The lower chamber is connected with the inlet chamber through a pipe 1, 进口水力控制阀the upper chamber is connected with the outlet chamber through a pipe 2, and an end stroke buffer device is arranged in the inlet chamber, When the pressure in the inlet chamber suddenly decreases and the medium in the pipeline flows backward, the medium in the outlet chamber enters the upper chamber through the pipeline 2. The pressure in the upper chamber gradually rises, the piston moves downward, and the valve flap closes slowly. The valve is installed in the pipeline to mainly control the reverse flow of the medium and eliminate the destructive water hammer caused by the sudden reverse flow of the medium. In addition, the valve flap rotates to the angle every time it is opened to close a movement cycle, The service life of the gasket can be improved.
