摘要： There is provided a flow-blocking safety valve to prevent an explosion of a portable gas container, wherein, when the portable gas container overheats during use and the temperature rises above a predetermined level, a bridge hold supporting a pin of the safety valve melts and thus a pin or ball securely supported in the bridge holder becomes free to move to close a flow channel through which the gas flows, thereby blocking the gas discharge and preventing an accident occurring when the gas container bursts by overheating.
