　　通风管道主要作用是用于输送和分布风量（空气） 。通风管按外形分为圆形和矩形。通风管除直管外， 还有弯头、天圆地方、变径弯， 三通、四通等管件组成。通风管道按材质分为普通薄钢板，镀锌薄钢板、不锈钢板、铝板等金属风管、硬聚氯乙烯塑料板、塑料复合钢板和玻璃钢风管等。风管保温有橡塑保温和玻璃棉保温，一般选用橡塑保温。

　　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.

　　通风管道工程概述通风管道是为了使空气流通，降低有害气体浓度的一种市政基础设施。通风管的制作与安装所用板材、型材以及其他主要成品材料，应符合设计及相关产品现行标准的规定，并应用出厂检验合格证明。

　　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.
