Abstract
The utility model discloses a low-temperature air storage cylinder which comprises a cylinder cover, a cylinder body and a cylinder bottom, wherein the cylinder bottom is welded at the bottom end of the cylinder body; the cylinder cover is fixed at the top end of the cylinder body; the cylinder body is in a double-layer bucket structure; a thermal insulation layer is formed between the double-layer structure of the cylinder body; the cylinder cover is in a double-layer arched structure; a vacuum layer is formed between the double-layer structure of the cylinder cover; an air inlet valve, an air release valve and a cleaning valve are mounted on the cylinder cover; a vacuum air valve is mounted on the cylinder body, and connected with the vacuum layer by an air duct; and the bottom end of the air release valve is connected with an exhaust pipe. The low-temperature air storage cylinder has the characteristics that the smoothness of the air inlet valve and the air release valve during start and stop is ensured, and the vacuum degree of the thermal insulation layer of the cylinder body is ensured.
Description
Technical field
The utility model relates to gas and manufactures field, particularly a kind of air cylinder.
Background technique
In the gas manufacturing, gas is manufactured out can be stored in huge gas holder afterwards, if need to use or transportation, need to first divide in the air cylinder that installs to small volume and easily transportation.In order to guarantee can to store gas as much as possible in air cylinder, the general employing becomes liquid method by gas, is stored in the liquid condition that the gas in air cylinder is high pressure low temperature.Due to the low-temperature condition of needs maintenance gas, air cylinder adopts the double-layer vacuum structure more, but after long-time the use, air cylinder degree of vacuum will descend.And, because the gas temperature of storage is lower, often can cause described suction valve, outlet valve to freeze, bring inconvenience to the use of gas.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of low temperature gas holder.The specific design scheme is:
A kind of low temperature air cylinder, comprise bottle cap, bottle, the bottle end, described bottle back welding is connected to the bottom of described bottle, the top of described bottle is fixed with bottle cap, described bottle is double-deck barrel-like structure, and form thermal insulation layer between the double layer construction of described bottle, described bottle cap is the double arch structure, and form vacuum layer between the double layer construction of described bottle cap, on described bottle cap, suction valve is installed, bleed valve, cleaning valve, the vacuum air valve is installed on described bottle and described vacuum air valve is connected with described vacuum layer by air pipe, the bottom of described bleed valve is connected with outlet pipe.
Described suction valve is low temperature valve.
Described bleed valve is low temperature valve.
Described vacuum air valve embeds in described bottle, and is connected with described thermal insulation layer.
Described bottle inside, the end is bowl structure, and the central authorities of described bottle inside, the end are provided with groove.
The described bottle end is double layer construction, and is filled with thermal insulating material between the double layer construction at the described bottle end.
Described outlet pipe embeds in described groove.
The low temperature air cylinder obtained by above-mentioned design proposal of the present utility model, its beneficial effect is:
Form vacuum layer between the double layer construction of described bottle cap, it is mainly to freeze because the joint of described suction valve, outlet valve and bottle cap outside produces that described suction valve, outlet valve open and close difficulty, described vacuum layer can guarantee can freeze without gas, has ensured that the keying of described suction valve, outlet valve is smooth and easy.
The vacuum air valve is installed on described bottle and described vacuum air valve is connected with described vacuum layer by air pipe, described vacuum air valve embeds in described bottle, and is connected with described thermal insulation layer.Described vacuum air valve can ensure the degree of vacuum in described vacuum layer and thermal insulation layer, improves effect of heat insulation.
The accompanying drawing explanation
Fig. 1 is the structural representation of low temperature air cylinder described in the utility model;
In figure, 1, bottle cap; 2, bottle; 3, the bottle end; 4, thermal insulation layer; 5, vacuum layer; 6, suction valve; 7, bleed valve; 8, cleaning valve; 9, vacuum air valve; 10, outlet pipe; 11, groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural representation of low temperature air cylinder described in the utility model, as shown in Figure 1, a kind of low temperature air cylinder, comprise bottle cap 1, bottle 2, the bottle end 3, the described bottle end 3, be welded in the bottom of described bottle 2, the top of described bottle 2 is fixed with bottle cap 1, described bottle 2 is double-deck barrel-like structure, and form thermal insulation layer 4 between the double layer construction of described bottle 2, described bottle cap 1 is the double arch structure, and form vacuum layer 5 between the double layer construction of described bottle cap 1, on described bottle cap 1, suction valve 6 is installed, bleed valve 7, cleaning valve 8, vacuum air valve 9 and described vacuum air valve 9 are installed on described bottle 2 to be connected with described vacuum layer 5 by air pipe, the bottom of described bleed valve 7 is connected with outlet pipe 10.
Described suction valve 6 is low temperature valve.
Described bleed valve 7 is low temperature valve.
Described vacuum air valve 9 embeds in described bottle 2, and is connected with described thermal insulation layer 4.
