对自动喷水灭火系统末端试水装置、系统流量压力检测装置、报警阀报警流量生产单位公布值的作用和相关概念进行介绍,提出应准确理解系统“最不利点处喷头(或末端试水装置)的工作压力”。同时对报警阀的报警流量和系统中应安装系统流量压力检测装置进行了概述,以期在自动喷水灭火系统设计时能既保证设计安全可靠,又能取得较好的经济效果。
This paper introduces the role and related concepts of the end test water sprinkler system of the sprinkler system, the system flow pressure testing device, the alarming valve alarm flow rate production unit’s published value and proposes that the system should be correctly understood at the most disadvantageous point Device) working pressure ". At the same time, the alarm flow of the alarm valve and the system flow and pressure detection device should be installed in the system. In order to ensure the safety and reliability of the design of the sprinkler system, the system can achieve better economic results.
