Abstract
The utility model relates to an apply barrel construction of ladder prestressing force, this structure includes barrel itself and a plurality of prestressing force structure, prestressing force structure adds the external diameter at the barrel in proper order according to the axial dimension size respectively. The arrangement of the prestressed structure is completely distributed according to the load borne by the axial dimension of the cylinder. The beneficial effects are that: different prestressing forces are applied to the barrels in different pressure sections through different prestressing structures respectively, so that the barrel structures in different axial dimension sections can be enabled, the whole radial dimension change tends to be stable after internal pressurization is borne, the sealing of the barrel inner structure is facilitated, and the sealing effect of the barrel inner structure is improved.
Description
Technical Field
The utility model relates to the prestressing force structure field of barrel especially relates to an ultrahigh pressure barrel.
Background
At present, in the structure of an ultrahigh pressure cylinder body, particularly in the boosting process of the cylinder body, the sealing pressure difference caused by huge pressure intensity can not only bring huge tests to the sealing structures at the two ends of the cylinder body, but also the loaded cylinder body has quite complex stress distribution. The two situations not only put higher requirements on the sealing structure of the cylinder body, but also put higher standards on the innovation of the cylinder body.
Therefore, a need exists for a new type of loaded cartridge structure having good sealing performance.
Disclosure of Invention
The utility model solves the above problems and provides a high pressure cylinder with excellent structure and good sealing effect.
The utility model provides a technical problem adopt following technical scheme to realize:
the utility model provides an exert barrel structure of ladder prestressing force, this structure includes barrel itself and a plurality of prestressing force structure, prestressing force structure adds the external diameter at the barrel in proper order according to axial dimension size respectively. The arrangement of the prestressed structure is completely distributed according to the load borne by the axial size of the cylinder.
As a preferred technical scheme, the multi-layer cylinder body is sleeved on the outer diameter of the high-pressure cylinder body in an interference fit mode.
As a preferred technical scheme, the cylinder bodies of all the sleeving parts are different in axial size.
As the preferred technical scheme, the number of layers of the cylinder bodies sleeved on the section with larger axial size of the high-pressure cylinder body is the largest.
The utility model has the advantages that: (1) under the condition that the diameter of the cylinder body is determined, a prestress structure is applied to the cylinder body, and the loading level of the cylinder body can be effectively improved.
(2) Different prestress structures are applied to different loaded sections, so that the change of the radial size of the cylinder body after being loaded is kept constant, and the change interval of the inner diameter of each part of the cylinder body is kept stable.
(3) The lower radial load at the two ends of the cylinder body reduces the sealing difficulty and is beneficial to improving the sealing effect.
Drawings
Fig. 1 shows the utility model: an isometric illustration of a barrel structure pre-stressed with a screenshot.
Fig. 2 shows the utility model: a cross-sectional schematic diagram of a cylinder structure applying screenshot prestress.
The device comprises a cylinder body 1, a first prestress structure 2, a second prestress structure 3, a third prestress structure 4 and a fifth prestress structure 5.
Detailed Description
In order to make the technical means implemented by the present invention, the intended purpose and functions obtained by the present invention can be easily understood, the present invention will be further described with reference to the following detailed drawings.
Referring to fig. 2, a cylinder structure for applying screenshot prestress mainly comprises a high-pressure cylinder and a plurality of layers of prestress structures outside the cylinder, wherein the plurality of layers of prestress structures are respectively sleeved on the outer diameter of the cylinder in sequence, the plurality of layers of prestress cylinders respectively have difference in axial size aiming at different loads borne by each axial size section in the cylinder, and the number of layers of prestress structures is larger in a place with larger load.
The above-mentioned embodiment is only an example of the present invention, and is not intended to limit the scope of the present invention, and all technical solutions that are the same as or equivalent to the content of the claims of the present invention should be included in the protection scope of the present invention.
Claims (4)
1. A cylinder structure applying step prestress comprises a cylinder body and a plurality of prestress outer rings, and is characterized in that the plurality of prestress outer rings respectively apply certain prestress on structures in the respective prestress outer rings, and the prestress outer rings have difference in axial size.
2. The stepped prestressed tubular construction of claim 1 wherein the axial dimension sections of the interior of the tubular body are subjected to different loads.
3. A stepped prestressed tubular structure according to claim 1 or 2, wherein different prestressing structures are respectively applied to the tubular structures loaded with different size sections, in other words, the prestressing force is large at the position where the loading is large.
