Description

Synchronous regulation type expansion joint

Technical Field

The utility model relates to the field of expansion joints, in particular to a synchronous adjusting type expansion joint.

Background

Expansion joints are also conventionally called compensators, or expansion joints. It is composed of bellows (an elastic element) and its working body, end pipe, support, flange and guide pipe. The expansion joint is a flexible structure provided on the vessel shell or pipe in order to compensate for additional stresses due to temperature differences and mechanical vibrations. The effective telescopic deformation of the working body corrugated pipe is utilized to absorb the dimensional change of pipelines, conduits, containers and the like caused by expansion and contraction due to heat and the like or compensate the axial, transverse and angular displacement of the pipelines, the conduits, the containers and the like. The compensator is arranged on the pipeline to compensate the thermal extension of the pipeline, thereby reducing the stress of the pipeline wall and the acting force acting on the valve member or the bracket structure.

The expansion limit of the expansion joint can not be adjusted generally at present, and improvement is needed.
