The pneumatic actuator is automatically opened after losing an external air source and is controlled to be opened or closed by the electromagnetic valve

Before use, the pressure range of the pressure switch indicator 12 is set according to design requirements, and an alarm signal is output after the pressure is lower than the set pressure. When the pressure of the natural gas in the gas source pipeline 13 is normal, the stop valve 8 is in a closed state, one path of the gas enters the gas storage tank 9 through the first one-way valve 11 to inflate the gas storage tank 9, the other path of the gas passes through the second one-way valve 14 to reach the electromagnetic valve 16, and under the control of the 4G network control module, the electromagnetic valve 16 finishes the gas entering the pneumatic actuator 1 or discharging the gas out of the pneumatic actuator 1. When the air source pipeline 13 loses pressure, the pressure switch indicator 12 gives an alarm, and meanwhile, the pneumatic actuator 1 cannot be driven to normally operate any more due to the reduction of the natural gas pressure.
