Description
Technical field
The utility model relates to the auto parts and components field, particularly a kind of ternary catalyst purifier.
Background technique
Present automobile ternary catalyst purifier all is by cylindrical shell, the end awl, and liner and carrier are formed, and carrier adopts stupalith more, and the end awl is made with the mode that the ternary catalyst purifier cylindrical shell welds.And the end awl is to adopt the mode of die stamping stretching to make.Adopt cylindrical shell to close up to the protection of liner and add wire netting, and the end awl that designs different shapes is protected liner at the air flow inlet end.This ternary catalyst purifier cost height, tightness are difficult to ensure that appearance looks elegant is relatively poor, produces constant error worker often, mistakes inefficiency.
The model utility content
The technology that the utility model need solve is not corroded to reach the better protection liner for topic provides a kind of ternary catalyst purifier, and the purpose of manufacturing efficiency is provided.
In order to solve the problems of the technologies described above the technical solution of the utility model be, a kind of ternary catalyst purifier is provided, comprise cylindrical shell, be arranged on the carrier in the cylindrical shell, be provided with liner between carrier and the cylindrical shell; The both sides of described cylindrical shell are provided with step-like inlet end awl and step-like exhaust end awl.
Described inlet end awl comprises first step and second step, and the direction of the tapering of described first step and second step is identical, and is provided with the cylinder of transition between first step and the second step.
The bus of described first step and the angle of tubular axis are 45 degree, and the bus of second step and the angle of tubular axis are 44 degree.
Described exhaust end awl comprises the 3rd step and the 4th step, and described the 3rd step is identical with the direction of the tapering of the 4th step, and is provided with the cylinder of transition between the 3rd step and the 4th step.
The bus of the 3rd step of described exhaust end awl and the angle of tubular axis are 46 degree, and the bus of the 4th step and the angle of tubular axis are 45 degree.
The utility model compared with prior art, the both sides of cylindrical shell are provided with step-like inlet end awl and step-like exhaust end awl, the good sealing effect that cylindrical shell and end are bored is simple in structure, with low cost, easily manufactured.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details;
Fig. 1 is the utility model structural representation;
In Fig. 1,1, cylindrical shell, 2, liner, 3, carrier, 4, the inlet end awl, 5, the exhaust end awl, 6, first step, 7, second step, the 8, the 3rd step, the 9, the 4th step.
Embodiment
As shown in Figure 1,1, a kind of ternary catalyst purifier, comprise cylindrical shell 1, be arranged on the carrier 3 in the cylindrical shell 1, be provided with liner 2 between carrier 3 and the cylindrical shell 1, the both sides of described cylindrical shell 1 are provided with step-like inlet end awl 4 and step-like exhaust end bores 5.
Described inlet end awl 4 comprises first step 6 and second step 7, and described first step 6 is identical with the direction of the tapering of second step 7, and is provided with the cylinder of transition between first step 6 and the second step 7.
The angle of the axis of the bus of described first step 6 and cylindrical shell 1 is 45 degree, and the angle of the bus of second step 7 and cylindrical shell 1 axis is 44 degree.
Described exhaust end awl 5 comprises the 3rd step 8 and the 4th step 9, and described the 3rd step 8 is identical with the direction of the tapering of the 4th step 9, and is provided with the cylinder of transition between the 3rd step 8 and the 4th step 9.
The bus of the 3rd step 8 of described exhaust end awl 5 and the angle of cylindrical shell 1 axis are 46 degree, and the bus of the 4th step 9 and the angle of tubular axis are 45 degree.
Be step-like end awl at inlet end awl 4 and exhaust end awl 5, avoid the deflation of the waste gas that produces in the automobile running to liner 2, protective lining 2 intact, adopt staircase structural model, the tail gas that motor is discharged enters in the cylindrical shell 1 from inlet end awl 4, air-flow can directly not blow on the liner 2, step-like end awl can protective lining 2 not by deflation, strengthen the durability of catalyst converter; And inlet end awl 4, exhaust end awl 5 and cylindrical shell 1 are spun into one and form, the end awl is an one with cylindrical shell 1, there is not the Welding Problems of end awl and cylindrical shell 1, thereby the weld seam failure welding can not occurs and the problem that occurs revealing yet, so the good sealing effect of cylindrical shell 1 and end awl; This kind structure has guaranteed the fluency of exhaust, and to not influence of exhaust back pressure, engine performance can not be affected yet.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
