[0002] As an important fluid control component in the industrial field, the manufacturing process of valves covers multiple key links, among which surface treatment is a crucial step. During the production process of valves, their surfaces are often affected by casting, forging, machining and other processes, resulting in rough surfaces and the presence of impurities or oxides, which not only affects the appearance quality of the valves, but also may pose a potential threat to their performance and service life; therefore, effective treatment of the valve surface, such as removing impurities and improving surface finish, is an important task in the valve manufacturing process.

[0003] In the related art, among the many methods of valve surface treatment, sandblasting technology has been widely used due to its advantages such as high efficiency and environmental protection; however, when performing valve surface treatment, traditional sandblasting equipment usually requires manual adjustment of the position of the valve body according to the sandblasting tube. This operation method is not only inefficient, but also often difficult to accurately control the sandblasting position and angle of the valve body. Due to the limitations of manual operation, the valve surface is often difficult to be sandblasted evenly, and some areas may be over-sandblasted or under-sandblasted, which affects the treatment effect of the valve surface and may also have a potential impact on the overall performance and service life of the valve.
