　　通風(fēng)管道主要作用是用于輸送和分布風(fēng)量（空氣） 。通風(fēng)管按外形分為圓形和矩形。通風(fēng)管除直管外， 還有彎頭、天圓地方、變徑彎， 三通、四通等管件組成。通風(fēng)管道按材質(zhì)分為普通薄鋼板，鍍鋅薄鋼板、不銹鋼板、鋁板等金屬風(fēng)管、硬聚氯乙烯塑料板、塑料復(fù)合鋼板和玻璃鋼風(fēng)管等。風(fēng)管保溫有橡塑保溫和玻璃棉保溫，一般選用橡塑保溫。

　　The main function of ventilation ducts is to transport and distribute air volume (air). Ventilation ducts are divided into circular and rectangular shapes according to their appearance. In addition to straight pipes, ventilation ducts also consist of fittings such as elbows, roundabouts, variable diameter bends, tees, and crosses. Ventilation ducts are divided into ordinary thin steel plates, galvanized thin steel plates, stainless steel plates, aluminum plates and other metal ducts, rigid polyvinyl chloride plastic plates, plastic composite steel plates, and fiberglass ducts according to their materials. There are rubber insulation and glass wool insulation for air ducts, and rubber insulation is generally used.

　　通風(fēng)管道工程概述通風(fēng)管道是為了使空氣流通，降低有害氣體濃度的一種市政基礎(chǔ)設(shè)施。通風(fēng)管的制作與安裝所用板材、型材以及其他主要成品材料，應(yīng)符合設(shè)計及相關(guān)產(chǎn)品現(xiàn)行標(biāo)準(zhǔn)的規(guī)定，并應(yīng)用出廠檢驗(yàn)合格證明。

　　Overview of Ventilation Duct Engineering Ventilation ducts are a type of municipal infrastructure designed to facilitate air circulation and reduce the concentration of harmful gases. The plates, profiles, and other main finished materials used in the production and installation of ventilation ducts shall comply with the current national standards for design and related products, and shall be accompanied by factory inspection certificates.
