    Xh81a sewage Rubber check 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 is maintenance free and has no components. 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.

    Xh81a rubber check valve for blowdown 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.
    Xh81a rubber check valve can effectively prevent backflow, backflow and sediment formation. Different from the former fixed round pipe outlet, the jet velocity of the clamp duck beak valve has a complex nonlinear relationship with the outlet flow, The velocity required for effective mixing of sewage discharged by xh81a rubber check valve is much smaller than that required by the same mixing in circular pipe. Various tests are carried out on the flow characteristics of different valve ports, and a general two-dimensional internal dynamic calculation formula is obtained by analyzing the test data. The test results show that the clamp duck beak type is used The results show that the duckbill nozzle has better diffusion effect than the standard round nozzle.
    The special shape structure of xh81a rubber check valve makes it easy 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 xh81a blowdown rubber check valve is designed according to the national standard. It has good quality, good price, strong and durable, and has the function of "positive inflow, reverse check"
