[0002] Bellows compensator, also commonly known as expansion joint, or telescopic joint, is composed of bellows and end pipes, brackets, flanges, conduits and other accessories that constitute its working body. It is mainly used in various pipelines. It can compensate for the thermal displacement and mechanical deformation of the pipeline and absorb various mechanical vibrations, thereby reducing the deformation stress of the pipeline and increasing the service life of the pipeline. The current bellows compensator is not convenient for buffering the vibration generated when the conveying medium flows through, causing the bellows compensator to shake and affecting its stability. Therefore, a bellows compensator with thermal insulation function is needed.

[0003] The existing bellows compensator is not convenient for buffering the vibration generated when the conveying medium flows through it during use, and the thermal insulation performance of the existing bellows compensator is poor. Utility Model Content
