1、设置在染毒区的进，排风管，应采用了3mm厚的钢板焊接成型。其抗力和密闭防毒功能必须满足的防护需要，且风管应按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、穿过防护密闭墙的通风管应采用带3mm厚密闭套管，并应在土建施工时一次预埋到位。管路与设备法兰间采用橡胶密封垫圈等措施。

　　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、自动排气活门应与室内的通风短管在垂直和水平方向错开布置以利气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、口部气密测量管的预埋，防空地下室每个口部防毒通道，密闭通道的防护密闭门门框，墙上设置DN50热镀锌钢管的气密测量管。气密测量管在墙中设置密闭助采用3mm厚的钢板制作，并应与结构钢筋焊牢。管的两端伸出门框墙墙边50至100mm,管两端外的制作外螺纹。安装铜质带丝管帽密闭封堵。

　　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、防火阀和排烟防火阀动作，温度不同，防火阀为70℃，排烟防火阀为280℃，不能弄错。排烟风管安装时法兰回填料必须是不燃耐高温材料。如石棉板或石棉绳。

　　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、风机等设备安装时应正确选用减震吊钩或减震器，减少震动降低噪声。

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