What is a built-in clamp duckbill check valve?

The built-in Clamp Duckbill Check Valve is one of the rubber check valves. The built-in Clamp Type Duckbill Valve is different from the Flanged Duckbill Valve in that it adds a metal cavity on the basis of the flanged flexible check Valve, with flanges at both ends, and can replace the traditional pipeline check valve. Compared with other check valves, the Built-in Duckbill Valve is highly reliable, maintenance-free, light in weight, easy to install and operate, and can be directly connected to the pipeline Flange and bolted.

The built-in Duckbill Valve is generally installed and used on coastal embankments and the banks of rivers and lakes. In these areas, the phenomenon of rising water levels and flooding drainage pipes due to high tides or river siltation often occurs. The built-in Clamp Type Rubber Duckbill Check Valve completely solves this problem. Even if the water level rises and floods the outlet of the pipe, when the internal medium of the pipe installed with the duckbill valve accumulates to a certain amount, it can well discharge the internal medium by relying on its own pressure, and then rely on external force to tightly close the duckbill valve, thus achieving the effect of drainage check.

 

During the installation of the built-in duckbill valve, you should choose a duckbill valve product that is consistent with the diameter of the pipeline. The duckbill valve should be installed into the interior of the pipeline system. After it is installed in the appropriate position, the end of the duckbill valve should be tightened with the internal support clamp, and the duckbill valve should be fixed to the inside of the pipeline with the expansion bolt. This completes the installation. Secondly, during the installation process, the duckbill valve mouth should be fixed in a directional manner according to the flow direction of the pipeline medium to avoid backflow and check valve.
