Description

Disposable gas container with safety device

The present invention relates to a disposable gas container with a safety device, and more particularly to a disposable gas container with a safety device to prevent the explosion by discharging the gas to the outside when the internal pressure of the gas container increases.

In general, disposable gas containers can be used easily and can be seen in many places of life, and there is a risk of safety accidents due to remaining gas because they cannot be completely removed when discarded after use.

When the disposable gas container is heated, the internal temperature increases and the vapor pressure rapidly increases. Disposable gas containers that can not withstand the pressure of the steam there is a risk of explosion and explosion like a bomb.

Therefore, various techniques have been proposed to secure the above-mentioned risks. Republic of Korea Patent Application Publication No. 10-2010-0130549 "Butane gas cylinder with a pressure safety outlet" is a PSV (Pressure Safety Valve) is activated when the pressure of the vessel rises above a predetermined value in the industrial pressure vessel, the fluid in the vessel Is configured to be released to the outside. That is, the technique which has an explosion prevention apparatus is proposed so that an explosion of a container may be prevented in an instant by an increase of pressure.

Referring to FIG. 1 in the above-described prior art, the bottom surface of the butane gas cylinder 1 is shown in three dimensions and a V-shaped groove is formed in the bottom of the gas cylinder in a + shape to burner butane. When the pressure in the gas cylinder rises above a certain value, the bottom surface of the gas cylinder is pushed out of pressure and convex outward. At this time, the portion where the groove 2 is formed is weaker in bending strength than the portion where the groove is not formed, so that the groove portion is bent more. The bent portions meet each other in the center in a + -shape (intersection), and the intersection point (3) of the groove having the weakest bending strength is bent on both sides, so the bottom surface is blown out by pressure and the intersection point (3) is eventually torn off. Therefore, a small hole is created at the intersection point 3. However, such a gas cylinder has a problem in that the safety device is exposed to the outside, causing the gas cylinder to burst by an external impact.

Korean Patent Laid-Open Publication No. 2003-0069742 "Explosion-proof structure of aerosol cans" is heated in a state in which residual gas remains in the gas container, so that when the high pressure is generated in the container, the internal pressure is discharged through a valve, In addition, to prevent the danger, in addition, if the expansion pressure of the gas container is so high that the cutout cannot be handled, the valve can be released from the gas container, preventing explosion when disposing of the gas container to prevent personal injury and fire.
