Abstract

(57) [Summary] [Purpose] To provide a signal extraction structure for an alarm that does not require routing of signal lines and has an excellent indoor appearance. [Structure] A detection signal emitted from an alarm device 10 is transmitted to a cutoff valve of a gas meter 4 via existing gas pipes 6 and 22, and the cutoff valve is activated.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on a gas leak alarm installed indoors (hereinafter simply referred to as an alarm). The detected gas leak detection signal is transmitted to the gas meter's shutoff valve, and the shutoff valve is activated. This invention relates to a signal extraction structure for a closing alarm.

0002

[Conventional technology]

An alarm device that detects indoor gas leaks and activates the shutoff valve built into the gas meter. , widely used to prevent accidents. Figure 3 shows the conventional alarm signal extraction structure. An example is shown. In the figure, a gas cylinder 1 installed outdoors is connected via a pressure regulator 2. It is connected to a gas meter 4 by a pipe 3. Gas meter 4 was buried underground It is connected to indoor piping 6 via a flexible gas pipe 5. And indoor piping 6 is branched off and connected to various combustion devices 7 installed indoors. Also gas pipe 5 Valves 8 and 9 are provided at the outlet of the pipe and the indoor pipe 6, respectively.

0003 The alarm 10 is installed at a predetermined position such as an indoor wall, and is connected to an electric light (not shown). connected to the line. In addition, the signal line 11 of the alarm 10 passes through the wall 12 and connects to the outdoors. It is taken out, extended along the gas pipe 5, and connected to a cutoff valve (not shown) of the gas meter 4. It is continued. When the alarm 10 detects a gas leak, it will sound an alarm such as a buzzer. At the same time, the detection signal is transmitted to the shutoff valve via the signal line 11, and the shutoff valve is activated. It is supposed to close.

0004

[Problem that the idea aims to solve]

However, according to the conventional alarm signal extraction structure configured as above, Not only does it take time and effort to route the signal line 11 indoors, but it also When installing the alarm 10 on an object, the signal line 11 must be routed along the wall. Otherwise, the appearance becomes unsightly. Furthermore, at the part where the signal line 11 penetrates the wall part 12, However, there are problems such as the need to perform waterproofing and appearance treatments on the inside and outside. there were.

[0005] Therefore, the purpose of this invention was to solve the above-mentioned problems. To provide an alarm signal extraction structure that does not require running wires and has an excellent indoor appearance. be.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, this invention is based on a gas leak alarm installed indoors. The signal output structure of the alarm transmits the detection signal emitted from the gas meter to the gas meter's shutoff valve. The detection signal emitted from the alarm is sent to the cutoff valve via the existing gas piping. The system is characterized in that it is configured to transmit the signal to the user and operate the shutoff valve.

[0007]

[Effect]

According to the above configuration, the detection signal emitted from the alarm is sent via the existing gas piping. It can be transmitted to the gas meter's shutoff valve, so there is no need to install a separate signal line. This simplifies construction and improves the indoor appearance.

【Example】

An embodiment of this invention will be described below with reference to the drawings.

[0009] FIGS. 1 and 2 show the configuration of an embodiment of this invention. In these figures, Figure 3 The parts corresponding to the parts of the conventional example shown in are shown with the same reference numerals, and their explanations are given as appropriate. Omitted. FIG. 1 shows only the main parts related to this invention.

0010 In this embodiment, a detection signal from an alarm 10 is sent to the gas pipe 6 on the indoor side. While installing the operating ultrasonic oscillator 21, the ultrasonic oscillator 21 is attached to the outdoor gas pipe 22 a receiving unit 23 that detects motion and outputs a signal to close a shutoff valve (not shown). It is installed.

[0011] To further explain with reference to FIG. 2, when the alarm 10 detects a gas leak, The ultrasonic oscillator 21 starts operating according to the detection signal of the gas pipe 6, 22 to the receiving unit 23. The receiving unit 23 receives ultrasonic vibrations. When detected, a shutoff valve close signal is output and the shutoff valve is closed.

0012 According to this embodiment, the detection signal emitted by the alarm 10 is converted into an ultrasonic vibration signal. is transmitted to the receiving unit 23 via the gas pipes 6 and 22 to close the shutoff valve. This eliminates the need for signal lines, making construction easier and improving the interior appearance.

[0013]

[Effect of the idea]

As explained above, according to this invention, gas leaks emitted from indoor alarms can be detected. The detection signal is transmitted to the gas meter's isolation valve via the existing gas piping, and this isolation valve Since the system operates, signal lines are no longer required, construction is easy, and the indoor appearance is improved. do.
