Description

Fire disaster prevention damage-stopping safety valve Technical Field The utility model relates to the technical field of security equipment, in particular to a fire disaster prevention damage prevention safety valve. Background In the use process of gas or natural gas pipelines, cases of fire occurrence caused by leakage are frequently reported in real life, a great part of reasons for occurrence of such accidents are that when the gas leakage occurs in the fire, the gas pipelines near the fire source cannot be effectively cut off, the fire is further amplified, finally the fire is caused to occur in a large area even in an explosion manner, once the fire occurs in a gas stove in a household, the gas stove basically uses on-site personnel to risk to close a valve to control the fire without automatically cutting off the pipeline, and certain relatively intelligent devices are used for controlling the on-off of the pipeline, but the application cost is too high, so that the gas stove is unfavorable for the popularization of the application of ordinary families, and the design of a safety valve with relatively low cost and strong practicability is also very necessary. Disclosure of utility model The utility model aims to provide a fire prevention damage prevention safety valve aiming at the situation, and the safety valve can achieve a more efficient fireproof effect through a brand new structural design.
