Vice-valve installed in the main valve side or both sides of the flap valve and the screw connection, the normal flow of media, the valve is opened, the medium pressure valve is opened by the Deputy, the medium through the valve hole into the main Double Door Check Valves, Air Cushion valve, Vice export side, so that the main valve inlet end of relief, the main valve valve flap to open, the main valve before and after the pressure balance; medium counter-current, the main valve valve valve in the counterflow medium under the action of fast closed, and the deputy valve body upper part of the buffer tank, the Deputy valve valve cap screwed the upper part of his body covered with a small hole, the Deputy valve valve valve with the piston rod sets have a certain air gap between the piston and the buffer cylinder with rubber O-ring seal, the piston and the valve flap between the lower-dimensional seal; as Vice-valve With the main valve valve valve valve valve was closed, because of Vice-valve valve cover the role of holes, the medium gradually flows through the small hole on the Vice-valve cylinder cushion cavity, part of the media, through the Deputy valve valve flap and the gap between the piston rod reflux, it is slow, Vice valve piston closed.
副阀安 装在主阀阀瓣下侧或两侧且用螺纹联接，介质正常流动阀门开启时，介质压力将副阀打开，介质通过副阀小孔流入主阀出口端，使主阀进水口端卸压，主阀阀瓣开启，主阀前后压力趋于平衡；介质逆流时，主阀阀瓣在逆流介质作用下快速关闭，而副阀阀体上部为缓冲缸，副阀阀盖旋入阀体上部其盖上有一小孔，副阀阀瓣与其活塞杆空套有一定间隙，活塞与缓冲缸之间采用O型橡胶圈密封，活塞下部与阀瓣之间为平面密封；当副阀阀瓣随主阀阀瓣关闭而关闭时，因副阀阀盖小孔的作用，介质通过小孔逐渐流入副阀缓冲缸上腔体，一部分介质通过副阀阀瓣与活塞杆之间的间隙倒流，故副阀活塞是缓慢关闭的。
