通風管道和風管的制作和安裝中常用的材料和其他材料應符合設計和實施標準，那么下面來講講通風管道效果是怎樣的吧。

Common materials and other materials used in the fabrication and installation of ventilation ducts and air ducts shall comply with the design and implementation standards, so let's talk about the effect of ventilation ducts.

1、有機廢氣從通風管道排出

1. Organic waste gas is discharged from the ventilation duct

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。

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.通風管道送冷空氣

2. cold air supplied by ventilation duct

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。

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、通風管道除灰

3. Air duct ash removal

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。

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對獨特管件的開發，主要包括曲折管件、經濟管等，以防止通風管在特定應用中移動和放松。

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 the development of unique pipe fittings, mainly including zigzag pipe fittings and economic pipes, so as to prevent the ventilation pipe from moving and relaxing in specific applications.

風管與離心風機連接時，進風口之間應加軟接頭。軟接頭的截面規格應與離心風機的進風口一致。一般軟管接頭可用白帆布、人造革等原材料制成。管子長度不小于200，松緊度要合適，軟塑料軟管可以緩沖離心風機的振動。風管與除塵設備、電加熱設備等連接前，應在設備安裝完成后，根據具體測繪項目的工程圖紙進行預制構件及安裝。

When the air duct is connected with the centrifugal fan, a soft joint shall be added between the air inlets. The Section specification of the flexible joint shall be consistent with the air inlet of the centrifugal fan. General hose joints can be made of white canvas, artificial leather and other raw materials. The length of the pipe shall not be less than 200, and the tightness shall be appropriate. The soft plastic hose can buffer the vibration of the centrifugal fan. Before connecting the air duct with dust removal equipment, electric heating equipment, etc., the prefabricated components and installation shall be carried out according to the engineering drawings of specific surveying and mapping projects after the equipment installation.

此外，濟南通風管道加工人員提醒您，傳統的通風空調工程風管采用水平連接方式，采用扁鋼制作成對法蘭，鉚接在風管的兩側和對面。墊片并用地腳螺栓將它們相互連接。由于材料、機器和工作的限制，管道不太可能加長以減少這種類型的連接。

In addition, Jinan ventilation duct processing personnel remind you that the traditional ventilation and air conditioning engineering air ducts are horizontally connected, and flat steel is used to make paired flanges, which are riveted on both sides and opposite sides of the air ducts. Shim and connect them with foundation bolts. Due to material, machine and work limitations, it is unlikely that the pipe will be lengthened to reduce this type of connection.

通風管道的考慮主要包括通風口、管道、風門、風設備和一些配件。這次鍍鋅圓法蘭主要強調的是通風管道管道和通風管道系統中的風門的操作注意事項：它是風管的識別。風管改造前，其中一項內容是明確的，那就是風管的標高。使用高度調整命令查看時，有時顯示的結果會有所不同。這是因為管道和管道的標高是管道的標高。只要管道的高度很高，就將管道視為管道。

Ventilation ducts mainly include vents, ducts, dampers, air equipment and some accessories. The galvanized round flange mainly emphasizes the precautions for the operation of the ventilation duct and the damper in the ventilation duct system: it is the identification of the air duct. Before the reconstruction of air duct, one of the contents is clear, that is, the elevation of air duct. When viewing with the height adjustment command, sometimes the results displayed will be different. This is because the pipe and the elevation of the pipe are the center elevation of the pipe. Pipes are considered pipes as long as they are high.

焊接風管本身采用焊接工藝。經嚴格檢驗，可按客戶要求組裝。多種實用程序（常用卡箍和法蘭兩種）可以充分保證設備的穩定運行。使用壽命長，占地面積小。鍍鋅板螺旋風管制造工藝特點和優勢安裝施工條件：焊接風管排風系統和空調系統通風管的安裝一般需要在建筑物屋頂完成，安裝場地障礙已清理干凈。

Welding process is adopted for welding air duct. After strict inspection, it can be assembled according to customer requirements. A variety of utility programs (commonly used clamp and flange) can fully ensure the stable operation of the equipment. Long service life and small floor area. Manufacturing process characteristics and advantages of galvanized sheet spiral air duct installation and construction conditions: the installation of the exhaust system of the welded air duct and the ventilation pipe of the air conditioning system generally needs to be completed on the roof of the building, and the obstacles in the installation site have been cleared.
