    Clamp type Duckbill valve It is a new type of water supply and drainage valve product with special structure and "duck beak shape" and "forward discharge and reverse check" function. The valve does not have any moving components and is free of maintenance. It can be used for straight pipe, flange pipe, cement pipe and glass fiber reinforced plastic pipe. It is widely used in various outlet outlets such as coast, beach, wharf, reservoir, municipal flood discharge, sewage pool discharge, odor barrier, pumping station system, etc.

    The clamp type duckbill valve has the advantages of buffering, silencing, maintenance free and corrosion-free. It is much better than flap valve in sealing performance, working performance in harsh environment and improving seawater purification performance. It solves the technical problems of traditional flap valve or butterfly check valve, such as poor operation condition, large leakage, valve seat wear, deformation and corrosion of parts, noise and frequent maintenance and replacement due to many mechanical failures. It's called green valve. Clamp type duckbill valve is used in sewage system, discharge system, pump outlet, lifting pump station and submerged aeration system.
    The elastic rubber structure of this product is made of stainless steel or wear-resistant and corrosion-resistant materials; it is free of maintenance and can prevent backflow; solid particles can still be closed tightly; it will not freeze when opening and closing; the opening head loss is small; it is customized for the special requirements of customers, durable and long service life, up to 50 years. Chloroprene rubber, butadiene rubber, fluororubber and other materials for production.
    Different from the former fixed round pipe outlet, the jet velocity and outlet flow rate of the clamp type duckbill valve have a complex nonlinear relationship. The test shows that the flow velocity required for the effective mixing of the sewage discharged by the clamp duckbill valve is much smaller than that required by the same mixing in the circular pipe A general two-dimensional internal dynamic calculation formula is obtained by analyzing the experimental data. The experimental results show that the diffusion is more stable, the jet velocity is high and the energy is also large. The laser velocimetry technology is used to measure the mixing area of the duckbill valve The results show that the duck beak shaped nozzle has better diffusion effect than the standard round nozzle.
    The special shape structure of clamp type duckbill valve makes it convenient and quick to prevent backflow and backflow, saving time and effort. And because of its simple structure, it almost does not need to spend any maintenance work in the use process. Luoying clamp type duckbill valve is designed according to the national standard, with good quality, good price, strong and durable, sufficient elasticity, and has the function of "positive inflow, reverse check"
