活塞密封式安全阀

A safety valve based on piston sealed type

介绍了一种新型的活塞密封式安全阀,该阀开启、排放和回座动作灵敏平稳,启闭压差为零,且没有阀瓣频繁跳动现象。

A kind of safety valve based on piston sealed type is introduced in paper.The safety valve is adopted by piston sealed type instead of valve flap sealed type,and the action is not only sensitive to be done but also the valve flap has no jumpiness when it is turned on,released and turned back because differential pressure of opening and closing is zero.
