通风管道中风阀及风管的注意事项

来源: 日期:2020-07-22 发布人:gaoshitongferng

一、风管的识别:对于风管的转化之前,有一个内容必须要先明确,那就是关于风管的标高。用高度调整命令查看时,有时显示出来的结果不一样。那是因为,管线和管道的标高就是线或管的标高,平时再说管道多高时,就是把管道看成一根线。而如果做风管,那在表示标高时,方法就有些不同。
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.
要说风管管底标高,还是标高,还是顶标高。所以在风管之前,要看清图纸上的风管将来是上平齐,还是下平齐,还是齐,那相对应的调整管底标高,标高和顶标高。(此外,在做风管转化时,也要针对性的要使用对应的一种)。通风考虑的主要有风口、风管、风阀、风设备及一些附件。本次主要强调通风系统中风管和风阀操作注意事项:
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:一是风管的材质,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。这些参数更好看一下说明,如果没有的话参考05N4-3的相关规定。
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、通风管道中风阀的绘制及注意事项。关于风阀可以用转化,也可以直接绘制,方法可以参考转化设备。这里说一下风阀中比较特殊的内容。在管道里面,阀门是不扣减管道长度的,但在风管里面,风阀是要扣减掉风管的长度的,对于不同的风阀类型,有不同的扣减方法。
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.
