Two common faults of fluorine lined check valve

    check valve It is applied in water supply pipeline systems in various industries, mainly to prevent liquid backflow. Its characteristics are short structural length, small volume, light weight, strong sealing, and long service life. There are two common faults in the use of fluorine lined check valves, namely valve disc breakage and medium backflow.
For valve disc breakage, it is caused by the valve disc being hit by the valve seat, mainly due to the pressure of the medium before and after the fluorine lined check valve being in a relatively balanced but mutually "sawing" state. At this time, the valve seat will continuously hit the valve disc, eventually breaking it. This situation is difficult to prevent, and a more effective solution is to use materials with strong toughness to manufacture the valve disc.
There are generally two reasons for medium backflow: one is that the sealing surface is damaged, and the other is that impurities are trapped in the sealing surface. The solution is to repair or clean the sealing surface.
The above is an analysis of the causes and solutions to two common faults of fluorine lined check valves, hoping to be helpful to everyone.
