The ventilation pipe plays an important role in life, and it plays an important role in helping air circulation. Linyi ventilation pipe manufacturer tells us how to reduce the resistance of ventilation pipe

1、通風管道設彎曲的角度要盡量呈弧形。

1. When designing the ventilation pipe, the bending angle should be as arc as possible.

2、通風管道設彎頭要盡量少，兩個彎頭的距離要大些。當兩個彎頭的距離為管徑的3倍時，阻力大約增加80%;若為5倍時，則僅增加30%。

2. In the design of ventilation duct, the elbows should be as few as possible, and the distance between the two elbows should be larger. When the distance between the two elbows is three times of the pipe diameter, the resistance increases about 80%; If it is 5 times, it will only increase by 30%.

3、盡量直立或傾斜放置，設置清掃口，連接部分應嚴密不漏氣，并便于檢修。

3. It shall be placed vertically or obliquely as far as possible, and the cleaning opening shall be set. The connection part shall be tight without air leakage and easy for maintenance.

4、所用材料應具有導熱性小、保溫，耐腐蝕、耐火等性能。

4. The materials used should have low thermal conductivity, thermal insulation, corrosion resistance, fire resistance and other properties.

5、通風管道設不宜太長，在可能條件下；管徑要粗，式樣以圓形為佳。

5. The ventilation duct should not be too long when it is designed, if possible; The pipe diameter should be thick, and the round shape is better.

6、支管的半徑不得小于主管半徑的1/2-1/3，便于通風管道加工。

6. The radius of the branch pipe shall not be less than 1 / 2-1 / 3 of the radius of the main pipe to facilitate the processing of the ventilation pipe.

通風管道系統巧妙設計可大大減少排氣阻力，使用效果也會更好，所以設計通風管道師要注意細節問題！

Ventilation duct system ingenious design can greatly reduce the exhaust resistance, the use effect will be better, so the designer of ventilation duct should pay attention to the details!
