Description
One, technical field
The utility model relates to a kind of multi-layer cylinder formula ultrahigh pressure vessel, particularly a kind of ultrahigh pressure vessel of tool thin-walled inner core, specifically the ultrahigh pressure cylindrical vessel of the anti-unstability thin-walled of a kind of tool inner core.
Two, background technique
At manufacture fields such as biology, food, chemical industry, macromolecule, functional material, electronic materials, the application of the ultrahigh pressure vessel of working pressure 〉=100MPa is more and more extensive, the demand that manufactures and designs, particularly craving for the large-scale ultrahigh pressure container that also certainly lead to the different ultrahigh pressure vessel of function and structure.
Ultrahigh pressure vessel often need be used the anti-corrosion ultrastrength material manufacturing of high alloy, and it is expensive.
For the ultrahigh pressure of hundreds of MPas easily, the Integral forge type container is difficult to do greatly.Because surpassing the large forgings of 1400MPa, intensity how need adopt two vacuum smeltings with material, and rare greater than 10 tons vacuum smelting furnace.
Multi-layer combined structure has the easily advantage of making, and the deadweight of each layer cylindrical shell can reduce; If the cylindrical shell of different layers is selected the material of different withstand voltage and anti-corrosion grades, then can greatly reduce cost of material.For example, to the inner/outer tube composite structure, inner core is still used expensive high alloy, high anti-corrosion ultrastrength material manufacturing, and outer layer barrel then can be selected the relatively cheap low-alloy super-strength steel manufacturing of price; And the inner core wall thickness is thinner, and cost of material is lower.
Yet the inner core of multi-layer combined ultrahigh pressure vessel not only need bear huge working inner pressure, and for returning to off working state after pyrocondensation shell type or prefastening structure or the inner core generation plastic deformation, inner core often need bear certain external pressure.
When the ratio K＜1.2(of the external diameter of inner core and internal diameter is considered as thin-walled pressure vessel usually) time, if external pressure surpasses certain less limit value, just unstability may occur, namely occur corrugated cave in collapse flat.Its flat ripple number that collapses is also relevant with the slenderness ratio of cylindrical shell.
Guarantee not unstability of inner core, generally inner core is made thick-walled cylinder (ratio of internal-and external diameter is more than 1.2).But making thick-walled cylinder not only needs to expend a large amount of high-quality steel, also can bring the problem that is difficult for manufacturing and high cost.
How the inner tube wall of ultrahigh pressure vessel can be done thin, unlikely unstability again? engineering circles rather perplexs.
Three, summary of the invention
The utility model aims to provide the ultrahigh pressure cylindrical vessel of the anti-unstability thin-walled of a kind of tool inner core; Expectation is eliminated the unstability inducement by improving the thin-walled inner tube structure.
Abandon the form variations factor, the unstability of thin-walled inner core is normally caused that by plastic deformation and the damage that external pressure causes it very easily occurs in when bearing pretension external pressure or removal working inner pressure.
Thinking of the present utility model is to utilize ripple struction compensation deformation, with the pressure difference between flexible pressure-resistant liquid absorption localized stress and the balance inner/outer tube, thereby makes up novel multi-layer drum type ultrahigh pressure vessel.
The technical solution of the utility model comprises for sake of convenience lower inner core that is called for short of thin-walled inner core 1() and urceolus 2(urceolus include but not limited to 1 layer).Difference with the prior art is to be provided with some ripples 3 at inner core 1, by preventing that ripple from being destroyed by huge external and internal pressure is poor, between inner core and urceolus, leave gap and closed at both ends, between inner/outer tube, formed like this spatia 4 of a sealing, inject during this time high voltage bearing fluid 5 in the chamber, crack 4, this fluid should be non-crystallizable under the working voltage effect, solidify or degrade.When inner core bore high pressure, interior pressure passed to urceolus by the fluid in inner barrel and the spatia.Because ripple is to the release of distortional stress, the inside and outside wall of inner core only has small pressure difference.When interior pressure removal, the pressure of spatia 4 inner fluids compresses by inner core, and main distortion is digested by ripple struction.
The described implication that some ripples 3 is set at inner core 1 be circumferential (the barrel circumferencial direction) of inner tube wall and axially (barrel generatrix direction) at least one direction at least one ripple 3 is set, namely or in circumferential direction at least one ripple 3 is set, at least one ripple 3 perhaps is set in the axial direction, circumferentially ripple as shown in Figure 2, ripple is ring-type, axially ripple as shown in Figure 3, ripple passes through bus.
Preferably on circumferential and axial two directions of inner tube wall, at least one ripple 3 is set respectively.
The ripple of inner tube wall can be processed into the groove type that caves inward, and as shown in Figure 3, also can be processed into outside convex type, and as shown in Figure 4, axially ripple can cave inward or be outwards protruding, and circumferentially ripple is as the same.
The section configuration of ripple can be circular arc, U-shaped, V-arrangement or the shape such as compound, as shown in Figure 5.The formed opening of ripple mainly plays the compensation distortion, and as shown in Figure 6, L1 is static A/F, and A/F is L2 when inner core is subjected to interior compressive strain, and L2＞L1 is compensated the inner core distortion, and stress is absorbed.When interior pressure removal, the withstand voltage liquid that is full of spatia assists ripple to restore to the original state, and both synergy guarantee not unstability of inner core.
The optional self-hydraulic oil of withstand voltage fluid, glycerine, ethylene glycol, castor oil, dioctyl sebacate or its mixture.
The technical program can reduce interior barrel thickness, reduces high alloy material; Improve the inner core Security.For example, the thin-walled inner core is made of High-alloy Ultra-high Strength Steel, and urceolus low-alloy super-strength steel manufacturing is all used the High-alloy Ultra-high Strength Steel manufacturing than inner/outer tube, can reduce equipment cost.The thin-walled inner core also reduces the consumption of high alloy steel than heavy wall inner core; Inner core is made thin-walled in addition, if having wearing and tearing or damage also to be convenient to change.
