Abstract

The utility model discloses a disposable mini type gas steel cylinder, which relates to a compressed gas steel cylinder, and consists of a body manufactured by low carbon steel plates and used for holding compressed fluid. The body is integrally stretched and closed up, and consists of a round top upwards forming an opening and a closed cap cover between the round top. The cap cover and the round top zone of the body are fixedly connected together through welding; wherein the wall thickness of the cap cover is far smaller than that of the body; moreover, the cap cover is of a thin layer; the thickness of the thin layer is between 0.15mm and 0.3mm to form a puncturing zone; the puncturing zone is easily penetrated than the other part. The disposable mini type gas steel cylinder has the beneficial effects that the gas steel cylinder not only has small size and light weight, but also can be stored for a long period, can be used for once, is convenient to be carried, can quickly charge or discharge the compressed gas within 0.3s, and is simple and convenient to be operated.

Description

The disposable micro gas cylinder

Technical field

The utility model relates to compressed gas cylinder, has the disposable gas steel cylinder of positioning ring cap specifically.

Background technique

At present, disposable compressed gas cylinder and microcylinder can under high pressure be stored quite a large amount of selection gas, the space so be widely used, the for example emergent inflation of inflatable life jacket, life ring, aviation lifesaving's clothing, fire extinguisher, Motor Vehicle, air gun, safe automobile air bag, EEBD, family expenses breathing apparatus and oxygen water health-care drinking machine etc., however existing gas cylinder is not to be suitable for every kind of application that their use at present very ideally.

The model utility content

The technical problem that the utility model solved is to provide a kind of employing integrally stretching to close up, and the disposable micro gas cylinder of store compressed gas under high pressure.

The technical solution adopted in the utility model is the disposable micro gas cylinder, comprise the main body of holding compressed fluid, the dome that forms behind the integrally stretching of main body top, and the cap that is connected with dome, it is characterized in that: the top area of described dome fuses by sealing between welding manner and the cap, is shaped on positioning ring on the face that the top area of cap and dome is welded.

The wall thickness of described cap is far smaller than the wall thickness of main body, is lamelliform at described cap, and thickness of thin layer is 0.15-0.3mm, forms pierce region, and this pierce region is more prone to penetrate than remaining part.

Can charge into all gases that needs in the described gas cylinder.

The pierce region that the utility model only needs to seal cap is in use broken up, and pressurized gas is discharged.

The beneficial effects of the utility model not only volume are little, and are in light weight, and can long preservation, and disposable use is easy to carry, and charges into or discharge pressurized gas fast in 0.3s, and is easy and simple to handle.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is an A portion enlarged diagram among Fig. 1;

Fig. 3 is the structural representation of cap among Fig. 1.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As depicted in figs. 1 and 2, the disposable micro gas cylinder, the main body of making by low carbon steel plate of holding compressed fluid 1, main body 1 integrally stretching closes up, upwards form the dome 11 of opening, and cap 2 formations of sealing between the dome 11, be fixed together by welding manner between the dome area of cap 2 and main body 1.Wherein the wall thickness of cap 2 is far smaller than the wall thickness of main body 1, and cap 2 is lamelliform, and thickness of thin layer is 0.15-0.3mm, forms pierce region, and this pierce region is more prone to penetrate than other parts.

As shown in Figure 3, be shaped on positioning ring 21 on the face of cap 2 and dome 11 welding, positioning ring 21 just in time is enclosed within the inner wall edge of dome 11.

More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims

1. disposable micro gas cylinder, comprise the main body of holding compressed fluid, the dome that forms behind the integrally stretching of main body top, and the cap that is connected with dome, it is characterized in that: the top area of described dome fuses by sealing between welding manner and the cap, is shaped on positioning ring on the face that the top area of cap and dome is welded.

2. according to the described disposable micro gas cylinder of claim 1, it is characterized in that: the wall thickness of described cap is far smaller than the wall thickness of main body, is lamelliform at described cap, and thickness of thin layer is 0.15-0.3mm.
