成について具体的に説明する。 However, as stated above, the reason why the present invention uses a gas cutoff mechanism that specifically stops the gear mechanism, etc. in the gas flow rate integration counter in the gas meter is that the mechanism in the gas meter Therefore, there is no need to install a shutoff device in the piping outside the gas meter, and there is no risk of gas leakage in the piping from the gas meter to the gas meter, and the gas shutoff mechanism is integrated inside the gas meter. This makes it economical and extremely easy to handle.A gear mechanism is installed on the gas flow rate accumulation indicator counter inside the gas meter, and by stopping the gear mechanism, the system operates in conjunction with this. The gas flow is cut off by automatically closing a motion valve (such as a rotary valve or a slide valve) provided in the valve. The configuration will be specifically explained below.

る。 As mentioned above, this invention is equipped with a shutoff mechanism inside the gas meter to prevent gas from leaking.
Alarm device 1 operates and issues the required alarm, and
The electromagnet 2 conducts and transmits the operation to the gas cutoff actuator 3 provided in the gas meter, and the actuator 3 is connected to the integration interlocking device 6 and the gas flow rate integration instruction counter 9 (hereinafter abbreviated as counter 9), which are responsible for gas supply. ) by stopping the gears etc.
Not only does it cut off the gas flow, but it also lights up the lamp.
This system is designed to cause a buzzer to sound to prevent secondary disasters caused by leaked gas.

にしたことを特徴とするものである。 That is, in the present invention, when a gas leak occurs, the electromagnet 2 is activated at the same time as the alarm 1 emits the alarm, and its magnetic action attracts and attaches the gas cutoff actuating body 3. It is characterized in that its tip acts on the gear mechanism 6' and integration interlocking device 6 to stop them, thereby automatically shutting off the gas.
次に、上記各場合の実施例を図面に基づいて説

流通は遮断されるものである。 In the case of a gear mechanism 6' (see Fig. 6) or when the integration interlocking device 6 is a gear mechanism (see Fig. 3), when the alarm is activated, the protruding tip 3 of the gas cutoff actuating body 3 -1 is a partial gear 11 in the gear mechanism
or the pawl 3-2 at the tip of the gas cutoff actuating body 3 meshes and engages with a part of the gear 11 in the gear mechanism (see Fig. 4). , the gear mechanism may be formed to stop. As shown in FIG. 6, when the gear mechanism 6' in the counter 9 is stopped, the operation of the interlocking device 6 connected thereto is also stopped, so that the gas flow is cut off as expected.

にすることもできるものである。 Note that the return is also carried out smoothly due to the action of elasticity. In addition, there is also a motion valve (rotary valve or slide valve) 17 connected to the counter 9.
Alternatively, the gas can be shut off by transmitting the operation of the gas shutoff actuator 3 and stopping it.

果は甚だ大なるものがある。 In each of the above cases, if the gas cutoff actuator 3 operates at the required time, the integration interlocking device 6 or the counter gear mechanism 6' will be stopped.
Gas flow is cut off. Therefore, not only the operation of the alarm 1 but also the gas flow is cut off at the same time, thereby preventing secondary disasters, and at the same time shutting down the lamps,
Since the buzzer also operates as required to notify you, its effects are enormous.
そして、本考案装置が所要に作動した後は警報

（第３図〜第５図参照）。 Therefore, in the present invention, a manual return mechanism 12 is provided in case automatic return is difficult due to some reason such as the gear mechanism inside the meter becoming distorted due to gas pressure or the like while the electromagnet is activated. That is, a shaft rod 13 whose lower end is located close to the gas cutoff actuating body 3 is inserted through the upper lid 8 of the gas meter 7, and the ammunition 16 is wound through the press seat 15 within the frame 14 provided on the inner wall. When the shaft rod 13 is pushed, the gas cutoff actuator 3 is pushed downward and the electromagnet 2 is
It is designed so that it can be separated from the center and returned to its original state (see FIGS. 3 to 5).
