[0002] The bellows compensator is a compensating element. It utilizes the effective expansion and contraction of the bellows, the working body, to absorb the dimensional changes of pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or to compensate for the axial, lateral and angular displacements of pipelines, ducts, containers, etc. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. However, when the existing bellows compensators are in use, when the bellows compensators are subjected to uneven force, they are prone to deformation and bending, which affects their service life. In addition, the bellows compensators are prone to displacement when flanged with the pipeline, which is not convenient for installation. Therefore, a bellows compensator with a buffer structure is required.
