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
The present invention relates to compensator apparatus field, be specifically related to a kind of cryogenic media pipeline compensator.
Background technique
Compensator, by forming the bellows (a kind of elastic element) of its operative body and holding the annexes such as pipe, support, flange, conduit to form.Belong to a kind of compensating element.Utilize effective dilatation of its operative body bellows, to absorb pipeline, conduit, container etc. by reason and the dimensional changes produced such as expanding with heat and contract with cold, or axial, the transverse direction of compensation pipes, conduit, container etc. and angular displacement.Also can be used for noise-and-vibration-reduction.Of many uses in modern industry.In heat supply, when heating up to prevent heat supply pipeline, causing pipe deforming or destruction due to thermal stretching or temperature stress, needing to arrange compensator on pipeline, to compensate the thermal stretching of pipeline, thus the stress reducing tube wall and the active force acted on valve member or supporting structure.At present, in pipe installation process, the effect of pipeline residual stress makes compensator produce torsional moment, easily occurs deviation, the problem of length when making compensator unstability and difference variation make compensator there is use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cryogenic media pipeline compensator, to solve the above-mentioned multinomial defect caused in prior art.
