Description

Technical Field

[0001] The utility model belongs to the technical field of abrasive flow processing equipment, in particular to a device for abrasive flow precision processing of ceramic valves. Background Art

[0002] Ceramic valves are mainly used in industrial fields such as electricity, petroleum, chemical industry, metallurgy, mining, sewage treatment, etc., especially in the face of harsh working conditions such as high wear, strong corrosion, high temperature, high pressure, etc., ceramic valves show their excellent performance and have a super long service life. The performance-price ratio of ceramic valves is far better than other similar metal valves. The use of ceramic valves can greatly reduce the number of valve maintenance and replacement, improve the safety and stability of the operating system of supporting equipment, and save equipment repair costs. Second, it can improve the sealing of industrial piping systems, minimize leakage, and thus protect the environment. Third, the raw materials for manufacturing ceramics are extensive and low-cost. It is precisely because of the "brittleness" and difficulty in processing of ceramics themselves that the precision processing of their inner hole walls is relatively difficult, so abrasive flow polishing machines are used for grinding and polishing.

[0003] Among them, temperature has a greater impact on abrasive flow machining equipment. When the temperature rises, the gap between particles becomes larger, reducing the grinding accuracy. Utility Model Content
