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.
Check valves of this type function to allow flow of the medium in one direction only, but to prevent flow in the opposite direction. Typically such valves are self-actuating, with the flap opening under the pressure of a fluid flowing in one direction; when the fluid flows in the opposite direction, the valve flap is combined by the fluid pressure and the self-weight of the valve flap to act on the valve seat, thereby cutting off the flow.
Because the fluid usually has a large pressure, turbulent flow is easily formed in the valve body, and directly erodes the valve wall, which causes the phenomenon of valve diameter enlargement, thereby causing damage to the valve body, affecting the sealing performance of the sealing valve body, and needing to buffer the fluid to resist the fluid erosion.
