風(fēng)管截面C形、S形插條相關(guān)規(guī)則有哪些？
矩形風(fēng)管的截面積，其主要取決于什么?其C形、S形插條相關(guān)規(guī)則請(qǐng)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(fēng)管的截面積，其從角度來(lái)講，其是由主機(jī)風(fēng)量微風(fēng)壓大小這兩個(gè)來(lái)決議的。而在這一種風(fēng)管上，其C形、S形插條的相關(guān)規(guī)則請(qǐng)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(yīng)運(yùn)用特地的機(jī)械設(shè)備停止軋制加工，并且，其插口寬度應(yīng)與風(fēng)管相匹配。C形插條兩端的延長(zhǎng)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(fēng)管邊長(zhǎng)應(yīng)不大于630mm。假如，S形平插條單獨(dú)運(yùn)用的話，那么，在銜接處應(yīng)有相應(yīng)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(fēng)管插口，它們?cè)阢暯由蠎?yīng)做到平整和緊密。此外，程度插條長(zhǎng)度，應(yīng)與風(fēng)管寬度堅(jiān)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(zhì)的矩形風(fēng)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(fēng)管的資料和應(yīng)用
Data and application of rectangular duct
塑料矩形風(fēng)管，其是矩形風(fēng)管中的一種，其在運(yùn)用資料上，普通來(lái)講，是為硬聚氯乙烯塑料板，然后經(jīng)過(guò)加工來(lái)得到的一種風(fēng)管。不過(guò)，由于這一資料的熱穩(wěn)定性比擬差，所以，該風(fēng)管是有運(yùn)用溫度范圍的，是為-10℃—60℃。在其應(yīng)用上，主要是在腐蝕性氣體的保送上，由于它化學(xué)穩(wěn)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.
