    济南卷帘门设在疏散走道上的防火卷帘应在卷帘的两侧设置启闭装置,还要求具有机械控制的功能,所以防火卷帘还应加设温度熔断控制装置"虽然防火卷帘采用了双电源及多种控制方式,但如果发生火灾时电源被切断,防火卷帘就无法动作,虽然设有手动控制装置,但根据有关测试,一般民用建筑发生火灾时,烟气水平方向流动速度为0.3-0.8米/秒,垂直方向扩散速度为3-4米/秒,火灾发生时,只要人员不在卷帘附近,就很难手动操纵卷帘下降"为解决这个问题,
    Ji'nan rolling shutter door is arranged at the fire shutter evacuation aisle shall set up the opening and closing

    device in rolling on both sides, also require the machinery control function, so the fire shutter should also be

    adding a temperature fuse control device "although fire shutter adopts double power supply and a variety of control

    mode, but if a fire occurs when the power was cut off, fire shutter no movement, although a manual control device,

    but according to the relevant test, general civil construction fire occurs, smoke horizontal flow speed of 0.3-0.8 M

    / sec, vertical diffusion speed of 3-4 M / s, when a fire happens, as long as the personnel in the rolling nearby,

    it is difficult to manually manipulate the shutter down" to solve this problem,
        在防火卷帘上增设温度熔断控制装置,当发生火灾高温烟气到达卷帘处时,温度熔断控制装置动作,防火卷帘依靠自重下落关闭,阻隔火势蔓延"为使温控装置及时动作,在安装时应注意位置要选在能反映火情易检修并与感温感烟探头同高度的位置,并尽量靠近卷帘的传动装置;设在建筑物内相邻两个防火分区间的防火卷帘,其温控装置应两面安装,以确保无论哪个防火分区发生火灾时,防火卷帘都能及时动作。
    Adding a temperature fuse control device in the fire shutter, when fire reaches the shutter at the high temperature

    flue gas, the temperature fuse control the movement of the device, fire shutter by the weight fall off, blocking the

    spread of fire "for the temperature control device to enable the timely action, in the installation should pay

    attention to the position to be elected in the most can reflect the fire easy maintenance and temperature smoke

    probe the same height position, transmission device and as close as possible to the shutter; located in the fire

    roller shutter buildings adjacent two fire partition between the two sides, temperature control device should be

    installed, to ensure that no matter which fire compartment fires, fire shutter can timely action.
