Description

Technical Field

[0001] The utility model relates to the field of corrugated compensators, in particular to a fully sealed leak-proof corrugated compensator. Background Art

[0002] A bellows compensator is a device used in piping systems, usually consisting of a bellows and a flange. Its main function is to compensate for length changes in the piping system caused by temperature changes, vibrations or installation errors, and to absorb vibrations and shocks in the piping system.

[0003] The bellows is the core component of the bellows compensator. The bellows has a certain degree of flexibility and elasticity, which can absorb the thermal expansion and contraction caused by temperature changes in the pipeline system. When the temperature of the medium in the pipeline changes, the bellows can expand or contract, thereby reducing the stress on the pipeline system and protecting the stability and safety of the pipeline system.

[0004] Existing bellows compensators are usually used during transportation. During the transportation process of the bellows compensator, support rods and nuts are usually used to fix the bellows between two flanges to ensure that the bellows can be safely fixed on the flange during transportation. The bellows compensator needs to be disassembled after installation, which is more troublesome. Therefore, a fully sealed and leak-proof bellows compensator is proposed to solve the above problem.
