a compensator

Abstract

The invention belongs to the technical field of pipeline compensation devices, and particularly relates to a compensator. The compensator comprises an outer cylinder, an inner cylinder, a sealing unitand a fastening unit; the inner cylinder is arranged on the inner side wall of the outer cylinder through the fastening unit, and a first sliding groove is formed in the outer side wall of a shoulderpart of the inner cylinder; a second sliding groove is formed in the outer side wall of a shoulder part of the outer cylinder; the fastening unit comprises bolts, a first fastening block and a secondfastening block; the first fastening block and the second fastening block are connected through the bolts, and a first sliding block is arranged on the first fastening block; the first sliding blockis arranged in the first sliding groove; a second sliding block is arranged on the second fastening block; the second sliding block is arranged in the second sliding groove; a gap is formed between the outer side wall of the inner cylinder and the inner side wall of the outer cylinder; the sealing unit is arranged in the gap, and comprises an air bag and a sealing filler; and the compensation of the inner cylinder and the outer cylinder in the rotating direction is realized through the cooperation among the outer cylinder, the inner cylinder, the sealing unit and the fastening unit.

Description

technical field [0001] The invention belongs to the technical field of pipeline compensation devices, in particular to a compensator. Background technique [0002] The compensator is also called an expansion joint, or an expansion joint; it consists of a bellows (an elastic element) that constitutes its main body of work, and accessories such as end pipes, brackets, flanges, and conduits; it belongs to a compensating element; it is used to work The effective expansion and contraction of the main bellows can absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate for the axial, lateral and angular displacements of pipelines, conduits, and containers. It can also be used for noise reduction and vibration reduction; it is widely used in modern industry. In terms of heating, in order to prevent the deformation or damage of the pipeline due to thermal elongation or temperature stress when the heating pipe...

Problems solved by technology

[0003] In order to make up for the deficiencies of the prior art and solve the problem that the worn sealing packing is easy to lose, when the sealing packing is lost to a certain extent, it will affect the overall sealing performance of the compensator, and it is easy to cause gas leakage when transporting gas; the present invention proposes a kind of compensator
