Abstract
The utility model discloses an integrated sampling steel cylinder which comprises a cylinder body. The cylinder body is integrally formed by cold-drawing and stretching a seamless steel tube; small-diameter cylinder openings with closing-up structures formed by hot spinning have uniform overall thickness and are arranged at the two ends of the cylinder body; and a protection layer is arranged on the inner surface of the cylinder body. In the integrated sampling steel cylinder, the weld joint defects are eliminated and the borne pressure is uniform, thereby providing the safety guarantee for an operator in the sampling, storing and transporting process. Meanwhile, the protection layer arranged on the inner surface of the cylinder body can effectively isolate the mediums from cylinder body base materials, thereby avoiding the potential safety hazards brought by the corrosion of the cylinder body. In addition, in the integrated sampling steel cylinder, the mediums or other trace elements can be effectively prevented from being absorbed by the inner surface of the cylinder body, impurities can not be detained and the purity of samples is ensured finally.
Description
[technical field]
The utility model relates to the bunkerage of a kind of gas or liquid, particularly a kind of sampling steel cylinder that adopts solid drawn pipe to make.
[background technology]
Traditional sampling steel cylinder mainly is welded.This sampling steel cylinder has the twice circumferential weld at least, has defectives such as welding slag, pore, shrinkage porosite, and pressure-bearing property is poor, easily causes bottle to leak; In addition, the inboard unprotect layer of bottle, the bottle mother metal directly exposes in air, easily be corroded, and there is weld seam in the inboard, can't reach smoothly bright and clean, easily is detained medium; Also will carry out multinomial detections such as non-destructive flaw detection after the moulding, potential safety hazard is a lot of.Therefore, welded type sampling steel cylinder can not satisfy the operating needs of Korrosionsmedium, and being replaced by one-shot forming sampling steel cylinder becomes inexorable trend.
A kind of stainless steel jointless sampling gas cylinder has appearred in the recent period on the market.This seamless sampling gas cylinder adopts the [conventional moulding, and no weld seam is than the welded type steel cylinder part that structurally has made marked progress of sampling.But because of forming technique and equipment deviation, solid drawn pipe is easy deformation in spinning process, as the bottle ovalize, so that need further to be processed into circle behind the steel-cylinder forming through mechanical cutting, cause key position thickness such as bottle and the reducing of steel cylinder shoulder irregular, its potential safety hazard even surpass welded type sampling steel cylinder; On the other hand, though this seamless sampling gas cylinder appearance is brighter and cleaner, bottle inside does not have protective cover yet.Therefore, use this series products can not bring safety control to the operator equally.
[utility model content]
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of integral type sampling steel cylinder is provided, this kind steel cylinder does not have weld seam, is difficult for being corroded, and can eliminate steel cylinder in use because the potential safety hazard that weld defect brings.
The purpose of this utility model is achieved in that it comprises bottle, and its improvements are: bottle is one-body molded by cold-drawing seamless tube and stretching, and the two ends of bottle are the path bottleneck that hot spinning forms the closing in structure, and the inside face of bottle is provided with protective cover;
In the above-mentioned integral type sampling steel cylinder, the shoulder reducing place transitions smooth of described bottle;
In the above-mentioned integral type sampling steel cylinder, the wall thickness of described bottle is even;
In the above-mentioned integral type sampling steel cylinder, the wall thickness of described bottle is 3～14mm;
In the above-mentioned integral type sampling steel cylinder, the external diameter of described bottle is 32～159mm;
In the above-mentioned integral type sampling steel cylinder, any surface finish of described protective cover is level and smooth.
The beneficial effects of the utility model are: bottle is an integral structure, has eliminated weld defect, does not damage mother metal, integral thickness is even, shoulder reducing place transitions smooth has been avoided the phenomenon of pressure-bearing unbalance stress, for the operator provides safety control in sampling, storage and transportation; The bottle inside face is provided with effectively contacting of spacer medium and bottle mother metal of protective cover; avoided on the other hand, also having prevented effectively that medium or other micro-elements from being adsorbed by the steel cylinder inside face because of bottle corrodes the potential safety hazard of bringing; and be not detained impurity, finally guaranteed the pure property of sample.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is the schematic appearance of the utility model integral type sampling steel cylinder
Fig. 2 is the inner structure scheme drawing of bottle
Among the figure: 1, bottle; 2, through way valve; 3, angie type valve; 4, stainless steel handle; 5, larynx hoop; 6, electronic tag; 7, protective cover.
[specific embodiment]
As depicted in figs. 1 and 2, integral type sampling steel cylinder of the present utility model mainly improves the bottle 1 of steel cylinder, and the bottle 1 after the improvement is an integral body, and it does not have any soldered through the hot spinning moulding.In the present embodiment, bottle 1 is a base material with the seamless stainless steel container tube, after the drawbench cold-drawn by specialty, stretch and form the agent structure of integrated bottle 1, by later-model hot spinning closing in machine the path bottleneck that the closing in structure is made in reducing is carried out at the two ends of bottle 1 again, and make the base portion of bottle 1 and shoulder reducing place between the bottleneck form the globoidal structure that seamlessly transits, to reach the purpose of not being detained medium.In manufacturing process, do not add any other metal, also do not correct the apparent defect at bottle or bottleneck two ends in the mode of any destructive characteristics.And the whole wall thickness of bottle 1 must be even, the even then pressurized inequality of wall unevenness, and it is thin excessively that then pressure-bearing property is poor, and the blocked up raw MAT'L of then wasting is so according to concrete enforcement, wall thickness guarantees in 3～14mm scope to good.In addition, the size of bottle 1 external diameter directly has influence on the complexity of processing technology, so the external diameter of bottle 1 guarantees in 32～159mm scope.Contact with the bottle mother metal and cause corrosion for fear of the medium of sampling, the bottle 1 inner new mode that adopts carries out anti-corrosion treatment, forms bright and clean level and smooth protective cover 7 at the inside face of bottle 1, not only prevents adsorbing, and can satisfy the user demand of Korrosionsmedium; And steel cylinder is inner level and smooth, is not detained medium, has finally guaranteed the pure property of sample.
When installing and using, be equipped with bottle valve at the two ends of steel cylinder central axial direction, the bottle valve at two ends is respectively through way valve 2 and has the angie type valve 3 of anti-explosion safety device.Be handled easily person's use, also be equipped with a stainless steel handle 4 on bottle 1, its two ends respectively have a larynx hoop 5 fixing, make handle 4 firmly tightly on bottle 1.For implementing the tracking safety management of steel cylinder, the configurable electronic tag 6 of an end of stainless steel handle.
This later-model integral type sampling steel cylinder can be made the product of multiple volume and pressure rating as required, and its adaptive temperature is-40～60 ℃, meets the management expectancy of country to small pressure container fully.
Described above only is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, any retouching that all those of ordinary skill in the art make according to above description, revises or is equal to replacement, all belongs to this novel scope of protecting.
