Introduction: Duckbill valve is often called duckbill valve because its shape is like a duck's beak. Duckbill valve is the common name of rubber blowdown check valve. It is improved on the basis of the production of Ross valve company in Spain and red valve company of America. Duckbill valve products have flange connection and clamp connection

  Duckbill valve Because the shape of the valve is like a duck's beak, it is often called Duckbill valve The duckbill valve is Rubber drain check valve It's in Spain

Based on the production of Ross valve company and red valve company of the United States, the improvement is carried out. Duckbill valve products have flange connection and clamp connection.

The drain valve is widely used in urban drainage system. Duckbill valve is an integral structure, 99.5% rubber material, built-in nylon cord rubber layer, without any mechanical accessories. Valve opening and closing characteristics are good, only through the internal pipeline pressure and external back pressure to control the valve opening and closing, no other operating parts, no need for manpower or power. The valve can completely prevent sewage corrosion. When the valve is closed, the leakage is zero and the sealing performance is good. Rubber drain check valve (duckbill valve) is widely used in beach, coast, wharf flood, waste water, and coastal city sewage discharge. Rubber blowdown check valve (duckbill valve) can replace flap valve. It is suggested that the rubber blowdown check valve below DN800 can be connected by clamp or flange. Flange connection is recommended for rubber blowdown check valve above DN800. Rubber duckbill valve The valve is made of rubber structure with good elastic rubber material and built-in reinforced fiber. According to the stress analysis and stress calculation, it adopts different design mechanism, selects different rubber formula, and is made according to special process. Its valve body is particularly flexible, which can ensure a large degree of pressure resistance, at the same time, ensure small hydraulic loss, and achieve discharge and compression resistance The perfect combination of sex.

The following is the summary of the clamp type by the technicians of Shanghai Luoying pipeline equipment Co., Ltd Flange duckbill valve Scope of application: it is applicable to the drainage system, which can prevent the flood from flowing back into the urban surface, sewage treatment plant and drainage pump station when the water level rises; it is applicable to the sewage pool discharge, which can prevent the sewage from flowing into another water section of the embedded pool. In the untreated sewage, the normal operation of the valve will not be affected by plastic, tree branches or silk fabrics, etc.; it is suitable for the pumping station system, used for large drainage pump stations, to prevent the backflow after the pump stops. It is of all rubber structure Clamp type duckbill valve It can prevent the corrosion of sea water and reduce the head loss; it is suitable for the drainage of airport and expressway, which can effectively prevent the backflow; it is suitable for the sewage system, which can prevent the flood and sewage from flowing back into the sewer and basement, and avoid the heavy loss; the odor is blocked in the pipeline Clamp type duckbill valve It can prevent the odor diffusion of sewage or odorous fluid, and can drain water at any time; it is suitable for dam discharge and rock beach discharge, and the problems troubling the clapper door are as follows: the clapper door can not be closed or opened due to the blockage of stone waste; these problems will be solved thoroughly by using the clamp type duckbill valve in these areas; it is suitable for sewage discharge, and can prevent from flowing from urban sewer in rainy season To the city streets. The clamp type duckbill valve is an ideal choice for municipal and factory aeration systems.
