Description
Technical field
The utility model is related to technical field of automobile accessories, and in particular to a kind of connection group for automobile exhaust system
Part.
Background technology
Currently, the connection type between each part of automobile exhaust system has:(1) it is respectively welded on two parts to be connected
Face-flange, then gasket is added between two flanges, and fastened by screw bolt and nut, shortcoming exists existing for the method
In:One is the leakproofness between pipeline relies on gasket, but usually used rubber seal is lined with service life, will produce old
Change, is deteriorated for a long time using rear sealing performance, influences the normal operation of gas exhaust piping.The second is the fitting surface of face-flange and
Welding surface is not easy to identify, and when assembly is easy to mistake, and " wrongly installed ", " neglected loading " phenomenon occurs, influences product quality.(2) two parts it
Between by spherical flange or clamp connection, be disadvantageous in that existing for the method:Pipeline leakproofness is difficult to be guaranteed.
Invention content
The purpose of this utility model is to provide a kind of connection component for automobile exhaust system, has good seal performance,
Convenient for identifying the advantage of fitting surface and welding surface.
To achieve the above object, the technical solution adopted in the utility model is:A kind of connection for automobile exhaust system
The side disk of component, admission line and outlet pipe respectively with first flange disk, second flange disk is welded, first flange disk and
Connecting hole for connection bolt to be arranged is offered on second flange disk and for the first and second through-hole of exhaust, admission line, the
One, two through-holes are connected to outlet pipe constitutes exhaust passage;First through hole on first flange disk is stepped hole, second flange disk
On the second through-hole outer rim to being extended with flange collar, the internal diameter one of the internal diameter of flange collar and the second through-hole at the bench port of first through hole
It causes, the small-bore sector hole diameter of first through hole is consistent with the caliber of admission line, outlet pipe, the large aperture sector hole diameter of first through hole
It coincide with flange collar outer diameter.
The advantageous effect generated using above-mentioned technical proposal is:In flange collar and first flange disk on second flange disk
Stepped hole constitutes grafting against cooperation, is solved from structure using the sealing between each part of flanged joint automobile exhaust system
Problem, and the design logo of stepped hole and flange collar is strong, convenient for the identification of fitting surface and welding surface when assembly, advantageously reduces life
During production the problem of " wrongly installed ", " neglected loading ", and then it can improve product quality and production efficiency.

Specific implementation mode
A kind of connection component for automobile exhaust system, as shown in figures 1 to 6, admission line A and outlet pipe B respectively with
The side disk welding of first flange disk 10, second flange disk 20 opens up on first flange disk 10 and second flange disk 20 useful
In the connecting hole 11,21 of setting connection bolt and for the first and second through-hole 12,22 of exhaust, admission line A, the first and second through-hole
12,22 are connected to composition exhaust passage with outlet pipe B;First through hole 12 on first flange disk 10 is stepped hole, second flange
The outer rim of the second through-hole 22 on disk 20 is to being extended with flange collar 23, the internal diameter of flange collar 23 and second at the bench port of first through hole 12
The internal diameter of through-hole 22 is consistent, and the small-bore sector hole diameter of first through hole 12 is consistent with the caliber of admission line A, outlet pipe B, and first
The large aperture sector hole diameter and 23 outer diameter of flange collar of through-hole 12 coincide.In flange collar 23 and first flange disk 10 on second flange disk 20
Stepped hole constitutes grafting against cooperation, ensure that the sealing problem between each part of automobile exhaust system, and stepped hole and flange collar
23 design logo is strong, convenient for assembly when fitting surface and welding surface identification, advantageously reduce in production process " wrongly installed ",
The problem of " neglected loading ", and then can improve product quality and production efficiency.
To ensure the leakproofness of junction, the step surface of the first through hole 12 and the end face of flange collar 23 are neighbouring or are bonded.
It is equipped with to be further ensured that pipeline leakproofness, between the first flange disk 10 being bonded to each other and second flange disk 20 close
Packing 30, gasket 30 are set in annular shape in flange collar 23, for convenience of assembling, and ensure the firm of connection, gasket 30
Ontology has protruded out protrusion 31 to ring core side, the end of protrusion 31 and the outer wall of flange collar 23 against.
The arrangement specifically, protrusion 31 is centrosymmetric in the circumferential direction of gasket 30.
More specific scheme is, the first and second two ring flanges 10,20 assume diamond in shape plate, and the four corners of plate face are equipped with
