How pneumatic actuator works?
When the compressed air enters the pneumatic actuator from the A nozzle, the gas pushes the double piston to move linearly to both ends (cylinder end), and the rack on the piston drives the rotating shaft to lie the counterclockwise rotation of the gear 90C, the electric valve It is opened. At this time, the gas at both ends of the pneumatic actuator valve is discharged with the B nozzle. Conversely, when the compressed air enters the pneumatic button from the B-guest to the ends of the surplus machine, the gas will push the double plug to move linearly in the middle. The rack on the piston drives the rotating shaft to lie. The gear can rotate 90C clockwise. The valve will be closed. At this point, the gas in the middle of the pneumatic actuator is discharged with the A nozzle. The above is the standard transmission principle. According to the user's needs, the pneumatic actuator can be installed in the opposite direction to the standard type, that is, the timing axis is rotated clockwise to open the valve, and the counterclockwise rotation is to close the valve. Single-acting (spring-return type) pneumatic actuator A nozzle is the air inlet, and B nozzle is the air outlet (B nozzle should be installed with silencer). The intake of the A nozzle is to open the valve, and the valve is closed by the spring force when the gas is cut off.
