Description

Technical Field

[0001] The utility model belongs to the field of valve painting, and in particular relates to automatic painting equipment special for valve processing. Background Art

[0002] Valves are control components in fluid delivery systems with functions such as shutoff and regulation. Valves used in fluid control systems come in many varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Valves made of metal materials, except for stainless steel and other materials, must be polished after processing and then painted to prevent rust on the metal material on the valve surface.

Automatic painting adopts clamping and fixing painting. The existing automatic painting device clamps the valve through furniture, resulting in the clamping surface being unable to be painted, requiring secondary touch-up painting. Utility Model Content

[0026] Working principle:

[0027] When in use, first open the sealing plug 3, inject the paint into the oil tank 4 through the paint injection pipe 2, and place the valve between the two limiters 10. When the limiter 10 is in the initial state, the electromagnet 19 is in the energized state, so that the two slides 18 are adsorbed, so that the top shaft 16 pulls the positioning plate 17 to compress the spring 15. At this time, the distance between the two positioning plates 17 is smaller than the inner diameter of the valve pipe, and the gas rod 9 circuit is started. The gas rod 9 starts to push the positioner into the pipe. At this time, the electromagnet 19 circuit is closed, and the electromagnet 19 is separated from the slide 18, and the positioning The plate 17 pops up under the action of the spring 15, thereby limiting and fixing the valve from both sides of the inner wall, without fixing the outer paint surface, thereby ensuring the complete painting of the outer paint surface. After the fixing is completed, the sealing door 6 is closed, and the motor 8 and the oil pump circuit are started. The oil pump sprays the paint in the oil tank 4 through the nozzle 11. The paint distribution pipes 12 and the nozzles 11 are arranged at equal intervals, so that the paint surface remains uniform and stable, thereby improving the painting quality of the valve. The motor 8 drives the gas rod 9 to rotate, and the gas rod 9 drives the limiter 10 to rotate at a uniform speed, which is convenient for uniform painting.
