防火卷帘门广泛应用于工业与民用建筑的防火隔断区，能有效地阻止火势蔓延，保障生命财产，是现代建筑中不可或缺的防火设施。那么防火卷帘门作为防火设施使用时了解什么？

Fire resisting rolling shutter doors are widely used in the fire partition area of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. What do you know about the use of fire rolling doors as fire prevention facilities?

防火卷帘的组成部分包括帘板、滚筒、托架、导轨和控制机构，组合体有封闭在滚筒内的运转平衡器、自动关闭机构、金属罩及帘板等几个部分。

The components of the fireproof roller shutter include the shutter, roller, bracket, guide rail and control mechanism. The assembly consists of a running balancer enclosed in the roller, an automatic closing mechanism, a metal cover and a shutter.

防火卷帘门是在钢质卷帘的基础上，将传动部件加以改造，配以防火电器等设备，从而实现防火作用：防火电机由防火电控箱控制，通过变速装置驱动卷轴使卷帘门起闭，停电时也可使用防火电机上的手动摇柄，可实现手动操作。

The fireproof rolling shutter door is based on the steel rolling shutter, and the transmission parts are modified, equipped with fireproof electrical appliances and other equipment, so as to achieve the fireproof effect: the fireproof motor is controlled by the fireproof electric cabinet, and the roller is driven by the speed change device to open and close the rolling shutter door. When the power is cut off, the manual handle on the fireproof motor can also be used to achieve manual operation.

在机械相对运动处，采用联轴器代替链轮传动，道轨内摩擦处镶嵌铜板或尼龙。适合于使用或保管可燃性气体、挥发性化学药品等具有高发火性物品的工厂和仓库等出现或可能出现爆炸的火灾危险的环境。

At the relative movement of the machinery, the coupling is used to replace the sprocket drive, and the friction in the track is inlaid with copper plate or nylon. It is suitable for the use or storage of flammable gases, volatile chemicals and other highly inflammable materials in factories and warehouses where there is or may be an explosion of fire hazards.

另外，防火卷帘在设置方面有如下要求：

In addition, the following requirements are required for the setting of fire shutter:

如果耐火极限符合《门和卷帘的耐火试验方法》GB/T7633里有关耐火完整性和耐火隔热性判定条件的标准，防火卷帘可不设置自动喷水灭火系统保护。

If the fire resistance limit complies with the national standards for judging conditions of fire integrity and fire resistance and thermal insulation in Fire Resistance Test Methods for Doors and Shutters (GB/T7633), the fire shutter may not be protected by an automatic sprinkler system.

如果耐火极限仅符合现行标准《门和卷帘的耐火试验方法》GB/T7633有关耐火完整性的标准判定条件，但不符合耐火隔热性判定条件，则防火卷帘应设置自动喷水灭火系统保护。

If the fire resistance limit only conforms to the current national standard Fire Resistance Test Method for Doors and Shutters (GB/T7633), but does not conform to the judgment conditions of fire resistance and thermal insulation, the fire shutter shall be protected by an automatic sprinkler system.
