Abstract
The utility model relates to a kind of air cylinder, especially a kind of high-pressure gas cylinder that is used on the gas generator, it comprises bottle and bottle cap, is characterized in, bottle cap be by the curved projection in middle part seal diaphragm and positioning ring is welded, and the eck place of bottle cap and bottle welding connects firmly; Its good seal performance, volume is little, in light weight, is easy to carry, and is safe and reliable, can be widely used in space flight, navigation, fire-fighting, speedily carries out rescue work, field such as lifesaving.
Description
One, technical field
The utility model relates to a kind of air cylinder, especially a kind of high-pressure gas cylinder that is used on the gas generator.
Two, background technique
The high-performance air cylinder that uses on China's gas generator all is to depend on import mostly at present, it costs an arm and a leg, and the production technology of domestic steel cylinder can't resolve the unique high-pressure tightness that requires of high-pressure gas cylinder in this respect, therefore produces the high-pressure gas cylinder that is used on the gas generator at home and still belongs to blank.
Three, the content of model utility
The purpose of this utility model be to provide a kind of cost low, do not have leak, safe and reliable high-pressure gas cylinder.
For achieving the above object, the utility model is achieved in that a kind of high-pressure gas cylinder, comprises bottle and bottle cap, and its special way is, bottle cap be by the curved projection in middle part seal diaphragm and positioning ring is welded, and the eck place of bottle cap and bottle welding connects firmly.
The above-mentioned thickness that seals diaphragm is 0.3-0.5mm.
For the ease of sealing and assurance overall tightness, the air cylinder of big specification is offered a taper air-filled pore in its bottom, be used in bottle, finishing, with conical plug and taper air-filled pore seal welding towards adorning pressurized gas, dash to adorn; The small dimension gas cylinder then directly dashes dress gas from bottleneck, then bottle cap and bottleneck welded seal is got final product.
Bottle of the present utility model adopts the high-quality low carbon steel plate to close up and make through whole punching press, stretching, adopt special process that two-part of bottle cap and bottle cap and bottleneck are welded, make gas cylinder integral body have excellent sealing performance, there is not any leakage, but long preservation, it is little, in light weight to have volume, be easy to carry, advantage such as safe and reliable, can be widely used in space flight, navigation, fire-fighting, speedily carry out rescue work, field such as lifesaving, its price is significantly less than the import gas cylinder, has realized the production domesticization of gas cylinder, has filled up domestic blank.
Four, description of drawings
Fig. 1 is the structural representation of the big specification of the utility model.
Five, embodiment
For understanding the utility model better, it is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, high-pressure gas cylinder described in the utility model is made of bottle 1 and bottle cap 2, bottle 1 adopts the high-quality low carbon steel plate to close up and make through whole punching press, stretching, have taper air-filled pore 5 in the bottom of bottle 1, taper air-filled pore 5 dashes the dress gas that expansion coefficient is big, release rate is fast by conical plug 6 welded seals from taper air-filled pore 5 in bottle; Bottle cap 2 is that the diaphragm 3 of sealing by the curved projection in middle part adopts special welding procedure to weld together with positioning ring 4 to form, the thickness that seals diaphragm 3 is 0.3-0.5mm, a thorn is broken when using with assurance, and the gas in the abrupt release bottle plays due rescue effect; Bottle cap 2 also is to adopt the eck place welding of same welding procedure and bottle 1 to connect firmly.
Above-mentioned high-pressure gas cylinder is installed on the gas generator, has been successfully applied to automotive safety protection field, the gas cylinder that is through with depends on the history of import, and function admirable is safe and reliable.
