详细介绍

      安装在通风、空气调节系统的送、回风管道上,平时呈开启状态,火灾时当管道内烟气温度达到70°C时关闭,并在一定时间内能满足漏烟量和耐火完整性要求,起隔烟阻火作用的阀门。

      防火阀一般由阀体、叶片、执行机构和温感器等组成。

      排烟防火阀 fire damper in smoke-venting system

      安装在机械排烟系统的管道上,平时呈开启状态,火灾时当排烟管道内烟气温度达到280°C时关闭,并在一定时间内能满足漏烟量和耐火完整性要求,起隔烟阻火作用的阀门。

      排烟防火阀一般由阀体、叶片、执行机构和温感器等部件组成。

      排烟阀 smoke damper

      安装在机械排烟系统各支管端部(烟气吸入口)处,平时呈关闭状态并满足漏风量要求,火灾或需要排烟时手动和电动打开,起排烟作用的阀门。带有装饰口或进行过装饰处理的阀门称为排烟口。

      排烟阀一般由阀体、叶片、执行机构等部件组成。

It is installed on the supply and return air ducts of ventilation and air conditioning system. It is usually open and closed when the flue gas temperature in the duct reaches 70°C in case of fire. It can meet the requirements of smoke leakage and fireproof integrity within a certain period of time and play the role of smoke isolation and fire resistance valve.

Fire valve is generally composed of valve body, blade, actuator and temperature sensor.

Fire Exhaust fire valve in smoke- disconnects System

It is installed on the pipe of the mechanical smoke exhaust system and is normally open. In case of fire, it will be closed when the smoke temperature in the smoke exhaust pipe reaches 280°C. It can meet the requirements of smoke leakage and fire-resistance integrity within a certain period of time and play the role of smoke isolation and fire resistance valve.

Smoke exhaust fire valve is generally composed of body, blade, actuator and temperature sensor.

Exhaust valve Smoke Damper

It is installed at the end of each branch pipe of the mechanical smoke exhaust system (smoke intake). It is usually closed and meets the requirements of air leakage. In case of fire or smoke exhaust, it can be opened manually or electrically to play the role of smoke exhaust. A valve with a decorative or decorative finish is called a smoke vent.

Exhaust valve is generally composed of valve body, blade, actuator and other components.
