Regardless of the valve, the sealing surface zui is easily destroyed, and problems such as insertion, bruise, and crushing may occur during the switching process. Forged steel ball valve is easy to infiltrate the atoms of the two sealing surfaces under the action of high pressure, resulting in adhesion phenomenon; if the two covers are moved, your adhesion and tearing will occur, especially in the case where the surface roughness of the sealing surface is higher. occur. If the forged steel ball valve is bumped or crushed during the sealing process, the sealing surface is partially worn or indented.
The effect of abrasion, rinsing, and cavitation on the sealing surface during the movement of the medium is called “erosion of the mediumâ€. Such a situation often causes partial damage, so the quality of the sealing surface must be processed well. Under the alternating action of medium erosion and chemical erosion, this is a strong erosion of the sealing surface. In addition to natural damage, the sealing surface is also damaged by human beings. The causes of human damage are caused by many factors such as poor design, poor manufacturing, improper material selection, incorrect installation, improper use and insufficient maintenance, etc.; therefore, these conditions must be avoided. When it occurs, the ball valve can be used without any problems, and the life of the ball valve can be guaranteed.
