如今，在施工安裝中，為了保護里面工作人員的健康，通風管道的使用也越來越多。要知道通風管道是否有效，您應該在處理它們時更多地了解正確的事情。讓我們來看看。
Nowadays, in the construction and installation, in order to protect the health of the staff inside, ventilation ducts are used more and more. To know whether the ventilation ducts are effective, you should know more about the right things when dealing with them. Let's have a look.
通風管道的作用：
Function of ventilation duct:
1、有機廢氣由通風管道排出。飯店、賓館的廚房會產生大量的廚房油煙，必須排盡。通風管道是專門的污水處理機械設備。
1. The organic waste gas is discharged from the ventilation duct. The kitchens of restaurants and hotels will produce a lot of kitchen oil smoke, which must be exhausted. Ventilation duct is a special mechanical equipment for sewage treatment.
2.通風管道供應冷空氣。通常使用空調管道，必須進行保溫隔熱。螺旋風道內可粘貼保溫材料，表面美觀大方。
2. the ventilation duct supplies cold air. Central air conditioning pipes are usually used and must be insulated. The spiral air duct can be pasted with thermal insulation materials, and the surface is beautiful and generous.
3、通風管道除塵。在一些加工廠和生產線上，粉塵量大，需要專門的除塵設備。螺旋風管可用于纏繞大量的總風管流量。
3. Dust removal of ventilation duct. In some processing plants and production lines, there is a large amount of dust, so special dust removal equipment is required. Spiral duct can be used to wind a large amount of total duct flow.
具體應用條件等領域正在加強。此外，還可以采用防松加固法。這種方法主要是加強獨特的管件，主要包括曲折的管件、翹曲的管件等，以防止通風管道在特定應用中移動和松動.
Specific application conditions and other fields are being strengthened. In addition, anti loose reinforcement method can also be used. This method is mainly to strengthen unique pipe fittings, mainly including zigzag pipe fittings, warped pipe fittings, etc., to prevent the ventilation pipe from moving and loosening in specific applications
處理通風管道時的正確事項；
Correct matters when handling ventilation ducts;
1、通風管道在加工過程中應盡量避免豎縫，但不得出現橫縫。此外，通風管道的咬縫和四個角的縫隙需要按照設計清潔度要求進行密封，然后用密封膠密封。另外，通風管片連接縫的密封面應設置在通風管壁的正壓側。
1. Vertical joints shall be avoided as far as possible during the processing of ventilation pipes, but transverse joints shall not occur. In addition, the undercut and four corner gaps of the ventilation duct shall be sealed according to the design cleanliness requirements, and then sealed with sealant. In addition, the sealing surface of the joint of the ventilation pipe segment shall be set at the positive pressure side of the ventilation pipe wall.
2、在加工過程中，不能在通風管道內設置鋼筋框架或鋼筋，因為這會對通風管道的質量產生一定的影響。
2. During the processing, the reinforcement frame or reinforcement shall not be set in the ventilation duct, because it will have a certain impact on the quality of the ventilation duct.
3、S型嵌件和C型直角嵌件的連接方式不能用于通風管道的加工。此外，對于一些特殊的通風管道，不能使用卡扣式咬合。
3. The connection mode of S-type insert and C-type right angle insert cannot be used for the processing of ventilation duct. In addition, for some special ventilation ducts, snap type bite cannot be used.
4、
濟南通風管道加工制造后，必須用清洗液清洗。只有達到清潔標準后，才能及時封存。
4. Jinan ventilation pipe must be cleaned with cleaning fluid after processing and manufacturing. Only after the cleaning standard is met can it be sealed in time.
5、如果是彩涂鋼板風管，內壁應保持光滑，風管加工過程中不得損傷涂層。如果有損壞，需要在表面涂上環氧樹脂能。另外，在風管加工過程中，必須采取防腐措施，不能使用盲鉚釘，而且在風管部件組裝時，這些部件必須鍍鋅。
5. 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. In case of damage, the surface shall be coated with epoxy resin. In addition, during the processing of air duct, anti-corrosion measures must be taken, blind rivets cannot be used, and these parts must be galvanized during the assembly of air duct parts.
