Problems solved by technology

At present, the residual stress of the pipeline during the pipeline installation process causes the compensator to generate a torsional moment, which is prone to deviation, which makes the compensator unstable and the temperature difference changes, so that the compensator has the problem of the length of use

Abstract

The invention discloses a compensator for a low temperature medium pipeline. A torque instability limiter is arranged between a middle pull pipe and each outer side connecting pipe, so that distortion of corrugated pipes and radial instability of the compensator can be avoided; a polyethylene outer protecting pipe is arranged on the outer side of the compensator for the low temperature medium pipeline; heat-insulating layers are arranged between the polyethylene outer protecting pipe and the corrugated pipes, the middle pull pipe and the outer side connecting pipes to prolong the use time; compensating gaskets are arranged among the polyethylene outer protecting pipe, sealing parts and the outer side connecting pipes to ensure the leakproofness of the compensator. The compensator has the advantages of being good in leakproofness and long in use time, and has wide market prospects.

Description

technical field [0001] The invention relates to the field of compensator equipment, in particular to a compensator for low-temperature medium pipelines. Background technique [0002] The compensator is composed of a bellows (an elastic element) that constitutes its working body and accessories such as end pipes, brackets, flanges, and conduits. Belongs to a compensation element. Utilize the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. In heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heated up, it is necessary to install a co...
