The present invention configured as described above can provide various advantages such as simple ignition of the gas burner 1 and prevention of accidents due to gas leakage.

That is, according to the present invention, the gas is first supplied to the ignition gas pipe 17 by one operation of the handle 7, and the opening / closing hole 24 of the supply path 15 is placed in an open state in this process. Become. On the other hand, since the gas supply to the supply pipes 3 and 3 'through both the supply nozzle pipes 8 and 8' can be selectively adjusted, the gas supply amount can be freely adjusted and the fuel saving effect can be obtained. Is what you can do.

Further, a safety device is provided in the gas supply unit 22, and when the ignition unit 2 is extinguished, the gas supply unit 22 is automatically set.
The opening / closing hole 24 on the supply path 15 is shut off by the circuit breaker 10, so that an accident due to gas leakage can be prevented.

Hereinafter, the operation method and the effects of the present invention will be described in detail.

FIGS. 3 to 5 are cross-sectional views showing the operation of the present invention, FIGS. 6 to 7 are longitudinal cross-sectional views showing the operation of the gas supply unit 22, and FIGS. It is the longitudinal cross-sectional view shown.

The present invention will first be described with reference to FIGS.
As shown in the figure, the ball body 1 in which the flow holes 131 are formed
The split hole 134 and the split port 133 on the front sphere 13a of the third sphere 3a are not in communication with the air separation paths 12 and 12 ', respectively. In other words, that is, in a state of being opened only to the ignition gas pipe 17 side.

The ball 13 is in the above basic state unless the handle 7 is operated.

In such a basic state, the handle 7
When the gas is supplied to the valve body 6 and rotated, the gas supply is started, and at the same time, the igniter 2 is ignited from the automatic igniter 9, and the gas is supplied through the supply pipes 3 and 3 ′. Will be possible.

For this, first, the handle 7 is pushed in the basic state, and the handle 7 is rotated counterclockwise. When the handle 7 is pushed, the pressure shaft 26 on the handle 7 is pushed as shown in FIGS. 4 and 7, and the pushing shaft 26 inserted into the intermittent hole 25 is opened and closed in the connecting passage 23 of the supply passage 15. Is pressed to open the open / close hole 24.

Then, the space 21 of the handle 7 is completely inserted into the rotation shaft 14 and the spring 20 is in a compressed state. The rear sphere 13b of the ball 13 is connected to the supply path 132 by the supply path 15 and the ignition gas pipe 17.
And a small amount of gas is supplied to the ignition tube 29 of the ignition section 2.

At the same time, the handle 7 presses the pushing knob 9a installed on the igniter 9 above the valve body 6 together with the pushing of the pushing shaft during the pushing process, and the handle 7 from the spark 30 of the ignition part 2 connected to the igniter 9 is pressed. Ensure that spark ignition occurs.

Therefore, first, from the ignition gas pipe 17,
A gas for igniting is supplied onto the igniting section 2. The ignition tube 29 connected to the ignition gas tube 17
At one end, the above-mentioned spark 30 is installed, and when the handle 7 is first pushed and rotated about 45 ° counterclockwise, the opening / closing hole closed by the blocking plate of the circuit breaker 10 as described above. 24 is opened, and gas is supplied to the ignition tube 29 of the ignition gas tube 17 through the supply hole 15. Further, since the pushing knob 9a of the igniter 9 is operated to perform spark ignition from the spark 30, the ignition operation of the gas burner 1 is simplified.

In this state, if the handle 7 is again rotated counterclockwise by about 45 °, the divided opening 133 formed on one side of the front sphere 13a is turned into the air separation path 12 on one side.
The gas is supplied to the supply pipe 3 on one side of the gas burner 1 in communication with the gas burner 1.

At this time, since the gas has already been supplied through the ignition gas pipe 17 and the ignition section 2 is in an ignited state, the gas is supplied to the ignition section 2 only by the supply of the gas through the one side air passage 12. A more vigorous ignition action is performed.

When the handle 7 is again turned in the counterclockwise direction by about 45 °, the divided hole 134 formed on the front sphere 13a of the ball 13 is turned to the other side air passage 12 '. A larger amount of gas is supplied to the ignition section (2) through the two supply pipes 3 and 3 ', so that the heating power of the ignition section 2 is increased.

At this time, the feed port 132 of the rear sphere 13b communicating with the feed path 15 as shown in FIG.
The dividing port 133 and the dividing hole 134 which communicate with each other by the second and the communication holes 131 communicate with each other, and gas is supplied to the supply pipes 3 and 3 'through the two separate air passages 12 and 12'.

Therefore, it is possible to freely adjust the gas supply amount as well as the ignition operation only by a simple operation of the handle 7, whereby a fuel saving effect can be obtained. The benefits of using are guaranteed.

In the above process, the gas is continuously supplied to the ignition gas pipe 17 from the supply port 132 communicating with the supply path 15, and the ignition state of the ignition pipe 29 can be maintained continuously.

The circuit breaker 10 for intermittently opening and closing the opening 24 of the supply path 15 is connected to the heat sensor 31 of the ignition unit 2 and automatically opens and closes when the ignition unit 2 is extinguished during gas supply. It shuts off and interrupts the gas supply.

Hereinafter, this operation will be described in detail.

When the handle 7 is pressed, the blocking plate 10b, which has closed the opening / closing hole 24 with the pushing shaft 26, is separated from the opening / closing hole 24 and is placed in a state of being compressed and supported by the spring 10a. When the ignition unit 2 is in the ignition state, the heat detection sensor 31 installed in the ignition unit 2 detects the heat of the ignition unit 2 when the ignition unit 2 is in the ignition state. As a result, the opening / closing hole 24 is continuously maintained in the open state, so that the supply of gas is continued and the ignition of the ignition unit 2 is maintained.

When the igniter 2 is extinguished, the blocking plate 10b, which has been automatically compressed and elastically supported by the spring 10a, can no longer detect heat by the heat sensor 31. And seal it.

Such a bimetal type automatic gas supply cutoff device is generally used.

As described above, according to the present invention, a normal bimetallic automatic gas supply shutoff device is attached to the valve body 6, and if the ignition unit 2 is extinguished due to outside air or other carelessness during gas supply, it is detected. The sensor 31 detects this and detects the spring 2
Push the blocking plate 10b supported by the compression elasticity to 0, and open and close the opening 2
4 will be sealed. Thereby, the gas supply is interrupted, and further gas supply onto the ignition unit 2 is prevented,
Prevent accidents due to gas leaks.

When the gas burner 1 is extinguished and the supply of gas is cut off, the handle 7 is rotated clockwise to return to the original state, and the ball 13 returns to the original position and the central path 11 When the supply of gas through is cut off, the system is placed in the initial basic state.

[0055]

As described above, according to the present invention, the operation of one handle 7 allows the ignition gas pipe 17 and the branch air path 1 to be operated.
Since the supply of gas in each of the three directions of the supply pipes 3 and 3 'of 2 and 12' is easily and smoothly performed, the convenience in using the gas burner 1 is increased and the gas supply amount can be freely adjusted. become. If the ignition unit 2 extinguishes during the gas supply, the gas supply is automatically shut off, so that a safety-related accident due to gas leakage can be prevented beforehand, and the industrial effect Is high.
