The present invention relates to a rechargeable butane gas cylinder, and more particularly, it is easy to replace the gas valve installed to discharge or fill the gas in the butane gas cylinder, the bracket and the valve housing of the gas valve is a position fixing groove and a positioning protrusion It is firmly fixed without being rotated by to prevent the butane gas filled in the liquefied state inside the body from being discharged to the outside in the liquid state, and by discharging only butane gas vaporized inside the body to the outside for safety accidents. The present invention relates to a rechargeable butane gas cylinder which can be prevented in advance and maintain safety under prolonged use.

In general, as more and more people enjoy leisure activities, they use portable gas burners that are portable and easy to cook outdoors, and easily use gas burners in homes and restaurants. Demand is increasing day by day.

In addition, the butane gas as described above uses a butane gas cylinder filled with a predetermined amount of butane gas, and the butane gas cylinder is disposed of when the butane gas charged inside is exhausted.

However, there is a problem in that butane gas remaining in the gas cylinder is discharged into the air while causing the butane gas cylinder to be discharged into the atmosphere as described above, causing environmental pollution, and costs related to disposal.

In order to solve the above problems, in recent years, a filling butane gas container, which can be reused by filling a new butane gas inside a butane gas container where the butane gas is exhausted, is used.

The conventional butane-type butane gas cylinder is formed in the center of the upper cap 11 of the butane gas cylinder combined with the upper cap 11 and the lower cap on the upper and lower portions of the circular body 10, as shown in FIG. A screw coupling hole 13 is formed in the center of the mouth part 12, and a gas transfer pipe 22 through which the butane gas filled in the body 10 of the butane gas cylinder is transferred to one side of the body 21 is protruded, and the body A male screw portion 23 coupled to the screw coupling hole 13 of the upper cap 11 is formed at the upper outer circumference of the 21, and an internal screw portion 24 is formed at the upper inner side of the body 21. The valve housing 20 and the male screw portion 31 coupled to the female screw portion 24 formed inside the upper portion of the body 21 of the valve housing 20 have a valve 30 formed on the lower outer circumference thereof, and a circular body. (41) A through hole 42 is formed at the center lower portion, and a positioning groove 43 is formed at one side of the upper portion of the body 41 to indent the upper cap 11. Is seated on 12 consists of a bracket 40 which is fixed between the valve housing 20 and valve 30.

When the butane gas cylinder is filled with high pressure butane in the torso 10, butane becomes a liquid at room temperature, and the liquid of butane liquefied in the inside of the torso 10 is vaporized to empty the inside of the torso 10. When the butane gas cylinder is used to fill the space, butane gas vaporized in the body 10 is transferred to the gas transfer pipe 22 of the valve housing 20 and discharged to the outside through the valve 30.

And, when the screw coupling hole 13 formed in the center of the inlet portion 12 of the upper cap 11 and the male screw portion 23 of the valve housing 20 and the female screw formed inside the upper portion of the body of the valve housing When the part 24 and the male screw part 31 formed on the outer circumference of the lower part of the valve 30 are combined, airtightness is prevented so that butane gas filled in the body 10 of the butane gas cylinder does not leak out through the screwing part. In order to retain, adhesives are applied or the seals are wound and bonded.

When the butane gas cylinder is used as described above, the butane gas cylinder is laid on the side, and the upper portion of the bracket 40 fixed between the valve housing 20 and the valve 30 is seated on the upper cap 11 of the butane gas cylinder when installed in the combustion device. Positioning groove 43 formed on one side is used to be mounted to the combustion device to be located at the top.

As described above, the gas transfer pipe 22 protruding from one side of the body 21 of the valve housing 20 inserted into the upper cap 11 of the butane gas cylinder mounted on the combustion device is fixed to the position adjustment groove of the bracket 40. In the same direction as 43, the gas filled in the barrel 10 of the butane gas cylinder is discharged to the outside at a position facing upward.

Butane gas cylinder according to the prior art as described above has a problem in that the valve is released by hand after a long time by applying an adhesive to the screwing portion or wound the seal, but it is impossible to maintain the air tightness of the screwing portion butane gas inside the body There was a problem that leaked to the outside.

Then, when removing the valve from the upper cap of the butane gas cylinder to replace the valve by applying an adhesive to the screwed portion or wound the seal as described above, the indentation portion 12 of the body (10) using an external physical force The valve 30 coupled to the male screw portion 23 of the valve housing 20 coupled to the screw coupling hole 13 formed at the center and the female screw portion 24 formed inside the upper portion of the body 21 of the valve housing 20. ), There was a problem that the male thread part 31 of the c) is damaged and the butane gas cylinder cannot be recycled.

In addition, the conventional butane gas cylinder as described above has a problem that the position of the positioning groove of the bracket and the gas transfer pipe of the valve housing moves in the same direction during the assembly of the body and the valve housing, the valve, the bracket or the gas recharging process.

In addition, even if a small shock from the outside during distribution, but the position of the positioning groove of the bracket and the gas transfer pipe of the valve housing is misaligned or severe, butane gas filled inside the body of the butane gas cylinder leaks to the outside.

As described above, when the butane gas cylinder of the position adjustment groove of the bracket and the gas transfer pipe of the valve housing are not fixed in the same direction is used, the gaseous butane gas in the gaseous state is not released and the liquid is liquefied. There was a problem that the butane gas in the liquid state is discharged to the gas transfer pipe.

In addition, as described above, when the butane gas in the liquid state is discharged to the outside through the valve and burned, the flame that is burned penetrates into the body of the butane gas cylinder, and if there is a problem, the butane gas cylinder may explode, causing a safety accident.

The present invention is to radially form a positioning groove centered on the through hole formed in the lower center of the bracket of the butane gas cylinder in order to solve the above problems, the positioning projection coupled to the positioning groove is formed in the center of the body of the valve housing The purpose of the present invention is to provide a butane gas cylinder through which a radially protruding portion of the upper end of the locking jaw can be radially projected on the screw hole so that the positioning groove of the bracket and the gas transfer pipe formed on one side of the body of the valve housing can be firmly fixed in the same direction. .

In addition, the other purpose of the present invention is the butane gas filled in the liquid state in the liquefied state inside the body of the butane gas cylinder is fixed in the same direction as the gas transfer pipe protruding formed in the body of the valve housing and the positioning groove of the bracket as described above It is to prevent safety accidents by preventing them from being released to the outside in a state.
