Example Embodiment
[0022] Example one:
[0023] See figure 1 , The pneumatic double-acting control valve of the present invention realizes the FC hand automatic control system, including valve 1, pneumatic double-acting actuator 2, first air control valve 3, second air control valve 4, solenoid valve 5, pressure switch 6 (for Adjustable pressure switch), on-site manual control panel 7, air filter and pressure reducing assembly 8, one-way valve 9, air tank 10, third air control valve 11, fourth air control valve 12, and fifth air control valve 13. The valve 1 and the pneumatic double-acting actuator 2 constitute a pneumatic control valve, the first air control valve 3, the second air control valve 4, the solenoid valve 5, the pressure switch 6, the on-site manual control panel 7, the air filter and pressure reduction The assembly 8, the one-way valve 9, the gas storage tank 10, the third gas control valve 11, the fourth gas control valve 12, the fifth gas control valve 13, and a number of gas pipeli...
Example Embodiment
[0025] Embodiment two:
[0026] See figure 2 , The pneumatic double-acting control valve of the present invention realizes the FO hand automatic control system, including valve 1, pneumatic double-acting actuator 2, first air control valve 3, second air control valve 4, solenoid valve 5, pressure switch 6 Adjustable pressure switch), on-site manual control panel 7, air filter and pressure reducing assembly 8, one-way valve 9, air tank 10, third air control valve 11, fourth air control valve 12, and fifth air control valve 13. Its connection method is the same as figure 1 Similar, the difference is that the normally closed port P of the second air control valve 4 is branched to the three-way ferrule joint between the fourth air control valve 12 and the third air control valve 11, and the normally open port of the second air control valve 4 Port R is equipped with a silencer and communicates with the atmosphere. The normally open port R of the fourth air control valve 12 is conne...
