通风管道和附件的制造以及在工程口的一个关闭阀门中安装管道和配件应通过焊接厚度为2至3毫米的钢板制成。焊缝应完整,均匀,紧密。通风管道应焊接。通风管和截止阀应与密封槽连接,接触应平稳;法兰垫圈应为全圆非接口橡胶密封圈。工程渗压计的末端应在防护关闭门的末端设有向下弯头;另一端应位于通风机房或控制室内,并应安装球阀。通过防病毒通道的压力测量管,接口应焊接。
The manufacture of ventilation pipes and accessories and the installation of pipes and accessories in a shut-off valve at the engineering port shall be made of welded steel plates with a thickness of 2 to 3 mm. Welds shall be complete, uniform and tight. Ventilation ducts shall be welded. The vent pipe and stop valve shall be connected with the sealing groove, and the contact shall be stable; Flange gasket shall be full circle non interface rubber sealing ring. The end of the engineering osmometer shall be provided with a downward elbow at the end of the protective closing door; The other end shall be located in the ventilator room or control room, and ball valve shall be installed. The interface of the pressure measuring pipe passing through the anti-virus channel shall be welded.
压力排水管应由供水铸铁管,镀锌管,镀锌钢管或UPVC塑料管制成。界面应由亚麻籽或石棉水泥制成,不应使用水泥砂浆。连接到管螺纹的填料应由甘油和红丹粉末混合制成。对于连接到管道法兰的垫圈,应在两侧使用石墨涂层石棉纸板,不得使用普通橡胶垫圈。
The pressure drainage pipe shall be made of cast iron pipe, galvanized pipe, galvanized steel pipe or UPVC Plastic pipe for water supply. The interface shall be made of flaxseed or asbestos cement, and cement mortar shall not be used. The packing connected to the pipe thread shall be made of a mixture of glycerol and red lead powder. For gaskets connected to pipe flanges, graphite coated asbestos paperboard shall be used on both sides, and ordinary rubber gaskets shall not be used.
通过管道的中线找到臂杆的位置。单臂位于管道的中线上。双臂可以根据托盘的螺孔间距或管道的中线对称安装。吊杆可以根据吊架的形式焊接到吊架上,也可以悬挂在吊架上。焊接后应涂防锈漆。当济南通风管道较长并需要安装一排支架时,可以先固定两端,然后使用两端的支架作为参考,通过电缆方法查找中间支架的高程。
Find the position of the arm through the center line of the pipe. The single arm is located on the center line of the pipe. The two arms can be installed symmetrically according to the screw hole spacing of the tray or the center line of the pipeline. The suspender can be welded to the hanger or hung on the hanger according to the form of the hanger. Anti rust paint shall be applied after welding. When the ventilation duct in Jinan is long and a row of supports need to be installed, fix both ends first, and then use the supports at both ends as a reference to find the elevation of the middle support through the cable method.
