BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas-

More particularly, the present invention relates to a safety device for preventing gas from escaping from a gas canister, and more particularly, to a safety device for preventing the gas from escaping from the gas can, To prevent the gas cylinder from exploding while the pressure in the gas cylinder is lowered by burning the flame generated in the movable butane combustor to block the firearm in the vicinity of the gas cylinder and to prevent the gas cylinder from exploding will be.

Generally, portable butane burners, which are simple and portable, are often used to cook meat, fish, vegetables, and other foods during outdoor activities such as at home, restaurants and camping.

In the portable butane combustor, a gas cylinder filled with combustible liquefied butane gas, which is supplied to a burner portion of a mobile butane combustor, is used to generate a gas fire when cooking food.

When a gas cylinder filled with a combustible liquefied butane gas is mounted on the regulator of the portable butane combustor and then the ignition lever is rotated, the combustible liquefied butane gas is discharged from the gas cylinder and supplied to the burner unit through the regulator, The discharged combustible liquefied butane gas is ignited by a spark generated in the spark plug.

Here, the gas can be heated by a flame (gas flame) generated in the mobile butane combustor during use of the movable butane flame combustor equipped with the gas cylinder, and a fire due to the use of a flame larger than the specification.

Then, as the flammable butane gas charged in the gas cylinder rapidly expands due to the flame (gas fire) and the flame, the gas cylinder explodes and fragments of the gas cylinder explode as the pressure in the gas cylinder rises, There is a problem that a risk of a safety accident is high, such as an injury can be caused or a burn can be caused by a hot heat.

In recent years, a technique for preventing the explosion of the gas in the gas cylinder has been developed. Among them, a movable butane combustor is heated by a flame (gas fire) generated during use and a firebox, A gas cylinder having the gas discharge structure is provided to discharge the combustible liquefied butane gas in the gas cylinder to the outside to prevent the gas cylinder from exploding when the internal pressure of the gas cylinder increases due to expansion of the gas.

However, when the internal pressure of the conventional gas cylinder is increased to discharge the combustible butane gas to the outside of the gas cylinder, the explosion of the gas cylinder can be prevented. However, the fact that the pressure in the gas cylinder is increased means that the flame around the gas cylinder, (Gas fire) is larger than the flame of the gas fire and the use of the fire bulb is larger than the standard, the flame (gas fire) is diffused more by the gas discharged from the gas cylinder as well as the gas is discharged to the side where the gas is discharged, A fire can be generated by the above flame (gas fire) as well as a fire can be generated by a flame (gas fire) which is diffused and a flame (gas fire) There has been a problem that the risk of safety accidents such as physical damage and personal injury such as a burn injured person is very high.

In order to solve the above problem, the present invention has proposed a safety device for preventing the gas discharge from the gas cylinder (Application No. 10-12013-146968).

Hereinafter, the operational relationship is as follows.

Normally, the pressure in the gas cylinder and the compartment partitioned by the first partition plate remain the same. To this end, the gas is filled in the compartment so as to maintain the same pressure.

Then, the valve opening / closing device is fixed to the lower portion of the gas induction pipe so that the sealing member of the movable member can be positioned at a predetermined distance from the gas flow passage.

In this case, the gas cylinder (10) is heated by the fire extinguisher generated due to use of a flame (gas fire) generated in the external environment, that is, a flame (gas fire) generated in the mobile butane combustor, .

The raised pressure can not be discharged to the outside, so that the rupture part 131 formed on the first partition plate 130 is broken while being ejected through the pressure ejecting port of the second partition plate.

The moving member 170 fixed to the first partition plate 130 moves toward the partition 120 to block the gas flow path 22a so that gas is not discharged to the outside.

One end of the moving member 170 is fixed to the first partition plate 130 through the second partition plate 150 and the other end is connected to the gas passage 22a of the gas induction pipe 22 at a predetermined interval A fixing rod 171 fixed to the first partition plate 130;
An extension rod 173 formed by bending a fixed rod and having a sealing member 175 having an inclined surface which is the same as the inner inclined surface so that the gas flow path 22a is closed at one end and the gas is not discharged to the outside;
A rotation preventing member (not shown) is provided at one end of the fixed rod and moves along the outer side of the gas guiding pipe 22 so as to prevent the sealing member 175 from being inconsistent with the gas flow path 22a when the moving member 170 moves, (177). ≪ / RTI >
The method of claim 5,
The fixing rod 171 is formed in a rectangular shape with the moving path 151 of the second partition plate 150 without the rotation preventing member 177 so that the sealing member 175 is rotated when the moving member 170 moves, Is prevented from being inconsistent with the gas flow path (22a).
