Flexible Rubber Joint

Relying on rubber’s special performance as long range elasticity ,air impermeability ,medium ,climate and radiation resistance ,the product is manufacture through combination of inclined polyester cord fabric with high strength and cold and hot stability and molding cross linking under high pressure and temperature ,it has high density inside and can bear high pressure and has excellent elastic deformation .the product’s structural design in cross section are high ,curve length owns multi-function displacement .Especially , it is suitable to be used where there are complex geologic conditions and large sedimentation range and frequent cold and hot change that will damage pipes inside pipes .it can remove physical damage of displacement of pump ,valve and pipes through rubber’s flexible gliding shift and distorting mechanical heat transfer and relation .Rubber is a kind of low condition material ,so it can be ideal product for reducing librations and noise transfer .It is designed with smooth walls and has no influence on flow speed of medium in test and never rusts either .Therefore ,maintenance is not necessary in valid operation period..

flexible couping check valve  is a new water supply and drainage valve with full rubber structure ,”duck-mouthed” appearance and function of “positive flow –in and reserve-off”. According to thrust analysis and calculation as well as different operation condition .it is manufactured with different design mechanism and different rubber products by special processing .At positive operation the water flow in form entrance and the valve will be open at weak hydraulic pressure ;the hydraulic pressure id higher ,the valve gate will open more greatly and the water flow is greater .At reserve operation ,the valve gate closes naturally and seals tightly cut-off valve ;the back pressure is higher ,the valve gate closes more tightly and the seal effect is better .it is used widely in various drainage exit to prevent form pouring backwards and flowing backwards in city planning ,water conservancy and sewage disposal etc. it is the ideal product to replace flap valve.
