摘　　要：自动喷水灭火系统中预作用系统适用于准工作状态时配水管道内不充水的场所,它是一种经济、有效的灭火手段。介绍了预作用系统的3种自动启动模式,分析了单联锁预作用系统、双联锁预作系统和无联锁预作用系统模式的特点,梳理了不同自动启动模式之间的差异,并提出了不同模式的适用场所和选择。明确了预作用系统的设计原则和设计参数,针对常出现的充气压力、喷头选型与报警阀检测、单联锁联动改进的问题进行了讨论。The preaction system of sprinkler systems is suitable for the place where the water distribution pipe is not filled with water in the quasi-working state.It is an economical and effective means of extinguishing fire.This paper introduced three kinds of automatic starting modes of preacting system,analyzes the characteristics of single interlock system,double interlock system and non-interlock system.This paper sorted out the differences between different automatic starting modes,and puts forward the selection of suitable places for different modes.The design principles and parameters of the preacting system are clarified,and the problems such as inflation pressure,nozzle selection,alarm valve detection and single interlock linkage improvement are discussed.
