Description

Outer sleeve type elastically fixed corrugated pipe compensator

Technical Field

The invention relates to the technical field of corrugated pipes, in particular to an outer sleeve type elastically fixed corrugated pipe compensator.

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. Also can be used to fall the damping of making an uproar, on the heat supply, in order to prevent that the heat supply pipeline from rising temperature, arousing pipeline deformation or destruction because thermal extension or temperature stress, need set up the compensator on the pipeline, with the thermal extension of compensation pipeline, application number CN202020006329.X's a jacket formula bellows compensator, though the mode of having solved the knob carries out the fixed clamp to the bellows of butt joint and connects, easily make the bellows have the problem that the extrusion drops to the contact, nevertheless the bellows suit through whole section formula carries out the clamping to the bellows, the bellows receives external force and when acting on easily produces relative displacement with the bellows suit, influence fixed effect, the practicality is not good.
