[0002] The bellows compensator is a compensating element used in piping systems. It can compensate for displacement in multiple directions, as well as thermal expansion and contraction of the pipeline, and also has the function of silencing and reducing vibration.

[0003] The structure of the bellows body includes multiple raised sections and recessed sections, which are arranged at intervals. The diameter of the raised section is larger than the diameter of the recessed section. The bellows body adopts a folding structure, which can be stretched along the axis and also allows a small amount of bending. The working principle of the bellows compensator is mainly to use the elastic expansion and contraction function of the recessed section of the bellows to compensate for the axial, angular, lateral and combined displacements of the pipeline caused by thermal deformation, mechanical deformation and various mechanical vibrations.
