Xh81 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 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.
Xh81 rubber check valve has the advantages of buffering, noise reduction, 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.
This product has elastic rubber structure, the clamp 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; it has less loss of opening head; it is customized for customers' special requirements, durable and long service life, up to 50 years. Chloroprene rubber, butadiene rubber, fluororubber and other materials for production.
Xh81 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 test shows that the flow rate of the sewage discharged by the clamp duck mouth valve can reach the effective mixing, which is much smaller than that required by the same mixing of the circular pipe, The flow characteristics of different valve ports are tested, and the experimental data are analyzed, and a general two-dimensional internal dynamic calculation formula is obtained. These test results show that the use of clamp type duck beak valve can make the diffusion more stable, at the same time, the jet speed is large, and the energy is also large The results show that the duckbill shaped nozzle has better diffusion effect than the standard round nozzle.
The special shape and structure of xh81 rubber check valve make it easy to prevent backflow and backflow, save 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 and price, strong and durable, sufficient elasticity, and has the function of "positive inflow, reverse check"
