Title:
GAS INTERRUPTION APPARATUS
Document Type and Number:
Japanese Patent JP3542219
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To automatize opening of a valve by instructing the time, reconcile safety and convenience, and improve reliability of a gas interruption apparatus.
SOLUTION: A valve opening time instruction signal B is outputted from a sensor monitoring part 1 through a communication receiver part 2, and a valve is opened with a valve opening/closing driving part 4 following a valve opening signal C when the time reaches a specific time set in association with the valve opening instruction time in a valve opening instruction part 3. Further, the existence of leakage is judged in a leakage detection part 6 based upon a flow rate signal of a flow rate detection part 5 whereby a gas use allowance signal or a gas use interruption signal is outputted. When the gas use interruption signal E is outputted, a valve closing instruction part 7 outputs a valve closing signal H and hence the valve opening/closing driving part 4 closes the valve.
