The invention discloses a water mist fire extinguishing system with a partition control release function and a metro vehicle, and belongs to the technical field of metro vehicle fire extinguishing systems. According to the metro vehicle with the water mist fire extinguishing system with the partition control release function, the partition pipelines and four water mist nozzles of each partition are all controlled by adopting a corresponding partition control valve, and each compartment is controlled by adopting a trend control valve, so that the control mode can guarantee that when fire disasters occur in any half compartment, the corresponding partition control valves and the trend control valves can be opened. All the water mist nozzles are arranged, two of the four water mist nozzles in each partition are connected in series, and then every two of the four water mist nozzles are connected in parallel, so that the release amount of the nozzles in a release partition is relatively uniform. A water mist system module is mounted in the middle compartment of a fire control unit, so that the water mist can reach any fire control partition at the fastest speed.
本发明公开了具有分区控制释放功能的细水雾灭火系统及地铁车辆,属于地铁车辆灭火系统技术领域。具有分区控制释放功能的细水雾灭火系统的地铁车辆,各个区域的分区管路和四个细水雾喷头,均采用一个对应的分区控制阀控制,每个车厢均采用走向控制阀控制,此控制方式能够保证,任何半节车厢中出现火灾情况,均可打开相应的分区控制阀和走向控制阀,将各个细水雾喷头进行布置,每个分区中的四个细水雾喷头,其中两个细水雾喷头先进行串联,两两串联之后在进行并联设置,以达到释放分区内喷头释放量相对均匀,将细水雾系统模块安装在控火单元的中间车厢,使细水雾能够以最快的速度达到任一控火分区。
