Description
Technical field
This utility model relates to a kind of structure that seals, a kind of catalyst converter and the sealing structure of supercharger connection.
Background technology
Vehicle Emission is the big factor that restriction domestic automobile is cracked the international market.Domestic automobile discharge is the most up to standard
Main cause is two aspects, and one is that electromotor raw emissions pollutant load is higher, and two is that catalytic device working effect is undesirable.When
When sealing between catalytic converter assembly and supercharger is not tight, it will cause the harm such as on the low side, the gas leakage of operating temperature, cause catalysis
Changing effect is undesirable.
Current sealing between catalytic converter assembly and supercharger realizes mainly by gasket seal.As shown in figure, its principle
Be back cushion sheet convex tendon resilience contact realize between catalytic converter assembly and supercharger sealing.Booster flange, catalyst converter
Assembly flange, the inwall of gasket seal need alignment, and otherwise the air-flow in equipment deflation will cause pad to damage, and increases installation
Difficulty.Simultaneously as the temperature of supercharger outlet is higher, the deformation comparison of supercharger and catalytic converter assembly flange is big, docking
Face produces sliding sometimes, causes sealing problem still to can not get solving.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and solve between catalytic converter assembly and supercharger is close
Envelope problem, devises a kind of catalytic converter assembly and the novel sealing structure of supercharger connection, reduces while installing operation easier,
Enhance sealing effectiveness.
To achieve the above object of the invention, it is provided that the sealing structure that a kind of catalytic converter assembly and supercharger connect, including catalysis
Device assembly flange and booster flange, described catalytic converter assembly flange connection surface sets multiple convex tendon and groove, convex tendon and groove
Spaced apart, described convex tendon and channel section are shaped as rectangle, corresponding catalytic converter assembly method on described booster flange joint face
Blue joint face convex tendon and groove arrange groove and the convex tendon of respective shapes；Innermost circle convex tendon in described catalytic converter assembly flange convex tendon
Thickness is more than remaining convex tendon thickness, and in described booster flange convex tendon, innermost circle convex tendon thickness is more than remaining convex tendon thickness.Make
Flange contact facings forms labyrinth passage.
Preferably, described catalytic converter assembly flange innermost circle convex tendon thickness is more than 5mm.
Preferably, described booster flange innermost circle convex tendon thickness is more than 5mm.
Preferably, on described catalytic converter assembly flange, convex tendon thickness in addition to innermost circle convex tendon is equal.
Preferably, described convex tendon spacing in addition to innermost circle convex tendon is equal.
Preferably, described booster flange keeps consistent and inwall pair with the minimum diameter aperture of catalytic converter assembly flange
Together.
Preferably, described booster flange uses Langaloy to make.
Preferably, the material of described catalytic converter assembly flange is rustless steel.
This sealing structure is with the groove of booster flange and the convex tendon of catalytic converter assembly flange, aligning inner, phase
Form indenting coupling formula mutually and assemble sealing, as shown in Figure 3 and Figure 4.Then booster flange and catalyst converter are total
Flange is become to be inter-connected via a bolt joint.
The sealing structure that catalytic converter assembly of the present utility model and supercharger connect, by giving up gas extraction system pad, shape
Become the assembling of coupling formula to simplify installation procedure, then increase the thickness of the inner side first lap convex tendon of flange, reduce high-temperature gas and lead to
The impact that the deformation of out-of-date material produces.
The beneficial effects of the utility model are can effectively to simplify the connection of catalytic converter assembly and supercharger, decrease high temperature
The poorly sealed problem that gas produces, and from structure is arranged and material selects, reached to increase the mesh of system reliability
's.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
The sealing structure connected according to a kind of catalytic converter assembly shown in Fig. 3 to Fig. 5 and supercharger, including catalytic converter assembly
Flange 5 and booster flange 4, described booster flange 4 uses Langaloy to make, and catalytic converter assembly flange 5 uses rustless steel
Material makes, and increases catalytic converter assembly flange 5 and the stability of booster flange 4.
Multiple convex tendon and groove, convex tendon and groove is set spaced apart on described catalytic converter assembly flange 5 joint face, described convex
Muscle and channel section are shaped as rectangle, on described booster flange 4 joint face corresponding catalytic converter assembly flange 5 joint face convex tendon and
Groove arranges groove and the convex tendon of respective shapes.After flange inner wall alignment is installed, two dish flanges mutually form interlocking
Coupling formula assembled sealing, gas is by after these labyrinth passages, and air pressure is gradually lowered, and reduces the risk of gas leakage.
The number of convex tendon and groove is the most, and the passage of gas is the most complicated, and the risk of gas leakage is the lowest.
On catalytic converter assembly and booster flange contact surface, innermost circle convex tendon 7,8 thickness is more than remaining convex tendon thickness, and greatly
In 5mm, it is possible to effectively prevent the material deformation that high temperature gas flow admittance causes in equipment.
On catalytic converter assembly and booster flange contact surface, the convex tendon thickness in addition to innermost circle convex tendon is equal so that mutually
Between coupling formula assembling shape rule, easily align, reduce workman and connect the difficulty of operation.
Below the preferred embodiment created this utility model is illustrated, but this utility model is created not
Being limited to described embodiment, those of ordinary skill in the art are all right on the premise of this utility model creative spirit
Making modification or the replacement of all equivalents, these equivalent modifications or replacement are all contained in the model that the application claim is limited
In enclosing.
