Duckbill Check Valve is generally made of natural rubber or chloroprene rubber and artificial fiber through special processing. Because the appearance looks like duck's mouth and the front end is flat, it is called duckbill check valve.Classification of duckbill check valve:According to the connection mode, it is generally divided into flange duckbill valve and clamp duckbill valve;According to the material, it can be divided into natural rubber duckbill valve and neoprene duckbill valve.
Function of duckbill check valve
In the process of use, when the internal pressure of the pipeline increases gradually, the outlet of the duckbill valve will gradually expand and open, and the medium of the pipeline will be discharged at high speed. When there is no internal pressure, the outlet of the duckbill valve will be closed under the effect of its own material elasticity, and the external medium will not enter the pipeline through the outlet of the duckbill valve, so as to prevent the sewage from pouring So it will be called duckbill check valve.
Features & Benefits of duckbill check valve
1. Automatic switch of duckbill check valve pressure difference, safe and reliable, no noise, no need of personnel operation, no need of maintenance.
2. The forward steering resistance is small, and the starting pressure and flow are adjusted naturally according to the water pressure.
3. Duckbill check valvecheck seal, no leakage, prevent backflow, the greater the back pressure, the better the effect.
4. The rubber of duckbill check valve is resistant to corrosion, aging, deformation, strong adaptability and long service life.
5. Compared with other check valves, duckbill check valve has the same function and lower price.
6. The duckbill check valve is easy to install and maintain.
7. The duckbill check valve is light in weight, small in volume and convenient in transportation.
However, due to the limitation of material, Duckbill check valve also has some disadvantages. For example, the rubber of duckbill check valve is easy to crack when it is placed outdoors for a long time; it is not resistant to high temperature and easy to accelerate aging; outdoor sunlight and ozone will shorten the service life of the product. Therefore, according to the characteristics of duckbill check valves, we must pay attention to the use and storage methods of duckbill check valves, avoid collision and sharp tool scratch, keep away from high temperature and high temperature, and often check and maintain duckbill check valves outdoors.
