防火阀是一种记忆熔合金的温度控制,云南防火阀浙江11选5走势图利用重力作用和弹簧机构的作用关闭的阀门形式。新型产品中亦有利用记忆合金产生形变使阀门关闭的。厨房、浴室和厕所等的排风管道与竖井连接时也应采取相应措施防止火势沿着排风管在各楼层间蔓延。厨房、浴室和厕所等的排风管道与竖井相连时,云南防火阀若无防止回流的措施时应在支管上设置防火阀;当有防止回流的措施时,可不设防火阀。当烟气温度达到280℃时,人已基本疏散完毕,排烟已无实际意义,而烟气中此时已带火,阀门自动关闭,以避免火势蔓延。

一般设在通风空调管路穿越防火分区处。平时开启,火灾时关闭以切断烟、火沿通风管道向其他防火分区蔓延。由安装在阀体中的温度熔断器带动阀体连动机构动作的防火阀。云南防火阀厂家该温度熔断器的易熔片或易熔环熔断温度70℃,这类防火阀用的最多。安装时要特别注意,温度熔断器一定要应着气流方向安装。云南风机告诉你当防火阀带有调节功能时,又称为防火调节阀。根据工程需要,有的防火阀上既设有温度熔断器又与烟感器联动,这类阀门称为防烟防火阀。在兼用系统中,有的在干管上设排风口。排烟时改风口就应关闭,这时可采用防火阀与百叶风口组合而成的防火风口。
