Abstract
The utility model relates to a hemispheric end cone used for packaging catalysts. The hemispheric end cone used for packaging catalysts comprises a hemispheric shell, an air inlet connecting pipe with the equal cross section is eccentrically arranged on the hemispheric shell, and a turnup segment with the edge turning outwards is connected to the end face of the hemispheric shell. The hemispheric end cone used for packaging catalysts is simple in structure, reasonable in design, easy to manufacture and low in cost; for hemispheric end cones with one size, a straight pipe segment is replaced by the turnup segment, three-way packaging requirements for different carrier sizes are met, the size application range of the hemispheric end cone is expanded, and practicality is improved.
Description
Technical field
The utility model relates to a kind of auto parts, particularly relates to a kind of hemispherical end cone for catalyst converter encapsulation.
Background technique
At present, hemispherical end cone is the important Component of vehicle engine exhaust gas emission-control equipment, for realizing gas exhaust manifold, is connected with offgas duct with ternary catalyzing unit, ternary catalyzing unit, plays the effect of guiding waste gas circulation.
The most straight-run of pipe sections that connect of end face of existing hemispherical end cone, straight length is by welding with the housing of ternary catalyzing unit, thereby realizes the encapsulation of catalyst converter.In actual application, the size of above-mentioned hemispherical end cone straight length must be strictly corresponding with the carrier dimensions of ternary catalyzing unit, and a kind of hemispherical end of size cone can only corresponding a kind of carrier specification, if carrier dimensions variation, again beginning prod cast tool, causes development cost greatly to increase.
Summary of the invention
The purpose of this utility model is to overcome the deficiency existing in above-mentioned technology, and a kind of simple in structure, reasonable in design, reliable operation, cost is low, size the is applied widely hemispherical end cone for catalyst converter encapsulation are provided.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise hemispherical shell, on hemispherical shell, bias is provided with a prismatic air inlet tube, and the end face of described hemispherical shell is connected with the flange section of one section of outward flanging.
The utility model has the advantages that:
Simple in structure, reasonable in design, be easy to manufacture, cost is low, hemispherical end cone for a kind of size, by utilizing flange section to replace straight length, has met the ternary encapsulation of different carriers size, the size Applicable scope that has expanded hemispherical end cone, has increased practicability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
From Fig. 1-Fig. 2, the utility model comprises hemispherical shell 1, and on hemispherical shell 1, bias is provided with a prismatic air inlet tube 2, and the end face of described hemispherical shell 1 is connected with the flange section 3 of one section of outward flanging.
The flange angle of described flange section 3 is 3 °-10 °.
A kind of hemispherical end cone for catalyst converter encapsulation of the present utility model is comprised of hemispherical shell 1, air inlet tube 2 and flange section 3, air inlet tube 2 is located at a side of hemispherical shell 1, for being connected with gas exhaust manifold or offgas duct, flange section 3 is connected with the end face of hemispherical shell 1, the flange angle of flange section 3 is 3 °-10 °, flange section 3 is welded with the housing of ternary catalyzing unit, thereby realizes the encapsulation of catalyst converter.
A kind of hemispherical end for catalyst converter encapsulation of the present utility model is by utilizing flange section to replace straight length, met the ternary encapsulation of different carriers size, the size Applicable scope that has expanded hemispherical end cone, has increased practicability, simple in structure, reasonable in design, be easy to manufacture, cost is low.
