Abstract
The utility model provides a pipeline, which can be bent to be a certain pipeline route according to the demands of the actual working condition, and can absorb the pipeline distortion and the beeline displacement caused by the libration. In the pipeline used for transporting the liquid according to the utility model, the longitudinal section of a pipe wall is in the shape of a beeline and a ripple which are interweaving, and the beeline part of the longitudinal section of the pipe wall has the same thickness with the ripple part of the longitudinal section of the pipe wall. In the pipeline with the structure, the ripple part of the longitudinal section is easy bent to form various angles and avoided the usage of a connecting piece because of the clearance left between wave crests. In addition, because the clearance is left still between the wave crests when the ripple part of the longitudinal section is bent to be a certain angle, the displacement and the distortion caused by the bend under the action of the outside force, and the expansion and the constriction of the pipe can be absorbed.
Description
Technical field
The utility model relates to the pipeline that is used to transport fluid, particularly a kind of flexible pipeline that is used to transport fluid.
Background technique
Pipeline is a kind of use engineering material very widely, is used for transmitting various fluids and gas.Under general working environment, the pipeline cabling is straight line not necessarily, and may be made up of the different pipeline of some directions, therefore need couple together by link between the different segment pipes.For example different but need the pipeline that links to each other for two sections angles, can adopt an elbow to connect, these elbow two ends offer screw thread, and the screw thread of coupling is also offered in the end of pipeline, therefore can couple together by worm structure.But this mode is cumbersome, and owing to be hard connection, so when vibration is big, can't absorbs relative displacement or distortion between two segment pipes, thereby cause fluid or gas to be revealed from connection part.
Summary of the invention
The purpose of this utility model provides a kind of pipeline, and it can bend to certain pipeline cabling according to the needs of actual working environment, and can absorb pipeline distortion and straight-line displacement that vibration produces.
According to the pipeline that is used for transporting fluid of the present utility model, straight line shape that the tube wall longitudinal profile is arranged alternately and corrugated, and the linearly part of described tube wall longitudinal profile and tube wall longitudinal profile to be undulatory segment thickness identical.
Reasonable is that described pipeline is made by stainless steel.
Reasonablely be, described pipe diameter is between 14～63 millimeters, and pipe thickness is between 0.5～3.0 millimeter, and the tube wall longitudinal profile is undulatory each part and comprises 15～20 crests, and the spacing between the crest is between between 5～12 millimeters.
In the pipeline of said structure, longitudinal profile is undulatory part owing to leave the space between the crest, so be easy to bend to various angles, has avoided the use of link.In addition,, but still there is the space between the crest, so but bending causes under the expansion of extraction duct or contraction and the external force effect displacement and distortion even bend to several angle.
Description of drawings
Fig. 1 is the schematic representation according to pipeline of the present utility model.
Fig. 2 is the enlarged diagram of the local longitudinal profile of pipeline shown in Figure 1.
Fig. 3 partly is in schematic representation under the bent state for pipeline longitudinal profile shown in Figure 1 is corrugated.
Embodiment
Below by accompanying drawing preferred embodiment of the present utility model is described.
Referring to Fig. 1, in according to pipeline 1 of the present utility model, straight line shape that the tube wall longitudinal profile is arranged alternately and corrugated, and the linearly part S of tube wall longitudinal profile and tube wall longitudinal profile to be undulatory part W thickness identical.For a segment pipe, the straight line shape part of alternately arranging and the length of corrugated part and quantity can be determined according to actual conditions, do not give unnecessary details herein.In addition, pipe material also can be selected according to practical application, and still reasonable is to adopt stainless steel to make.
Referring to Fig. 2, this figure is a certain part section enlarged diagram of pipeline shown in Figure 1, and as shown in the figure, corrugated part W comprises a plurality of crest P that replace and trough V, one section corrugated part can comprise 15～20 crests or trough, and the spacing between crest or the trough is between 5～12 millimeters.Because corrugated partly has certain length, so can adapt to actual pipeline cabling by selecting the suitable bending position of corrugated part.In addition, internal diameter of the pipeline d can be between 15～49 millimeters, and pipe thickness t can be between 0.8～1.2 millimeter.
Referring to Fig. 3, this figure is that pipeline longitudinal profile shown in Figure 1 is corrugated and partly is in schematic representation under the bent state.When bending, upper half part around the pipe bending place extends and lower half portion contraction, as shown in the figure, because the crest of corrugated part and the existence of trough, so when crooked, upper half part adapts to this extension by broadening of crest and trough, and lower half portion adapts to this compression by narrowing down of crest and trough.In like manner, even when pipe bending is angled, as long as the surplus that crest and trough still have broadening or narrow down, but displacement and distortion that just bending causes under the expansion of extraction duct or contraction and the external force effect.It is worthy of note that corrugated partly is bent to 90 degree in Fig. 3, but in fact also can bend to other various angles.
Claims (3)
