  • Indication Of The Valve Opening Or Closing Status (AREA)

Abstract

PURPOSE:To speedily and surely confirm the opening/closing state of a gas valve by memorizing a processing the output signal of a gas sensor for detecting the opening completion state or the closing completion state of the gas valve and displaying the result. CONSTITUTION:When the reflecting light of a reflecting plate 25 is received by only an optical fiber sensor head 28 on the opening side opposed to the reflecting plate 25, a signal is transmitted to a processing device 38 through a receiver 37, and a processing for putting a gas valve into the opening completion state is performed. In the gas valve closing completion state, the reflecting light of the reflecting plate 25 is transmitted onto the optical fiber sensor head 29 on the closing side, and a processing for putting the gas valve into the closing completion state is carried out. The opening/closing state of the gas valve 21 is memorized in the processing device 38 and displayed on a CRT 39.
