        通風系統中風管和風閥操作注意事項!

        來源:http://www.boursomarket.com 日期:2019-10-10 發布人:admin

          在安裝計算中,有一個專門針對HVAC的系統,其中通風系統是HVAC的重要組成部分。 讓我說說通風系統的操作方法和注意事項。
          In installation calculation, there is a special system for HVAC, and ventilation system is an important part of HVAC. Let me talk about the operation method and precautions of the ventilation system.
          首先,通風系統在安裝計算中有兩種方法,一種是繪圖法,另一種是轉換法。 這次,談談轉換方法的應用。
          Firstly, there are two methods in installation calculation of ventilation system, one is drawing method, the other is conversion method. This time, talk about the application of conversion methods.
          通風考慮因素主要包括風口,風道,風門,風力設備和一些配件。
          The major considerations of ventilation include air outlets, air ducts, air doors, wind power equipment and some accessories.
          這次主要強調通風系統中風管和風門的操作注意事項:
          Emphasis is placed on the operation of air ducts and air doors in the ventilation system.
          一,風管的識別
          1. Identification of air ducts
          在轉換管道之前,必須有明確的內容,即管道的高度。 使用高度調整命令查看時,有時顯示的結果會有所不同。 那是因為管道和管道的標高是管道或管道的中心標高。 當管道很高時,它就是管道。 如果使用風管,則指示高程時方法會有所不同。 據說管道的底部是高程,或者是中心高程,或者是高海拔。 因此,在導風管之前,有必要查看圖紙上的導風管是否平齊或中心齊平,并相應調整管的底部高度,中心高度和頂部高度。  (此外,在進行風管轉換時,還必須使用相應的風管)。
          Before switching the pipeline, there must be a clear content, that is, the height of the pipeline. When viewed with the height adjustment command, sometimes the results will be different. That's because the elevation of pipes and pipes is the central elevation of pipes or pipes. When the pipe is very high, it is the pipe. If air duct is used, the method of indicating elevation will be different. It is said that the bottom of the pipeline is the elevation, or the central elevation, or the highest elevation. Therefore, before the duct, it is necessary to check whether the duct on the drawing is even or the center is even, and adjust the bottom height, the center height and the top height of the duct accordingly. (In addition, the corresponding duct must be used when the duct conversion is carried out).

          現在有必要做好風管轉換。 此步驟應輸入以下方面:一個是管道的材料,另一個是管道的壁厚,第三個是管道的界面類型,第四個是管道的絕緣厚度。 好查看這些參數的說明,否則請參見05N4-3的相關規定。
          Now it is necessary to do a good job of air duct conversion. This step should input the following aspects: one is the material of the pipe, the other is the wall thickness of the pipe, the third is the interface type of the pipe, and the fourth is the insulation thickness of the pipe. It is better to see the description of these parameters, otherwise please refer to the relevant provisions of 05N4-3.
          二,風閥的起草及注意事項
          2. Drafting of air valves and matters needing attention
          關于阻尼器,它可以轉換或直接繪制。 該方法可以參考轉換設備。 這里談談風門的特殊內容。 在管道行業中,閥門并沒有扣除管道的長度,但是在管道中,阻尼器就是要減少管道的長度。 對于不同類型的阻尼器,有不同的推導方法。 如下圖所示,某些風管寬度無論是什么值,風門僅屈曲一個固定值; 一些是風道寬度,風門的長度是固定的,風道的高度(或半徑)的值; 管道的寬度與風門的長度相對應。 我們可以根據具體說明選擇不同的風門類別。
          With respect to dampers, they can be converted or drawn directly. This method can refer to the conversion equipment. Here we talk about the special content of the damper. In the pipeline industry, the valve does not deduct the length of the pipeline, but in the pipeline, the damper is to reduce the length of the pipeline. There are different deduction methods for different types of dampers. As shown in the figure below, some duct widths, no matter what, buckle only a fixed value; some are duct widths, the length of the duct is fixed, the height (or radius) of the duct; the width of the duct corresponds to the length of the duct. We can choose different types of throttle according to the specific instructions.
