1.排烟防火阀(常闭,电讯号开启,280度熔断关闭,或手动关闭)一般应用于排烟系统中,可在排烟风机吸入口安装一个,火灾时由消控室控制开启,关闭时也可连锁关闭该排烟风机。 2.排烟阀,同上述3,各个单位叫法不同,有的根据它的动作温度叫做排烟阀,有的根据它的用途性质叫做防火阀,但是对于设备方只是把普通防火阀的熔断金属换成280度熔断的那一种. 3. 全自动排烟防火阀(地铁工程用)地下铁道通风、空调系统的防火、排烟阀门具有与火灾自动报警设备及气体灭火系统联动控制的功能。每台全自动防烟防火阀有两个独立电动控制信号,分别由EMCS、气消系统进行监控,控制信号均为DC24V±10%信号。每台全自动防烟防火阀有六个独立反馈信号(三个开到位,三个关到位)反馈信号均为常开无源接点信号。 排烟口: 如果你在管路上安装了必要的排烟阀,就用普通的单层百叶风口即可;否则需用板式排烟口,它同时带有排烟防火阀的机构。

译文:
Exhaust valve: A smoke damper (normally closed, open telecommunications number, 280 fuse shut down or manually shut down) is generally used in the exhaust system, install an exhaust fan suction control to open fire by the fire control room, turn off when the chain to close the exhaust fan. 2 exhaust valves, with the 3, various units of different names, and some called according to its operating temperature of the exhaust valves, and some called the fire damper according to the nature of its use, but only for the equipment side of ordinary damper fuse metal replaced that fuse 280 degrees. Automatic smoke damper (MTR engineering) Underground Railroad ventilation, air conditioning system of the fire, the exhaust valve and automatic fire alarm equipment and gas fire extinguishing system control linkage. Each automatic smoke fire damper has two separate electrical control signals, respectively, by the EMCS in gas consumption, system monitoring, and control signals are DC24V ± 10% signal. Each automatic smoke fire damper has six independent feedback signal (three open place, three off place) feedback signals are normally open passive contact signal. Exhaust port: If you have the exhaust valve installed in the pipeline, with the ordinary single-Louver can; otherwise required plate exhaust port, which at the same time with the institutions of the smoke damper.
