一、風管的識別：對于風管的轉(zhuǎn)化之前，有一個內(nèi)容必須要先明確，那就是關(guān)于風管的標高。用高度調(diào)整命令查看時，有時顯示出來的結(jié)果不一樣。那是因為，管線和管道的標高就是線或管的標高，平時再說管道多高時，就是把管道看成一根線。而如果做風管，那在表示標高時，方法就有些不同。
1. Identification of duct: Before the transformation of duct, there must be a clear content, that is, the elevation of duct. When viewed with height adjustment commands, sometimes the results are different. That's because the elevation of pipelines and pipes is the central elevation of the line or pipe, usually say how high the pipe, is to regard the pipe as a line. If the duct is made, the method is somewhat different when it indicates the elevation.
要說風管管底標高，還是標高，還是頂標高。所以在風管之前，要看清圖紙上的風管將來是上平齊，還是下平齊，還是齊，那相對應(yīng)的調(diào)整管底標高，標高和頂標高。（此外，在做風管轉(zhuǎn)化時，也要針對性的要使用對應(yīng)的一種）。通風考慮的主要有風口、風管、風閥、風設(shè)備及一些附件。本次主要強調(diào)通風系統(tǒng)中風管和風閥操作注意事項：
The height of the bottom of the wind pipe is either the center elevation or the top elevation. So before the duct, it is necessary to see clearly whether the duct on the drawing will be uniform in the future, or even in the bottom, or even in the center, which corresponds to the adjustment of the pipe bottom elevation, center elevation and top elevation. (in addition, when the duct is transformed, the corresponding one should be used accordingly. The main consideration of ventilation is tuyere, wind pipe, air valve, wind equipment and some accessories. This article mainly emphasizes the matters needing attention in the operation of the ventilation system and the wind valve.
那現(xiàn)在要做好風管轉(zhuǎn)化，這一步要輸入好以下方面：一是風管的材質(zhì)，二是風管的壁厚，三是風管的接口型式，四是風管的保溫厚度。這些參數(shù)更好看一下說明，如果沒有的話參考05N4-3的相關(guān)規(guī)定。
Now we must do a good job of air duct conversion, this step to input the following aspects: first, the material of the air duct, second, the wall thickness of the air duct, third, the interface type of the air duct, fourth, the insulation thickness of the air duct. These parameters should be taken into account. If not, refer to the relevant regulations of 05N4-3.
二、通風管道中風閥的繪制及注意事項。關(guān)于風閥可以用轉(zhuǎn)化，也可以直接繪制，方法可以參考轉(zhuǎn)化設(shè)備。這里說一下風閥中比較特殊的內(nèi)容。在管道里面，閥門是不扣減管道長度的，但在風管里面，風閥是要扣減掉風管的長度的，對于不同的風閥類型，有不同的扣減方法。
Two. Drawing and notice of ventilation valve. The wind valve can be transformed or directly drawn. The method can refer to the transformation equipment. Here is a special description of the wind valve. In the pipeline profession, the valve does not deduct the length of the pipe, but in the duct, the air valve is to deduct the length of the duct, for different types of air valve, there are different deduction methods.
