1、 Identification of air duct

关于风管加工的转化之前，有一个内容要求先清楚，那就是关于风管的标高。用高度调整指令检查时，有时显示出来的效果不一样。那是由于，管线和管道的标高就是线或管的中间标高，往常再说管道多高时，就是把管道当作一根线。而假定做风管，那在标明标高时，办法就有些不同。要说风管管底标高，仍是中间标高，仍是顶标高。所以在风管之前，要看清图纸上的风管将来是上平齐，仍是下平齐，仍是中间齐，那相对应的调整管底标高，中间标高和顶标高。（此外，在做风管转化时，也要针对性的要运用对应的一种）。

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).

那现在要做好风管转化，这一步要输入好以下方面：一是风管的材料，二是风管的壁厚，三是风管的接口型式，四是风管的保温厚度。这些参数看一下阐明，假定没有的话参看05N4-3的相关规定。

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、风阀的制作及注意事项

2、 Fabrication and precautions of air valve

关于风阀能够用转化，也能够直接制作，办法能够参看转化设备。这儿说一劣势阀中比较特别的内容。在管道里边，阀门是不扣减管道长度的，但在风管里边，风阀是要扣减掉风管的长度的，关于不同的风阀类型，有不同的扣减办法。还有一种状况，风管的宽度与风阀的长度有一个对应联络。咱们能够依据具体的阐明来挑选不同的风阀类别。

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.

通风体系中风管和风阀操作注意事项

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

石家庄通风管道，在进行通风工程时，我们应注意以下六大事项：

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

①下料时应使用不产生划痕的画线工具，操作时应使用木捶或有胶皮套的锤子，不得使用铁锤，以免落锤点产生锈斑

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通风工程的搬运装卸应轻拿轻放，防止损坏成品

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

③风口成品应采取防护措施，保护装饰面不受损伤

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

④法兰用料分类理顺码放，露天放置应采取防雨、雪措施，减少生锈现象

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不锈钢板、铝板要立靠在木架上、不要平迭，以免拖动时刮伤表面

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通风工程所需材料应码放在平整，无积水，宽敞的场地，不与其它材料，设备等码放在一起，并有防雨、雪措施，码放时应按系统编号，整齐、合理，便于装运。

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.
