Cryogenic insulated cylinder has the characteristics that safe and reliable, easy to use, charging ratio is high and can fill repeatedly, has been used to substitute tradition Dewar and high pressure steel gas bottle.

Various pipe valves are provided with the end face of insulated gas cylinder, mainly include liquid valve component, feed liquor valve module and emptying Valve module.Original insulated gas cylinder, these valve modules all without what safeguard measure, pipe valve component be easy to knock or, make Into damage, it is therefore necessary to improved.

The content of the invention

The purpose of this utility model is to solve the above problems, and devises a kind of insulated gas cylinder, being capable of pipe valve component.

To achieve the above object, the utility model provides following technical scheme：A kind of insulated gas cylinder, including shell and interior Courage, the inner bag are arranged in the shell, are connected between the inner bag and the shell by support frame, the bottom of the shell Portion is provided with preceding bearing and rear support, is provided with pipe valve component on an end face of the shell, the pipe valve component is arranged on The edge of the end face, the outer ring of the end face edge are provided with baffle plate.There is provided one circle baffle plate after, insulated gas cylinder by To when colliding, it can first bump against on baffle plate, accident occur so as to avoid directly bumping against pipe valve component.

In above-mentioned technical proposal, it is preferred that the pipe valve component includes liquid valve component, feed liquor valve module and emptying valve group Part.Liquid valve component controls the releasing of cryogenic liquid, and feed liquor valve module control cryogenic liquid is put into, and emptying valve module is in interior courage In pressure it is excessive when, for discharging gas, reduce pressure.

In above-mentioned technical proposal, it is preferred that the pipeline is coiled pipe.Coiled pipe further extends low temperature and is delivered to Extraneous distance, reduce heat and scatter and disappear.

In above-mentioned technical proposal, it is preferred that be provided with heat insulation layer between the inner bag and the shell, the heat insulation layer by Sheathing paper and aluminium foil are combined.

In above-mentioned technical proposal, it is preferred that be additionally provided with capacitance level gauge in the inner bag.

The insulated gas cylinder made using the technical solution of the utility model, after a circle baffle plate, in insulated gas cylinder It when being collided, can first bump against on baffle plate, accident occur so as to avoid directly bumping against pipe valve component.

Brief description of the drawings

Fig. 1 is schematic perspective view of the present utility model.

Fig. 2 is sectional view of the utility model along longitudinal direction.

Embodiment

In description of the present utility model, it is also necessary to which explanation, unless otherwise clearly defined and limited, term " are set Put ", " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, Or it is integrally connected；Can be mechanical connection or electrical connection；Can be joined directly together, intermediary can also be passed through It is indirectly connected, can is the connection of two element internals.For the ordinary skill in the art, can be managed with concrete condition Solve concrete meaning of the above-mentioned term in the utility model.

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Referring to Fig. 1 to Fig. 2, insulated gas cylinder, including shell 1 and inner bag 2, the inner bag 2 are arranged in the shell 1, institute State and be connected between inner bag 2 and the shell 1 by support frame 3, the bottom of the shell 1 is provided with preceding bearing 11 and rear support 12, four sides of the shell 1 are arc surface 13, excessive by fillet 14 between adjacent two sides 13, described The diameter of fillet 14 is less than the diameter of the side 13.

Pipe valve component is provided with the end face 15 of the shell 1, the outer ring of the end face 15 is provided with baffle plate 31.Baffle plate Effect is protection pipe valve module, when insulated gas cylinder receives collision, first can be bumped against on baffle plate, so as to avoid directly bumping against pipe valve group There is accident in part.

The pipe valve component includes liquid valve component 16, feed liquor valve module 17 and emptying valve module 18.Liquid valve component control The releasing of cryogenic liquid processed, feed liquor valve module control cryogenic liquid are put into, when pressure of the emptying valve module in interior courage is excessive, For discharging gas, pressure is reduced.

The pipe valve component is arranged on the end face 15 close to the position of the baffle plate 31.The benefit so set is, When further avoiding hitting, hard thing encounters the probability of pipe valve component.

It is connected between the pipe valve component and the inner bag 2 by pipeline 4, the pipeline 4 uses coiled pipe.Coiled pipe enters The distance for extending low temperature and being delivered to the external world of one step, reduces heat and scatters and disappears.

Heat insulation layer 21 is provided between the inner bag 2 and the shell 1, the heat insulation layer 21 is compound by sheathing paper and aluminium foil Form.Capacitance level gauge 22 is provided with the inner bag 2.

Shell of the present utility model adds fillet excessive using the circular arc side of major diameter, its profile and common fuel tank class Seemingly, and in the case of the local identical of occupancy, bigger volume is possessed.

Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., It should be included within the scope of protection of the utility model.
