Pneumatic diaphragm valve leakage is what circumstance?

Pneumatic diaphragm valve is often used in the production of our work at ordinary times, but, you know its true? It usually appears some problem you can solve? Then give you a simple talk about the main reason for the pneumatic diaphragm valve leakage, hope to be of help.




pneumatic diaphragm valve in the process of opening and closing to bear greater pressure, sudden movement cause changes in the flow state, the pneumatic diaphragm valve gradually from closed to open crack formation, the effects of the shear flow on the disc, the disc edge cutting, multiple role could make the aprons fall off or broken, and will give my gap, gate, the phenomenon of the pneumatic valve is lax





1, the quality problem itself, ram, the lock body fall off coating or coating thin gate body, disc, rust, the thickest 30-50 millimeters, the gate shut not move or damage due to rust block slag on the lock body sealing strip, pneumatic valve is lax. O-ring seal quality defects, installation is firm or thickness is too thin to make the gasket in the process of dynamic brake off;





2, long-term fixed and pneumatic diaphragm pneumatic valve maintenance does not reach the designated position caused by pneumatic diaphragm valve operating difficulties, pneumatic valve pneumatic diaphragm inactivity or do not maintain for a long time, cause brake head or ram corrosion is serious, rust scale after shedding pneumatic diaphragm pneumatic valve is lax, action inconvenience.
