Description

[0002] A valve is a device used to control the direction, pressure, and flow of a fluid. It is a device that allows the medium in the piping and equipment to flow or stop and can control its flow. The sealing performance of a valve is the most important technical performance indicator of a valve. The main factors affecting the sealing performance of a valve are the material of the seal and the surface accuracy of the valve opening and closing parts. The opening and closing parts of a valve are mainly composed of a valve disc and a valve seat. Improving the surface accuracy of the valve opening and closing parts mainly involves improving the surface accuracy of the valve disc and valve seat. During the use of the valve, if the valve disc and valve seat are damaged, it is easy to cause leakage. At this time, the surface accuracy of the valve disc and valve seat can be improved by repairing the valve disc and valve seat to restore its sealing performance. Improving the surface accuracy of the valve disc and valve seat is mainly achieved through grinding.
