通风系统中风管和风阀的注意事项!

  在安装计算中,有一个专业的暖通空调,其中通风系统是一个非常重要的环节。用通风系统说明操作方法及注意事项。
  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,通风系统的安装计算有两种方法,一种是绘图法,另一种是改造法。这次针对的是转换模式的应用。
  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.
  通风专业主要考虑风口、风管、阀门、风设备等一些配件。
  Ventilation specialty mainly considers some accessories such as tuyeres, ducts, valves, air equipment, etc.
  本次主要强调通风系统风管、风门运行中应注意的事项:
  This paper mainly emphasizes the matters needing attention in the operation of air duct and air valve of ventilation system.
  首先,风道的识别
  Firstly, the identification of airway
  在管道改造之前,有一件事必须弄清楚,那就是管道的标高。当使用高度调整命令查看时,结果有时会有所不同。这是因为管道的标高而管道是管道的中心标高。如果你在做导管,你会做得有点不同。比如管道的底部,或者中心,或者顶部。因此,在使用风管之前,要先看图纸上的风管是顶部冲洗,底部冲洗还是中心冲洗,并相应地调整底部标高、中心标高和顶部标高。(此外,在做风管改造时,也应有针对性地使用相应的风管)。
  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.

  现在我们要做好风管改造工作。在这一步中,我们需要输入以下几个方面:首先,风管的材质;二是风管壁厚;三是风管接口类型;四是风管保温厚度。更好的方法是更好地查看这些参数。如果没有,请参考05n4-3的相关规定。
  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.
  气阀图纸及注意事项
  Drawing of valve and matters needing attention
  关于风阀可以转换,也可以直接绘制,该方法可参考转换设备。这里说的风阀内容比较特殊。在管道主要,阀门不扣除管道的长度,但在风管中,风管阀门是扣除风管的长度,对于不同类型的风管阀门,有不同的扣除方法。如下图所示,无论风管的宽度是多少,气阀的扣紧量都是固定的;有些风管的宽度上有什么值,风门的长度扣固定加上风管的高度(或半径);在另一种情况下,管道的宽度与阀门的长度相对应。我们可以根据具体要求选择不同类型的气阀。
  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.
