Document Type and Number:
Japanese Patent JPH09133237
Kind Code:
A
Abstract:
To prevent wrong shutoff without stopping the use of gas.
This gas cutout gear is equipped with a gas alarm 5 which outputs, when detecting gas leakage, a gas leakage alarm signal to information means 6, and a gas leakage definite signal to a control part 10 for controlling a cutoff valve 2, and gas flow detecting means 8 for outputting a flow signal according to a passing gas amount. When such a condition can presume that the gas alarm 5 may wrongly alert, since being transmitted to invalid switching means 70, a signal by which the gas leakage definite signal is canceled by manual input, a passage may not be shut off by the cutoff valve 2.
