摘要
An inert gas fire fighting system is designed to extinguish fire by discharging inert gas fire extinguisher stored in a gaseous state in a fire extinguisher storage vessel into an object fire fighting section while maintaining the concentration of the inert gas fire extinguisher in the object fire fighting section at no less than the fire extinguishing concentration. A vessel valve of the fire extinguisher storage vessel is a pressure control valve which controls the gas pressure P of the inert gas fire extinguisher on the discharge side to no more than the reference gas pressure P0 determined by a gas pressure P1 of a constant-pressure gas source. This makes it possible to increase the charging pressure of the inert gas fire extinguisher without increasing the pressure resistance grade of the secondary side equipment units of the fire fighting system.
