1、不銹鋼螺旋風(fēng)管、通風(fēng)設(shè)備采用軟連接三個(gè)織物阻燃材料,建議在15 - 30厘米,長(zhǎng)度和電交叉應(yīng)該結(jié)束。所有的螺栓要求相同的長(zhǎng)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.

三個(gè)主體應(yīng)該接地、通風(fēng)設(shè)備、動(dòng)態(tài)負(fù)載之間的設(shè)備和安裝基礎(chǔ)應(yīng)配備減震措施。

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、暴露了電源線必須穿線管、線管材料與金屬軟管或卡佩里和鴨脖子設(shè)備聯(lián)合應(yīng)該使它彎曲的水滴型,消防的消防系統(tǒng)和設(shè)備線必須有專用夾具是固定的,為了防止跌倒。

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、防火閥用于壓縮空氣供應(yīng)系統(tǒng),通常使用70°防火閥、排氣防火閥是280度。當(dāng)煙霧和風(fēng)力系統(tǒng)進(jìn)氣口和排氣口垂直時(shí),其高度不低于3米,安置的水平時(shí),水平距離不得少于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、當(dāng)通風(fēng)管需要改變方向,可變直徑,岔路,或匯不宜使用箱式管道配件,但必要時(shí)使用的氣流分布與靜壓箱,箱形斷面風(fēng)速不應(yīng)超過(guò)1.5 m / s;導(dǎo)管管之間的5 - 10倍管道直徑是明智的,可伸縮的金屬管道或非金屬軟鏈接不宜超過(guò)2米的長(zhǎng)度,不應(yīng)當(dāng)有崩潰和死亡角落在安裝過(guò)程中,管道彎頭和直管長(zhǎng)度超過(guò)20米添加反影響框架

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.

地下室排氣扇,加減支架。

The exhaust fan in the basement is added and reduced.

5、防火分區(qū)隔墻兩側(cè)的消防閥和墻面的間距應(yīng)不大于20厘米,通過(guò)與金屬管道與墻的厚度2 ~ 3毫米鋼板。

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、錫通風(fēng)管托根做防腐處理。

6, tin ventilation pipe root to do anticorrosion treatment.

7、通風(fēng)風(fēng)口處根據(jù)快門(mén)或凈,風(fēng)口安裝上蓋。

7. Install the upper cover according to the shutter or net and air outlet.

消防排煙管道系統(tǒng)中,機(jī)場(chǎng)和空氣閥必須采用不燃材料,不當(dāng)使用公民煙道、鍍鋅通風(fēng)管的厚度高壓系統(tǒng)標(biāo)準(zhǔn)GB50243選擇。當(dāng)消防排煙風(fēng)機(jī)安裝在屋頂上,應(yīng)該有一定的保護(hù)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.
