| 通风管道道的安装规范要求有哪些 What are the installation specifications for ventilation ducts 1、安装通风管道前，应将图纸与施I现场进行核对，检查能否按设计的标高和位置进行安装。 1. Before installing the ventilation duct, the drawings should be checked with the construction site to see if it can be installed according to the designed elevation and position. 2、使用红外线定位放线,确保通风管道的间距及直线度,并按通风管道的中心线，找出吊杆安装位置，进行支 吊架安装。 2. Use infrared positioning and setting out to ensure the spacing and straightness of the ventilation ducts, and locate the installation position of the suspension rod according to the centerline of the ventilation duct, and install the support and hanger. 3、通风管道系统的各部分尺寸和角度确认准确无误后，开始组对安装,通风管道的连接应平直、不扭曲，且连接法兰的螺母应在同一侧。 3. After confirming the accuracy of the dimensions and angles of each part of the ventilation duct system, start the assembly and installation. The connection of the ventilation duct should be straight and not twisted, and the nuts of the connecting flanges should be on the same side. 4、通风管道与通风管道法兰间的垫片采用厚3mm及以上的耐热橡胶板,垫片不应凸入管内,亦怀宜突出法兰，且垫片中不应含有石棉及其它有害成分，且应耐油耐潮耐酸碱腐蚀。 4. The gasket between the ventilation duct and the flange of the ventilation duct should be made of heat-resistant rubber plate with a thickness of 3mm or more. The gasket should not protrude into the pipe, and should also protrude from the flange. The gasket should not contain asbestos or other harmful components, and should be resistant to oil, moisture, acid, and alkali corrosion. 5、通风管道安装时，保持通风管道中心线的水平，安装-段通风管道后使用水平 尺测量水平;通风管道长度超过20m时，设置防架，晦个系统不少于- -副。 5. When installing the ventilation duct, maintain the level of the centerline of the ventilation duct, and measure the level with a level ruler after installing a section of the ventilation duct; When the length of the ventilation duct exceeds 20m, a protective frame shall be installed, and the number of concealed systems shall not be less than - pairs. 6、在通风管道穿过需要封闭的防火、防爆的墙体或楼板时，应设预埋管或防护套管，其钢板厚度为2mm。通风管道与防护套管之间，应用不燃且阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具对人体无危害的柔性材料封堵。 6. When the ventilation pipeline passes through fire-resistant and explosion-proof walls or floors that need to be sealed, embedded pipes or protective sleeves should be installed, with a steel plate thickness of 2mm. The ventilation duct and protective sleeve should be sealed with non combustible and non hazardous flexible materials. |
