Description

Technical Field

[0001] This utility model relates to the field of compensator repair technology, specifically a device for temporary repair of compensators in high-pressure gas pipelines. Background Technology

[0002] In the fields of industrial production and energy transmission, high-pressure gas pipelines serve as crucial infrastructure, undertaking the critical task of gas transmission. High-pressure gas pipeline compensators, as essential components of the pipeline system, are used to absorb deformations caused by factors such as temperature changes and pressure fluctuations, ensuring the safe and stable operation of the pipeline.

[0003] However, in practical applications, high-pressure gas pipeline compensators often leak due to various reasons, threatening the safety and stability of the pipeline system. Existing technologies may lack specialized and efficient temporary repair devices for compensator leaks. Some repair methods may struggle to quickly and accurately locate the leak point, or may fail to ensure a tight fit between the repair component and the leak point during the repair process, resulting in poor repair effectiveness and an inability to effectively stop the leak, thus affecting the normal operation of the entire gas pipeline system. Therefore, those skilled in the art provide a device for temporary repair of high-pressure gas pipeline compensators to address the problems mentioned in the background art. Utility Model Content
