Rubber-lined check valve (also known as check valve) This type of valve only allows the medium to flow in one direction and prevents the direction from flowing. Usually, the valve is automatically operated, and the valve flap is opened by the fluid pressure flowing in one direction; when the fluid flows in the opposite direction, the fluid pressure and the self-reclosing valve flap of the valve disc act on the valve seat to cut off the flow. Among them, the rubber-lined check valve, the internal thread check valve, and the butterfly check valve belong to this type of valve.
