随着经济的快速发展，通风管道在生活中的用处越来越大。比如在餐厅，通风设备为消费者提供了良好的就餐环境，让人们在餐厅吃得开心。下面来看看
济南通风管道设计中应该注意的要点。
With the rapid development of economy, ventilation ducts are more and more useful in life. For example, in restaurants, ventilation equipment provides consumers with a good dining environment, allowing people to eat happily in restaurants. Now let's take a look at the key points that should be paid attention to in the design of Jinan ventilation pipeline.
一、先是应按某系统的某楼层通风管道进行绘制，并注明接口位置。
1、 Firstly, it shall be drawn according to the ventilation pipe of a certain floor of a system, and the interface position shall be indicated.
二、通风管道设计应进行编号，从起点开始编号，起点一般为接口位置，相同断面规格、相同长度节为同一号码，除此应按顺序编号。以便于组织制作施工。
2、 The design of ventilation ducts shall be numbered from the starting point. The starting point is generally the interface position, and the same section specification and length section are the same number. In addition, they shall be numbered in sequence. To facilitate the organization of fabrication and construction.
三、通风管道设计要标记支吊架位置，支吊架位置间距及材料规格要符后规范要求及工艺规定。
3、 The position of supports and hangers shall be marked in the design of ventilation ducts, and the spacing between supports and hangers and the material specifications shall conform to the following specification requirements and process regulations.
四、制作通风管道设应先考量弯头与变径满足内外表面同心弯管要求、变径长度要求。
4、 The elbow and reducer shall meet the requirements of inner and outer concentric elbow and reducer length when designing the ventilation duct.
五、通风管道设计应标记起端与弯头位置、变径位置、管线所处轴线位置、管底标高。
5、 The position of the starting end and elbow, the reducing position, the axis position of the pipeline and the elevation of the pipe bottom shall be marked in the ventilation pipe design.
此外对充分的准备工作是确保风管安装质量的前提。在准备净化风管的制作时，无论是采取工厂集中制作还是现场制作方式，都保证场地的洁净和封闭，并拥有符合条件的采光和照明条件。除此外，还要对制作好的方管进行看管，尽量避免污染。
In addition, adequate preparation is the premise to ensure the installation quality of air duct. When preparing for the production of purified air duct, whether centralized production in the factory or on-site production is adopted, the site shall be clean and closed, and have qualified lighting and lighting conditions. In addition, the fabricated square tube shall be watched to avoid pollution as much as possible.
The prefabricated air duct shall be stored well to avoid secondary pollution. Before using the air duct, pay attention to the cleaning work to ensure that the surface of the plate is free of corrosion and does not absorb dust after drying.
