　　1、設置在染毒區的進，排風管，應采用了3mm厚的鋼板焊接成型。其抗力和密閉防毒功能必須滿足的防護需要，且風管應按0.5%的坡度向室外。

　　1. The intake and exhaust ducts located in the contaminated area should be welded with 3mm thick steel plates. Its resistance and airtight anti toxic function must meet the protection requirements, and the air duct should face outdoors at a slope of 0.5%.

　　2、穿過防護密閉墻的通風管應采用帶3mm厚密閉套管，并應在土建施工時一次預埋到位。管路與設備法蘭間采用橡膠密封墊圈等措施。

　　2. Ventilation pipes passing through protective sealed walls should be equipped with 3mm thick sealed sleeves and should be pre embedded in place during civil construction. Rubber sealing gaskets and other measures are used between pipelines and equipment flanges.

　　3、自動排氣活門應與室內的通風短管在垂直和水平方向錯開布置以利氣流的排出不留有死角。

　　3. The automatic exhaust valve should be staggered with the indoor ventilation short pipe in both vertical and horizontal directions to facilitate the exhaust of airflow without leaving any blind spots.

　　4、口部氣密測量管的預埋，防空地下室每個口部防毒通道，密閉通道的防護密閉門門框，墻上設置DN50熱鍍鋅鋼管的氣密測量管。氣密測量管在墻中設置密閉助采用3mm厚的鋼板制作，并應與結構鋼筋焊牢。管的兩端伸出門框墻墻邊50至100mm,管兩端外的制作外螺紋。安裝銅質帶絲管帽密閉封堵。

　　4. Pre embedding of airtight measuring tubes at the mouth, installation of protective airtight door frames for each gas defense passage in the air defense basement, and installation of airtight measuring tubes made of DN50 hot-dip galvanized steel pipes on the wall. The airtight measuring tube is installed in the wall and made of 3mm thick steel plate, which should be welded firmly to the structural steel bars. The two ends of the pipe protrude 50 to 100mm from the door frame wall, and external threads are made on both ends of the pipe. Install copper threaded pipe caps for sealed sealing.

　　5、防火閥和排煙防火閥動作，溫度不同，防火閥為70℃，排煙防火閥為280℃，不能弄錯。排煙風管安裝時法蘭回填料必須是不燃耐高溫材料。如石棉板或石棉繩。

　　5. Fire dampers and smoke exhaust fire dampers operate at different temperatures. The fire damper operates at 70 ℃, while the smoke exhaust fire damper operates at 280 ℃. It cannot be mistaken. During the installation of smoke exhaust ducts, the flange backfill material must be non combustible and heat-resistant. Such as asbestos board or asbestos rope.

　　6、風機等設備安裝時應正確選用減震吊鉤或減震器，減少震動降低噪聲。

　　6. When installing equipment such as fans, shock-absorbing hooks or dampers should be selected correctly to reduce vibration and noise.
