Check valve is a valve that uses the pressure difference between the medium before and after the valve to automatically open and close and control the one-way flow of medium, also known as check valve or one-way valve.
According to different structures, check valves are divided into lifting type (jumping type) and swing type (polar type).
Lifting and swing type
Precautions for use:
Pay attention to the direction of the valve. The arrow is consistent with the flow direction of the medium. If the medium is easy to crystallize, the valve plate may not be pressed down and can not play the role of command and check.
