<P>PROBLEM TO BE SOLVED: To provide an emergency gas cutoff method and a gas circuit-breaker which can properly restrai gas leakage, regardless of a state of a damage site of a gas conduit. <P>SOLUTION: The gas cutoff method is performed in an emergency for restraining the gas leakage from the gas conduit, and uses an injection-curing material which can adjust a curing time in response to a change in the illustrated liquid temperature, and adjusts the liquid temperature of the injection-curing material in response to use or the peripheral air temperature, and injects-fills the liquid injection-curing material in the leaking-out place periphery of the gas conduit and the inside of the gas conduit, to be cured after injection-filling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
