专注通风管道加工·排烟罩

我们都知道，凡事都应该具体问题具体分析，在通风管道设计时也是一样的，通风管道设计结合实际。有朋友就要问了，通风管道直接买现成的通用就好了，为什么还要分别设计呢?今天，小编就给大家分析通风管道设计结合实际的原因，希望可以帮助大家。

　　As we all know, everything should be analyzed in detail. The same is true in the design of ventilation ducts. The design of ventilation ducts should be combined with practice. A friend will ask, ventilation pipes directly buy ready-made general, why should they be designed separately? Today, Xiaobian will give you an analysis of ventilation pipes design combined with practical reasons, hoping to help you.

　　1.蒸汽或其他含水的气体管道在低点设置排水管或疏水阀，某些通风管道还设有气水分离器，以便及时排去水液，防止管内产生水击和阻碍气体流动。通风管道设计时为了排除凝结水，蒸汽和其他含水的气体管道应有一定的坡度，一般不小于千分之二。对于利用重力流动的地下排水管道，坡度不小于千分之五。给水或其他液体管道在高点设有排气装置，排除积存在管道内的空气或其他气体，以防止气阻造成运行失常。

　　1. Steam or other water-bearing gas pipes are equipped with drainage pipes or traps at low points, and some ventilation pipes are equipped with air-water separators to drain water in time to prevent water hammer and obstruct gas flow in pipes. In order to exclude condensate water, steam and other water-bearing gas pipelines should have a certain gradient in the design of ventilation pipelines, generally not less than two thousandths. For underground drainage pipelines using gravity flow, the slope is not less than five thousandths. Feed water or other liquid pipes are equipped with exhaust devices at high points to remove air or other gases accumulated in the pipes, so as to prevent air resistance from causing abnormal operation.

　　2.地面上的管道应尽量避免与道路、铁路和航道交叉。在不能避免交叉时，交叉处跨越的高度也应能使行人和车船通过。通风管道设计时地下的管道一般沿道路敷设，各种管道之间保持适当的距离，以便安装和维修。

　　2. Pipelines on the ground should avoid crossing roads, railways and waterways as far as possible. When crossing is unavoidable, the crossing height should also enable pedestrians and vehicles to pass through. When designing ventilation pipelines, underground pipelines are generally laid along roads, and proper distances between various pipelines are maintained for installation and maintenance.

　　3.通风管道加工时为了保证管道的强度和刚度，设置各种支(吊)架，如活动支架、固定支架、导向支架和弹簧支架等。支架的设置根据管道的直径、材质、管子壁厚和载荷等条件决定。

　　3. In order to ensure the strength and stiffness of the ventilation pipeline, a variety of brackets (suspension) are set up, such as movable bracket, fixed bracket, guide bracket and spring bracket. The bracket is set according to the pipe diameter, material, pipe wall thickness and load conditions.
