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,

Pneumatic butterfly valve is popular because it can reduce pipeline installation
Pneumatic butterfly valve is a pipe fitting that uses the central element of corrugated pipe to deliver various fluids, and mainly plays a compensation role in the connection between pipes, pipes and equipment, and equipment and equipment. At present, pneumatic butterfly valve has been widely used in many complex pipeline systems. Pneumatic butterfly valve can reduce pipeline installation stress, which is a popular important element.
In a complex pipeline system, there are often various difficulties in installation due to the restrictions of space and location conditions. The formed pipes cannot be installed, bent, and straightened. The pipes installed will be able to make up for the local cold correction. According to the pipe diameter and the details on site, the cold correction amount ranges from several millimeters to tens of millimeters, some hundreds of millimeters. Theoretically, the greater the amount, the higher the internal stress. These residual installation stresses in the pipeline system are undoubtedly a great hidden danger. Since the pneumatic butterfly valve can be bent at will and the internal stress generated by bending under the condition of rated bending radius is very small, it can bring great convenience to the installation work and play a role in the safe operation of the pipeline system. This is the main reason why some pipeline systems must use pneumatic butterfly valves.
In addition, the importance of pneumatic butterfly valve is also related to its excellent performance. Pneumatic butterfly valve has good flexibility, temperature resistance, pressure resistance and corrosion resistance, and plays an important role in the movement of pipe system, absorption of heat shrinkable joints and vibration absorption.
