[0002] Valves are important components for controlling the flow of media on industrial pipelines. They can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. Valves are mainly composed of three parts: valve body, opening and closing mechanism, and valve cover. They are widely used because of their easy installation and good opening and closing, regulation, and throttling effects.
[0003] During the production and processing of valve covers, the valve covers need to be turned or polished. Before turning or polishing, the valve covers need to be clamped and positioned. Due to the wide variety of valve cover models, one type of fixture can usually only be used for one type of valve cover. Each time the valve cover model is changed, the fixture must be replaced synchronously, which affects the production and processing efficiency of the valve cover. The types of valve cover models and the irregularity of their appearance hinder the versatility of the fixture in valve cover processing. Utility Model Content
