Introduction to curved bill duckbill valve
The main purpose of the curved bill duckbill valve is to be used in sewage treatment, drainage systems, water pump outlet lifting pump stations, and underwater systems.
The main features of the curved bill duckbill valve are: 100% elastic rubber structure, maintenance free, preventing backflow, and the solid particle blockage can still be tightly closed; Will not freeze during opening and closing; Low head loss when opening; It can be customized for different working conditions and material requirements of users, with durability and long service life.
The production materials of the curved bill duckbill valve include chloroprene rubber, nitrile rubber, fluororubber, etc.
Elastic rubber structure, which will not deform or freeze during opening and closing. No rust or corrosion, no backflow device.
Stay: The inner diameter of the rubber slow closing check valve (rubber duckbill valve) clamp should match the outer diameter of the connecting pipeline correctly.
The rubber slow closing check valve (rubber duckbill valve) is sleeved on the connecting pipeline with steel or stainless steel, and according to the standard, the rubber slow closing check valve of 18 "and above (450) meters is a semi arc type.
Installation size and method of curved bill duckbill valve: The XL-T (F.S) rubber drain check valve adopts a sleeve design at the valve body installation site, which is inserted into the matching connecting pipeline. The pipeline and the inner wall of the sleeve can be sealed with waterproof glue and metal clamps can be used. Gaskets should be added appropriately between the clamps and clamps, and connecting bolts should be tightened. If auxiliary lining pipes are used, they should be sealed and welded with the reserved pipeline during connection. When the nominal diameter is greater than DN800, due to the large weight of the valve body and the impact of a large amount of water and water flow in the abdominal cavity of the valve body during operation, a supporting rod must be added. Hang the valve body firmly for a long time (all valve bodies above DN800 have lifting rings)
