摘　　要：对自动喷水灭火系统3种自动启动器件的可靠性及存在的风险进行详细分析,针对GB 50084-2017《自动喷水灭火系统设计规范》第11.0.1条的相关讨论开展分析,并就自动喷水灭火系统的可靠性、安全性等方面的问题,提出:对于湿式自动喷水灭火系统,报警阀组报警管路上的压力开关直接启动消防水泵是系统最优的配置,符合湿式系统及时启动、安全灭火的要求。The reliability and existing risks of the three automatic starting devices of the automatic sprinkler system are analyzed in detail.In view of the conflict between Article 11.0.1 of GB 50084-2017 Code for design of automatic sprinkler systems and other standards,and the problems in the reliability and safety of the automatic sprinkler system,the paper proposes that:for the wet automatic sprinkler systems,the pressure switch on the alarm pipeline of the alarm valve group directly starts the fire pump,which is the optimal configuration of the system and meets the requirements of timely startup and safe fire extinguishing of the wet system.
