Description

Technical Field

[0001] This utility model belongs to the field of valve processing technology, specifically relating to a spraying equipment for anti-corrosion processing of metal valves. Background Technology

[0002] Metal valves come in a wide variety of types, and can be categorized into several types based on their application and structural characteristics, such as gate valves, globe valves, ball valves, butterfly valves, check valves, and pressure reducing valves. These valves are widely used in industrial pipelines to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media. Metal valves play a crucial role, particularly in the petrochemical, power, water treatment, and metallurgical industries. Common metal materials used for the valve body include gray cast iron, ductile iron, ordinary cast steel, and cast copper. These materials possess different physical and chemical properties, making them suitable for various working environments and pressure ratings. During the manufacturing process, metal valves require anti-corrosion spraying to extend their service life. However, current valve spraying equipment has low operating efficiency and a small coating volume per pass. Therefore, the inventor proposes a spraying device for anti-corrosion processing of metal valves. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This specific embodiment is a spraying device for corrosion protection of metal valves, and its structural schematic diagram is shown below. Figure 1 , Figure 4 As shown, the system includes a spray table 1, a spray pipe 2, a mounting rod 12, and a drive box 16. The spray table 1 has a concave structure, and the drive box 16 slides into the spray table 1. The spray pipe 2 is fixedly installed on the inner side of the spray table 1, opposite to the drive box 16. The mounting rod 12 is rotatably mounted on the drive box 16, and multiple sets are arranged at intervals along the drive box 16. The liquid outlet direction of the spray pipe 2 faces the mounting rod 12. The spray pipe 2 sprays out an anti-corrosion liquid, and the spray pipe 2 is connected to an anti-corrosion liquid tank (not shown in the figure).

[0024] Reference Figure 2An adjusting screw 6 is threaded onto the end of the mounting rod 12 furthest from the drive box 16. A movable block 7 is rotatably connected to the end of the adjusting screw 6 that extends into the mounting rod 12. A drive block 8 is fixedly connected to the end of the movable block 7 furthest from the adjusting screw 6. Sliding latches 17 are provided on the upper and lower surfaces of the mounting rod 12. The end of the latch 17 inside the mounting rod 12 has an arc-shaped structure, and the end of the drive block 8 that contacts the mounting rod 12 also has an arc-shaped structure. A connecting block 11 is fixedly connected to the side wall of the latch 17, and a spring 9 is connected to the connecting block 11. A fixing block 10 is fixedly connected to the other end of the spring 9. The fixing blocks 10 and connecting blocks 11 are spaced apart, and the fixing blocks 10 are fixedly connected to the inner wall of the mounting rod 12. Rotate the adjusting screw 6, and the adjusting screw 6 slides toward the inside of the mounting rod 12, causing the moving block 7 to slide. At this time, the driving block 8 moves closer to the locking block 17. When it contacts the locking block 17, it pushes the locking block 17. The locking block 17 slides toward the outside of the mounting rod 12. The locking block 17 fits against the inner wall of the metal valve, and the metal valve is fixed.

[0025] Reference Figure 1 , Figure 3 The drive box 16 has a rotating hole 15 for the mounting rod 12 to be rotatably mounted. A rotary motor 14 is fixedly mounted inside the drive box 16 and is connected to the rotating rod. A fixing post 5 is vertically fixedly mounted on the upper surface of the spray table 1, and a lifting groove is vertically opened inside the fixing post 5. A slider 13 protrudes from the surface of the drive box 16 facing the fixing post 5. The slider 13 slides along the lifting groove, and an internal screw 3 is rotatably mounted inside the lifting groove. The internal screw 3 is threadedly connected to the slider 13. A drive motor 4 is fixed on the upper surface of the fixing post 5 and is connected to the internal screw 3.

[0026] Working principle: In use, first, install the metal valve on the mounting rod 12, inserting the central hole of the metal valve into the mounting rod 12. Then, rotate the adjusting screw 6, causing it to slide inwards towards the mounting rod 12, thus moving the moving block 7. At this time, the driving block 8 moves towards the locking block 17. When it contacts the locking block 17, it pushes the locking block 17, causing it to slide outwards towards the mounting rod 12. The locking block 17 then fits against the inner wall of the metal valve, fixing the metal valve in place. After multiple metal valves are installed on the drive box 16, the drive motor 4 starts, driving... When the inner screw 3 rotates, the slider 13, which is threadedly connected to the inner screw 3, moves down along the fixed column 5, causing the drive platform to enter the interior of the spraying station 1. Then, the spraying pipe 2 sprays out the anti-corrosion liquid. The spraying pipe 2 is connected to the anti-corrosion liquid tank (not shown in the figure). The rotary motor 14 starts, driving the mounting rod 12 to rotate, and then the metal valve starts to rotate and come into contact with the anti-corrosion liquid. After the spraying is completed, the drive box 16 moves up and the adjusting screw 6 rotates in the opposite direction. The drive block 8 gradually moves away from the locking block 17. The spring 9 resets and pulls the locking block 17 toward the interior of the mounting rod 12, so that the metal valve can be removed.
