防火阀[FIRE SAFE VALVE]

防火阀是指安装在通风、空调系统的送、回风管路上，平时呈开启状态，火灾时当管道内气体温度达到70℃时自动关闭，在一定时间内能满足耐火稳定性和耐火完整性要求，起隔烟阻火作用的阀门。排烟防火阀是指安装在排烟系统管道上，平时呈开启状态，火灾时当管道内气体温度达到280℃时自动关闭，在一定时间内能满足耐火稳定性和耐火完整性要求。起隔烟阻火作用的阀门。

Fire proof valve refers installed in the ventilation, air-conditioning systems to send, and the road back to the wind, opened in a state of fire when the temperature reached 70 degrees, the gas automatically closed in a certain period of time to meet the fire resistance requirements of the stability and integrity of fire resistance, a possible role of the fire fight valves. Smoke extraction fire fight valve refers smoke extraction system installed in the pipeline, in an open state of the gas pipeline fires when the temperature reached 280 degrees automatically closed in a certain period of time to meet the fire resistance stability and fire resistance integrity. A possible role valves smoke proof.

防火阀有两种，70度和280度，70度用于新风机，当温度到达70度时关闭新风机，证明已经着火了，再别进风了。当温度达到280度时，关闭排烟风机，要不然火会顺着风道烧到别的地方。 一、防火阀从温度划分：有70摄氏度和280摄氏度的。 二、防火阀从控制划分有手动的和DC24V电磁铁控制，即电动的； 三、防火阀从远近控制的有远程控制和本体控制的。

There are two kinds of fire proof valves , 70 degrees and 280 degrees, 70 degrees for the new air-compressors, when the temperature reached 70 degrees, the closure of the new air-compressors, has proven fire, another into the wind again. When the temperature reached 280 degrees, the closure of smoke extraction air-compressors, or else the fire will run wind Road reached elsewhere. 1, fire safe vavle from temperature divided : 70 degrees Celsius and 280 degrees Celsius. Second, from control by fire safe valve DC24V electro-magnet and a manual control, electric; 3, fire safe valve far from the control of the remote control and identity control.
