風管截面C形、S形插條相關規則有哪些？

矩形風管的截面積，其主要取決于什么?其C形、S形插條相關規則請求，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?

　　矩形風管的截面積，其從角度來講，其是由主機風量微風壓大小這兩個來決議的。而在這一種風管上，其C形、S形插條的相關規則請求，是為：

　　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形插條，應運用特地的機械設備停止軋制加工，并且，其插口寬度應與風管相匹配。C形插條兩端的延長量，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形平插條的話，風管邊長應不大于630mm。假如，S形平插條單獨運用的話，那么，在銜接處應有相應的固定措施。此外，C形直角插條，其可用于支管和主干管的銜接。

　　(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)插條與風管插口，它們在銜接上應做到平整和緊密。此外，程度插條長度，應與風管寬度堅持分歧。在插接完成后，能夠是有折角。

　　(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，我們需求曉得的是，假如是鋁板材質的矩形風管，那么，是不能用C形、S形平插條停止銜接。

　　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.

　　矩形風管的資料和應用

　　Data and application of rectangular duct

　　塑料矩形風管，其是矩形風管中的一種，其在運用資料上，普通來講，是為硬聚氯乙烯塑料板，然后經過加工來得到的一種風管。不過，由于這一資料的熱穩定性比擬差，所以，該風管是有運用溫度范圍的，是為-10℃—60℃。在其應用上，主要是在腐蝕性氣體的保送上，由于它化學穩定性好。

　　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.
