Description

Technical Field

[0001] The utility model relates to a quickly installed compensator. Background Art

[0002] A compensator, also known as an expansion joint or telescopic joint, is a compensating element consisting of a bellows (the working element) and accessories such as end pipes, brackets, flanges, and conduits. It utilizes the effective expansion and contraction of the bellows to absorb dimensional changes caused by thermal expansion and contraction in pipelines, conduits, and containers, or to compensate for axial, lateral, and angular displacement. It offers advantages such as reliable operation, excellent performance, and a compact structure.

[0003] Existing compensators are usually fixed using connecting flanges during installation. Using connecting flanges to fix the compensator is a very effective connection method. However, during use, since the connecting flanges need to be fixed with multiple bolts and nuts, the implementation process is very cumbersome, and the installation process is time-consuming, labor-intensive, and long.
