1、不锈钢螺旋风管、通风设备采用软连接三个织物阻燃材料,建议在15 - 30厘米,长度和电交叉应该结束。所有的螺栓要求相同的长度。
1. The stainless steel spiral air duct and ventilation equipment are made of three fabric flame retardant materials with soft connection. It is suggested that the length and electrical crossing should be ended at 15-30 cm. All bolts require the same length.
三个主体应该接地、通风设备、动态负载之间的设备和安装基础应配备减震措施。
The three main bodies should be grounded, ventilation equipment and dynamic load between equipment and installation foundation shall be equipped with shock absorption measures.
2、暴露了电源线必须穿线管、线管材料与金属软管或卡佩里和鸭脖子设备联合应该使它弯曲的水滴型,消防的消防系统和设备线必须有专用夹具是固定的,为了防止跌倒。
2, the power line must be exposed to the wire pipe, the wire tube material and the metal hose or the joint of the Capelli and the duck neck equipment which should bend it. The fire fighting system and the equipment line must have a special fixture to be fixed to prevent the fall.
3、防火阀用于压缩空气供应系统,通常使用70°防火阀、排气防火阀是280度。当烟雾和风力系统进气口和排气口垂直时,其高度不低于3米,安置的水平时,水平距离不得少于10米。
3, fire damper for compressed air supply system, usually using 70 degree fire damper, exhaust fire damper is 280 degrees. When the smoke and wind system inlet and outlet vertical, its height is not less than 3 meters, the placement of horizontal distance should not be less than 10 meters.
4、当通风管需要改变方向,可变直径,岔路,或汇不宜使用箱式管道配件,但必要时使用的气流分布与静压箱,箱形断面风速不应超过1.5 m / s;导管管之间的5 - 10倍管道直径是明智的,可伸缩的金属管道或非金属软链接不宜超过2米的长度,不应当有崩溃和死亡角落在安装过程中,管道弯头和直管长度超过20米添加反影响框架
4, when the ventilator needs to change direction, variable diameter, fork road, or not suitable for use of box type fittings, air distribution and static pressure box should not exceed 1.5 m / s when necessary; 5-10 times the diameter of pipe pipe is wise, and extensible metal pipe or non metal link should not exceed 2 meters long. There should be no collapse and death corner in the installation process, pipe elbow and straight pipe length more than 20 meters added anti impact framework.
地下室排气扇,加减支架。
The exhaust fan in the basement is added and reduced.
5、防火分区隔墙两侧的消防阀和墙面的间距应不大于20厘米,通过与金属管道与墙的厚度2 ~ 3毫米钢板。
5. The distance between the fire valve and the wall surface on both sides of the partition wall of the fire protection zone should not be more than 20 cm. The thickness of the fire valve and the wall should be 2-3 mm steel plate through the metal pipe.
6、锡通风管托根做防腐处理。
6, tin ventilation pipe root to do anticorrosion treatment.
7、通风风口处根据快门或净,风口安装上盖。
7. Install the upper cover according to the shutter or net and air outlet.
消防排烟管道系统中,机场和空气阀必须采用不燃材料,不当使用公民烟道、镀锌通风管的厚度高压系统标准GB50243选择。当消防排烟风机安装在屋顶上,应该有一定的保护措施。
In the fire and exhaust pipe system, the airport and air valve must be used uncombustible material, and the national standard GB50243 of the thickness and high pressure system of the citizen flue and galvanized pipe is not used properly. When fire-fighting smoke exhausting fan is installed on the roof, there should be some protective measures.
