Description

 the lift check valve is generally similar to that of the globe (stop) valve, and its valve disc rises and falls along the center line of the channel. Sealing principle: when closing, it depends on its own weight. Once the valve disc is closed, it acts on the valve disc by the pressure of medium countercurrent to form a sealing pressure. The higher the pressure, the higher the sealing pressure on the sealing surface of the valve plate and the valve seat, and the easier the sealing
