摘　　要：探讨在惰性气体灭火系统管网设计时,通过选用相对较小规格的选择阀和减压孔板组成减压组件,达到减少选择阀规格系列,降低成本的目的,同时介绍与之对应的系统水力计算方法。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.

关 键 词：气体灭火系统 减压孔板 减压组件 选择阀 水头损失
