　　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制作工藝

　　03 Production process

　　? ? ? 通風(fēng)管道的制作工藝對(duì)其使用性能和安全性至關(guān)重要。一般來(lái)說(shuō)，通風(fēng)管道的制作工藝包括以下幾個(gè)步驟：1. 劃線：根據(jù)風(fēng)管的不同尺寸、形狀和規(guī)格進(jìn)行劃線，確保下料的準(zhǔn)確性。2. 板材剪切：依據(jù)劃線形狀使用機(jī)械剪刀進(jìn)行剪切，并進(jìn)行下料復(fù)核。3. 倒角：板材下料后在軋口之前進(jìn)行倒角工作。4. 連接：金屬薄鋼板制作的風(fēng)管可以采用咬口連接、鉚釘連接、焊接等不同方法。連接時(shí)必須確保焊縫均勻、無(wú)裂紋及加渣現(xiàn)象，鉚釘連接時(shí)鉚釘中心要垂直于面板，使板材密合并排列整齊。5. 折方和卷圓：將咬口兩端拍成圓弧狀放在卷圓機(jī)上卷圓，按風(fēng)管直徑規(guī)格適當(dāng)調(diào)整上、下輥間距。6. 縫合：折方或卷圓后的鋼板用合口機(jī)或手工進(jìn)行縫合，確保單、雙口確定咬合，無(wú)臟裂或半咬口現(xiàn)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特殊應(yīng)用

　　04 Special Applications

　　在醫(yī)療領(lǐng)域，通風(fēng)管還具有特殊的應(yīng)用。醫(yī)用通風(fēng)管通常由柔軟的塑料或橡膠材料制成，一端連接到呼吸機(jī)或通氣設(shè)備，另一端連接到患者的氣道。這種通風(fēng)管的選擇應(yīng)根據(jù)患者的年齡、病情和治療需求進(jìn)行，以確保通氣效果和患者的舒適度。在使用時(shí)，需要嚴(yán)格遵守?zé)o菌操作規(guī)范，定期更換通風(fēng)管以減少感染風(fēng)險(xiǎn)。

　　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.

　　? ? ?綜上所述，通風(fēng)管是一種多功能的管道系統(tǒng)，在多個(gè)領(lǐng)域發(fā)揮著重要作用。其制作工藝復(fù)雜且要求嚴(yán)格，以確保其使用性能和安全性。同時(shí)，在特殊應(yīng)用場(chǎng)合如醫(yī)療領(lǐng)域，通風(fēng)管還具有特定的使用要求和操作規(guī)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.
