Abstract: This paper discusses the design of the pipe network of inert gas fire extinguishing system, by selecting a relatively small size selection valve and pressure reducing orifice plate to form a pressure reducing component, so as to reduce the selection valve specification series and reduce the cost, and introduces the corresponding system hydraulic calculation method.

Key words: gas fire extinguishing system, pressure reducing orifice plate, pressure reducing component, selection valve, head loss
