Check valve refers to the opening and closing parts for the circular disc and by its own weight and medium pressure to produce action to block the medium backflow of a valve. It is an automatic valve, also known as check valve, check valve, return valve or isolation valve. The movement mode of the valve is divided into lifting type and swing type. Lift CHECK VALVES ARE SIMILAR IN CONSTRUCTION TO GLOBE VALVES EXCEPT THAT THEY LACK the stem THAT DRIVES THE DISC. The medium 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 disc weight and its flow resistance. On the contrary, the valve is closed when the medium backflows. Swing CHECK VALVES HAVE a disc THAT IS TILTED and ROTATES ABOUT ITS axis and OPERATE on a similar PRINCIPLE AS LIFT CHECK VALVES. The check valve is commonly used as the bottom valve of the pumping device to prevent the return of water. The combination of check valve and globe valve can play the role of safety isolation. Disadvantages are high resistance, poor sealing when closed.
