The invention relates to the technical field of bullet train air duct equipment, in particular to an air duct inner and outer flange bonding process for a high-speed railway. According to the process,bottom channel steel is included, bent beams are arranged on the outer walls of two sides of the bottom channel steel through bolts, top channel steel is arranged on the outer walls of the tops of the two bent beams through bolts, a middle end top plate is arranged on the outer wall of the top of the bottom channel steel through bolts, the outer wall of the top of the middle end top plate is fixedly connected with the top channel steel through bolts, one side of the outer wall of the back surface of the middle end top plate is provided with an inner flange through a bolt, one side of the outer wall of the front surface of the middle end top plate is provided with an outer flange through a bolt, and a cavity is reserved between the outer wall of one end of the inner flange and the outer wall of one end of the outer flange. The process has the beneficial effects that the process is simple, a sealant is added on the basis of an existing process, the sealing effect of an air duct is improved, the service life of the air duct is prolonged, when the sealant is used, the sealant has high tensile strength, good elasticity, wear resistance and the like, and the service life of a joint of the inner flange and the outer flange can be prolonged.
本发明涉及动车风道设备技术领域,具体是一种高铁的风道内外法兰粘结工艺,包括底部槽钢,底部槽钢两侧外壁上通过螺栓安装有弯梁,且两个弯梁顶部外壁上通过螺栓安装有顶部槽钢,底部槽钢顶部外壁上通过螺栓安装有中部端顶板,且中部端顶板顶部外壁通过螺栓与顶部槽钢呈固定连接,中部端顶板背面外壁一侧通过螺栓安装有内法兰,中部端顶板正面外壁一侧通过螺栓安装有外法兰,且内法兰一端外壁与外法兰一端外壁之间留有空腔。本发明的有益效果本发明工艺简单,在现有工艺基础上添加了密封胶,提高风道的密封效果,延长风道的使用寿命,而在使用时,密封胶具有拉伸强度高及很好的弹性、耐磨性等,可以提高内外法兰连接处的使用寿命。
