Clamp type duckbill valve
The clamp type duckbill valve is a new type of water supply and drainage valve product with a special structure and a duckbill shape, with positive discharge and reverse check function. The valve does not have any moving parts and is free of any maintenance. It can be used for straight pipe, flange pipe, cement pipe and glass steel pipe. It is widely used in various water discharge ports such as coast, beach, dock, reservoir, municipal flood discharge, sewage pool discharge, odor barrier, pump station system and so on. The clamped duckbill valve has the advantages of cushioning, noise reduction, maintenance-free and corrosion-free. Its sealing performance, harsh performance and improved seawater purification performance are far better than filming. It solves the problem of poor operation, large leakage, valve seat wear and part deformation due to many mechanical faults or butterfly check valves. And the technical problems of corrosion, noise, and frequent maintenance and replacement. It is called a green valve. The clamp type duckbill valve is used for sewage system, discharge system, pump outlet lifting pump station and submerged aeration system.
This product has 100% elastic rubber structure, the clamp is stainless steel or wear-resistant and corrosion-resistant material; maintenance-free, prevent backflow, solid particle jam can still be closed tightly; it will not freeze when opening and closing; less head loss is lost; The special requirements are customized, durable and long lasting for 50 years. Made of neoprene, nitrile rubber, fluoro rubber, etc.

The clamp type duckbill valve can effectively prevent reverse backflow and sediment formation. The difference from the conventional fixed pipe outlet is that the jet velocity of the clamped duckbill valve has a complex nonlinear relationship with the outlet flow rate. The flow rate of the sewage discharged by the clamped duckbill valve reaches the flow rate required for effective mixing, which is much smaller than the flow rate required for the same mixing of the circular pipe. Various tests are carried out on the flow characteristics of different valve ports, and these tests are simultaneously performed. The data were analyzed to obtain a general two-dimensional internal dynamics calculation formula. These test results show that the use of the clamp-type duckbill-shaped valve can make the diffusion more stable, and the jet velocity is large, the energy is also large, and the laser speed is measured. The technique studies the vicinity of the mixing area of the duckbill valve jet, and the results show that the duckbill-shaped discharge port has a better diffusion effect than the standard round nozzle.
The special shape structure of the clamp type duckbill valve makes it convenient and quick to prevent backflow irrigation, saving time and effort. And because of its simple structure, it does not require any maintenance work during use. The clamp type duckbill valve is designed according to national standards, with good quality and excellent price, strong and durable, and sufficient elasticity. It has the function of positive inflow and reverse backstop.
1 The structure of the rubber sewage check valve is novel, and it can realize the easy discharge of the sewage, and the reverse sewage can achieve an effective anti-reverse.
2The structure is simple, easy to install, and it is very convenient to use. It requires almost no maintenance process.
3 The product is made of rubber, with long service life and stable operation.
The 4 clamp type connection method is quick and convenient to install, which reduces the construction difficulty.
