Description
Technical field
The utility model relates to piping attachment technical field, is specifically related to a kind of corrugated expansion joint.
Background technique
Expansion joint is also compensator traditionally, or slip joint.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.Expansion joint is the additional stress in order to compensate because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.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.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.
Due to expansion joint as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact structure, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that container adopts, has various ways, with regard to the shape of ripple, applies the most extensive with U-shaped expansion joint, secondly also has Ω shape and C shape etc.And the expansion joint adopted on pipeline is with regard to structure compensation, be divided into again universal, pressure balance type, hinge type and Universal connector hair style etc.
Bellows expansion joint is a kind of expansion joint made with metal bellows.It can stretch along conduit axis direction, also allows expansion joint to bend on a small quantity.In order to prevent from exceeding the compensation rate of permission, being provided with protection pull bar or guard ring at bellows two ends, the two ends pipeline be connected with it arranges guiding trestle.Also have corner-type and horizontal type expansion joint in addition, can be used to the corner distortion and the lateral deformation that compensate pipeline.The advantage of this kind of expansion joint saves space, and save material, be convenient to standardization and batch production, shortcoming is that the life-span is shorter.Bellows expansion joint is generally used on the pipeline that temperature and pressure is not bery high, length is shorter.Along with the raising of bellows production technology level, the application area of this kind of expansion joint expands.At present, bellows expansion joint can be used in the piping of maximum pressure 6.0 MPa.
In the industry pipelines such as oil, chemical industry and smelting, except Corrosion Protection requires, also conventional corrugated expansion joint solves pipeline by the cold and hot flexible compensation of medium and counteracting installation deviation; Also by its ductility connect improve the import and export of blower fan and pump and pipeline room machine vibrate caused by mechanical deterioration.Except general loine pressure is malleation, but also some pipeline upward pressure is negative pressure, and the induced draft fan pipeline of such as air and gas system is generally vacuum lines.Existing corrugated expansion joint generally can tolerate certain malleation or negative pressure, but when pressure is larger, corrugated expansion joint is often easily out of shape, and is sometimes out of shape comparatively large so that is difficult to return to original shape, have impact on performance and the life-span of corrugated expansion joint.
Model utility content
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, corrugated expansion joint reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises corrugated expansion joint body, shaping loop, first adapter, adjusting bolt, first lug, head rod, second connecting rod, rotating shaft, second lug, second adapter, the interior outside of described corrugated expansion joint body is provided with shaping loop, the two ends of corrugated expansion joint body are connected with the first adapter and the second adapter, described first adapter and the second vertical correspondence in adapter periphery are provided with the first lug, first adapter and second takes over that periphery and the position that the first lug staggers are vertical is correspondingly provided with the second lug, adjusting bolt is provided with between second lug, head rod and the second connecting rod is provided with between first lug, connected by rotating shaft between head rod and the second connecting rod.
The utility model is used for strengthening the withstand voltage properties of corrugated expansion joint body by shaping loop, make corrugated expansion joint of the present utility model have good withstand voltage properties, avoid the stressed damage of corrugated expansion joint body by the buffer function of head rod, the second connecting rod, rotating shaft.
After adopting said structure, the utility model beneficial effect is: a kind of corrugated expansion joint described in the utility model has good withstand voltage properties, and can increase the service life when not affecting performance, and it is simple that the utility model has structure, arrange rationally, the advantages such as fabricating cost is low.
