The basic building blocks of pneumatic actuators

Pneumatic actuators by actuator and control valve ( Regulatory agencies) The two parts. According to the size of the control signal, generate the corresponding thrust, promote regulator action. Regulating valve is to adjust part of the pneumatic actuators, in under the action of thrust actuator, valve produce certain displacement or corner, regulating the flow of fluid directly.





internal structure of pneumatic actuator


1, the pneumatic device is mainly composed of cylinder, piston, gear shaft, end cover, seals, screws, etc; Complete sets of pneumatic device should also include the opening instructions, limit, solenoid valve, locator, pneumatic components, manual institutions, and signal feedback etc parts.


2, pneumatic device connected to the valve size should meet with ISO5211 ( At the bottom) , GB/T12222 and GB/T12223 rules.


3, with manual mechanism of pneumatic device, the gas source is interrupted, should use pneumatic ball valve opening and closing operation, manual mechanism for the handwheel, should the handwheel or handle counterclockwise for valve open, clockwise for the valve to close.


4, piston rod end for internal and external thread, should be over the spanner wrench.


5, the piston sealing ring should be easy to replace and maintenance.


6, buffering mechanism of pneumatic device, the stroke length of the buffering mechanism can be reference to the provisions of the table 1.


7, with adjustable buffering mechanism of pneumatic device, shall have the external cylinder body adjust the institutions of the cushion.


8, in and out of the air cylinder thread sizes should be consistent with MANUR NORM ( Attachment standard) sypv, GB / T7306。 1 GB / T7306。 2 and the provisions of GB/T7307.
