- ガス配管に接続されてガスの供給及び遮断を行う遮断弁を内蔵した弁体部と、該弁体部の遮断弁を駆動する駆動機構とガス圧を計測する圧力センサを内蔵した弁駆動部と、を備えたガス遮断弁であって、
前記弁体部に内蔵された前記遮断弁の従動軸が該弁体部の外部に気密を保って露出されるとともに、前記弁駆動部には該従動軸に連結及び分離可能な前記駆動機構の駆動軸が設けられ、
前記弁体部には前記弁駆動部の取付箇所に、前記圧力センサにガス圧を導入するための連通孔が設けられるとともに、該連通孔には該連通孔の開状態及び閉状態を切り換える逆止弁が設けられ、
前記弁駆動部を前記弁体部に取り付けた状態で該弁駆動部が前記逆止弁に接触して該逆止弁が開状態となり、該弁駆動部が該弁体部から分離された状態で該逆止弁が閉状態となるよう構成されていることを特徴とするガス遮断弁。 - 前記逆止弁は、前記連通孔内に配設されるとともに、該連通孔の前記圧力センサ側のノズル部に接離可能な弁体と、該弁体を該ノズル部方向に付勢する付勢手段と、該弁体に一体に取付られて前記ノズル部を介して前記弁駆動部の取付箇所に突出する弁棒とを備え、
前記弁駆動部が該弁棒に接離することにより、前記逆止弁を開閉することを特徴とする請求項1に記載のガス遮断弁。 - 前記弁駆動部は前記連通孔から前記圧力センサにガス圧を導入する圧力導入孔を有し、
前記逆止弁は、前記ノズル部が前記連通孔の中心に形成されるとともに、前記弁棒が前記連通孔の中心で前記ノズル部を介して前記弁駆動部の取付箇所に突出されるよう構成され、
前記連通孔の中心軸と前記圧力導入孔の中心軸とを偏心させたことを特徴とする請求項2に記載のガス遮断弁。 - 前記弁駆動部の前記駆動軸と前記遮断弁の従動軸とが、挿入及び引き出し可能な連結ピンにより連結及び分離可能となっていることを特徴とする請求項1乃至3のいずれか一項に記載のガス遮断弁。
