Abstract

The invention discloses a pipeline capable of depleting internal stress. The pipeline comprises an outer-layer steel pipe, an inner-layer steel pipe and internal stress depleting parts. The inner-layer steel pipe is embedded in the outer-layer steel pipe. The internal stress depleting parts are located in a space formed by the outer-layer steel pipe and the inner-layer steel pipe, the four internal stress depleting parts are located in the same cross section, and the inner-layer steel pipe is fixed in the outer-layer steel pipe through the four internal stress depleting parts. The pipeline capable of depleting the internal stress has the beneficial effects that the pipeline is simple in structure, stress damage during installing can be effectively reduced, internal stress deformation of the pipeline is made to be depleted on the outer layer of the pipeline, and accordingly normal operation of the internal working pipeline is not influenced.

Description

The internal digester tube of a kind of stress

Technical field

The invention belongs to pipeline transportation art, more particularly to the internal digester tube of a kind of stress。

Background technology

The primitive form of duct element deformation has stretching (compression), shearings, torsion and bends totally four kinds, all be can be considered the combination of these four basic deformation by the pipe deformation of various loads。Therefore, the basic deformation form of duct element is to solve the basis of complex stress condition problem。

In Practical Project, seldom having primary structure member to be subjected only to single tension and compression, shearing, torsion or bending load, and be mostly effect while multiple load, namely primary structure member is in complex stress condition more。If now such according to simple tension, experimentally determine its allowable stress, it is necessary to various stress and combination thereof are tested one by one, and this is clearly unpractical。

It is therefore desirable to a kind of pipeline that can automatically digest stress in Pipe installing from its inside。

Summary of the invention

The present invention solves above-mentioned technical problem, it is provided that the internal digester tube of a kind of stress rational in infrastructure, simply compact, scientific and effective, the concrete technical scheme of employing is as follows:

The internal digester tube of a kind of stress, including outer layer pipe, inner layer steel pipe, internal stress consumable part, described inner layer steel pipe is nested in outer layer pipe, internal stress consumable part is in the space of outer layer pipe and inner layer steel pipe composition, in same cross section, there are four internal stress consumable parts, and by these four internal stress consumable parts, inner layer steel pipe is fixed in outer layer pipe。

Described internal stress consumable part is spring。

The invention has the beneficial effects as follows: the internal digester tube simple in construction of this stress, it is possible to the effective stress damage reduced in installing, making the stress deformation of pipe interior be consumed at pipeline outer-layer, thus not affecting the properly functioning of internal work pipeline。

Detailed description of the invention

For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below the specific embodiment of the present invention is described further, but does not limit protection scope of the present invention。

Embodiment 1:

The internal digester tube of a kind of stress, including outer layer pipe 1, inner layer steel pipe 2, internal stress consumable part 3, described inner layer steel pipe 2 is nested in outer layer pipe 1, internal stress consumable part 3 is in the space of outer layer pipe 1 and inner layer steel pipe 2 composition, in same cross section, there are four internal stress consumable parts 3, and by these four internal stress consumable parts 3, inner layer steel pipe 2 is fixed in outer layer pipe 1。

Described internal stress consumable part 3 is spring。

The internal digester tube of stress of the present invention is described already by specific embodiment。Those skilled in the art can use for reference present disclosure and suitably change its structure and realize other purpose corresponding, its relevant change is all without departing from present disclosure, all similar replacements and change will become apparent to those skilled in the art that and be considered as being included within the scope of the present invention。
