Description

Technical Field

[0001] The utility model relates to the technical field of valve surface treatment, in particular to a thermal spraying device for wear-resistant treatment of valve surfaces. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. 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.

[0003] For example, a thermal spraying device for wear-resistant treatment of the surface of a valve ball is disclosed in the Chinese utility model patent publication number (CN219586162U), which includes a bottom plate, a screw rod 1 and a screw rod 2. A fixed groove 1 is provided at the middle end of the surface of the bottom plate, baffles are fixedly provided on both sides of the top wall of the bottom plate, a moving block 1 is provided at the upper end of the bottom plate, and the moving block 1 is provided with two blocks, an electric push rod is fixedly provided at the top of the moving block 1, a fixed block 2 is provided at the upper end of the electric push rod, a fixed groove 3 is provided on the top surface of the fixed block 2, a rotating device 1 is provided inside the fixed groove 3, a moving block 2 is provided at the upper end of the bottom plate, a rotating device 2 is provided at the upper end of the moving block 2, and a rotating device 1 is provided inside the fixed groove 3.

However, the patent cannot control the valve adjustment angle, resulting in the paint tube only spraying paint on the position of the valve close to the paint tube, and the paint is lighter the farther away from the paint tube, resulting in uneven distribution of paint on the valve surface, affecting practicality.

After the spraying work is completed, the electric push rod 601 is turned on again to move the valve to the interior of the first operating box 3, and then the fan 706 is turned on. The fan 706 draws cold air from the outside into the interior of the first operating box 3, so that the paint on the valve surface is quickly cooled and solidified, thereby improving the efficiency of the valve surface treatment work.
