山東通風管道加工要做好風管轉化，這一步要輸入好以下方面：一是風管的材質，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。這些參數好看一下說明，如果沒有的話參考05N4-3的相關規定。

　　To do the transformation of the air pipe, this step should input the following aspects: one is the material of the wind pipe, two is the wall thickness of the air pipe, three is the interface type of the air pipe, and the four is the insulation thickness of the air pipe. These parameters are the best to look at that, if not the reference of the relevant provisions of 05N4-3.

　　對于風管的轉化之前，有一個內容必須要先明確，那就是關于風管的標高。用高度調整命令查看時，有時顯示出來的結果不一樣。那是因為，管線和管道的標高就是線或管的中心標高，平時再說管道多高時，就是把管道看成一根線。

　　Before the conversion wind pipe, a content must be clear, it is about the elevation of the wind pipe. Command view height adjustment, sometimes show different results. That is because the elevation of the pipeline and pipeline is the central elevation of the line or pipe, and the pipeline is usually regarded as a line when the pipeline is too high.

　　而如果做風管，那在表示標高時，方法就有些不同。要說風管管底標高，還是中心標高，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，還是中心齊，那相對應的調整管底標高，中心標高和頂標高。(此外，在做風管轉化時，也要針對性的要使用對應的一種)。

　　And if you do it in the wind, said the elevation when the method is somewhat different. To say the wind pipe bottom elevation, or center elevation, or top elevation. So before the wind pipe, to see the drawings on the wind pipe in the future is flat, or down flat, or the center of Qi, the corresponding adjustment of the pipe bottom elevation, central elevation and top elevation. (in addition, in the wind pipe transformation, but also to the one to use the corresponding).

　　關于風閥可以用轉化，也可以直接繪制，方法可以參考轉化設備。這里說一下風閥中比較特殊的內容。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。

　　The air valve can be used, can also direct rendering methods can refer to conversion equipment. Here said the special content in the wind valve. In the pipeline profession, the valve does not deduct the length of the pipe, but in the air pipe, the air valve is to deduct the length of the air duct, for different types of air valve, there are different methods of deduction.

　　有的是風管寬度不論什么值，風閥只扣一個固定值;有的是風管寬度論什么值，風閥長度扣固定加上風管的高度(或半徑);還有一種情況，風管的寬度與風閥的長度有一個對應關系。我們可以根據具體的說明來選擇不同的風閥類別。

　　There is no matter what the value of the width of duct, air valve buckle only a fixed value; some duct width on what values of air valve length fixing wind pipe height (or radius); there is a situation, there is a corresponding relationship between the width and the length of the air valve duct. We can choose different categories of air valve according to the specific instructions.
