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(shuō)風(fēng)管管底標(biāo)高，還是標(biāo)高，還是頂標(biāo)高。所以在風(fēng)管之前，要看清圖紙上的風(fēng)管將來(lái)是上平齊，還是下平齊，還是齊，那相對(duì)應(yīng)的調(diào)整管底標(biāo)高，標(biāo)高和頂標(biāo)高。（此外，在做風(fēng)管轉(zhuǎn)化時(shí)，也要針對(duì)性的要使用對(duì)應(yīng)的一種）。通風(fēng)考慮的主要有風(fēng)口、風(fēng)管、風(fēng)閥、風(fēng)設(shè)備及一些附件。本次主要強(qiáng)調(diào)通風(fēng)系統(tǒng)中風(fēng)管和風(fēng)閥操作注意事項(xiàng)：

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(fēng)管轉(zhuǎn)化，這一步要輸入好以下方面：一是風(fēng)管的材質(zhì)，二是風(fēng)管的壁厚，三是風(fēng)管的接口型式，四是風(fēng)管的保溫厚度。這些參數(shù)更好看一下說(shuō)明，如果沒(méi)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(fēng)管道中風(fēng)閥的繪制及注意事項(xiàng)。關(guān)于風(fēng)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(shuō)一下風(fēng)閥中比較特殊的內(nèi)容。在管道里面，閥門是不扣減管道長(zhǎng)度的，但在風(fēng)管里面，風(fēng)閥是要扣減掉風(fēng)管的長(zhǎng)度的，對(duì)于不同的風(fēng)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.
