通風管道主要應用在工業及建筑工程中，應用領域主要涉及:電子工業無塵廠房凈化系統，醫藥食品無菌車間凈化系統，酒店賓館、醫院、工廠及寫字樓的空調系統，工業污染控制用除塵、排煙、吸油等排風管、工業環境或崗位舒適用送風管、煤礦抽放瓦斯用抽放瓦斯系統、煤礦礦井環境控制用送回風系統。

The ventilation pipe is mainly used in industrial and construction projects, mainly related to application: purification system of electronic industry clean workshop, purifying system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, with the addition of dust, smoke and fume exhaust pipe, etc. industrial environment comfortable by feeding or post the wind pipe, coal mine gas drainage in coal mine gas drainage system, environmental control system of industrial pollution control air supply.

風管及部件的安裝

Installation of wind pipe and parts

風管及配件可拆卸的接口及調節閥門不得裝設在墻內或樓板內。風管及配件安裝前應內外雜物及污物并保持清潔。

The detachable interface and regulating valve of the wind pipe and accessories shall not be installed in the wall or in the floor. The internal and external impurities and dirt should be cleaned and kept clean before the installation of the wind pipe and accessories.

靠墻或靠柱安裝的水平、垂直風管宜采用懸臂支架或斜撐支架。不靠墻、柱安裝的水平風管宜用托底吊架，垂直風管應采用抱箍支架，風管b＞800mm應加雙螺帽。并在轉角處、頂端、末端設置防晃支架，支架不得設置在風口、閥門、檢查孔及自控機構處。吊架不宜直接固定在法蘭片上。

A horizontal and vertical wind pipe installed on a wall or a column should be supported by a cantilever bracket or a bracing support. Do not rely on the wall and column level wind pipe installed to use underpinning hanger, vertical wind pipe should be used in hoop bracket, duct b > 800mm should add double nut. At the corner, the top and the end, the anti - sway bracket is set up. The bracket shall not be set at the air vent, valve, check hole and automatic control mechanism. The hanger should not be fixed directly on the flange.

矩形風管抱箍支架應緊貼風管。如保溫風管，應留有保溫厚度浸瀝青的木塊風管吊架應平直、螺紋應光潔、吊桿拼接可采用焊接。長度不應少于吊桿直徑的六倍，并應在兩側焊接。

The brackets of the hoop of the rectangular wind pipe should be tightly attached to the wind pipe. If the heat insulation pipe, the wood block hanger of the wood block should be kept straight, the thread should be smooth and the splice of the hanger can be welded. The length should not be less than six times the diameter of the hanger, and should be welded on both sides.

通風管道一般有:凈化系統送回風管、空調通風管、工業送排風通風管、系統吸排風管、礦用抽放瓦斯管、礦用涂膠布風筒等。

Ventilation pipes usually include: purification system, return air pipe, central air conditioning ventilation pipe, industrial ventilation and ventilation pipe, environmental protection system suction and exhaust pipe, mine drainage gas pipe, mine coating cloth air duct and so on.

在通風系統中的風管是相互連接的一個整體，必然得遵循各支路阻力平衡規律，當風管系統的結構形式、管道尺寸一經確定，在一定的風機作用下，各段的風量是按阻力平衡規律自動分配的。在設計計算時未經阻力平衡計算，會導致系統實際風量分配與設計不符。

In the ventilation system of wind pipe is a whole connected, must follow the branch resistance balance law, when the structure, size of pipe duct system is confirmed, the fan under certain sections of the air volume according to the automatic distribution of resistance balance law. Without the calculation of resistance balance in the design and calculation, the actual air volume distribution and design of the system will not conform to the design.
