消防排烟风机防火阀设备

消防排烟风机设备-防火阀,常开,70℃或者280℃关闭,一般安装在风管穿越防火墙和结构变形缝处,起火灾控制作用,可以设置输出电讯号,温度超过70℃或者280℃时阀门关闭,联动送(补)风机关闭。
安装在中央空调风道系统中,工作原理是利用阀门上安装的极易熔合金的温度控制,利用重力作用和弹簧机构的作用,当火灾发生时,火焰入侵风道,高温使阀门上的易熔合金熔解,或使记忆合金产生形变使阀门自动关闭,用于风道与防火分区贯穿的场合。

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。

消防排烟风机防火阀安装在排烟系统与通风空调系统兼用的风机入口处,平时处于“常开”状态,可通风,当管道内气流温度达280℃时,阀门靠易熔金属的温度熔断器动作而自动关闭,切断气流,防止火灾蔓延。
