Description

Technical Field

[0001] This application relates to the field of valve installation technology, and in particular to an auxiliary device for welding valve sealing rings. Background Technology

[0002] As is well known, valve sealing rings are a composite sealing structure that combines the elasticity of rubber with the strength of metal. The outer layer is made of corrosion-resistant, highly elastic rubber, providing flexible sealing and media adaptability, while the embedded metal skeleton enhances the overall rigidity, withstands high pressure, and prevents the rubber layer from deforming and failing. This type of sealing ring combines the tight fit of rubber with the support of metal, and is suitable for high temperature and high pressure, corrosive media, or vibration conditions. It can effectively solve the problems of easy aging of pure rubber and insufficient elasticity of pure metal seals, and significantly improve the sealing reliability and service life.

[0003] In related technologies, a search revealed that a utility model with patent publication number CN222289223U discloses a support device for welding valve sealing rings, comprising: a support cylinder, the support cylinder being disposed between two sealing rings, the support cylinder being configured as a wedge shape with one side higher than the other according to the distance between the two sealing rings, and a fixing structure for fixing the support cylinder being connected to the lower side of the support cylinder.

[0004] Regarding the aforementioned technologies, the applicant has found that although existing devices can provide uniform support to all parts of the sealing ring surface, thereby reducing the deformation of the sealing ring, making the sealing ring surface flat, reducing the grinding thickness of the sealing ring, increasing the thickness of the sealing ring, and ultimately extending the service life of the valve, the following defects still exist: when welding is performed, heat is generated. When the heat is conducted to the rubber ring part of the valve sealing ring, it will cause the rubber ring to carbonize, harden or deform, resulting in a decrease in sealing performance and insufficient overall practicality.

[0005] Therefore, we propose an auxiliary device for welding valve seals that can isolate the rubber portion of the valve seal during welding. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary device for welding valve sealing rings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An auxiliary device for welding valve sealing rings, comprising:

[0009] Motherboard;

[0010] A sleeve and an adjusting screw are provided. The sleeve is mounted on the main board and is fixedly connected to the main board.

[0018] As a further embodiment of this utility model: the fine-tuning device includes a fixed ring, a fine-tuning threaded rod, and a movable adjustment block. The fixed ring is fixedly welded inside the main board. One end of the fine-tuning threaded rod is rotatably disposed inside the fixed ring. The other end of the fine-tuning threaded rod extends to the outside of the main board through a through hole and is fixedly connected to a horizontal adjustment knob by a key. The movable adjustment block has a threaded groove inside that matches the fine-tuning threaded rod and is threadedly screwed onto the fine-tuning threaded rod through the threaded groove.

During installation, the rubber part of the valve sealing ring is first placed in the heat insulation chamber of the lower cover, while the metal frame extends to the outside through the positioning hole reserved in the lower cover, ensuring that the welding area is fully exposed. The magnetic limiting block is precisely aligned with the limiting groove on the edge of the upper cover, so that the upper and lower covers are tightly closed to form a complete heat insulation barrier. This structure effectively blocks the welding heat conduction path through physical isolation and magnetic locking, ensuring that the temperature of the rubber ring area is always below the safe threshold.

[0045] This auxiliary device for welding valve sealing rings allows for the rapid separation of the upper cover 11 and the lower cover 9 through the coordinated operation of the lifting button 21 and the auxiliary pull ring 22. During installation, the rubber part of the valve sealing ring is first placed in the heat insulation chamber of the lower cover 9, while the metal frame extends to the outside through the positioning hole reserved in the lower cover 9, ensuring that the welding area is fully exposed.

[0049] This is an auxiliary device for welding valve sealing rings. Through the design of this structure, the purpose of preventing the workpiece to be welded from slipping is achieved.

[0050] exist Figure 2 The fine-tuning device includes a fixed ring 15, a fine-tuning threaded rod 16, and a movable adjustment block 17. The fixed ring 15 is fixedly welded inside the main board 1.

The multi-stage hydraulic rod 13 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator.

[0065] The implementation principle of the auxiliary device for welding valve sealing rings in this embodiment is as follows: First, the user quickly separates the upper cover 11 and the lower cover 9 by coordinating the lifting button 21 and the auxiliary pull ring 22. Then, the rubber part of the valve sealing ring is placed in the heat insulation chamber of the lower cover 9, while the metal frame part extends to the outside through the positioning hole reserved in the lower cover 9, ensuring that the welding area is fully exposed. The magnetic limiting block 10 is precisely connected with the limiting groove on the edge of the upper cover 11, so that the upper cover 11 and the lower cover 9 are tightly closed to form a complete heat insulation barrier. Then, the height is adjusted by rotation. Button 4 drives the adjusting screw 3 to rotate synchronously, thereby driving the upper cover 11 and the lower cover 9 to move vertically until they are moved to a suitable welding position. Finally, the workpiece to be welded is placed on the welding platform 19. Then, by rotating the horizontal adjusting knob 18, the fine-tuning threaded rod 16 is driven to rotate synchronously, thereby causing the moving adjusting block 17 to move horizontally, thereby driving the welding platform 19 to move horizontally synchronously to a suitable welding position, so as to weld the workpiece to be welded on the welding platform 19 and the metal skeleton part of the valve sealing ring extending to the outside of the lower cover 9.
