Background

The check valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards. It belongs to the automatic valve category, also called check valve, reflux valve or isolation valve. The valve clack motion mode is divided into lifting type and swing type. The lift check valve is similar in structure to the stop valve and only lacks a valve rod that drives the valve flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. Swing check valves have a flap that is tilted and can pivot, and operate on a similar principle to lift check valves. At present, the high-sealing high-pressure check valve has higher installation requirement and good sealing performance, but in the prior art, the high-sealing high-pressure check valve is troublesome to operate during installation, has poor sealing effect after installation and is easy to leak.
