Application example
The present application example is described based on the structure in the above embodiment, and is intended to clarify the operation mechanism of the present invention.
The working mechanism of the valve body when power is lost:
when the coil 121 is de-energized, the electromagnetic force disappears, the movable iron core 123 falls down along the static iron core sleeve 1221 under the action of the first compression spring 1232, and the air nozzle plug 1231 on the movable iron core 123 plugs the pilot air nozzle 1321, so that the gas in the pilot air cavity 132 cannot enter the diversion cavity 131; at this time, the gas in the direct acting valve outlet cavity 133 flows to the first through hole 1222 of the stationary core 122 through the exhaust groove 1233 and the second air hole 1234 on the movable core 123, and is finally discharged through the first air hole 12231 of the fixing nut 1223.
Because the gas input is lost, the air pressure in the actuating chamber 31 of the actuator 3 is reduced, the second compression spring 321 in the spring chamber 32 pushes the actuator piston 33 again, the gas in the actuating chamber 31 enters the piston chamber 22 through the first interface 24, and the shuttle piston 221 is pushed to block the communication between the piston chamber 22 and the shuttle valve inlet chamber 21.
Because the communication between the piston chamber 22 and the shuttle valve inlet chamber 21 is blocked, most of the gas in the piston chamber 22 and the shuttle valve outlet chamber 23 returns to the spring chamber 32 through the second port 25, further assisting the second compression spring 321 to push the actuator piston 33 to return, and a small part of the gas is exhausted through the exhaust nozzle 231. This completes the quick closing operation of the actuator 3.
The working mechanism of the valve body when electrified is as follows:
when the coil 121 is energized, the coil 121 generates a magnetic field around the moving iron core 122, the moving iron core 123 and the static iron core 122 attract each other under the action of the magnetic field force, the moving iron core 123 overcomes the acting force of the first compression spring 1232 to open the pilot air nozzle 1321, and at the moment, the pilot air can enter the direct-acting valve air outlet cavity 133 through the pilot air cavity 132 and the guide cavity 131.
When gas enters the shuttle valve inlet cavity 21 from the direct valve outlet cavity 133, the shuttle valve piston 221 is pushed to move, and the communication between the piston cavity 22 and the shuttle valve outlet cavity 23 is blocked.
Because the communication between the piston cavity 22 and the shuttle valve outlet cavity 23 is blocked, the gas enters the execution cavity 31 of the actuator 3 through the notch on the shuttle piston 221 and the first interface 24, the actuator piston 33 is pushed to overcome the second compression spring 321 to move, and then the rotating gear rotating shaft 311 is rotated to complete the opening operation of the actuator 3.
