Description
Technical field
The utility model relates to pipeline compensator field, in particular to a kind of sealing pipeline compensators.
Background technique
Pipeline compensator is also known as expansion bend or telescopic joint, expansion joint, is mainly used for compensation pipeline and is produced by temperature change
Raw expands with heat and contract with cold.If when temperature change pipeline cannot completely freely expansion or shrinkage, thermal stress will be generated in pipeline.?
This stress must be taken into consideration in pipe design, otherwise it may cause the rupture of pipeline, influence the progress normally produced.As pipe
One important component of road engineering, compensator play an important role in terms of guarantee pipeline for a long time normal operation.
Currently, common pipeline compensator can be divided into metal corrugation compensator, non-metal compensator, sleeve expansion joint,
Several major class such as square-shaped joints.Wherein metal corrugation compensator, non-metal compensator are commonplace in use.But it is existing at present
Some pipeline compensators have certain limitation to the compensation rate of pipeline, and are compensated by the way of single-stage compensation, work as pipeline
It is easy transition when expansion or shrinkage amount is much and stretches or compress single-stage compensating element, expendable shape is caused to compensating element,
Become, when tubular expansion or contraction state disappearance post-compensation element cause acting in opposition, thus pipeline need to be equipped with to pipeline many places and mended
Device is repaid, equipment cost is increased.Therefore a kind of band temperate zone means of press seals pipeline compensator of big Multilevel compensating of compensation rate is designed to ability
There is very much realistic meaning for field technique personnel.
