Technical Field

[0001] The utility model relates to the technical field of valve production, in particular to a valve spraying device for valve production. Background Art

[0002] The production and processing of valves must go through milling, drilling, grinding, spraying and other processes. The spraying process is mainly to protect the valve, which plays a vital role in the service life of the valve. The spraying process is to spray a layer of paint on the outer surface of the valve to protect the valve through the paint, thereby achieving anti-corrosion and anti-oxidation effects.

[0003] However, the following problems still exist in actual use:

[0004] When spraying existing valves, the valves are directly mounted on hooks, and the valves are sprayed by manually holding a spray gun, and another set of hooks is combined to rotate the valves. In this operation mode, the valves cannot remain stable during the spraying process, resulting in uneven spraying of the valves. At the same time, manual hand-held spraying cannot guarantee the thickness of the spraying, resulting in failure to achieve an ideal spraying effect. Manual spraying is inconvenient to operate and has low spraying efficiency. Utility Model Content

[0013] 1. The valve spraying device for valve production is provided with a rotating positioning mechanism. When positioning the valve to be sprayed, the valve is first sleeved on the outer surface of the two groups of positioning blocks. At this time, the two-way screw is rotated and connected inside the slide groove, and the outer surfaces of both ends of the two-way screw are threadedly connected with sliders, and the positioning block and the slider are fixedly connected, so that the two groups of positioning blocks are tightly fitted on the inner wall of the valve, thereby limiting the position of the valve.
