Abstract

A bidirectional pipeline compensator according to the present disclosure includes a first flange. A compensation layer is fixedly mounted on an inner side of the first sleeve piping. Multiple equidistant return springs are fixedly mounted in the compensation layer to surround an inner wall of the compensation layer. An expansion pad is fixedly mounted at each of two internal ends of the compensation layer. Multiple equidistant threaded holes are fixedly defined in the first flange. Multiple equidistant threaded holes, defined in the first flange located on one side, are each provided with a lock bolt. A lock nut is mounted on the other end of the lock bolt. The compensation layer, return spring, expansion pad, lock bolt and lock nut are used together. When the pipeline expands, it contracts upward under the action of the return spring and the expansion pad, thereby preventing the pipeline from bursting resulting from incapability to expand during expansion, and when the pipeline is cooled to contract, the pipeline contracts with the pipeline closely abutting against the compensation layer, under the action of the return spring. The bidirectional pipeline compensator according to the present disclosure can expand and contract, thereby improving the service life of the pipeline.

Description

BIDIRECTIONAL PIPELINE COMPENSATOR

FIELD

[0001] The present disclosure mainly relates to the technical field of pipeline compensators, and in particular, to a bidirectional pipeline compensator.

BACKGROUND

[0002] Compensator, also known as telescopic appliance, telescopic joint or expansion joint, is mainly used to compensate the thermal expansion and cold contraction of pipeline caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, thermal stress will occur in the pipeline, which may cause the pipeline to crack and hinder normal production. Compensator can compensate deformation or displacement of the pipeline, to prevent the pipeline from cracking due to thermal stress. The current pipeline compensator is prone to damage after expansion and contraction, and the service life thereof will be shortened after a long term of use.
