Gas valve shut-off valve opening / closing control device

Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 ガスメータの遮断弁の開閉状態を知りたいと き、その確認のためのスイッチを単に操作するだけで、 遮断弁の開閉状態を随時にしかもそのときだけ電池消耗 少なく表示できる遮断弁開閉制御装置を提供する。 【構成】 遮断弁開スイッチ１６を操作して遮断弁を開 くと、該遮断弁が開状態であることが遮断弁開閉記憶回 路３２に記憶保持される。遮断弁閉スイッチ１７を操作 して遮断弁を閉じると、該遮断弁が閉状態であることが 遮断弁開閉記憶回路３２に記憶保持される。遮断弁開閉 状態確認スイッチ１８を操作すると、遮断弁開閉記憶回 路３２に記憶の開閉状態が読出回路４１・４２で読み出 され、遮断弁が開状態であるときは開表示用ＬＥＤ１９ により、閉状態のときは閉表示用ＬＥＤ２０によって表 示される。 (57) [Abstract] [Purpose] When you want to know the open / closed state of the shutoff valve of a gas meter, simply operate the switch to check it. Provided is a shutoff valve opening / closing control device capable of displaying the open / closed state of a shutoff valve at any time and only at that time with low battery consumption. When the shutoff valve opening switch 16 is operated to open the shutoff valve, the shutoff valve open / close memory circuit 32 stores and holds that the shutoff valve is in an open state. When the shutoff valve closing switch 17 is operated to close the shutoff valve, the shutoff valve open / close memory circuit 32 stores and holds that the shutoff valve is in the closed state. When the shutoff valve open / closed state confirmation switch 18 is operated, the open / closed state stored in the shutoff valve open / close memory circuit 32 is read by the read circuits 41 and 42. When the shutoff valve is open, the open display LED 19 is displayed. As a result, in the closed state, it is displayed by the close display LED 20.
