    洁净间风口的规格、尺寸、形式应符合设计要求,表面平整、无变形,自带调节部分应灵活、无卡涩和松动,表面喷涂的风口应颜色均匀、无色差、表面无划痕;风管无法兰连接时,采用法兰插条和弹簧夹的规格、厚度、强度应能满足设计和使用要求;风阀、柔性短管、风帽和消声器采用法兰连接时,其法兰规格应与风管法兰规格相匹配。
    The specification, size and form of the air outlet in the clean room shall meet the design requirements, and the surface shall be flat and free of deformation. The self-contained regulating part shall be flexible, free from jamming and loosening. The air outlet sprayed on the surface shall be of uniform color, without color difference and surface scratch. When the air duct is not connected with flange, the specification, thickness and strength of flange insert and spring clip shall meet the design and application requirements; the air valve and flexibility shall meet the design and application requirements When flange connection is adopted for short pipe, hood and muffler, the flange specification shall match with that of air duct flange.
    风管支吊架制作前,先要对型钢进行矫正,矫正的方法通常有冷矫和热矫两种,小型钢材一般采用冷矫正,较大的型钢须加热到900℃左右后进行矫正,矫正顺序为先矫正扭曲,后矫正弯曲;支架、吊架的螺栓孔和切断应采用机械加工,不允许用电气焊切割,抱箍的圆弧应与风管外径一致,支吊架的焊接应外观整洁漂亮,要保证焊牢、焊透,不得有欠焊、漏焊、裂纹、咬肉等缺陷;吊杆应平直、螺纹应完整、光洁,吊杆应根据风管安装标高适当截取,吊杆下端露出螺母长度不宜过长。
    Before the fabrication of air duct supports and hangers, the section steel should be corrected first. The correction methods usually include cold straightening and hot straightening. The small steel should be generally cold straightened, and the larger section steel should be heated to about 900 ℃ for correction. The correction sequence is to correct the distortion first, and then to correct the bending; the bolt holes and cut-off of supports and hangers should be machined, and it is not allowed to use electric welding to cut and hold hoop The circular arc shall be consistent with the outer diameter of the air duct, and the welding of the supports and hangers shall be neat and beautiful in appearance, and the welding shall be firm and thorough, and there shall be no defects such as lack of welding, missing welding, cracks and undercutting; the suspender shall be straight, and the thread shall be complete and smooth; the hanger rod shall be properly cut according to the installation elevation of the air duct, and the length of the nut exposed at the lower end of the suspender shall not be too long.

    风管接口的连接应牢固、严密,风管法兰的垫片材质应符合系统功能的要求,厚度不应小于3mm垫片不得凸入管内,也不能突出法兰外;柔性短管的安装应松紧适度,不得扭曲;风管与砖、混凝土风道的插接应顺气流方向,风管插入端与风道表面应齐平,并应进行密封处理。
    The connection of air duct interface shall be firm and tight, the gasket material of air duct flange shall meet the requirements of system function, the thickness shall not be less than 3mm, the gasket shall not protrude into the pipe or protrude from the flange; the installation of flexible short pipe shall be moderately tight without distortion; the connection between air duct and brick and concrete air duct shall be in the direction of air flow, and the insertion end of air duct shall be flush with the surface of air duct and shall be tight Sealing.
    风管的连接处应完整无缺损,风管连接两平面应平直,无明显扭曲;承插式风管的四周缝隙应一致,无明显的弯曲或褶皱,内涂的密封胶应完整,外粘的密封胶带应粘贴牢固、完整;薄钢板法兰形式的风管拦截,弹性插条、弹簧夹或紧固螺栓的间隔不应大于且分布均匀,无松动现象;明装风管水平安装,水平度偏差为3‰,总偏差不应大于20mm,明装风管垂直安装,垂直偏差为2‰,总片产不应大于20mm。
    The joint of air duct shall be complete without defect, and the two planes of air duct connection shall be straight and straight without obvious distortion; the surrounding gap of socket type air duct shall be consistent without obvious bending or fold; the sealant applied inside shall be complete; the sealing tape attached externally shall be firmly and completely pasted; the air duct intercepted in the form of thin steel sheet flange, and the spacing of elastic insert, spring clip or fastening bolt shall not be greater than and distributed Even, no looseness; the horizontal deviation of open air duct is 3 ‰, and the total deviation should not be greater than 20 mm. For the vertical installation of open air duct, the vertical deviation is 2 ‰, and the total production should not be greater than 20 mm.
    暗装风管位置应正确,无明显偏差;螺旋风管的安装宜采用无法兰连接,安装在支架上的圆形风管应设托座;送风支管与总管,采用垂直插接时,其接口处应设置导风调节装置。中净环球净化可提供洁净间、洁净室</a></strong>的咨询、规划、设计、施工、安装、改造等配套服务。
    The position of concealed air duct should be correct without obvious deviation; the installation of spiral air duct should be connected without flange, and the round air duct installed on the support should be provided with bracket; when the air supply branch pipe and main pipe are connected vertically, the air guide regulating device should be set at the interface.
