通風(fēng)管道是建筑物中用于空氣或氣體傳輸?shù)南到y(tǒng)，主要應(yīng)用于內(nèi)部通風(fēng)、空調(diào)和排煙系統(tǒng)。其基本構(gòu)成包括管道、彎頭、三通等部件，材質(zhì)涵蓋金屬（如鍍鋅鋼板、鋁板、不銹鋼）和非金屬（如玻璃鋼、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).

通風(fēng)管道的設(shè)計和安裝需考慮建筑物結(jié)構(gòu)、使用功能、人員密度和氣候環(huán)境。設(shè)計階段涉及確定需求、選擇材料和布局規(guī)劃；安裝階段包括準(zhǔn)備工作、測量標(biāo)記、主干管和分支管安裝、檢查調(diào)整以及驗收測試，確保管道質(zhì)量和安全性，避免漏風(fēng)、震動等問題，最終實現(xiàn)通風(fēng)管道系統(tǒng)的高效運行。

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.

通風(fēng)管道按外形分為圓形和矩形，按材質(zhì)分為普通薄鋼板、鍍鋅薄鋼板、不銹鋼板等。 通風(fēng)管道的尺寸設(shè)計應(yīng)根據(jù)風(fēng)量要求和運行壓力確定，直徑或截面尺寸應(yīng)滿足設(shè)計要求。安裝規(guī)范包括垂直或水平安裝、密封連接、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.
