　　02主要用途

　　02 Main purpose

　　通风管在多个领域发挥着重要作用，主要包括：1. 提供新鲜空气：通过外部污染物过滤器将新鲜空气引入室内，改善室内空气质量。2. 排除室内污染物：如厨房的油烟、浴室的潮湿气氛和化学物质等，确保室内空气清新。3. 控制室内温度和湿度：在夏季，通过排放热气体和湿气的方式降低室内温度；在冬季，通过回收和加热外部冷空气的方式提供温暖的室内空气。4. 防止火灾蔓延：在建筑物中设置阻火隔断，阻止火灾蔓延到其他楼层和房间。5. 增强建筑结构稳定性：通过合理设计和布置通风管道，可以在某些情况下起到支撑、加固建筑结构的作用。6. 提高工作环境质量：在工业场所中，通风管道用于排出有害气体、粉尘和烟雾等，改善工作环境质量。

　　Ventilation ducts play an important role in multiple fields, including: 1 Provide fresh air: Introduce fresh air indoors through external pollutant filters to improve indoor air quality. 2. Eliminate indoor pollutants such as kitchen fumes, humid atmosphere in the bathroom, and chemicals to ensure fresh indoor air. 3. Control indoor temperature and humidity: In summer, reduce indoor temperature by emitting hot gases and moisture; In winter, warm indoor air is provided by recycling and heating external cold air. 4. Preventing the spread of fire: Install fire-resistant partitions in buildings to prevent the spread of fire to other floors and rooms. 5. Enhance the stability of building structures: By designing and arranging ventilation ducts reasonably, they can play a role in supporting and reinforcing building structures in certain situations. 6. Improve the quality of the working environment: In industrial settings, ventilation ducts are used to exhaust harmful gases, dust, and smoke, improving the quality of the working environment.

　　03制作工艺

　　03 Production process

　　? ? ? 通风管道的制作工艺对其使用性能和性关重要。一般来说，通风管道的制作工艺包括以下几个步骤：1. 划线：根据风管的不同尺寸、形状和规格进行划线，确保下料的准确性。2. 板材剪切：依据划线形状使用机械剪刀进行剪切，并进行下料复核。3. 倒角：板材下料后在轧口之前进行倒角工作。4. 连接：金属薄钢板制作的风管可以采用咬口连接、铆钉连接、焊接等不同方法。连接时必须确保焊缝均匀、无裂纹及加渣现象，铆钉连接时铆钉中心要垂直于面板，使板材密合并排列整齐。5. 折方和卷圆：将咬口两端拍成圆弧状放在卷圆机上卷圆，按风管直径规格适当调整上、下辊间距。6. 缝合：折方或卷圆后的钢板用合口机或手工进行缝合，确保单、双口确定咬合，无脏裂或半咬口现象。

　　? ? ?  The manufacturing process of ventilation ducts is crucial for their performance and safety. Generally speaking, the manufacturing process of ventilation ducts includes the following steps: 1 Marking: Mark according to the different sizes, shapes, and specifications of the air duct to ensure the accuracy of cutting. 2. Plate cutting: Use mechanical scissors to cut according to the marked shape and conduct cutting review. 3. Chamfering: Chamfering work is carried out before the rolling of the plate after cutting. 4. Connection: Air ducts made of metal thin steel plates can be connected using different methods such as bite joint connection, rivet connection, welding, etc. When connecting, it is necessary to ensure that the weld seam is uniform, free of cracks and slag. When connecting with rivets, the center of the rivet should be perpendicular to the panel to ensure that the plate is tightly packed and arranged neatly. 5. Folding and rounding: Beat the two ends of the bite into a circular arc shape and place it on the rounding machine to roll it. Adjust the distance between the upper and lower rollers appropriately according to the diameter specifications of the air duct. 6. Stitching: The folded or rolled steel plate is sewn with a joint machine or manually to ensure that the single and double joints are firmly engaged, without any dirty cracks or half biting.

　　04特殊应用

　　04 Special Applications

　　在医疗领域，通风管还具有特殊的应用。医用通风管通常由柔软的塑料或橡胶材料制成，一端连接到呼吸机或通气设备，另一端连接到患者的气道。这种通风管的选择应根据患者的年龄、病情和需求进行，以确保通气效果和患者的舒适度。在使用时，需要严格遵守无菌操作规范，定期更换通风管以减少感染风险。

　　In the medical field, ventilation ducts also have special applications. Medical ventilation ducts are usually made of soft plastic or rubber materials, with one end connected to a ventilator or ventilation device and the other end connected to the patient's airway. The selection of this ventilation duct should be based on the patient's age, condition, and treatment needs to ensure ventilation effectiveness and patient comfort. When using, it is necessary to strictly follow aseptic operating procedures and regularly replace ventilation pipes to reduce the risk of infection.

　　? ? ?综上所述，通风管是一种多功能的管道系统，在多个领域发挥着重要作用。其制作工艺复杂且要求严格，以确保其使用性能和性。同时，在特殊应用场合如医疗领域，通风管还具有特定的使用要求和操作规范。

　　? ? ? In summary, ventilation ducts are multifunctional piping systems that play important roles in multiple fields. Its production process is complex and requires strict standards to ensure its performance and safety. At the same time, in special applications such as the medical field, ventilation ducts also have specific usage requirements and operating standards.
