Description

Technical Field

[0001] The invention relates to the technical field of eccentric valve processing, in particular to an eccentric valve body boring device. Background Art

[0002] As an indispensable key component in industrial pipeline systems, eccentric valves are widely used in many fields such as petrochemicals, electric power, metallurgy and mining, and urban water supply and drainage. The quality of its performance is directly related to the stable operation of the entire system, the accuracy of fluid control, and the effective use of energy. In these complex and critical application scenarios, the boring quality of the eccentric valve body plays a decisive role. With the continuous deepening of industrial automation, the continuous expansion of production scale, and the increasingly stringent requirements for energy conservation and emission reduction, the industrial system has put forward more stringent requirements on the performance indicators of eccentric valves such as sealing, flow regulation accuracy, and corrosion resistance. The improvement of these performances is highly dependent on the high precision and high quality of the boring processing of the eccentric valve body, which not only requires the aperture size tolerance to be controlled within a very small range, but also has almost stringent standards for the surface roughness, roundness, and cylindricality of the hole wall. Therefore, an eccentric valve body boring device is designed.

[0003] The tools of the existing eccentric valve body boring device wear out quickly in the harsh environment of high temperature and high friction, which greatly shortens the service life of the tools and seriously affects the boring quality, resulting in a high product scrap rate.
