Abstract

PURPOSE:To improve the safety of the device in an emergency by a constitution wherein a gas passage is shut-off in an instant when a quake sensitive sensor is put in operation and as well as a very small amount of leakage sensing gas is flowed and, if the leakage of the gas is sensed, the resetting of the device is made impossible. CONSTITUTION:The device consists of a solenoid valve A with locking mechanism arranged in a gas supply pipe, a solenoid valve B which opens at energization arranged in series with a flow rate regulator C, which is equipped with a diaphragm and microswitches, in a piping by-passing the solenoid valve A, a gas meter D equipped with a rotation detector and a control panel E interlinkedly controlling the respective above-mentioned apparatuses. In addition, when the quake sensitive sensor or the gas sensor (neigher are shown) actuates, the solenoid valve A is rendered to be shut-off in an instant through a relay circuit. Furthermore, even if the resetting operation is tried under the condition that the leakage sensing gas is leaking at somewhere, the device is so constituted as to make the resetting operation impossible by opening a switch 3 with the lowering of the diaphragm of the regulator C due to the leakage of the gas.
