Abstract
The utility model discloses a high-pressure gas cylinder, which comprises an inner container (1). A plurality of annular metal rings (2) are arranged on the outer surface of the inner container (1), the spacing distance between each two metal rings (2) is reserved, a glass fiber protection layer (3) is further arranged on the outer surfaces of the metal rings (2), and the cross section of the each metal ring (2) is circular. According to the technical scheme, the metal rings (2) have powerful tensile resistance and the property of the high-pressure gas cylinder is enhanced, so that cracks cannot be generated easily, and even though the cracks are generated, the speed of instable expansion of the cracks is low and burst is avoided, and further severe dangerous accidents can be avoided. By the aid of the design, same design requirement can be achieved without increasing safety factor, and accordingly material consumption can be saved to the greatest extent.
Description
Technical field
The utility model relates to a kind of high-pressure bottle, is specifically related to a kind of gas cylinder that is used for gases such as accumulating hydrogen, carbon dioxide, oxygen.
Background technique
Industrial often greater than the gas cylinder of 8MPa gas cylinder.Gas cylinder belongs to a kind of in the special equipment of defined in " special equipment safety monitor regulations ".Because the pressure of the gas that stores in the gas cylinder is higher, and some stored gas is inflammable, explosive, combustion-supporting or cause suffocating, so gas cylinder can cause serious personal injury accident to take place when storage, transportation or improper use.
Large-scale gas cylinder is the large-scale gas cylinder of CNG especially, the integrally-built no joint container that also all adopts at present alloy seamless steel pipe to form through spinning and quenching with Subsequent tempering, and the tangential stress that its internal surface bears is very big, and that the stress that bear the end is wanted relatively is little many.
In addition, there is the danger of unexpected explosion in this integrally-built no joint container.In case crack, the speed of crackle unstability expansion is very fast, uncontrollable will explosion, can cause very serious risk accident thus.In order to solve the above problems, existing product all adopts the design method that strengthens safety coefficient, causes such gas cylinder to have the shortcoming that deadweight is very big, storage efficiency is lower.
The model utility content
The utility model has overcome the deficiencies in the prior art, provides a kind of in the use amount that guarantees farthest to reduce under the high-intensity condition material, can improve the gas cylinder of entire container Safety performance simultaneously.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of gas cylinder comprises inner bag, and the outer surface of described inner bag is provided with the eyelet of a plurality of annulars, between per two eyelets span is arranged.
In order to realize the utility model better, on the basis of such scheme, make further improvement:
As preferably, also be provided with the glass fibre protective layer on the described eyelet outer surface.
As preferably, the cross section of described eyelet is circular.
Compared with prior art, the beneficial effects of the utility model are:
In the technical solutions of the utility model, the inner bag of gas cylinder is provided with eyelet, and eyelet has very strong stretching resistance, has strengthened the performance of whole gas cylinder.
Thereby gas cylinder can not crack easily, even produced crackle, the speed of crackle unstability expansion can be very not fast yet, explosion can not take place, and avoided the serious risk accident.
By the design, need not to adopt the method that increases safety coefficient just can reach same designing requirement, promptly farthest saved the use of material.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the pairing name of the reference character in the accompanying drawing is called:
The 1-inner bag, 2-eyelet, 3-glass fibre protective layer.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but mode of execution of the present utility model is not limited thereto.
As shown in Figure 1, a kind of gas cylinder, the group of its formation wants parts to comprise:
Inner bag 1, eyelet 2, glass fibre protective layer 3.
The annexation of above-mentioned parts is:
A kind of gas cylinder; comprise inner bag 1, the outer surface of described inner bag 1 is provided with the eyelet 2 of annular, between per two eyelets 2 span is arranged; also be provided with glass fibre protective layer 3 on above-mentioned eyelet 2 outer surfaces, the cross section of above-mentioned eyelet 2 is circular.
In sum, just can realize the utility model preferably.
Claims (3)
1. a gas cylinder comprises inner bag (1), it is characterized in that: the outer surface of described inner bag (1) is provided with the eyelet (2) of a plurality of annulars, between per two eyelets (2) span is arranged.
2. gas cylinder according to claim 1 is characterized in that: also be provided with glass fibre protective layer (3) on described eyelet (2) outer surface.
3. gas cylinder according to claim 1 is characterized in that: the cross section of described eyelet (2) is for circular.
