Description

Technical Field

[0001] The utility model relates to the field of household daily necessities, in particular to a device for repairing leaks in water vapor pipelines of chemical plants. Background Art

[0002] In the chemical industry, the safe operation of water vapor pressure pipelines is crucial to the entire production system; however, due to various reasons, such as material aging, mechanical wear, improper installation or operating errors, water vapor pipelines in chemical plants often have leaks; these leaks may not only lead to waste of resources, but more importantly, they may pose a serious threat to production safety and may even cause accidents;

[0003] To solve this problem, the traditional solution usually requires the pipeline to be shut down and isolated in order to repair the leak. However, this treatment method not only requires stopping production, but also may cause economic losses when the system is restarted and shut down, especially in large chemical plants. This loss is particularly significant. Therefore, how to effectively eliminate the leak in the water vapor pipeline without interrupting production has become a technical problem that needs to be solved urgently in the chemical industry.

[0004] Although there have been some attempts to solve this problem through online repair or bypass treatment, these methods often have problems such as complex operation, poor results or limited applicability. For example, some online repair technologies may require complex modifications to the pipeline, increasing the difficulty and cost of operation; while some bypass treatment methods may not be able to completely eliminate the leak, or may only be applicable to specific types of leaks.

[0005] Therefore, it is necessary to provide a new chemical plant water vapor pipeline leak repair device to solve the above technical problems. Utility Model Content

[0031] Prepare the outer tube 2 required for repair, and ensure that the inner diameter of the outer tube 2 is the same as the outer diameter of the pipeline 1 to ensure a tight fit.

[0032] A groove 9 is designed on the outer edge of the outer pipe 2 to facilitate subsequent welding operations with the pipeline 1 .

[0033] Connection between outer tube and pipeline:

[0034] The outer tube 2 is placed on the leaking point of the pipeline 1 , and it is ensured that the connection point 5 is aligned with the special-shaped connection mechanism 8 .

[0035] The bolt 7 is passed through the threaded hole 6 of the connection point 5 and matched with the limiting groove 85 at one end of the second L-shaped connecting rod 84 .

[0036] The bolt 7 is rotated to be tightly connected with the outer tube 2 and the pipeline 1. The rounded corner design at the end of the bolt 7 can reduce the wear on the pipeline 1 during the installation process.
