我們都知道，凡事都應(yīng)該具體問題具體分析，在通風(fēng)管道設(shè)計時也是一樣的，通風(fēng)管道設(shè)計結(jié)合實際。有朋友就要問了，通風(fēng)管道直接買現(xiàn)成的通用就好了，為什么還要分別設(shè)計呢?今天，小編就給大家分析通風(fēng)管道設(shè)計結(jié)合實際的原因，希望可以幫助大家。

　　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.蒸汽或其他含水的氣體管道在低點設(shè)置排水管或疏水閥，某些通風(fēng)管道還設(shè)有氣水分離器，以便及時排去水液，防止管內(nèi)產(chǎn)生水擊和阻礙氣體流動。通風(fēng)管道設(shè)計時為了排除凝結(jié)水，蒸汽和其他含水的氣體管道應(yīng)有一定的坡度，一般不小于千分之二。對于利用重力流動的地下排水管道，坡度不小于千分之五。給水或其他液體管道在高點設(shè)有排氣裝置，排除積存在管道內(nèi)的空氣或其他氣體，以防止氣阻造成運行失常。

　　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.地面上的管道應(yīng)盡量避免與道路、鐵路和航道交叉。在不能避免交叉時，交叉處跨越的高度也應(yīng)能使行人和車船通過。通風(fēng)管道設(shè)計時地下的管道一般沿道路敷設(shè)，各種管道之間保持適當(dāng)?shù)木嚯x，以便安裝和維修。

　　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.通風(fēng)管道加工時為了保證管道的強度和剛度，設(shè)置各種支(吊)架，如活動支架、固定支架、導(dǎo)向支架和彈簧支架等。支架的設(shè)置根據(jù)管道的直徑、材質(zhì)、管子壁厚和載荷等條件決定。

　　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.
