Description

{Low power auto-cut off device for gas valve}

The present invention relates to a gas cooking appliance using LPG or city gas as fuel gas which is continuously supplied through a gas pipe and is used as a fuel gas. When a flame is instantaneously discharged by carelessness in the process of cooking food or a fire occurs, To a non-power source to shut off the supply of gas, thereby preventing a large-scale fire or an explosion accident.

In general, LPG and city gas are used for convenience, but they are very explosive. Therefore, they should pay considerable attention to their use. It is a well-known fact that the death toll has been incurred.

In order to prevent such an accident, an electric gas leak detector for automatically shutting off a gas valve due to the detection of odor and heat when a gas leak or a fire occurs has been developed and used. However, And there was a case where a large accident occurred due to continuous gas leakage because it could not operate when the electric wire was cut off due to a power failure or a fire and could not perform its function.

An object of the present invention is to provide a non-powered gas valve automatic shutoff device having a mechanical structure capable of shutting off gas supply by rotating a handle of a gas valve as a detection by a flame generated in a fire or an explosion accident in order to solve a conventional closed- There is.

In order to accomplish the above object, the present invention provides a non-powered gas valve automatic shutoff device comprising: a gear for rotating an opening / closing handle of a valve installed in front of a gas meter from an open mode to a shutoff mode; And a sensing device for sensing the flame generated in the fire and operating the handle rotation device.

The present invention is characterized in that the gas pipe 1 is connected to the handle 4 'of the gas valve 4 at the side of the casing 3 provided with the mounting device 2 for mounting the gas pipe 1, doing

The lever 5 is accommodated in the rotary shaft 6 inside the casing 3 and the sector gear 7 rotating in the range of 90 degrees with the stopper is accommodated in the electric rotary shaft 6 and the small gear 8 )end

A drive gear 11 integrally attached with a ratchet gear 10 is sequentially engaged with a large gear 9 integral with the small gear 8 and the drive gear 11 and the ratchet gear 10 are fixed A ratchet wheel 10 that rotates a spring 13 with a rotation of a drive shaft 12 by a handle 23 is wound on a spring 13 that imparts a rotational power to a drive shaft 12, A handle rotation device A is connected to a tension spring 15 whose one end is fixed to the inner wall surface of the casing 3 so that the handle rotation device 30 is rotatably supported by the bevel- And a flexible tube having one end fixed to the outer wall surface of the casing 3 so as to stop in a state where the cable is pulled out completely The tip end supporting iron plate 18 of the base plate 17 is connected to the sensing portion 20 and the ratchet striking portion 21 joined with the lead alloy 19 which melts at a predetermined temperature. A binary sensing device (B) consists of coupling.

A manual button 22 for manually rotating the ratchet 30 is provided on one side of the casing 3 so as to protrude out of the casing 3. [

In the figure, reference numeral 24 denotes a stopper, 25 denotes a gas stove, and 26 denotes a gas meter.

The present invention detects a flame during a fire and an explosion due to gas leakage or carelessness during a gas stove when it is used, and mechanically cuts off the gas valve by a non-power source, thereby preventing a large accident and personal injury, There are many excellent effects such as that operation is sure and there is little trouble because there is no.

Fig. 2 is a plan view of the inner plan of the present invention
Figure 3 is a schematic view of the internal structure of the valve with the valve open;
4 is a schematic view of the valve with the valve closed;
Fig. 5 is an example of an installation state of the present invention

When the flame is suddenly emitted from the gas stove 25, the sensing part 20 of the sensing device B installed on the flame is heated by the flame and the lead alloy 19 having a very low melting point melts first, Since the connecting steel plate 16 and the supporting steel plate 18 of the flexible tube 17 are separated from each other, the cable 40 having the tensioning force of the tension spring 15 is instantaneously pulled back into the casing 3, The ratchet striking portion 21 fixed to the ratchet gear 40 hits the ratchet 30 and seesaws the rotation shaft 6 as a starting point so that the control force of the ratchet gear 10 is lost. When the control force of the ratchet gear 10 is released, the ratchet gear 10 is instantaneously rotated by the releasing force of the spring 13 to rotate the driving gear 11 and then the large gear 9 and the small gear 8 And the fan-shaped gear 7 are sequentially rotated,

The lever 5 is rotated through the rotation shaft 6 of the valve 7 so that the handle 4 'of the gas valve 4 connected to the lever 5 is rotated to automatically shut off the gas valve 4 will be.

Here, since the fan gear 7 itself is formed at an angle of 90 degrees and is rotated within a range of 90 degrees by the stoppers 24 on both sides, the fan gear 4 is opened or closed in accordance with the rotation angle of the handle 4 ' And when it is necessary to manually shut off the gas valve 4 in addition to the occurrence of a fire, the manual button 22 projected to the outside of the casing 3 is pressed to rotate the ratchet 30 The handle 4 'of the gas valve 4 can be operated manually.
