摘　　要：工程设计中,室外消火栓系统与室内消火栓系统合用的情况比较常见,但部分工程设计人员对这种合用系统的设置要点理解不透彻,经常出现设置不准确的情况。对室内外消火栓合用系统的特点进行了概括,对合用系统的消防水泵流量和扬程取值进行了举例分析,同时对设置3台消防水泵时的压力开关启动和流量开关启动值进行了明确;根据合用系统是否设置水泵接合器的两种情况,分别就合用系统消防主环管与室内消火栓管网连接处是否设置止回阀,以及如何设置稳压进行了分析。In engineering design,it is common for outdoor fire hydrant systems to be combined with indoor fire hydrant systems.However,some engineering designers do not have a thorough understanding of the key points of setting up such a combined system,and often encounter inaccurate settings.This article summarizes the characteristics of indoor and outdoor fire hydrant combined systems,analyzes the flow and head values of fire water pumps in the combined system with examples,and clarifies the pressure switch activation and flow switch activation values when setting up three fire water pumps;Based on the two situations of whether a water pump adapter is installed in the combined system,an analysis was conducted on whether a check valve is installed at the connection between the fire main loop pipe and the indoor fire hydrant pipe network in the shared system,and how to stable a pressure.
