Description
Technical field
The utility model relates to mounted gas cylinder inspection frock, specifically, relates to a kind of cryogenic insulated cylinder vacuum leak hunting frock.
Background technique
Cryogenic insulated cylinder has storage volume large, and the gas purity stored is higher, Safety performance is also higher than common steel cylinder, developed very fast in recent years, output expanding day, vacuum leak hunting, as the important procedure in cryogenic insulated cylinder production process, is used for checking the sealing of gas cylinder inner-outer tube, to the degree of vacuum of product, thermal insulation property plays vital effect.Existing leak hunting technology adopts simple rubber pad to add carbon steel retainer ring, encases the hole of distributor surrounding, easily has leak point, and adopts threaded pipe to connect, and connection is inconvenient and leak detection speed is slow.
For the problem in correlation technique, at present effective solution is not yet proposed.
Model utility content
The purpose of this utility model is to provide a kind of cryogenic insulated cylinder vacuum leak hunting frock, to overcome currently available technology above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cryogenic insulated cylinder vacuum leak hunting frock, comprise inner bag, described inner bag is provided with support tube, described support tube is provided with distributor, described distributor is provided with sealing frock, described sealing frock comprises sleeve, and one end of described sleeve is provided with socket cover, described socket cover is welded with the fast acting flange of vacuum; The other end of described socket cover is also welded with clamp flange, described clamp flange is outside equipped with loose flange, the outer installment of described clamp flange and described loose flange has chain clasp, is also provided with two O-ring seals in addition between described clamp flange and described loose flange.
Further, described socket cover is also provided with opening, described opening and the fast acting flange of described vacuum connect.
Further, the material of described O-ring seals is fluorine rubber or silicone rubber.
The beneficial effects of the utility model are: by being connected with O-ring seals at clamp flange, and with chain clasp by clamp flange and loose flange fastening, O RunddichtringO is made to compress distortion, and then serve the effect of good airproof performance, and the fast acting flange of vacuum arranged more can play the effect of vacuum monitoring, and the utility model also has the feature that structure simple operations facilitates productivity high in addition.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the cryogenic insulated cylinder vacuum leak hunting tool structure schematic diagram according to the utility model embodiment;
Fig. 2 is the sealing frock structural representation according to the utility model embodiment.
In figure:
1, inner bag; 2, support tube; 3, sealing frock; 4, sleeve; 5, socket cover; 6, the fast acting flange of vacuum; 7, clamp flange; 8, loose flange; 9, chain clasp; 10, O-ring seals; 11, opening, 12, distributor.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of the utility model protection.
As shown in Figure 1, a kind of cryogenic insulated cylinder vacuum leak hunting frock according to embodiment of the present utility model, comprise inner bag 1, described inner bag 1 is provided with support tube 2, described support tube 2 is provided with distributor 12, described distributor 12 is provided with sealing frock 3, described sealing frock 3 comprises sleeve 4, one end of described sleeve 4 is provided with socket cover 5, described socket cover 5 is welded with the fast acting flange 6 of vacuum; The other end of described socket cover 5 is also welded with clamp flange 7, described clamp flange 7 is outside equipped with loose flange 8, the outer installment of described clamp flange 7 and described loose flange 8 has chain clasp 9, is also provided with two O-ring seals 10 in addition between described clamp flange 7 and described loose flange 8.
Further, described socket cover 5 is also provided with opening 11, described opening 11 is communicated with the fast acting flange 6 of described vacuum.
Further, described sleeve 4 and socket cover 5 can arrange positioning step or positioning block.
Further, the material of described O-ring seals 10 is fluorine rubber or silicone rubber.
Further, the workpiece size that the specification of described O RunddichtringO can be hunted leak as required carries out flexible design, and the principle that size is selected follows rod seal form.
Wherein, the fluorine rubber selected or silicone rubber, its vacuum seal performance is better, and stable chemical nature, so its gas permeability of aggregate performance is little, meets frock sealability, due to sealed vacuum so its dimensional fits is even more important.
In sum, by means of technique scheme of the present utility model, by being connected with O-ring seals at clamp flange, and with chain clasp by clamp flange and loose flange fastening, make outside O RunddichtringO compress distortion, and then serve the effect of good airproof performance, and the fast acting flange of vacuum arranged can connect vacuum leak hunting equipment easily, more can play vacuumize and vacuum monitoring effect, the utility model also has the feature that structure simple operations facilitates productivity high in addition.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
