        通風系統中風管和風閥的注意事項!

        來源:http://www.boursomarket.com 日期:2019-07-30 發布人:admin

          在安裝計算中,有一個的暖通空調,其中通風系統是一個非常重要的環節。用通風系統說明操作方法及注意事項。
          In installation calculation, there is a professional HVAC, in which the ventilation system is a very important link. Use ventilation system to explain operation method and precautions.
          首先,通風系統的安裝計算有兩種方法,一種是繪圖法,另一種是改造法。這次針對的是轉換模式的應用。
          Firstly, there are two methods to calculate the installation of ventilation system, one is the drawing method, the other is the transformation method. This time it is aimed at the application of transformation mode.
          通風主要考慮風口、風管、閥門、風設備等一些配件。
          Ventilation specialty mainly considers some accessories such as tuyeres, ducts, valves, air equipment, etc.
          本次主要強調通風系統風管、風門運行中應注意的事項:
          This paper mainly emphasizes the matters needing attention in the operation of air duct and air valve of ventilation system.
          首先,風道的識別
          Firstly, the identification of airway
          在管道改造之前,有一件事必須弄清楚,那就是管道的標高。當使用高度調整命令查看時,結果有時會有所不同。這是因為管道的標高而管道是管道的中心標高。如果你在做導管,你會做得有點不同。比如管道的底部,或者中心,或者頂部。因此,在使用風管之前,要先看圖紙上的風管是頂部沖洗,底部沖洗還是中心沖洗,并相應地調整底部標高、中心標高和頂部標高。(此外,在做風管改造時,也應有針對性地使用相應的風管)。
          Before the pipeline transformation, one thing must be clear, that is, the pipeline elevation. When viewed with the height adjustment command, the results sometimes differ. This is because the elevation of the pipeline is the central elevation of the pipeline. If you're making a catheter, you'll do it a little differently. For example, the bottom of the pipe, or the center, or the top. Therefore, before using the air duct, it is necessary to see whether the air duct on the drawing is top flushed, bottom flushed or center flushed, and adjust the bottom elevation, center elevation and top elevation accordingly. (In addition, the corresponding ducts should also be used in the modification of ducts.

          現在我們要做好風管改造工作。在這一步中,我們需要輸入以下幾個方面:首先,風管的材質;二是風管壁厚;三是風管接口類型;四是風管保溫厚度。更好的方法是更好地查看這些參數。如果沒有,請參考05n4-3的相關規定。
          Now we need to do a good job in air duct renovation. In this step, we need to input the following aspects: firstly, the material of the duct; secondly, the wall thickness of the duct; thirdly, the type of duct interface; fourthly, the insulation thickness of the duct. A better way is to look at these parameters better. If not, please refer to the relevant provisions of 05n4-3.
          氣閥圖紙及注意事項
          Drawing of valve and matters needing attention
          關于風閥可以轉換,也可以直接繪制,該方法可參考轉換設備。這里說的風閥內容比較特殊。在管道主要,閥門不扣除管道的長度,但在風管中,風管閥門是扣除風管的長度,對于不同類型的風管閥門,有不同的扣除方法。如下圖所示,無論風管的寬度是多少,氣閥的扣緊量都是固定的;有些風管的寬度上有什么值,風門的長度扣固定加上風管的高度(或半徑);在另一種情況下,管道的寬度與閥門的長度相對應。我們可以根據具體要求選擇不同類型的氣閥。
          For the air valve can be converted or drawn directly, this method can refer to the conversion equipment. The contents of the air valve mentioned here are quite special. In the main pipeline, the valve does not deduct the length of the pipeline, but in the duct, the duct valve is deducted the length of the duct, for different types of duct valves, there are different deduction methods. As shown in the following figure, no matter how wide the duct is, the tightening of the valve is fixed; what is the value of the width of some ducts, the length of the duct is fixed and the height (or radius) of the duct is fixed; in another case, the width of the duct corresponds to the length of the valve. We can choose different types of valves according to specific requirements.
