通风管道是建筑物中用于空气或气体传输的系统，主要应用于内部通风、空调和排烟系统。其基本构成包括管道、弯头、三通等部件，材质涵盖金属（如镀锌钢板、铝板、不锈钢）和非金属（如玻璃钢、聚氯乙烯）。

Ventilation ducts are systems used in buildings for the transmission of air or gas, primarily for internal ventilation, air conditioning, and smoke exhaust systems. Its basic components include pipes, elbows, tees, and other parts, with materials ranging from metal (such as galvanized steel plates, aluminum plates, stainless steel) to non-metal (such as fiberglass, polyvinyl chloride).

通风管道的设计和安装需考虑建筑物结构、使用功能、人员密度和气候环境。设计阶段涉及确定需求、选择材料和布局规划；安装阶段包括准备工作、测量标记、主干管和分支管安装、检查调整以及验收测试，确保管道质量和安全性，避免漏风、震动等问题，最终实现通风管道系统的高效运行。

The design and installation of ventilation ducts need to consider building structure, functional use, personnel density, and climate environment. The design phase involves determining requirements, selecting materials, and layout planning; The installation phase includes preparation work, measurement marking, installation of main and branch pipes, inspection and adjustment, and acceptance testing to ensure the quality and safety of the pipeline, avoid problems such as air leakage and vibration, and ultimately achieve efficient operation of the ventilation duct system.

通风管道按外形分为圆形和矩形，按材质分为普通薄钢板、镀锌薄钢板、不锈钢板等。 通风管道的尺寸设计应根据风量要求和运行压力确定，直径或截面尺寸应满足设计要求。安装规范包括垂直或水平安装、密封连接、牢固支架等。

Ventilation ducts are divided into circular and rectangular shapes according to their appearance, and into ordinary thin steel plates, galvanized thin steel plates, stainless steel plates, etc. according to their materials. The size design of ventilation ducts should be determined based on the air volume requirements and operating pressure, and the diameter or cross-sectional size should meet the design requirements. Installation specifications include vertical or horizontal installation, sealed connections, and secure brackets.

For areas with high fire protection requirements or ventilation ducts that pass through fire compartments, fire-resistant materials such as fire-resistant rock wool, fire-resistant boards, etc. can be used to wrap the ducts to improve their fire resistance performance.

The installation of ventilation ducts also needs to comply with national and local standards, such as the "Code for Design of Building Ventilation and Air Conditioning", and develop detailed construction plans. During the installation process, it is necessary to ensure the sealing, stability, and fire resistance of the pipeline, and avoid excessive length or curvature.
