The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1 to 6, the present utility model relates to a connecting and sealing joint for an automotive pipeline 5, which comprises a connecting body 1, end covers 2 positioned at two ends of the connecting body 1, and a spherical sealing ring 3 positioned between the end covers 2 and the connecting body 1; the connecting body 1, the end cover 2 and the spherical sealing ring 3 are respectively provided with a channel 7 for the pipeline 5 to pass through; the end cover 2 is detachably connected with the connecting body 1; the connecting body 1 is formed with a connecting cavity 11 connected with the end cover 2 at both ends, and a connecting column 21 matched with the connecting cavity 11 is formed at one end of the end cover 2. In the present embodiment, the inner side wall of the connection chamber 11 is formed with an internal thread, and the outer side wall of the connection post 21 is formed with an external thread. The bottom of the connecting cavity 11 is formed with a first hemispherical mounting groove 12 matched with the spherical sealing ring 3, and the end face of the connecting column 21 is formed with a second hemispherical mounting groove 22 matched with the spherical sealing ring 3. The inner diameter of the first hemispherical installation groove 12 and the inner diameter of the second hemispherical installation groove 22 are smaller than the diameter of the spherical sealing ring 3. Through carrying out threaded connection between end cover 2 and connecting body 1, after pipeline 5 passed end cover 2 and spherical sealing washer 3, rotatory end cover 2 makes end cover 2 and connecting body 1 realize being connected, and in this process, because the internal diameter of first hemisphere mounting groove 12 and second hemisphere mounting groove 22 all is less than the diameter of spherical sealing washer 3, consequently end cover 2 and connecting body 1 can constantly extrude spherical sealing washer 3, is spherical sealing washer 3 toward the centre of sphere shrink to make spherical sealing washer 3 and pipeline 5 closely laminate and guarantee the leakproofness.
