Flange type duckbill valve is a kind of duckbill valve and connected with flanges,has the advantages of light weight, convenient installation,long life and other characteristics, widely used in coast and beach, the terminal of the flood, waste water and no Haicheng city sewage drainage engineering, alternative now use products to shoot the door is the drainage industry ideal check valves products is well known and rubber under certain conditions, corrosion resistance.
Flange type duckbill valve need to pay attention to the details in the installation process
1.flange type duckbill valve should be kept in low temperature, dry place; avoid direct sunlight, prolong the service life. Set the floor or higher than the plane down, flange type duckbill valve in the installation process interface down to ensure the complete valve inside the garbage emptying, prevent sediment generation.
2 the valve should be far away from heat, ozone, oil, acid, alkali and regional; flange type duckbill valve body made of rubber should avoid the effect of high temperature environment on it.
3 it is strictly prohibited to strong radiation light exposure and bearing, because it is the main rubber, if bearing will caused by the bending deformation of the duckbill valve, or even broken.
4 sharp instruments are strictly forbidden to cut the surface;
5. "^" label on the box, do not allow the upside down or flat.
Flange type duckbill valve is widely used in city sewage drainage drainage system and sewage interception pipeline check valve. Duckbill valve is an integral structure,100% rubber material,built-in nylon layer,without any mechanical parts. Valve opening and closing the characteristics of good, only through the internal pipeline pressure and external pressure to control the valve opening and closing, do not need other operating components, nor need to human or power. Valve fully capable of corrosion, the valve is closed, the leakage is zero, good sealing performance. Gongyi HuanZhong production of flange type duckbill valve product quality conforms to the national standard, has good tensile strength, compressive properties, the quality of the products worthy of your trust
