What are the self-help type pneumatic control valve repair content?

What are the self-help type pneumatic control valve repair content? Answer: self-reliance type pneumatic control valve of common faults mainly for decompression performance failures and two aspects of the body and bonnet, end cover joint leakage. Self-reliance in the operation type pneumatic control valve failure in need of repair, should be shut down on either side of the pressure reducing valve self-reliance type pneumatic control valve, the by-pass pipe work for the time being. At ordinary times should be regular inspection on self-reliance type pneumatic control valve repair, reduce the failure rate. Self-reliance type pneumatic control valve regularly check the content is: check the wear condition of the main valve and pulse valve, spring and diaphragm is tired, whether the cylinder wear or corrosion, piston ring is loss of tension, etc. The conditions of use and performance of the various self-help type pneumatic control valve is what? What general workshop self-reliance type pneumatic control valve? A: self-reliance type pneumatic control valve is suitable for the relatively stable low pressure gas, the pressure of the user. Usually adopt self-reliance type pneumatic control valve are: piston self-reliance type pneumatic control valve, diaphragm spring self-reliance self-reliance type pneumatic control valve, corrugated type type pneumatic control valve, QZY air filter self-reliance type pneumatic control valve, QJY precision instrument self-reliance type pneumatic control valve, the conditions of use and performance are shown in table 5 - 9. General car mostly living cold type of self-help type pneumatic control valve, piston type pneumatic control valve installation as shown in figure 5 - themselves 5.
