Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy check valve. Background Art

[0002] A check valve is a valve whose opening and closing part is a circular disc and which relies on its own weight and medium pressure to produce movement to block the backflow of the medium. It is an automatic valve and is also called a non-return valve, one-way valve, reflux valve or isolation valve. The medium flows in from the inlet pipe and flows out from the outlet pipe. When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back.
