What are the advantages of flanged duckbill valves?

Duckbill valve, as the name implies, is a special structure with a duckbill shape. The valve body adopts an all-rubber design, and the rubber flange is linked to the valve body, which is easy to install and does not cause siltation and stuff jamming to occur, reducing maintenance costs.
In the process of use, when the internal pressure of the pipeline gradually increases, the outlet of the duckbill valve will gradually expand and open, 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 in the role of its own material elasticity, showing a closed state, and the external medium, is not through the outlet of the duckbill valve into the pipeline, to prevent sewage backflow, so it will be called a check valve. Can adapt to a variety of transmission media, because different areas have different transmission media, so the requirements of this duckbill valve is very high, but the duckbill valve is a full-body rubber structure of the duckbill valve, so as long as you change the duckbill valve production of raw materials, you can let him work in a variety of areas like fish in water, the full rubber characteristics of the achievement it can adapt to a variety of media.
Summarize the duckbill valve has the advantages of cushioning, sound-deadening performance, maintenance-free and non-corrosive. It is far better than the flapper door in sealing performance, working performance in harsh environment and improving the performance of seawater purification, solving the traditional flapper door or butterfly check valve due to many mechanical failure poor operating conditions, large leakage, seat wear, parts deformation and corrosion, noise, the need for frequent maintenance and replacement of technical problems. Can be described as green environmental protection valve.
