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. Stainless steel spiral air duct and ventilation equipment adopt soft connection three fabric flame retardant materials. It is recommended that the 15-30 cm length and electrical cross should end. 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 is perpendicular to the intake port and exhaust port, its height is not less than 3 meters, and the 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米添加反影响框架地下室排气扇,加减支架。

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. There should be no collapse and death corner in the installation process, pipe elbow and straight pipe length more than 20 meters add anti impact frame basement exhaust fan, plus and minus bracket.
