Abstract
Disclosed is a control valve of an exhaust system. The control valve comprises a valve seat, a valve cover and an elastic part. The valve cover can rotate relative to the valve seat. The elastic part presses the valve cover in an abutting mode. The valve seat is provided with a first support part and an opening. The valve cover is provided with a second support part and a cover body covering the opening. The control valve further comprises a thermal insulation shield covering the elastic part. Compared with the prior art, according to the control valve, the influence of high temperature on the elastic part is reduced by additionally arranging the thermal insulation shield, thus common materials can be selectively used for the elastic part in a replaceable mode, and the cost is reduced greatly.
Description
Technical field
The present invention relates to the control valve of a kind of gas extraction system for motor vehicles.
Background technology
Exhaust noise is one of main source of motor vehicles noise, and reducing exhaust noise is to reduce car
The main path of noise.When the electromotor (gasoline engine or diesel engine) of motor vehicles works, meeting
Due to present in gas extraction system exhaustor, acoustic filter, exhaust gas filter etc. and produce certain back pressure,
This back pressure generally changes with the rotation speed change of electromotor.Back pressure is for the noise of vehicle, electromotor
The aspect such as power and moment of torsion has a direct impact, on the one hand, during engine speed height, and back pressure is relatively big, row
The noise produced in gas system is less, i.e. acoustic efficiency is fine, but owing to back pressure itself can consume necessarily
Power, so the power of electromotor and moment of torsion can be affected, and and then affect fuel efficiency；Separately
On the one hand, when engine speed is low, back pressure is less, situation is contrary, making an uproar of the generation in gas extraction system
Sound is very big, i.e. acoustic efficiency is poor, but the power of electromotor and moment of torsion are impacted less, and fuel efficiency is high.
In common vehicle exhaust system, both the above situation is likely to occur.
The control valve of conventional exhaust systems generally comprises valve seat, valve gap and torsion spring etc..In use,
Because torsion spring can be exposed in aerofluxus, torsion spring can be produced impact when delivery temperature is higher.At present,
High temperature resistant spring depends on import and relatively costly (accounting for more than the 50% of valve cost) more.
Summary of the invention
It is an object of the invention to provide a kind of control possessing heat insulating function and lower-cost gas extraction system
Valve.
For achieving the above object, the present invention adopts the following technical scheme that the control valve of a kind of gas extraction system,
It includes valve seat, the valve gap that can rotate compared to described valve seat and compresses the elasticity of described valve gap
Part, described valve seat is provided with the first supporting part and opening, and described valve gap is provided with the second supporting part and screening
Keeping off the lid of described opening, described control valve also includes shade heat shield on described elastic component.
As further improved technical scheme of the present invention, described elastic component is torsion spring, and described torsion spring includes
Winder, the first pressure section extended from one end of described winder and from another of described winder
The second pressure section that end extends, wherein said first pressure section is pressed on respectively with described second pressure section
On described first supporting part and described second supporting part.
As further improved technical scheme of the present invention, described control valve be provided through described winder and
It is fixed on the support shaft on described first supporting part and described second supporting part.
As further improved technical scheme of the present invention, described heat shield is fixed on described second supporting part
On.
As further improved technical scheme of the present invention, described heat shield is welded on described second supporting part
On.
As further improved technical scheme of the present invention, described heat shield is cuboid, and it is provided with collecting
The receiving portion of described elastic component.
As further improved technical scheme of the present invention, described accommodation section is provided with heat-barrier material or heat insulation
Medium.
Compared to prior art, the present invention reduces the high temperature impact on elastic component by increasing heat shield, from
And make elastic component can select common material as an alternative, significantly reduce cost.
