▎ 摘　　要

NOVELTY - The device has a hoop belt whose two ends are provided with an ear part design connecting piece. The hoop belt is installed on an outer ring of a graphene gasket (2). A cylinder opening of a main pipe cylinder is provided with a male pipe convex rib (5). A top end of the main pipe conveyor rib and a top end is embedded in the graphene gaskets. The top of the male pipe is inserted into a female pipe cylinder body (6). USE - Connecting device embedded with graphene gasket for use in commercial vehicle post-processing system such as diesel oxidation catalyst, diesel particulate filter and selective catalytic reduction (SCR). ADVANTAGE - The connecting device adopts ear part design connecting piece, the ear portion design connecting portion and the outer hexagon bolt are completely matched, it can prevent the bolt and nut and the whole hoop from loosening. The structure of the double convex rib replaces the common flange structure, reduces the whole weight of the connecting device, and reduces the manufacturing cost of the device.
