Structural principle of pneumatic actuator（1）

Structural Principle:

The types and structures of adjustment mechanisms for pneumatic actuators are roughly the same, mainly due to differences in the execution mechanisms. Therefore, in the introduction of pneumatic actuators, there are two parts: the actuator and the regulating valve. The pneumatic actuator consists of two parts: the actuator and the regulating valve (regulating mechanism). According to the magnitude of the control signal, generate corresponding thrust and push the regulating valve to operate. The regulating valve is the regulating part of the pneumatic actuator. Under the action of the actuator thrust, the regulating valve produces a certain displacement or angle, directly regulating the flow rate of the fluid.

 

Working Principle:

The working principle of pneumatic actuators is to convert air pressure energy into mechanical energy through the action of compressed air, and drive valves or actuators to open, close, adjust and other actions. The internal components of pneumatic actuators include cylinders, pistons, valves, and control components, among which the cylinder is the most core component. It pushes the piston through the action of air pressure, thereby driving the movement of the valve.
