Fluorine lined ball valves have been widely used in the valve industry. Due to their excellent sealing, safety, low resistance, and strong flow capacity, fluorine lined ball valves are inevitably damaged during use, and problems such as insertion, collision, and squeezing may occur during the switching process.

Explosion proof electric fluorine lined ball valves are prone to cause the atoms on the two sealing surfaces to penetrate each other under high pressure, resulting in adhesion; If you move the two covers, there will be adhesion and tearing, especially when the surface roughness of the sealing surface is higher, which is more likely to occur. If the fluorine lined ball valve is hit or squeezed during the sealing process, causing local wear or indentation on the sealing surface.

The explosion-proof electric fluorine lined ball valve medium is prone to wear, flushing, and cavitation on the sealing surface during movement, which is called "medium erosion". This situation often causes local damage, so the quality of the sealing surface must be well processed. Under the alternating action of medium erosion and chemical erosion, the sealing surface will be strongly corroded.

In addition to natural damage, there is also human damage to the sealing surface, which can be caused by many factors such as poor design, poor manufacturing, improper material selection, incorrect installation, improper use, and insufficient maintenance; So it is necessary to avoid these situations in order to avoid any problems when using the ball valve and ensure its lifespan.

Mechanical damage, such as scratches, bumps, and squeezing on the sealing surface during the switching process. Between the two sealing surfaces, atoms undergo mutual infiltration and leakage under high pressure, resulting in adhesion. When the two sealing surfaces move towards each other, the adhesive area is easily pulled apart. The higher the roughness of the sealing surface, the more easily this phenomenon occurs. The explosion-proof electric fluorine lined ball valve may collide and crush the sealing surface during the sealing process and the ball center during the reseating process, causing local wear or pressure marks on the sealing surface.
