Description

Technical Field

[0001] This utility model relates to the field of electrical valve processing technology, specifically to a surface treatment device for corrosion-resistant electrical valves. Background Technology

[0002] Electrical valves are an important component of fluid control systems in the power industry. Their main function is to control the flow of media and ensure the safe, stable and efficient operation of the system. Electrical valves play a vital role in the power system. They come in a variety of types, each with its specific uses and characteristics. To ensure the corrosion resistance of electrical valves, their surfaces need to be painted during the production process.

[0003] The "High-Strength Valve Surface Treatment Paint Spraying Equipment" disclosed in application number "202322816700.5" includes a workbench, a protective cover fixedly installed on the top surface of the workbench, a raw material box fixedly installed on the top surface of the protective cover, a first connecting pipe fixedly installed on one side of the raw material box, and a pump body fixedly installed at one end of the first connecting pipe. Through the setting of the clamping mechanism, two sets of clamping blocks are moved to fix and clamp the valve on the mounting plate to prevent the valve from shifting during the spraying. Through the setting of the conveying mechanism, the moving plate is moved to move into the protective cover. The paint in the raw material box enters the branch pipe through the pump body and is finally sprayed out through the nozzle to spray the valve on the mounting plate.

[0004] However, the above method still has the following drawbacks: anti-corrosion coating can be sprayed onto the valve surface through branch pipes and nozzles, but the valve surface is irregular. Spraying paint onto the valve surface from top to bottom can easily create blind spots and make it difficult to ensure the uniformity of the paint spraying, thus reducing the coating quality of the valve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The riser and nozzle can spray anti-corrosion paint onto the surface of the electrical valve. The drive assembly drives the support pipe, which in turn drives the horizontal pipe to rotate. This allows the nozzle to move in a circular motion along the electrical valve, thereby increasing the spraying area, reducing the likelihood of blind spots, and ensuring the uniformity of the anti-corrosion paint application. This improves the coating quality of the electrical valve surface. The rotary joint prevents the torque of the support pipe from being transmitted to the paint input pipe, thus maintaining the smooth rotation of the support pipe.

A support column 707 is fixedly provided in the middle of the top end of the support plate 706. The top end of the support column 707 is fixedly connected to the middle of the horizontal tube 3. The bearing and the support plate 706 can prevent the torque of the horizontal tube 3 from being transmitted to the electrical valve. Under the action of the gravity of the electrical valve, it can be kept in a stationary state, which can prevent it from rotating with the horizontal tube 3.

[0027] In this embodiment, preferably, the drive assembly 15 includes a motor 1501, the output shaft of the motor 1501 is fixedly connected to a worm gear 1502, the worm gear 1502 is meshed with a worm wheel 1504, the middle part of the worm wheel 1504 is fixedly connected to the top of the support tube 2, the worm gear 1502 is rotatably connected to a mounting bracket 1503, the bottom end of the motor 1501 and the bottom end of the mounting bracket 1503 are both fixedly connected to the top end of the bracket 1. The worm gear 1502 is driven by the motor 1501, and the worm gear 1502 can drive the support tube 2 to rotate through the worm wheel 1504, so that the support tube 2 can drive the horizontal tube 3 to rotate smoothly.

[0028] In this embodiment, preferably, a base plate 11 is fixedly provided at the bottom end of the support 1, and a rubber ring 12 is fixedly provided at the bottom end of the base plate 11.

[0029] In this embodiment, preferably, a maintenance port 16 is provided on one side of the protective shell 6, and a protective cover 17 is fixedly installed on one side of the maintenance port 16 by screws. The protective shell 6 and the protective cover 17 can provide protection for the drive component 15. The surface of the protective cover 17 is provided with a plurality of heat dissipation grooves 18, which can dissipate heat from the inside of the protective shell 6, making it less likely for heat to accumulate inside the protective shell 6. A protective net is fixedly provided on the surface of the heat dissipation grooves 18, which can prevent foreign objects from entering the protective shell 6. A pipe groove 14 is provided in the middle of the top of the protective shell 6, and the paint input pipe 9 is inserted and connected to the pipe groove 14.

[0030] In use, first connect the paint inlet pipe 9 to the paint pump, then place the hanging ring 703 of the suspension assembly 7 into the suspension groove 702. The hanging ring 703 can support the hook 705 through the support rod 704. Then, suspend the electrical valve on the hook 705. The hook 705 can support the electrical valve. After the electrical valve is suspended, its surface can be prevented from being blocked, and its surface can be exposed to the outside, which is convenient for spraying activities. Finally, the anti-corrosion paint is introduced into the paint inlet pipe 9 through the paint pump. The paint inlet pipe 9 introduces the paint into the two vertical pipes 4 through the horizontal pipe 3. The vertical pipes 4 and the nozzle 5 can spray the anti-corrosion paint onto the surface of the electrical valve.

[0031] During the painting process, the worker drives the worm gear 1502 through the motor 1501 of the drive assembly 15. The worm gear 1502 drives the support tube 2 to rotate through the worm wheel 1504, which in turn drives the horizontal tube 3 to rotate smoothly. The horizontal tube 3 drives the vertical tube 4 to rotate at a uniform speed, which makes the spray head 5 move in a circle along the electrical valve. This increases the painting range, makes it less likely to produce blind spots, and ensures the uniformity of the anti-corrosion paint spraying.

[0032] When the support tube 2 rotates, the rotary joint 8 can prevent the torque of the support tube 2 from being transmitted to the paint input tube 9, thus maintaining the smooth rotation of the support tube 2. The bearing and support plate 706 can prevent the torque of the horizontal tube 3 from being transmitted to the electrical valve. Under the action of the gravity of the electrical valve, it can be kept in a stationary state, preventing it from rotating with the horizontal tube 3. After the electrical valve is sprayed, the hanging ring 703 is lifted by the support rod 704 and taken out from the suspension groove 702. The electrical valve can be quickly removed without contacting it.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
