The principle of pneumatic pneumatic valve and daily maintenance

pneumatic pneumatic valve is driven by compressed air pneumatic valve, widely used in various fields. Pneumatic principle of the pneumatic valve

pneumatic regulating pneumatic valve is made up of actuators and regulating mechanism. Actuator is adjust the thrust part of pneumatic valve, it according to the size of the control signal pressure produce corresponding thrust, promote regulating mechanism. Pneumatic valve body is the adjustment of the pneumatic valve pneumatic control components, it is directly contact with control agent, regulating the flow of the fluid. Routine maintenance of

and pneumatic valve body ( Including variable speed drive cabinet inside and outside, should first deoxidization blasting derusting, strive for electrostatic spraying powder, non-toxic epoxy resin in thickness. Mm and above. Oversize pneumatic valve electrostatic spraying non-toxic epoxy resin are in trouble, should also be similar non-toxic epoxy paint brush, spraying.
、. Pneumatic valve body and internal pneumatic valve plate comprehensive anticorrosive parts requirements, on the one hand, soaking in the water will not rust, do not produce electrochemical corrosion between two metals; Two aspects of smooth surface reduce water resistance.
and pneumatic valve body of anticorrosive epoxy resin or paint the sanitary requirements, should have the corresponding authorities inspection report. Chemical properties also should comply with the related request.
