になっていた。In the conventional gas supply system, as shown in Fig. 1, a pipe 2 is connected to a gas pump 1, and a regulator 3 with a pressure gauge is connected to the gas pump 1.
The gas supplied from the gas cylinder 1 is depressurized and the stop pulp 4 is opened.
The system was such that the gas was supplied up to the point where the flow rate was throttled by the needle pulp 5 and reached the gas usage section 6.

ぼす。When gas is flowed through such a gas supply system, it is not possible to quickly determine if a small amount of leakage occurs due to a pinhole in the piping joint 7 or the piping 2 itself. In particular, if such leakage occurs in piping that uses toxic gases such as s tH, PHII I Btl (8), it may cause ignition of other combustible materials or adversely affect the human body.

るガス供給システムにある。The present invention solves the above-mentioned problems and is characterized by attaching one or more gas flow rate detectors to the gas piping and comparing the outputs of the detectors with a comparator. It has a gas supply system that can quickly detect gas leaks between detectors.
以下に本発明の実施例を第２図によシ説明する。An embodiment of the present invention will be explained below with reference to FIG.
第２図に示すように本発明は配管２の途中に１対のガス
流量検出器８を設けその検出器８と、比較器１０の間は
信号線９でつながれている。As shown in FIG. 2, in the present invention, a pair of gas flow rate detectors 8 are provided in the middle of the pipe 2, and the detectors 8 and the comparator 10 are connected by a signal line 9.
以上のような構成になっているのでガス流量検出器８間
でガス漏れが生じた場合比較器１０に入る信号が異なる
ため、比較器１０によシすばやくやくガス漏れが検知出
来る。With the above configuration, when a gas leak occurs between the gas flow rate detectors 8, the signals input to the comparator 10 are different, so that the comparator 10 can quickly detect the gas leak.
第３図はこの比較器よシ外部への信号線の利用方法の１

る。Figure 3 shows one way to use the signal line from this comparator to the outside.
It refers to one thing. In Figure 3, the signal line 11 from the comparator to the outside activates the magnetic valve 12, which closes the air operated pulp 13 in front of the gas flow rate detector 8, and automatically stops the gas supply. It was designed to let you do so.
尚、第２図、第３図で第１図と同一の機能のところは同
じ符号で示している。In FIGS. 2 and 3, the same functions as those in FIG. 1 are designated by the same reference numerals.
以上説明したように本発明のガス供給システムを使用す

人体への悪影響を防ぐことが出来るものである。As explained above, by using the gas supply system of the present invention, if a gas leak occurs in the middle of the piping, the gas leak can be detected immediately, preventing ignition of other combustible materials.
It can prevent adverse effects on the human body.
