[Prior art]

 Use of general gas includes oxygen, hydrogen, nitrogen, ethylene, etc., which are stored after liquefying the gas at high pressure.All current liquid gases are filled with metal cylinders for storage and storage. This is because they can withstand high pressure when storing liquid gas, but metal cylinders are very heavy, inconvenient for transportation and storage, increase transportation costs, and inconvenient transportation during use.

 Therefore, how to improve the structure design of the high-pressure cylinder, make the structure of the high-pressure cylinder lighter, make it easier to move and transport in the warehouse or during use, and reduce the transportation cost is a bottleneck to be solved by the present invention. It is.

The main object of the present invention is to provide an improved structure of a high-pressure cylinder which greatly reduces the structure of the high-pressure cylinder, makes it easy to move and transport in a warehouse or during use, and greatly reduces the transportation cost.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention creates a cylinder with a reduced bottle mouth from plastic, forms an enlarged conical mouth on the inner wall of the reduced bottle mouth, and forms an annular groove at the end of the bottle mouth with a leak-proof ring. Glue the inside surface of the metal bottle mouth sleeve with an external screw crest at the upper end and glue it to the outer surface of the plastic bottle mouth, and then there is a screw crest on the inner wall at the opening where the opening surface is enlarged Then, tighten the tightening cap with the hollow tightening cone with the inner hole of the sealing surface extending inward and the hollow tightening cone on the outer thread of the bottle mouth sleeve, tightening the tightening cone and the inner wall of the enlarged conical mouth, and further tightening the bottle The entire surface of the body is wrapped with composite carbon fiber to cover the bottle mouth sleeve and the opening of the tightening cap and wrapped around it to reinforce the strength of the bottle and tighten the screw pattern on the inner wall of the tightening cone to the screw pattern step of the adjustment valve. Discharge gas from control valve with gauge .

[Embodiment of the invention]

 Hereinafter, the structure of the present invention and the effects to be achieved will be described in detail with reference to the drawings with reference to the embodiments.

As shown in the three-dimensional exploded view of the present invention in FIG. 1, an annular groove 112 which mainly forms a conical opening 11 1 with an enlarged inner wall of a bottle mouth, and in which a leak stop ring 113 is placed at the end of the bottle mouth 11. A plastic bottle body 10 with a reduced bottle mouth 11 and a metal bottle mouth with an external screw pattern step 21 at the upper end to form an enlarged mouth with an arc similar to the shoulder of the bottle body 10 An adjusting valve having a sleeve 20, an opening having an enlarged opening surface, a screw pattern 41 on the inner wall, a closing hole having a hollow hole 43 extending inward through a middle hole 42, and a pressure gauge 51 having a pressure gauge 51. Consists of 50.

FIG. 2 shows a combination process of the present invention, in which the inner surface of the bottle mouth sleeve 20 is glued and adhered to the outer surface of the plastic bottle body 10 opening 11, Tightening the tightening cap 40 on the outer screw pattern 21 and further wrapping the entire surface of the bottle 10 with the composite carbon fiber 30 to cover the bottle mouth sleeve 20 and the enlarged opening of the tightening cap 40 to cover and enhance the strength of the bottle 10 and increase the liquid gas And can be fixed more firmly to the opening 11 of the bottle body 10 than the bottle mouth sleeve 20 and the tension cap 40, and the pressure gauge 51 is formed by the screw pattern on the inner wall of the bottle body 10 and the tension cone 43. The stepped screw tightening of the adjusting valve 50 having the three-dimensional combination structure shown in FIG. 3 is provided.

FIG. 4 is a combined sectional view of the present invention, in which the bottle mouth 11 of the plastic bottle body 10 is joined and reinforced by a metal bottle mouth sleeve 20, and furthermore, the bottle mouth sleeve 20 is attached from the outside by a tightening cap 40. The outer screw pattern 21 is tightened and expanded from the inside to the conical port 111 with the pressure cone 43, and at the same time, the bottle cap 11 is pressed against the leak-proof ring 113 at the bottom of the pressure cap 40 on the outer circumference of the pressure cone 43. In addition, sufficient tightness and tightness are provided to the bottle opening 11 and the regulating valve 50 which is tightened, and when the gas is introduced from the regulating valve 50, sufficient pressure resistance and leakage can be obtained, and the bottle body 10 is made of composite carbon fiber. With 30 winding reinforcements, it can withstand the high pressure of the stored gas liquid.
