摘要
P To avoid reductions in convenience in the use of a gas appliance due to the exceeding of a maximum amount of change held by a gas shut-off device over a total gas consumption. PSOLUTION: The gas shut-off device includes a flow rate detection part 11, a flow rate calculation part 12, an increase and decrease calculation part 13, an increase and decrease determination part 14, a valve driving part 15, a valve 16, and an isolation correction part 17. The increase and decrease determination part 14 deletes a change amount C once held by the gas shut-off device ON the basis of a correction request signal G determined by the isolation correction part 17 and registers an actual flow rate of gas as a new change amount C to prevent the period of time of gas use until the closing of a gas passage from being shortened ON the basis of an unrealistic change amount C.
