本発明はガス供給の総合的な安全を保証するガス遮断装
置に関するものである。Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a gas cutoff device that guarantees the overall safety of the gas supply.
従来の技術
近年、ガス遮断装置はマイクロエレクトロニクスの発達
により小型で低コストになり一般家庭にも普及してきて
いる。BACKGROUND OF THE INVENTION In recent years, due to the development of microelectronics, gas shutoff devices have become smaller and lower in cost, and have become widespread in ordinary households.
以下図面を参照しながら上述した従来のガス遮断装置の

弁（以下遮断弁と呼ぶ）である。An example of the conventional gas cutoff device described above will be described below with reference to the drawings. FIG. 2 shows a configuration diagram of a conventional gas cutoff device. In Fig. 2, 1 is a gas meter, 2 is a flow t sensor attached to gas meter 1, 3 is a diaphragm pressure sensor attached to gas meter 1, 4 is a control unit, and 5 is a self-holding type gas path leading to gas meter 1. This is a cutoff valve (hereinafter referred to as a cutoff valve).
以とのように構成されたガス遮断装置について、１：１
．下その動作について説明する。矢印の如くガスが流れ
、流量センサ２からガス流量信号を制御部４に伝える。Regarding the gas cutoff device configured as follows, 1:1
．． The operation will be explained below. Gas flows as shown by the arrow, and a gas flow rate signal is transmitted from the flow rate sensor 2 to the control unit 4.

駅弁５を動作させ、ガス通路を遮断する。The control unit 4 operates the shutoff valve 5 to shut off the gas passage when there is an abnormality in the gas flow rate or when a certain flow rate continues for an abnormal time. In addition, the diaphragm-type pressure sensor 3 detects the drop in pressure on the downstream side due to gas leakage from the meter, and
The station valve 5 is operated to shut off the gas passage.
発明が解決しようとする問題点
しかしながら、メータの上流側にもコックがついており
、最近の消費者は夜中はこのコックを止しる人が多くな
ってきている。このコックを止しると圧力センサがはた
らき、下流側の圧力低下でないのに遮断弁が止してしま
う。安全装置として作動するはずのガス遮断装置が安全
なときに遮断し、消費者の混乱をまねく。また、制御部
センサ類が故障した場合には直列的な信頼性構成しこな
っているため遮断弁が作動しなくなり危険な状態になる
可能性がある。Problems to be Solved by the Invention However, there is also a cock on the upstream side of the meter, and more and more consumers these days turn off this cock during the night. When this cock is turned off, the pressure sensor is activated, and the shutoff valve is turned off even though there is no pressure drop on the downstream side. The gas cutoff device, which is supposed to operate as a safety device, shuts off when it is safe to do so, causing confusion for consumers. Furthermore, if the control unit sensors fail, the shutoff valve may not operate due to the unreliable series configuration, which could lead to a dangerous situation.
問題点を解決するだめの手段
と記問題点を解決するために本発明のガス遮断装置は、
従来の構成のダイヤフラム式の圧力センサのかわりに、
ガス通路の自己保持型遮断弁の下流側に弁座と球体とそ
の球体を弾性体で固定した圧力弁と、前記圧力弁の球体
の変動を検出し制御部へ入力する検出部を備えている。Means for Solving the Problems In order to solve the problems described above, the gas cutoff device of the present invention has the following features:
Instead of a diaphragm pressure sensor in the traditional configuration,
A valve seat, a sphere, a pressure valve in which the sphere is fixed with an elastic body, and a detection unit for detecting fluctuations in the sphere of the pressure valve and inputting the detected changes to the control unit are provided on the downstream side of the self-holding shutoff valve in the gas passage. .
作 用

たりがヌ聞れを停止させる。また元コックを止めても圧
力弁ははたらかない。また検知部により圧力の低下を制
御部に知らせ遮断弁を止じることができる。Function: With the above-described configuration, the sphere is pushed and hits the valve seat to stop the vibration when the pressure on the downstream side of the meter decreases due to gas leakage. Also, even if the original cook is stopped, the pressure valve does not work. Further, the detection section can notify the control section of a decrease in pressure and can stop the shutoff valve.

メータの内壁に固定し、一方には球体６がついている。In Figure 1, the same numbers as in Figure 2 represent the same thing,
It is also functionally the same as the conventional example. 6 is a sphere with a magnet embedded inside, 7 is a 7 ring as an elastic body, one side is fixed to the inner wall of the meter, and the other side has the sphere 6 attached.

止しても圧力弁が働くことがなく、従来のダイヤフラム
式の圧力センサのように誤作動することがない。The operation of the gas cutoff device configured as described above will be described below with reference to FIG. 1. When there is a pressure drop on the downstream side due to gas leakage, the ball 6 hits the valve seat 8 against the force of the spring 7 and automatically shuts off the gas. In addition, the reed switch 〇 notifies the control unit 4 that there has been a decrease in pressure due to the fluctuation of the sphere 6, and the shutoff valve 5 is shut off to cut off the gas passage ft. According to this, even if the control section is out of order, the pressure valve shuts off the gas passage, resulting in parallel reliability W, which increases reliability. In addition, the pressure valve does not operate even if the main cock is turned off, and there is no possibility of malfunction unlike conventional diaphragm pressure sensors.
発明の効果 以上のような本発明の効果について以下に述べる。Effect of the invention The effects of the present invention as described above will be described below.
（１）従来のダイヤフラム式圧力センサに比べ、力゛ス
通路を遮断する機能として遮断弁と圧力弁という並列的
な信頼性の構成がとれ、ガス遮断装置の信・項性をとげ
ることができる。(1) Compared to conventional diaphragm-type pressure sensors, a reliable configuration with a shutoff valve and a pressure valve in parallel can be used as a function to shut off the force passage, and the reliability and reliability of the gas shutoff device can be improved. .
（２）元コックを止じることによる誤作動がなくなり、
消費者の混乱を防ぐことができる。(2) Eliminates malfunctions caused by stopping the former cook;
Consumer confusion can be prevented.
（３）ダイヤフラム式の圧力センサと圧力弁は最終機能
としては同じであるにもかかわらず、ダイヤフラム式は
ガス通路とのキ密性を保たなければならなく、ガス漏れ
の危険性があるが圧力弁は力′ス通路と検出部が完全に
独立でガス漏れの・０配がなく、信頼性があがる。(3) Although diaphragm-type pressure sensors and pressure valves have the same final function, diaphragm-type pressure sensors must maintain tightness with the gas passage, and there is a risk of gas leakage. In the pressure valve, the force passage and the detection part are completely independent, so there is no risk of gas leakage, improving reliability.
