1、 Identification of air duct

關于風管加工的轉化之前，有一個內容要求先清楚，那就是關于風管的標高。用高度調整指令檢查時，有時顯示出來的效果不一樣。那是由于，管線和管道的標高就是線或管的中間標高，往常再說管道多高時，就是把管道當作一根線。而假定做風管，那在標明標高時，辦法就有些不同。要說風管管底標高，仍是中間標高，仍是頂標高。所以在風管之前，要看清圖紙上的風管將來是上平齊，仍是下平齊，仍是中間齊，那相對應的調整管底標高，中間標高和頂標高。（此外，在做風管轉化時，也要針對性的要運用對應的一種）。

Before the conversion of air duct processing, there is a requirement to be clear about the elevation of air duct. When checking with the height adjustment command, sometimes the effect is different. That's because the elevation of pipeline and pipeline is the middle elevation of line or pipe. When we talk about how high the pipeline is, we treat the pipeline as a line. Assuming that the air duct is made, the method is somewhat different when indicating the elevation. The bottom elevation of the air duct is still the middle elevation and the top elevation. Therefore, before the air duct, it is necessary to see whether the air duct on the drawing is flush up, flush down or flush in the middle in the future. The corresponding adjustment of pipe bottom elevation, middle elevation and top elevation. (in addition, when converting the air duct, the corresponding one should also be used).

那現在要做好風管轉化，這一步要輸入好以下方面：一是風管的材料，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。這些參數看一下闡明，假定沒有的話參看05N4-3的相關規定。

Now we should do a good job in the transformation of air duct. In this step, we should input the following aspects: first, the material of air duct, second, the wall thickness of air duct, third, the interface type of air duct, and fourth, the insulation thickness of air duct. If these parameters are not available, please refer to the relevant provisions of 05n4-3.

二、風閥的制作及注意事項

2、 Fabrication and precautions of air valve

關于風閥能夠用轉化，也能夠直接制作，辦法能夠參看轉化設備。這兒說一劣勢閥中比較特別的內容。在管道里邊，閥門是不扣減管道長度的，但在風管里邊，風閥是要扣減掉風管的長度的，關于不同的風閥類型，有不同的扣減辦法。還有一種狀況，風管的寬度與風閥的長度有一個對應聯絡。咱們能夠依據具體的闡明來挑選不同的風閥類別。

The air valve can be converted or made directly. For the method, please refer to the conversion equipment. Let's talk about a special content in this article. In the pipeline, the valve does not deduct the length of the pipeline, but in the air duct, the air valve should deduct the length of the air duct. There are different deduction methods for different air valve types. In another case, there is a corresponding connection between the width of the air duct and the length of the air valve. We can select different types of air valves according to specific instructions.

通風體系中風管和風閥操作注意事項

Precautions for operation of air duct and air valve in ventilation system

石家莊通風管道，在進行通風工程時，我們應注意以下六大事項：

During the ventilation project of Shijiazhuang ventilation pipeline, we should pay attention to the following six matters:

①下料時應使用不產生劃痕的畫線工具，操作時應使用木捶或有膠皮套的錘子，不得使用鐵錘，以免落錘點產生銹斑

① During blanking, a line drawing tool without scratch shall be used. During operation, a wooden hammer or a hammer with rubber sleeve shall be used, and an iron hammer shall not be used to avoid rust spots at the drop point

②通風工程的搬運裝卸應輕拿輕放，防止損壞成品

② The handling, loading and unloading of ventilation works shall be handled with care to prevent damage to finished products

③風口成品應采取防護措施，保護裝飾面不受損傷

③ Protective measures shall be taken for the finished products of the air outlet to protect the decorative surface from damage

④法蘭用料分類理順碼放，露天放置應采取防雨、雪措施，減少生銹現象

④ Flange materials shall be classified and stacked in order. Rain and snow proof measures shall be taken for outdoor placement to reduce rust

⑤不銹鋼板、鋁板要立靠在木架上、不要平迭，以免拖動時刮傷表面

⑤ Stainless steel plate and aluminum plate shall stand against the wooden frame and shall not be stacked horizontally to avoid scratching the surface during dragging

⑥通風工程所需材料應碼放在平整，無積水，寬敞的場地，不與其它材料，設備等碼放在一起，并有防雨、雪措施，碼放時應按系統編號，整齊、合理，便于裝運。

⑥ The materials required for ventilation works shall be stacked in a flat, free of ponding and spacious site, not together with other materials and equipment, and rain and snow prevention measures shall be taken. The stacking shall be orderly and reasonable according to the system number for easy shipment.
