Who knows the working principle of pneumatic control switch?

Pneumatic control system can be formed by connecting pressure control valve, flow control valve, direction control valve, logic element, sensing element and pneumatic accessories. The adjustment process of "flow" is not only pneumatic control, but also a part of pneumatic system.

Pneumatic system:

In the pneumatic system, the pneumatic generator is generally an air compressor, which converts the mechanical energy provided by the prime mover into the pressure energy of gas; Pneumatic actuator converts pressure energy into mechanical energy to complete the specified action; Between these two parts, various control elements (pressure control valve, flow control valve, direction control valve and logic element), sensing elements and pneumatic accessories are connected in a certain order according to the requirements of working cycle movement of machinery or equipment.

General application of pneumatic control;

The doors of passengers getting on and off are all pneumatically controlled, and the "pressure reducing valve" on the gas storage tank plays the role of regulating "pressure".
