1. No other pipelines are allowed to cross the air duct
2.安裝在易燃、易爆環(huán)境下的風管應有良好的接地，通過生活區(qū)或者生產區(qū)的風管安裝一定要嚴密，并且不能設備風管接口。
2. The air duct installed in the flammable and explosive environment shall be well grounded. The air duct passing through the living area or production area must be tightly installed, and the air duct interface shall not be equipped.
3.室外立式風管的固定不得與避雷針或房屋避雷設施連接到一起。
3. The fixing of outdoor vertical air duct shall not be connected with lightning rod or house lightning protection facilities.
4.風管安裝符合以下技術規(guī)定：
4. The installation of air duct shall comply with the following technical regulations:
①風管與通風設備，配件連接的配置，不得縮小其連接部位的連接管。
① The configuration of the connection between the air duct and the ventilation equipment and accessories shall not reduce the connection pipe of its connection part.
②吊架不能設置在風口、風閥、檢查門及自控機構處，不得固定在法蘭上，避免風管變形影響風管的作用。
② The hanger shall not be set at the air outlet, air valve, inspection door and automatic control mechanism, and shall not be fixed on the flange to avoid the effect of air duct deformation on the air duct.
③吊架安裝符合相應的安裝規(guī)定，懸吊的風管與部件應設防止擺動的固定點，如固定支架、支撐等，固定點的設置位置和數量應根據系統(tǒng)情況而定。
③ The installation of hangers shall comply with the corresponding installation regulations. The suspended air ducts and components shall be provided with fixed points to prevent swing, such as fixed supports, supports, etc. The location and number of fixed points shall be determined according to the system conditions.
④法蘭墊料和厚度根據輸送空氣溫度的不同，選擇的材質也不同。
④ The flange gasket and thickness are different according to the temperature of the conveying air.
⑤風管及部件穿墻、屋面時，應設置防雨罩，穿出屋面的風管超過1.5m時應拉索，拉索應鍍鋅或用鋼絲繩，拉索禁止固定在風管法蘭上，嚴禁拉在避雷針或避雷網上。
⑤ When the air duct and its components pass through the wall and roof, a rain cover shall be provided. When the air duct passing through the roof exceeds 1.5m, a stay cable shall be provided. The stay cable shall be galvanized or steel wire rope. It is prohibited to fix the stay cable on the air duct flange, and it is prohibited to pull it on the lightning rod or lightning protection network.
⑥柔性短管的安裝應松緊適度，不得扭曲，可伸縮性的金屬或非金屬軟風管的長度不宜超過2m，并不得有死彎及塌凹。
⑥ The flexible short pipe shall be installed with appropriate tightness and shall not be twisted. The length of flexible metal or non-metallic flexible air duct shall not exceed 2m, and there shall be no dead bend or concavity.
⑦保溫風管的支、吊架宜設在保溫層的外部，并不得破壞保溫層。
⑦ The supports and hangers of thermal insulation air ducts should be set outside the thermal insulation layer and should not damage the thermal insulation layer.
