Analysis of two common failures of American standard check valve

     The American standard check valve is also called a check valve or one-way valve because it prevents the medium in the pipeline from flowing back. The opening and closing part of the American standard check valve is the valve clack, which relies on the flow and force of the medium to open and close by itself, so it belongs to the automatic valve category. American standard check valves are often used in pipelines that require the medium to flow in one direction, and only allow the medium to flow in one direction, avoiding unnecessary accidents.

     In the process of using the American standard check valve, various problems will be encountered. Below, the technical staff of the American standard check valve manufacturer summarizes the failure of the American standard check valve to provide you with a useful reference.

     Two common failures of American standard check valve:

     Failure one, the valve disc is broken

     Reason analysis: The medium pressure before and after the American standard check valve is in a balanced and saw state. The disc and the valve seat often collide together. If the material is brittle, it will be broken.

     Solution: Choose tough material for disc.

     Fault two, medium backflow

     Reason analysis: the sealing surface is damaged or the medium is inserted.

     Solution: Repair the sealing surface and feel the impurities clearly.
