Discusses why a screw air compressor's safety valve may not return after activation and provides solutions.

Butiran Kes

Answer: (1) Fault phenomenon. The safety valve leaks after being activated.

(2) Cause analysis.

1) The contact surface between the valve core and the valve seat is not tight;

2) There is dirt on the contact surface between the valve core and the valve seat, and scale, scale, debris, etc. fall on the sealing surface;

3) The valve stem is deflected, the valve stem is bent and deformed, or the valve core and the valve seat support surface are deflected;

4) The sealing surface is mechanically damaged or corroded;

5) The spring fails due to excessive load or the spring elasticity is reduced due to corrosion.

(3) Elimination method.

1) Adjust the contact surface between the valve seat and the valve core;

2) Use manual exhaust (steam) to blow or disassemble and clean;

3) Reassemble or replace the valve stem;

4) Grind or turn the sealing surface;

5) Replace the spring.
