The structure characteristic of plunger valve is controlled by a stainless steel piston and the upper and lower two elastic sealing ring, sealing ring and fixed up and down and can keep the distance of metal framework, plunger is like a cork generally inserted into the two sealing ring formed in the cylindrical contact seal, the sealing area is large than traditional cut-off valve, sealing efficiency is very high, the sealing ring to prevent external leakage, plays a role of inner seal ring, if after a long time with leakage, pressure can be covered by adjusting the retaining bolt (valve mouth closed) first make the seal ring on the seal pressure increase, caused by the component increases, The seal ring that makes it leak is heavy machine press to restore seal, our factory passes the seal test of many times of interference close batch to cooperate, determined reasonable interference seal value, through reciprocating movement millions of times, still can provide good seal effect reliably.
