Green new environmentally friendly valve: xh-type flexible check valve

    xh flexible check valve features:

    xh-type flexible check valve, also known as "duckbill valve, a special structure in shape the" duckbill shaped ", with" positive displacement flow, reverse-return "features new to the drain valve products. No active components of the valve, and the avoidance of maintenance. Can give a straight pipe, flange pipe, cement pipes, glass pipes supporting, widely used in coastal, beach, pier, reservoirs, municipal flood relief, cesspool emissions, odor barrier pump system effluent outfall.
wafer butterfly valves, wafer check valve, stainless steel ball valves

    xh-type flexible check valve prevents backflow intrusion and sediment generation, different from the previous fixed tube outlet: duckbill valve jet velocity and outlet flow was a complex nonlinear relationship, tests showed that duck sewage discharged by the nozzle valve to achieve effective mixing of the desired flow rate, the flow rate much smaller than the circular pipe of the same mixed required, subjected to various tests of different valve port flow characteristics, while analysis of these experimental data, obtained a general two-dimensional internal dynamics formula, the results of these tests show that use of the duckbill valve, enabling the proliferation of more stable, jet velocity, energy, the laser velocimetry duckbill valve Koupen jet a mixed region of the vicinity of the study, the results show that the discharge opening of the duckbill than the standard circular orifice has a better diffusion.

    xh-type flexible check valve has a buffer, silencer performance, maintenance-free and non-corrosive, etc.. Work performance and improve the performance of water purification in the sealing performance, harsh environment far better than shoot the door, to solve the traditional to shoot door or butterfly check valve poor health due to mechanical failure, leak, valve seat wear, warp and corrosion, noise, frequent maintenance and replacement of technical problems. Can be described as a green valve.
