Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, seal nipple of the present utility model, including the left side for being provided with primary sealing area 11
Joint 1 and the right connector 2 for being provided with secondary sealing area 21, described primary sealing area 11 are provided with the boss 12 of cylinder, described
Secondary sealing area 21 is provided with the mounting groove 22 matched with boss 12, and described primary sealing area 11 is provided with annular groove 3, described
Secondary sealing area 21 is provided with the annular flange flange 4 matched with annular groove 3, and at described 22 opening of mounting groove, side wall is provided with draw-in groove 5,
The first sealing ring 6 is provided with described draw-in groove 5, in described annular groove 3 and the side of boss 12 is located remotely from and is provided with extruding
Annular flange flange 4 is so that the annular projection 7 of 5 the first sealing ring of deformable squeeze 6 of draw-in groove, is carried out by round platform and mounting groove 22 substantially close
