Duckbill Check Valve is a new type of water supply and drainage valve product with a full rubber structure, a duckbill shaped shape, and a "forward flow, reverse check" function. It is made according to force analysis and force calculation, using different design mechanisms for different working conditions, selecting different rubber formulas, and following special processes. When working in the forward direction, water flows into the inlet, and a small water pressure can open the valve. The higher the water pressure, the greater the valve opening and the greater the water flow rate. When working in reverse, the valve port naturally closes and is sealed in reverse. The greater the back pressure, the tighter the valve port, and the better the sealing effect. It is widely used in various discharge outlets such as municipal, water conservancy, sewage treatment, etc., to prevent backflow and backflow, and is an ideal product to replace flap doors.
