如今，在施工安装中，为了保护里面工作人员的健康，通风管道的使用也越来越多。要知道通风管道是否有效，您应该在处理它们时更多地了解正确的事情。让我们来看看。
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.
通风管道的作用：
Function of ventilation duct:
1、有机废气由通风管道排出。饭店、宾馆的厨房会产生大量的厨房油烟，必须排尽。通风管道是专门的污水处理机械设备。
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.通风管道供应冷空气。通常使用空调管道，必须进行保温隔热。螺旋风道内可粘贴保温材料，表面美观大方。
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、通风管道除尘。在一些加工厂和生产线上，粉尘量大，需要专门的除尘设备。螺旋风管可用于缠绕大量的总风管流量。
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.
具体应用条件等领域正在加强。此外，还可以采用防松加固法。这种方法主要是加强独特的管件，主要包括曲折的管件、翘曲的管件等，以防止通风管道在特定应用中移动和松动.
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
处理通风管道时的正确事项；
Correct matters when handling ventilation ducts;
1、通风管道在加工过程中应尽量避免竖缝，但不得出现横缝。此外，通风管道的咬缝和四个角的缝隙需要按照设计清洁度要求进行密封，然后用密封胶密封。另外，通风管片连接缝的密封面应设置在通风管壁的正压侧。
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、在加工过程中，不能在通风管道内设置钢筋框架或钢筋，因为这会对通风管道的质量产生一定的影响。
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型直角嵌件的连接方式不能用于通风管道的加工。此外，对于一些特殊的通风管道，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、
济南通风管道加工制造后，必须用清洗液清洗。只有达到清洁标准后，才能及时封存。
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、如果是彩涂钢板风管，内壁应保持光滑，风管加工过程中不得损伤涂层。如果有损坏，需要在表面涂上环氧树脂能。另外，在风管加工过程中，必须采取防腐措施，不能使用盲铆钉，而且在风管部件组装时，这些部件必须镀锌。
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.
