排烟罩工程施工的排烟系统防火阀主要应用于自然通风和空调机组,排烟系统防火阀一般安装在排风系统和空调机组主机房防火隔开处,为70℃防火阀,正常开启和关闭时,当排烟系统温度达到70度时,通风风管内烟尘温度达到全自动70度。全自动化的操作方法。
The fire damper of the smoke exhaust system in the construction of the smoke exhaust hood is mainly used in the natural ventilation and air conditioning units. The fire damper of the smoke exhaust system is generally installed in the fire compartment between the exhaust system and the main engine room of the air conditioning unit. It is a 70 ℃ fire damper. When it is normally opened and closed, when the temperature of the smoke exhaust system reaches 70 ℃, the smoke temperature in the ventilation duct reaches 70 ℃. Fully automatic operation method.
排烟防火阀主要应用于机械设备排烟系统软件,是一种280℃的防火阀,正常为常闭,火灾发生时受火警自动报警的连动数据信号全部自动打开,另外配有手动执行机构,既可以手动开启,又可以在消防安 全监控中 心遥控开启(即连动操纵,手动操作,自动控制系统三种方式),一般安装在排烟口,通风风管穿越重生防火安 全,防烟分区隔开处,排烟主机房通风风管过墙处,当通风风管温度达到280度时关闭。
Smoke extraction fire damper is mainly used in the smoke extraction system software of mechanical equipment. It is a 280 ℃ fire damper, which is normally closed. When a fire occurs, all the linked data signals automatically open. In addition, it is equipped with a manual actuator, which can be opened manually or remotely in the fire safety monitoring center, The automatic control system is generally installed at the smoke exhaust outlet, the place where the ventilation duct passes through the rebirth fire safety, the place where the smoke control partition is separated, and the place where the ventilation duct of the smoke exhaust main engine room passes through the wall. When the temperature of the ventilation duct reaches 280 ℃, it will be closed.
其中一个方法是将排烟口的排烟阀和控制模块撤消,将出风口改为单面百叶窗;另一个方法是将各层排烟头上电动常闭的防火阀改为开启与关闭均为280度关闭的防火阀,
One of the methods is to cancel the exhaust valve and control module of the exhaust outlet, and change the air outlet into a single-sided shutter; Another method is to change the electric normally closed fire damper on the smoke exhaust head of each floor into a fire damper with 280 degree opening and closing,
排烟口按所受压力系统分区进行开启操作,排烟口可由消防安全管理远程控制,并可就地手动开启.全部排烟风机设置一个全自动关闭的排烟防火阀,当烟气温度达到280℃时,该防火阀将全自动关闭,并且连动排烟风机终止,并规定离心风机可在280℃时持续工作中30min。
The smoke outlet is opened according to the pressure system partition. The smoke outlet can be remotely controlled by the fire safety management center, and can be manually opened locally. All smoke exhaust fans are equipped with a fully automatic fire damper. When the flue gas temperature reaches 280 ℃, the fire damper will be fully automatic closed, and the continuous smoke exhaust fan will terminate, The centrifugal fan can work continuously for 30 minutes at 280 ℃.
全部安装在装修吊顶内的排烟管路均选用难燃原料包,且与之的间距不小于mm,当空调通风管穿过重生防火安全区时,该不燃原料包被不燃.7甲ld乙ld丙类生产制造工业厂房的送ld排风系统道宜分层设置,但进至生产制造工业厂房的水平或竖直排风管设置一个防火阀时,每层均要加水。
When the central air conditioning ventilation pipe passes through the fire safety area, the non combustible material package is non combustible. The air supply and exhaust system of 7 class A, B and C industrial buildings should be arranged in layers, However, when a fire damper is set up in the horizontal or vertical exhaust pipe of the manufacturing industrial plant, water should be added to each floor.
