Abstract
It the utility model is related to a kind of vacuum heat-insulated pipe, including inner and outer tubes, the outer tube is arranged on the outside of inner tube, outer tube is provided with vacuum extraction valve, the outer tube is provided with the first bellows segment, and inner tube is provided with the second bellows segment, and the first bellows segment and the second bellows segment be not on same vertical curve, reinforced sheet is provided with outer tube corner, reinforced sheet is provided with jagged extensible contraction structure.The advantages of the utility model, is embodied in：The utility model solves the problems, such as to expand with heat and contract with cold and pipeline is influenceed by the bellows segment being separately positioned in inner and outer tubes, and the reinforced sheet that the application is set in outer tube corner, on the one hand reinforcement can be played a part of, another convenience, the extensible contraction structure of reinforced sheet can prevent the potential safety hazard of this most easily rupturable position of outer tube corner.
Description
Technical field
It the utility model is related to a kind of pipe-work, and in particular to a kind of vacuum heat-insulated pipe.
Background technology
In laboratory work arrangement field, vacuum heat-insulated pipe is a kind of conventional pipeline, its be used for particular segment roadlock every
Heat transfer, either it is used to prevent heat to scatter and disappear or prevent that medium is influenceed by outside heat in pipe, vacuum heat-insulated pipe is equal
Good effect can be played.
But the shortcomings that existing vacuum heat-insulated pipe, is, during vacuumizing repeatedly, can be formed and expanded with heat and contract with cold
Phenomenon, cause inner tube, outer tracheal rupture, produce potential safety hazard.
Utility model content
The purpose of this utility model is to be directed to deficiency of the prior art, there is provided a kind of vacuum heat-insulated pipe, solve because
Expand with heat and contract with cold the problem of causing pipeline breaking.
To achieve the above object, the utility model discloses following technical scheme：
A kind of vacuum heat-insulated pipe, including inner and outer tubes, the outer tube are arranged on the outside of inner tube, and outer tube is provided with vacuum
Extraction valve, the outer tube are provided with the first bellows segment, and inner tube is provided with the second bellows segment, and the first bellows segment and the second bellows segment be not same
On one vertical curve, reinforced sheet is provided with outer tube corner, reinforced sheet is provided with jagged extensible contraction structure.
Further, support meanss are provided between the outer tube and inner tube.
Further, the support meanss are the support chip set around inner tube.
Further, the support meanss are the conical supports set around inner tube.
A kind of vacuum heat-insulated pipe, has the advantages that disclosed in the utility model：
The utility model solves to expand with heat and contract with cold influence pipeline by the bellows segment being separately positioned in inner and outer tubes
Problem, and the reinforced sheet that the application is set in outer tube corner, it on the one hand can play a part of reinforcement, another convenience, add
The extensible contraction structure of strong piece can prevent the potential safety hazard of this most easily rupturable position of outer tube corner.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment 1,
Fig. 2 is the structural representation of embodiment 2,
Wherein：
1- vacuum extraction valves, the bellows segments of 2- second, 3- support meanss, the bellows segments of 4- first, 5- outer tubes, 6- inner tubes, 7- add
Strong piece.
Embodiment
The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described
Embodiment is only the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Core of the present utility model is to provide a kind of vacuum heat-insulated pipe, solves the pipeline breaking caused by expanding with heat and contract with cold
Problem.
Embodiment 1
See Fig. 1.
A kind of vacuum heat-insulated pipe, including inner tube 6 and outer tube 5, the outer tube 5 are arranged on the outside of inner tube 6, set on outer tube 5
There is vacuum extraction valve 1, the gas that vacuum extraction valve 1 is used to extract between inner tube 6 and outer tube 5 realizes vacuum, and the outer tube 5 is provided with
First bellows segment 4, inner tube 6 are provided with the second bellows segment 2, and the first bellows segment 4 and the second bellows segment 2 can be offset to expand with heat and contract with cold and bring
Pipe deforming even rupture, the first bellows segment 4 and the second bellows segment 2 be not on same vertical curve, to prevent pipeline from excessively becoming
Shape, reinforced sheet 7 is provided with the corner of outer tube 5, reinforced sheet 7 is used for the structural strength for strengthening outer tube corner, and reinforced sheet 7 is provided with
Jagged extensible contraction structure, jagged extensible contraction structure is soft shell fragment, in the process that outer tube 5 expands or tightened up
In, can avoid outer tube excessively stretches drawing, and active force can be offset by broached-tooth design.
In the present embodiment, support meanss 3 are provided between the outer tube 5 and inner tube 6.Support meanss 3 are to be set around inner tube
Support chip.Only play a part of support between support chip and inner and outer pipes, without the space between inner and outer pipes is separated.
Embodiment 2
See Fig. 2.
The present embodiment and the technical scheme in embodiment 1 are basically identical, differ only in, in the present embodiment, the outer tube 5
Support meanss 3 are provided between inner tube 6, support meanss 3 are the conical supports set around inner tube 6.Relative in embodiment 1
Support chip, conical supports this body structures is more firm.
Compared to the content introduced in background technology, the utility model passes through the bellows segment that is separately positioned in inner and outer tubes
Solve the problems, such as to expand with heat and contract with cold influences on pipeline, and the reinforced sheet that the application is set in outer tube corner, on the one hand can play
The effect of reinforcement, another convenience, the extensible contraction structure of reinforced sheet can prevent this most easily rupturable position of outer tube corner
Potential safety hazard.
Described above is only preferred embodiment of the present utility model, rather than its limitations；It should be pointed out that although with reference to upper
Each embodiment is stated the utility model is described in detail, it will be understood by those within the art that, it still can be with
Technical scheme described in the various embodiments described above is modified, or which part or all technical characteristic are equally replaced
Change；And these modifications and replacement, the essence of corresponding technical scheme is departed from various embodiments of the utility model technical scheme
Scope.
