Background
The silencing check valve is a valve which automatically opens and closes a valve clack by medium flowing, and is used for preventing the medium from flowing backwards, and is also called a check valve, a one-way valve, a silencing check valve and a back pressure valve. The check valve is an automatic valve and mainly used for preventing medium from flowing backwards, preventing the pump and a driving motor from reversing and discharging container medium. Check valves may also be used to provide make-up lines to auxiliary systems where the pressure may rise above the system pressure. The check valve can be mainly divided into a swing check valve and a lift check valve. The poppet check valve is similar in construction to a shut-off valve in that media flows in from the inlet end (lower side) and 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. The inside deposit that can remain of valve body after check valve installation uses a period to the pipeline, and the deposit can be attached to the valve body inner wall, and the deposit can constantly pile up, influences the valve and goes out water. Meanwhile, partial sediments attached to the inner wall of the valve body can erode the inner wall of the valve body, and the service life of the valve body is shortened.
