Description

Technical Field

[0001] This utility model relates to the field of welding joint technology, and in particular to a torsion-resistant high-purity welding joint. Background Technology

[0002] High-purity welded joints are connectors used for transporting high-purity chemical media. However, in actual use, we have found that once the joint is connected to the pipeline, it can no longer be twisted in the circumferential direction. This structural design makes it susceptible to external forces during actual use. For example, the movement generated during equipment use can cause the joint to twist. In this case, due to the fixed connection method adopted by the joint, it is difficult to absorb the torsional force generated during the installation and use of the pipeline, which can lead to sealing failure or structural damage of the joint due to twisting, affecting the normal operation of the equipment.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] A torsion-resistant high-purity welding joint includes a housing 1. A fixing frame 2 is fixedly installed inside the housing 1. A joint fitting 8 is inserted into the fixing frame 2. A rotating ring 3 located inside the fixing frame 2 is fixedly connected to the surface of the joint fitting 8. An annular limiting groove 4 adapted to the rotating ring 3 is opened inside the fixing frame 2. Four notches 5 are opened on one side of the inner cavity of the annular limiting groove 4. A positioning plate 6 is provided on one side of the fixing frame 2. One side of the positioning plate 6 is inserted into the fixing frame 2 and the notches 5. A fixing plate 7 threadedly installed inside the housing 1 is provided on one side of the positioning plate 6. Both the positioning plate 6 and the fixing plate 7 are sleeved on the outside of the joint fitting 8.

[0023] This utility model adopts a joint design that can prevent torsion. During the connection and use process, the pipeline on the joint can rotate flexibly on the joint. In this way, the joint can effectively absorb the torsional force generated by the pipeline during installation and use, avoid sealing failure or structural damage caused by torsion, thereby ensuring the normal operation of the equipment and providing convenience for users.

[0024] The specific usage process is as follows: First, the connector fitting 8 is rotatably installed inside the outer casing 1 via the fixing bracket 2. The outer casing 1 can be mated to the connector accessory 10 and can also be removed from the connector accessory 10. The outer casing 1 and the connector accessory 10 are connected by threads. Thus, when the end of the connector accessory 10 is installed inside the outer casing 1, the end of the connector accessory 10 will mate with the end of the connector fitting 8, forming a complete pipeline, ensuring the smooth operation of the equipment pipeline. A sealing ring is used to seal the end of the connector accessory 10 and the end of the connector fitting 8, ensuring the airtightness of the equipment pipeline and preventing pipeline leakage, providing convenience for the user's work. The rotating ring 3 is fixed to the connector fitting 8, and the rotating ring 3 can also rotate within the fixing bracket 2. When assembling the outer casing 1 and the connector fitting 8, align the rotating ring 3 on the connector fitting 8 with the fixing bracket 2 and snap the rotating ring 3 into the fixing bracket 2. It should be noted that... Figure 5 It is known that the surface of the rotating ring 3 is provided with multiple protrusions, and one side of the inner cavity of the annular limiting groove 4 on the fixing frame 2 is also provided with multiple notches 5 that are adapted to the protrusions. Therefore, when the rotating ring 3 is inserted, the protrusions must be aligned with the notches 5 to ensure that the rotating ring 3 is smoothly inserted into the annular limiting groove 4. Then the rotating ring 3 can rotate and work in the annular limiting groove 4 along with the connector pipe 8. After the rotating ring 3 is installed, the positioning plate 6 is then snapped onto one side of the fixing frame 2. Figure 6It is known that a protrusion matching the notch 5 is also provided on one side of the positioning plate 6. Therefore, after the positioning plate 6 is installed on the fixing frame 2, the notch 5 can be sealed. At the same time, the other parts of the positioning plate 6 will be tightly attached to the side of the fixing frame 2. This ensures the smoothness and stability of the rotation of the rotating ring 3 in the annular limiting groove 4, and also prevents the rotating ring 3 from detaching from the fixing frame 2, providing convenience for the user's work. After the positioning plate 6 is installed, the fixing plate 7 is installed into the outer shell 1 by means of a threaded connection. It should be noted that the fixing plate 7 is also sleeved on the connector fitting 8. In this way, the positioning plate 6 can be fixed, ensuring the stability and firmness of the installation of the positioning plate 6. The torsion block 9 is fixedly connected to the fixing plate 7. It should be noted that when disassembling the fixing plate 7, the user can use the torsion block 9 to rotate the fixing plate 7. The fixing plate 7 can be installed on the connector fitting. The rotating ring 8 can be configured with a hexagonal nut shape for easy disassembly and assembly. This design facilitates the user's assembly and disassembly work. It's worth noting that pre-installed screw holes are provided on the outer casing 1, the mounting bracket 2, the positioning plate 6, and the mounting plate 7 for inserting mounting bolts. Alternatively, the positioning plate 6 can be fixed to the mounting bracket 2 using bolt tightening, limiting the rotation of the rotating ring 3 and ensuring its stability. This provides users with more flexible options. Therefore, an anti-torsion joint design is adopted. During connection, the pipes on the joint can rotate freely, effectively absorbing the torsional force generated during installation and use. This prevents seal failure or structural damage due to torsion, ensuring normal equipment operation and providing convenience for users.

[0025] A torsion block 9 is fixedly connected to one side of the fixing plate 7, and the torsion block 9 is sleeved on the outside of the joint pipe fitting 8.

[0026] Specifically, the twist block 9 is fixedly connected to the fixing plate 7. It should be noted that when disassembling the fixing plate 7, the user can rotate the fixing plate 7 by rotating the twist block 9. The fixing plate 7 can rotate on the connector fitting 8. The twist block 9 can also be set in the shape of a hexagonal nut to facilitate the user's disassembly and assembly work, providing assistance and convenience for the user's disassembly and assembly work.

[0027] A connector 10 is detachably installed on one side of the outer shell 1. One end of the connector 10 is located inside the outer shell 1 and is connected to the connector tube 8. A sealing ring 12 is embedded in one end of the connector 10. A groove 13 adapted to the sealing ring 12 is opened on the end of the connector tube 8 facing the connector 10.

[0028] Specifically, the fitting 10, sealing ring 12, and groove 13 are designed such that the sealing ring 12 is located at the joint between the fitting 10 and the fitting 8 and is also snapped into the groove 13. This ensures the sealing of the equipment pipeline, prevents pipeline leakage, and provides convenience for users.

[0029] One end of the connector 10 is fitted with a sealing ring 11, which is located at the junction of the outer shell 1 and the connector 10.

[0030] Specifically, the sealing ring 11 is set at the connection between the outer shell 1 and the connector 10. This seals the gap at the connection between the outer shell 1 and the connector 10, thereby improving the sealing performance of the connector and providing assistance and convenience for the user.

[0031] Both the fixing frame 2 and the positioning plate 6 have multiple pre-installed bolt holes 14 on one side.

[0032] Specifically, the pre-installed bolt hole 14 can be used to insert installation bolts, or the positioning plate 6 can be fixedly installed on the fixed frame 2 by bolt fastening, thereby limiting the rotation of the rotating ring 3 and ensuring the stability of the rotation of the rotating ring 3, thus providing users with more and more flexible options for their work.

[0033] Both the outer shell 1 and the fixing plate 7 have multiple pre-installed bolt holes 15 on one side.

[0034] Specifically, the pre-installed bolt hole 2 15 is designed for inserting bolts, which allows the fixing plate 7 to be fixed to the outer casing 1 with bolts. This provides an alternative method for installing the fixing plate 7 and facilitates the user's installation work.

[0035] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
