There are a lot of types of duckbill valve, generally divided into following kinds: flange duckbill valve, clamp duckbill valve, built-in duckbill valve and so on. Different connection methods of duckbill valve can meet the needs of various customers. Following are the advantages of duckbill valve installed in the emergency sea outfalls.
First of all, in discharged ocean engineering, most of discharge medium is sediment, but the duckbill valve belongs to rubber products, so according to the raw materials it can changed into IIR rubber, which makes wear-resisting performance best. So, for the sediment of sanding, duckbill valve also won't appear wear phenomenon.
Next, the performance of duckbill check valve is good. The working state of the duckbill valve is normal outflow and reverse check, with the change of the internal pressure to make the medium flow out and check by the size of the external pressure, no manual operation, and greatly reduces the use of manpower.
Finally, duckbill valve sealing performance is good, so the sealing condition is far greater than the other check valve. This is only one of its sealing characteristics. Its second sealing characteristic is that its working principle is according to the pressure change. So, when the external pressure is too large, his mouth will be closed tight. The greater the pressure is, the better the sealing effect is.
