Description

Automatic gas cut-off of timer style {An automatic gas cut-off of timer style}

The present invention relates to a timer automatic gas shut-off device, and more specifically, a certain time elapses, the supply of gas is rapidly cut off so that no more gas can be supplied to prevent the occurrence of a safety accident such as an explosion or poisoning by gas. It is about timer with automatic timer gas shutoff device to prevent in advance

Most of the gas accidents are caused by abnormal combustion of unburned gas, and the supply of gas to the gas appliance and the like, the incorrect opening and closing of the valve to stop the gas, and the detachment due to the poor connection of the rubber timer tube to the gas appliance and the like. Fires, incomplete combustion, and the like are the causes, and in order to prevent this, fusecocks, reinforced gas hoses, city gas alarms, and interlocking blocking systems with alarms are generally used.

In addition, safety accidents occur even when the ignition device (gas stove, stove, etc.) has to be used for a long time, which leads to a large accident in the event of a fire caused by an accident caused by human resources.

However, while the above-mentioned risks always come, we cannot escape from the use of gas, but also prepared for them.

Therefore, the present invention has been devised to eliminate the conventional problems as described above, and when a certain time elapses, the gas supply is cut off suddenly to prevent a large gas accident caused by a user's mistake in advance. It is a technical task with the focus on making it possible to use.

In order to achieve the above technical problem, the present invention will be described in detail with reference to the accompanying drawings.

That is, Figure 1 is a cross-sectional view showing a preferred embodiment of the present invention, Figure 2, Figure 3, Figure 4 is an operating state diagram showing a preferred embodiment of the present invention and Figure 5 is the main portion enlarged cross-sectional view of the present invention The detailed configuration and operation of the timer type automatic gas shutoff apparatus will be described.

Timer type gas automatic shut-off device (A) configured on one side of the valve 32 is installed to supply or shut off the gas from the gas supply to the ignition device,

The timer gas automatic shut-off device (A) is configured to form a 'Y' shape of the interior of the passage pipe 30 is fitted with the hose 31 and the ball (BALL, 18) is configured to be in close contact with the edge The outer diameter of the ball 18 is larger than the lower inner diameter of the passage tube.

And the operating rod 16 which is configured to penetrate the upper side of the ball (BALL, 18) and one side of the passage pipe 30 is configured to be connected to a line 17 of a predetermined length, of the operating rod 16 At the end, the elastic subsidiary material 14 having a soft and strong restoring force is integrated. In the above configuration, the string 17 is preferably thin and strong thread or fishing line.

Inside the elastic subsidiary body 14, one side is sealed with a timer tube 10, the inside of the timer tube 10 constitutes a blocking plate 13 to move the working medium (inside the timer tube 10) ( 20 to adjust the amount of movement and to form a diaphragm 11 with a spiral formed on the lower side of the timer tube 10, the blocking plate 13 is configured for finer control, the upper side of the blocking plate 13 is the working medium ( The communication groove 15 is formed so that the 20 is rapidly moved from the bottom of the timer tube 10 to the upper side, and the timer groove 19 is formed at the lower side thereof so that the working medium 20 can be slowly moved. You can select and adjust the desired time interval.

In addition, the working medium 20 moving up and down inside the timer tube 10 preferably uses a heavier mass of mercury. When the working medium 20 is moved to the bottom of the timer tube 10, the center of gravity is reduced. As it is moved to the lower side as shown in Figure 3, the ball (BALL, 18) is to be lowered down the gas supply is suddenly cut off.

When the timer tube 10 connected to the elastic subsidiary body 14 is pulled downward as shown in FIG. 4, the working medium 20 under the timer tube 10 moves to the upper portion of the timer tube 10. At the same time the center of gravity is also moved to the upper portion of the timer tube 10, the ball (BALL, 18) in the passage pipe 30 is raised, the gas supply is made.

The gas supply and shut-off time is made by adjusting the amount of the working medium 20 falling from the upper part of the timer tube 10 to the lower part. The appropriate time can be adjusted using the aperture 11 according to the needs of the user. .

Timer-type automatic gas shut-off device of the present invention having the configuration and action as described above can prevent the accident of large-scale accidents due to the user's mistake in advance as the supply of gas is cut off after a certain time has elapsed. Even if you go out and do other things while on, the supply of gas is automatically shut off, so you can be assured of your safety.
