Description

Bellows compensator with adjustable structure

Technical Field

The utility model relates to the technical field of compensators, in particular to a corrugated pipe compensator with an adjustable structure.

Background

Compensators are also conventionally called expansion joints, or telescopic joints. The device consists of a corrugated pipe (an elastic element) which forms a working main body of the device, and accessories such as an end pipe, a bracket, a flange, a conduit and the like. Expansion joints are a flexible structure provided on the vessel shell or pipe in order to compensate for additional stresses caused by temperature differences and mechanical vibrations. The effective expansion and contraction deformation of the corrugated pipe of the working main body is utilized to absorb the dimensional changes of pipelines, ducts, containers and the like caused by expansion due to heat, contraction due to cold and the like, or compensate the axial, transverse and angular displacement of the pipelines, ducts, containers and the like. The heat-insulating pipe can also be used for noise reduction, vibration reduction and heat supply, and in order to prevent the pipeline from deforming or being damaged due to thermal elongation or temperature stress when the heat-insulating pipe is heated, a compensator needs to be arranged on the pipeline to compensate the thermal elongation of the pipeline, so that the stress of the pipe wall and acting force acting on a valve element or a support structure are reduced. As the expansion joint is used as an elastic compensation element capable of freely stretching, the expansion joint has the advantages of reliable work, good performance, compact structure and the like, and is widely applied to the departments of chemical industry, metallurgy, nuclear energy and the like. The expansion joint used in the container has various forms, and the expansion joint is most widely used in the form of U-shaped expansion joint in terms of the shape of corrugation, and then omega-shaped expansion joint, C-shaped expansion joint and the like are adopted. The expansion joint used on the pipeline is divided into a universal type, a pressure balance type, a hinge type, a universal joint type and the like in terms of structural compensation. The expansion joint refers to a flexible element which can effectively play a role in compensating axial deformation, and the corrugated pipe compensator belongs to one type of compensator.

At present, when the corrugated pipe compensator on the market is used, the corrugated pipe compensator is required to adaptively adjust the self length, in actual use, when the corrugated pipe compensator is subjected to self-adaptive adjustment, nuts and screws outside the corrugated pipe compensator are required to be rotated, so that two sides of the corrugated pipe compensator can be contracted or expanded, and when the corrugated pipe compensator is required to greatly adjust the self length, the nuts are required to be repeatedly rotated, so that the length adjustment of the corrugated pipe compensator is too troublesome.
