Abstract
The present invention relates to a kind of prestressed tube structure of application ladder, this structure includes cylinder itself and several prestressed structures, and the prestressed structure successively adds the outer diameter in cylinder according to axial dimension size respectively.Wherein the arrangement of prestressed structure is distributed fully according to cylinder axial dimension institute is loaded.Beneficial effect is: applying different prestressing force by different prestressed structures respectively to the cylinder of different pressure sections, it can make the tube structure of axially different size section, overall radial dimension variation tends to be steady after bearing internal pressurization, the sealing for being conducive to structure in cylinder improves the sealing effect of inner barrel structure.
Description
Technical field
The present invention relates to the prestressed structure fields of cylinder, more particularly, to a kind of super-pressure cylinder.
Background technique
At present in the structure of super-pressure cylinder, especially in the boost process of cylinder, huge pressure bring is close
Envelope pressure difference not only can the both ends sealing structure to cylinder bring huge test, meanwhile, it is loaded after cylinder have it is quite multiple
Miscellaneous stress distribution.The higher requirement that the two kinds of above situations not only propose the sealing structure of cylinder, but also to cylinder
The innovation of body proposes higher standard.
Therefore, a kind of novel, the tube structure loaded with excellent sealing effect occurs just necessary.
Summary of the invention
The present invention be solve it is above-mentioned solves the above problems, be to provide that a kind of structure is excellent, with excellent sealing effect
High pressure barrel.
Technical problem solved by the invention is realized using following technical scheme:
A kind of prestressed tube structure of application ladder, this structure include cylinder itself and several prestressed structures, described pre-
Stress structure successively adds the outer diameter in cylinder according to axial dimension size respectively.Wherein the arrangement of prestressed structure fully according to
Cylinder axial dimension institute is loaded to be distributed.
As optimal technical scheme, multi-layer cylinder is carried out with the fit system of interference fit respectively in high pressure barrel outer diameter
Suit.
As optimal technical scheme, the cylinder of each suit is different respectively in axial dimension.
It is most in the number of plies of loaded biggish the be set with cylinder of axial dimension section of high pressure barrel as optimal technical scheme
's.
The beneficial effects of the present invention are: (1) applies prestressed structure in the case where barrel diameter determines, to cylinder, it can
The effective loaded level for improving cylinder.
(2) apply different prestressed structures to different loaded sections, may make cylinder radial dimension of variation after loaded
It keeps certain, keeps the constant interval of cylinder each section internal diameter steady.
(3) the loaded difficulty for alleviating sealing of the lower radial direction in cylinder both ends is conducive to improve sealing effect.
Detailed description of the invention
Fig. 1 is a kind of present invention: prestressed tube structure isometric view of application screenshot.
Fig. 2 is a kind of present invention: prestressed tube structure diagrammatic cross-section of application screenshot.
Wherein, 1- cylinder, the first prestressed structure of 2-, the second prestressed structure of 3-, 4- third prestressed structure, 5- the 5th
Prestressed structure.
Specific embodiment
In order to make the technological means of this practical invention, acquired expected purpose and function are readily understood by, below with reference to tool
Body diagram, the present invention is further explained.
Referring to shown in Fig. 2, the prestressed tube structure of a kind of application screenshot, mainly by several outside high pressure barrel and cylinder
Layer prestressed structure composition, wherein the several layers prestressed structure is successively sleeved on cylinder external diameter respectively, for each in cylinder
Axial dimension section institute difference loaded, the several layers prestressing force cylinder have differences in axial dimension respectively, and loaded
Biggish place, the prestressed structure number of plies are more.
Above-described embodiment, only an example of invention itself, is not for limiting implementation and power model of the invention
It encloses, all technical solutions identical or equivalent with content described in the claims in the present invention should be included in protection of the present invention
Within the scope of.
Claims (4)
1. a kind of application ladder prestressed tube structure, including cylinder itself is formed with several prestressing force outer rings, feature
It is that several prestressing force outer rings apply certain prestressing force, while each prestressing force outer ring to the structure in respectively circle itself respectively
It is had differences on axial dimension.
2. a kind of prestressed tube structure of application ladder according to claim 1, which is characterized in that inner barrel is each
Load suffered by axial dimension section is different.
3. a kind of prestressed tube structure of application ladder according to claims 1 and 2, which is characterized in that according to difference
The loaded tube structure of size section, applies different prestressed structures to it respectively, and in other words, loaded big position is added pre-
Stress is also big.
4. a kind of according to claim 1, prestressed tube structure of application ladder described in 2,3, which is characterized in that application is answered in advance
Cylinder after power structure tends to be steady in the radial dimension variation of different loaded section of cylinders, and cylinder internal diameter entire change is steady
It is fixed.
