The rubber flap check valve consists of a valve body, a valve cover and a valve flap. It is mainly used at the pipe outlet of the water supply and drainage system, petroleum, chemical industry and other industrial sectors to prevent the backflow of the medium. Due to the inclined design of the sealing ring of this product, the closing time is short, which can reduce the water hammer pressure. The valve disc is made of nitrile rubber and steel plate by high temperature pressing, which is resistant to erosion and has good sealing performance. The product structure is simple, maintenance, repair and transportation are very convenient. The rubber disc check valve adopts a built-in rocker arm swing structure, the disc rotates around the rotating shaft, the disc is opened under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve disc will automatically close under the action of fluid pressure difference, gravity and other factors to prevent the fluid from flowing back.
