Research on Ball Grinding Equipment for Advanced Hard Seal Pneumatic Ball Valve? In recent years, with the demand of various high-temperature environments and harsh fluid medium environments with particles, hard sealed pneumatic ball valves are increasingly widely used in various process pipelines and devices. It not only expands the capacity demand, but also reduces energy consumption and improves production efficiency. Production of advanced hard seal pneumatic ball valve, pneumatic ball valve ball processing accuracy directly affects the pneumatic ball valve technical indicators of good or bad. Pneumatic ball valve is a device for opening and closing various liquid and gas medium pipelines. At the same time, it has the function of controlling the flow and changing the direction. In order to complete the above functions, the pneumatic ball valve is mainly used. The rotation of the ball in the valve body makes the sealing pair close to the surface of the ball with the help of the elasticity of the elastic element to meet the working conditions. Especially for the hard sealed pneumatic ball valve working under high temperature and pressure, because the ball needs to rotate, the non-circular degree and surface roughness of the hard sealed ball directly affect the flexibility, service life, leakage and other problems of the switch. So how to improve the roundness and surface roughness of the ball of the advanced hard seal pneumatic ball valve is very important. Research on ball grinding equipment for advanced hard seal pneumatic ball valve the base part is generally cast from medium carbon steel and stainless steel according to customers and working conditions. Surface nitriding, spraying alloy treatment. The surface hardness shall be higher than HRC60. After the surface hardening treatment of the sphere, especially the larger sphere, there will be some geometric deformation. The surface roughness decreases, and grinding is required,

3. Inspection of pneumatic ball valve after installation
(1) Operate the driver to open and close the pneumatic ball valve for several times, which should be flexible without stagnation, to verify that it works normally.
(2) The design of connecting pipeline requires that the sealing performance of the flange joint surface between the pipeline and the spherical jaw should be checked.
