风管截面C形、S形插条相关规则有哪些?
矩形风管的截面积,其主要取决于什么?其C形、S形插条相关规则请求,有哪些?
 
  What is the cross-sectional area of rectangular duct mainly depending on? What are the requirements of relevant rules for C-shaped and S-shaped slots?
 
  矩形风管的截面积,其从专业角度来讲,其是由主机风量微风压大小这两个来决议的。而在这一种风管上,其C形、S形插条的相关规则请求,是为:
 
  The cross-sectional area of rectangular duct is determined by the main engine's air volume and breeze pressure from a professional point of view。 In this kind of duct, the relevant rules of C-shaped and S-shaped inserts are required for:
 
  (1)C形和S形插条,应运用特地的机械设备停止轧制加工,并且,其插口宽度应与风管相匹配。C形插条两端的延长量,不能小于20mm。
 
  (1) For C-shaped and S-shaped inserts, special mechanical equipment should be used to stop rolling, and the width of the insert should be matched with the air duct. The elongation at both ends of C-shaped cutter should not be less than 20 mm.
 
  (2)采用C形和S形平插条的话,风管边长应不大于630mm。假如,S形平插条单独运用的话,那么,在衔接处应有相应的固定措施。此外,C形直角插条,其可用于支管和主干管的衔接。
 
  (2) If C-shaped and S-shaped horizontal inserts are used, the length of the side of the air duct shall not exceed 630 mm。 If the S-shaped spline is used alone, then corresponding fixing measures should be taken at the joints。 In addition, the C-shaped right-angle socket can be used for the connection of branch pipe and main pipe。

  (3)插条与风管插口,它们在衔接上应做到平整和紧密。此外,程度插条长度,应与风管宽度坚持分歧。在插接完成后,能够是有折角。
 
  (3) The connection between the outlet and the air duct outlet should be smooth and close。 In addition, the length of the degree insert should be different from the width of the duct。 After the plug-in is completed, it can be folded。
 
  此外,我们需求晓得的是,假如是铝板材质的矩形风管,那么,是不能用C形、S形平插条停止衔接。
 
  In addition, what we need to know is that if the rectangular air duct is made of aluminium sheet, then the connection can not be stopped with C-shaped and S-shaped splines.
 
  矩形风管的资料和应用
 
  Data and application of rectangular duct
 
  塑料矩形风管,其是矩形风管中的一种,其在运用资料上,普通来讲,是为硬聚氯乙烯塑料板,然后经过加工来得到的一种风管。不过,由于这一资料的热稳定性比拟差,所以,该风管是有运用温度范围的,是为-10℃—60℃。在其应用上,主要是在腐蚀性气体的保送上,由于它化学稳定性好。
 
  Plastic rectangular air duct is one of the rectangular air ducts。 Generally speaking, it is a kind of air duct made of rigid polyvinyl chloride plastic sheet and processed。 However, due to the poor thermal stability of this data, the air duct has a range of applied temperature, which is - 10 C - 60 C。 In its application, mainly in the delivery of corrosive gases, because of its good chemical stability。
