Two Common Faults Of Fluorine-lined Check Valves

Lined Check Valve is used in water supply pipeline systems in various industries and fields, mainly to prevent liquid backflow. Its characteristics are short structural length, small size, 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, the valve disc is slapped by the valve seat, causing it to break. This is mainly because the pressure of the medium before and after the fluorine-lined check valve is in a relatively balanced but mutually "sawed" state. At this time, the valve seat will keep slapping the valve disc and finally break it. This situation is difficult to prevent. The more effective solution can only be to use materials with strong toughness to manufacture the valve disc.
There are generally two reasons for the backflow of the medium. One is that the sealing surface is damaged, and the other is that impurities are sandwiched in the sealing surface. The solution is to repair or clean the sealing surface.
The above is an analysis of the causes and solutions of the two common faults of fluorine-lined check valves. I hope it will be helpful to everyone.
