對于通風(fēng)管道，我們可以在一些大型公共場所看到它們，例如寫字樓和。通風(fēng)管道是一種空心管道，多為圓形或方形。下面講講通風(fēng)管道加工安裝的六大注意事項(xiàng)具體內(nèi)容。

For ventilation ducts, we can see them in some large public places, such as office buildings and shopping malls. Ventilation duct is a kind of hollow duct, which is mostly round or square. Next, we will talk about the specific contents of the six precautions for the processing and installation of ventilation pipes.

1、通風(fēng)管道在加工過程中，應(yīng)盡量避免縱向接縫，但不應(yīng)出現(xiàn)橫向接縫。此外，通風(fēng)管道的底切和拐角需要根據(jù)設(shè)計(jì)清潔度要求用密封膠密封。另外，排氣管接頭的密封面應(yīng)設(shè)置在排氣管壁的正壓側(cè)。

1. During the processing of ventilation pipes, longitudinal joints should be avoided as far as possible, but transverse joints should not appear. In addition, the undercut and corner of the ventilation duct need to be sealed with sealant according to the design cleanliness requirements. In addition, the sealing surface of the exhaust pipe joint should be set on the positive pressure side of the exhaust pipe wall.

2、在風(fēng)管加工過程中，不能在風(fēng)管上設(shè)置加強(qiáng)框或加強(qiáng)筋，因?yàn)檫@樣會對風(fēng)管的質(zhì)量產(chǎn)生一定的影響。

2. In the process of air duct processing, reinforcing frames or ribs cannot be set on the air duct, because this will have a certain impact on the quality of the air duct.

3、風(fēng)管加工不能采用“S”型切割和“C”型直角切割的連接方式。此外，一些特殊的通風(fēng)管道不能堵塞。

3. The connection mode of "s" type cutting and "C" type right angle cutting cannot be adopted for air duct processing. In addition, some special ventilation ducts should not be blocked.

4、通風(fēng)管完成后，用清洗液清洗。只有達(dá)到清潔標(biāo)準(zhǔn)后，才能及時(shí)封存。

4. After the ventilation pipe is completed, clean it with cleaning fluid. Only after reaching the cleaning standard can it be sealed in time.

5、玻纖復(fù)合板的風(fēng)嘴為截面時(shí)，在裝配法蘭接頭前，應(yīng)將管端截面用膠帶或膠水密封，防止玻璃纖維外露和散落。

5. When the air nozzle of the glass fiber composite board is a cross-section, the cross-section of the pipe end should be sealed with tape or glue before assembling the flange joint to prevent the glass fiber from being exposed and scattered.

6、如果是彩涂鋼板風(fēng)管，內(nèi)壁應(yīng)保持光滑，風(fēng)管加工過程中不得損傷涂層。如果零件損壞，表面應(yīng)涂上環(huán)氧樹脂。此外，在山東通風(fēng)管道加工過程中應(yīng)采取防腐措施。不應(yīng)使用空心鉚釘。裝配通風(fēng)管道部件時(shí)，這些部件應(yīng)鍍鋅。

6. If the air duct is made of color coated steel plate, the inner wall shall be kept smooth, and the coating shall not be damaged during the processing of the air duct. If the parts are damaged, the surface should be coated with epoxy resin. In addition, anti-corrosion measures should be taken during the processing of ventilation pipes in Shandong. Blind rivets should not be used. When assembling ventilation duct components, these components shall be galvanized.

此外風(fēng)管加工過程中，風(fēng)管上不得設(shè)置加強(qiáng)框或加強(qiáng)筋，不得使用卡扣。制作完成后用清洗液清洗密封，注意零件使用！

In addition, during the processing of air duct, no reinforcing frame or reinforcing rib shall be set on the air duct, and no buckle shall be used. Clean the seal with cleaning fluid after fabrication, and pay attention to the use of parts!

總之，通風(fēng)管道的生產(chǎn)加工對后期的使用和操作人員的系數(shù)有很大的影響。因此，操作人員有必要了解加工通風(fēng)管道的注意事項(xiàng)。更多事項(xiàng)的了解就來我們網(wǎng)站http://www.pvcbox.cn吧！

In short, the production and processing of ventilation ducts have a great impact on the later use and the safety factor of operators. Therefore, it is necessary for operators to understand the precautions for processing ventilation ducts. Come to our website for more information http://www.pvcbox.cn Come on!
