High-pressure ball valves are important equipment in hydraulic systems, especially in industries such as steel mills, petroleum, chemical, gas, boilers, papermaking, textiles, medicine, food, ships, water supply and drainage, energy, polysilicon, and electric power. High-pressure ball valves are used for industrial pipelines. The correct and reasonable use of high-pressure ball valves, the mastery of high-pressure ball valve fault diagnosis methods and rapid elimination measures and means are vital to the industrial pipeline of the hydraulic system. Once the equipment fails, it must be quickly eliminated to ensure the normal and stable production.
Prevent the drive shaft of the high pressure ball valve from being affected by radial forces
The valve drive shaft is very sensitive to radial forces. Therefore, it is not allowed to directly install belt wheels, gears, and sprockets on the drive shaft end of the motor, and the coaxiality of the prime mover output shaft and the high pressure ball valve drive shaft must be checked during installation. In order to avoid the wedge-shaped gap between the valve body and the valve plate caused by the bending of the drive shaft, increase leakage, reduce the volumetric efficiency, aggravate the wear between the valve body and the valve plate, and seriously affect the efficiency and service life of the high-pressure ball valve.
