Rubber Check Valve
a: Rubber Check Valve Product Introduction
1:Rubber check valve is made of rubber ,it looks like a duckbill and is a new draining valve with functions of forward inflow and reverse back stop.
2:Based on analysis and calculation of stress,the product is made via special process with different design principles,different rubber prescription under different operating conditions.During the forward operation,water flows in from the inlet,and the lower water pressure will open the valve,the higher the water pressure is,the wider the valve is opened ,and the higher the water flow is.
3:During the back stop operation,the valve will vclose naturally,seal and stop.The higher the water pressure is,the tighter the valve is,the better the sealing effect.The product is widely used in draining water of municipal construction,water conservancy and seawage process so as to prevent reverse flow and reflux,it is an ideal product to replace flat valves.
b:Rubber Check Valve Charateristics
Compared with traditional flat valves,it owns obvious advantages:
1 It will start and close automatically according to the differential water pressure,safe,reliable,noiseless,no manual operation or maintenance
2 There is smller resistence in forward start,small pressure to start,in addition,the flux can be adjusted automatically according to the water pressure.
3 There is sound seal for back stop,no leakage,back flow prevention,the higher the back pressure is ,the better the effect is.
4 Corrosion protection,aging protection,no deformation,high adaption and long service life
5 Wide size,norminal size:DN50~DN3000mm
