suction port 93, and has a relatively simple internal structure;

the working principle of the vacuum generator 90 in the prior art is that compressed air is input from the air pressure source 91, then the compressed air is exhausted through the exhaust port 92, and the suction port 93 generates a vacuum adsorption effect by utilizing a suction effect, so that the purpose of adsorbing a workpiece is achieved; if no compressed air is maintained, the vacuum at the suction port 93 will dissipate directly into the atmosphere and the workpiece will also drop directly.

Accordingly, in view of the above-mentioned shortcomings of the conventional vacuum generator 90, the present inventors have devised an energy-saving vacuum control valve by integrating design features of maintaining vacuum suction and reducing compressed air consumption through elaborate planning and design to improve the problems of the prior art structure.

Detailed Description

The following best mode for carrying out the invention will be understood in accordance with the accompanying drawings and detailed description;

first, referring to fig. 1 to 2, the present invention discloses an energy-saving vacuum control valve, which comprises: a main body 10, which is composed of a control module 20, a vacuum control module 30, a vacuum generating module 40, a digital display module 50, and a vacuum filtering module 60 connected in sequence;

the control module 20 has an input port 201 for inputting a pneumatic source 80, a vacuum generating solenoid valve 21, a vacuum generating two-port two-position valve 22, a vacuum breaking solenoid valve 23, and a vacuum breaking adjusting button 24; the vacuum control module 30 has a vacuum adjusting knob 31 and an orifice 32, the vacuum generating module 40 has a vacuum generator 41, and the vacuum filtering module 60 has a suction port 601;

as shown in fig. 3, a first flow passage 70 is disposed at a position where the input port 201 communicates with the throttle hole 32; a second flow channel 71 is disposed between the throttle hole 32 and the vacuum generator 41 and the vacuum adjustment knob 31, and a pneumatic two-port two-position valve 33 is further disposed in the second flow channel 71; a third flow passage 72 is provided at a position where the orifice 32 and the vacuum generator 41 communicate with the suction port 601, and a check valve 42 is provided between the vacuum generator 41 and the suction port 601.

Referring to fig. 4-5, the air pressure source 80 inputted from the input port 201 is a positive pressure 81, and the flow rate of the positive pressure 81 inputted from the input port 201 is controlled by the vacuum generating solenoid valve 21 in the first flow channel 70 linking with the two-port two-position vacuum generating valve 22 to the orifice 32; the second flow channel 71 flows the positive pressure 81 to the vacuum adjusting button 31 and the vacuum generator 41, an atmospheric channel port 711 is further provided beside the vacuum adjusting button 31 to assist in discharging the inputted air pressure source 80, and an air-controlled two-port two-position valve 33 is further provided between the orifice 32 and the vacuum generator 41, the air-controlled two-port two-position valve 33 can be used to control the flow of the positive pressure 81 flowing to the vacuum generator 41, so that the flow of the positive pressure 81 at the discharge port 401 can be correspondingly controlled, and a muffler 411 is provided in the vacuum generator 41, and the muffler 411 can reduce the volume generated by the positive pressure 81 passing through the discharge port 401.

A check valve 42 is further disposed in the third flow channel 72 formed by the vacuum adjusting knob 31 and the vacuum generator 41 to the suction port 601, and the check valve 42 is opened at this time, so that the negative pressure 82 is filled in the third flow channel 72 to the suction port 601, and the suction port 601 is in a vacuum generating state and can be used for an adsorption object.

Referring to fig. 6 to 7, when the vacuum sensing switch 51 in the digital display module 50 senses that the negative pressure 82 in the third flow channel 72 is fully loaded, a vacuum signal 511 is generated, the vacuum signal 511 can cooperate with external wire connection for related linkage, the vacuum adjusting button 31 is opened upwards, and the positive pressure 81 of the second flow channel 71 is limited by the pneumatic control type two-port two-position valve 33 and the check valve 42 to flow into the third flow channel 72, so that the negative pressure 82 in the suction port 601 from the third flow channel 72 can form a vacuum holding state; if the vacuum generation solenoid valve 21 is still continuously activated when the negative pressure 82 in the third flow channel 72 is gradually dissipated after being continuously maintained for a long time, the vacuum can be immediately transferred from the first flow channel 70 to the third flow channel 72 through the second flow channel 71, so that the vacuum maintaining state can be continuously maintained, and the waste of the air pressure source 80 caused by the infinite discharge can be avoided, thereby achieving the purpose of saving energy.

Referring to fig. 8 to 9, in the vacuum maintaining state, if the vacuum breaking is required, after the vacuum generating solenoid valve 21 is closed, a fourth flow channel 73 is further disposed at the position of the vacuum breaking adjusting button 24, and the fourth flow channel 73 is communicated to the third flow channel 72, so that the positive pressure 81 introduced by the vacuum breaking solenoid valve 23 can push the check valve 42 to open through the fourth flow channel 73 via the third flow channel 72 to break the vacuum state of the suction port 601.

In summary, in the energy-saving vacuum control valve provided in the embodiment of the present invention, through the plurality of flow passages 70, 71, 72, 73 in the main body 10, the spring force of the vacuum adjusting button 31 is linked with the pressure in the main body 10, and the opening and closing of the pneumatic two-port two-position valve 33 and the check valve 42 are linked, so that the positive pressure 81 and the negative pressure 82 of the air pressure source 91 can be matched with the required supply amount corresponding to different vacuum states, the time for generating the vacuum state can be reduced, and the consumption of the air pressure source 80 can be reduced, thereby achieving the energy-saving effect.
