piston deluge valve

Based on engineering examples the paper introduces some matters that need to be considered in the design of water spray fire extinguishing system,such as determination of design flow,selection and arrangement of spray head,arrangement of deluge valve block and laying of water spray pipeline,as well as operation and control of system and selection of water source and pumps,etc.

结合工程实例,介绍了水喷雾灭火系统设计过程中设计流量的确定、喷头的选择与布置、雨淋阀组的布置、水喷雾管道的敷设、系统操作与控制、水源水泵的选择等应该注意的问题。
