Description

Technical Field

[0001] This utility model relates to the field of spring spraying technology, and belongs to a safety valve spring spraying equipment. Background Technology

[0002] The safety valve spring is a key component of a safety valve. Its main function is to balance the forces acting on the valve disc by compressing the spring, thereby controlling the opening and closing of the safety valve. Safety valve springs are typically helical springs, and their compression can be adjusted by turning the adjusting nut to correct the opening (set) pressure of the safety valve as needed. The working environment of safety valve springs is often filled with media such as water, oil, and steam. Some of these media can have adverse effects on the spring itself, such as corrosion or accelerated rusting. Therefore, the manufacturing process of safety valve springs requires spraying a coating onto the spring surface to prevent rust and corrosion during use, which could affect mechanical operation.

[0003] In existing technologies, conventional safety valve spring spraying equipment typically requires clamps to hold and fix the springs during the spraying process for subsequent spraying. However, these clamps are often complex in structure, cumbersome in operation, and have low processing efficiency. Furthermore, due to design limitations of the spraying components, the spray nozzle often sprays only the outer ring of the spring during the spraying process. This spraying method may result in spraying dead zones on the inner ring of the spring, or a significant difference in coating thickness between the inner and outer rings, thus affecting subsequent use.

[0026] See Figure 3Specifically, the first nozzle 24 has a spray hole array 241 around its periphery, and the second nozzle 25 is annular with a spray hole array 251 on its inner side. The first nozzle 24 is mainly used for spraying the inner ring of the spring, and the second nozzle 25 is mainly used for spraying the outer ring of the spring, to achieve simultaneous spraying of the inner and outer rings and reduce spraying dead zones. The spray hole arrays 241 and 251 can homogenize the paint, making the coating more uniform.

[0027] See Figure 2 Specifically, the electromagnetic fixing platform 31 includes an electromagnet 311, the electromagnet 311 is provided with guide ears 312 on its periphery, and the electromagnet 311 is provided with a positioning cone 313 on its top.

[0028] See Figure 2 Specifically, the lifting assembly 32 includes a drive motor 321, which is located at the bottom of the spraying box 1. The output end of the drive motor 321 extends into the interior of the spraying box 1 and is connected to a threaded screw 322 via a coupling.

[0029] See Figure 2 Specifically, a guide rod 33 is provided between the spraying box bodies 1, and the guide rod 33 is movably connected to the guide ear 312 through a shaft hole.

[0032] The working principle of this utility model:

[0033] The safety valve spring to be processed is placed on the electromagnetic fixing platform 31. After adjusting the position, the electromagnet 311 is activated to attract and fix the spring. Then, the drive motor 321 and the spray pump 21 are started. The drive motor 321 drives the threaded screw 322 to rotate. The threaded screw 322 drives the threaded cylinder 323 to move upward through the threaded transmission. The spray pump 21 pumps the paint and sends the paint into the feed pipe 22 and into the first spray nozzle 24 and the second spray nozzle 25. The first spray nozzle 24 and the second spray nozzle 25 begin to spray. The first spray nozzle 24 and the second spray nozzle 25 gradually spray the inner and outer rings of the spring from top to bottom until the first spray nozzle 24 and the second spray nozzle 25 are close to the bottom of the spring, and the spring spraying is completed. Afterwards, the spray pump 21 stops, the drive motor 321 reverses, which in turn drives the spring to fall until the spring exits the nozzle 25. The drive motor 321 then stops, and the blower fan 44 and heating wire 45 are started. The blower fan 44 blows airflow toward the heating wire 45. The airflow is heated by the heating wire 45 and blown toward the spring to dry the coating on the surface.
