摘　　要：对一种高压混合气体灭火系统中主要部件及管网的流体力学实验研究工作作了介绍。使用实验方法对高压气体灭火喷嘴的流量特性、非标准(Φ50mm以下)减压孔板的减压特性进行了系统的研究;对复杂管网系统的流动特点进行了初步探讨。为灭火系统的设计和部件选型提供了可靠的实验依据。The experiments of pipe-net and main parts of extinguishing system working with high pressure mixed gases are introduced. The mass flux performance of the spray nozzle and nonstandard orifice plate in high-pressure extinguishing system is investigated roundly by using experimental method. The flow characteristic of complex pipe net system is primarily tested and discussed. The reliable experiment results are provided to design and choose the equipments of the extinguishing system.
