Summary of the invention
The utility model purpose is, a kind of gas cylinder seal structure is provided, and to solve above-mentioned technical problem point, reaches in light weight, non-corrosive and does not have the practical effect of iron filings.
The technical characterstic of dealing with problems: a kind of gas cylinder seal structure is provided, it is characterized in that, include:
One tank body, this tank body are aluminum alloy tank body, and the opening of this aluminum alloy tank body is provided with a class's platform and a ring flange;
One seal plate is provided with an O-ring cylindrical shell, and it is one-body molded a cirque body, and this seal plate is close on this class's platform of this aluminum alloy tank body by this cirque body; And;
One Teflon leak-proof gasket is set on this cirque body of this seal plate and sealing cylindrical body side face, contracts in this ring flange of this aluminum alloy tank body and seals to this seal plate periphery, is fixed in the leak-proof gasket of this Teflon and this cirque body of this seal plate.
Wherein, the sealing cylindrical body of this seal plate is provided with one and seals face, and this face of sealing is a thin face that seals in order to easily to puncture.
Wherein, this seal plate is a bronze medal seal plate.
Wherein, this seal plate is an aluminium seal plate.
Wherein, this seal plate is a stainless steel seal plate.
The utility model is close to class's platform of this aluminum alloy tank body by the cirque body of this seal plate, on cirque body, reach the leak-proof gasket that the cylindrical body periphery is inserted Teflon again, thereafter confined space has the feeding shaping die, this feeding shaping die is in the feeding process, compressing aluminum alloy tank body ring flange is crispaturaed toward internal strain, and then compacting seals in the seal plate periphery, and closely fixed this Teflon leak-proof gasket and cirque body, reaches in light weight, non-corrosive and do not have the effect of iron filings.
The effect of contrast prior art: gas cylinder seal structure of the present utility model, it utilizes the tank body of aluminum alloy to carry out filling high pressure gas, so in light weight, advantage of good sealing effect that the tank body of aluminum alloy has, and its aluminum alloy and copper material can not get rusty and do not have the problem of iron filings, are beneficial to the use when gas cylinder.
