The invention relates to a bypass valve used for a turbosupercharger, in particular to a bypass valve with an anti-rotation structure. The bypass valve comprises a valve plate assembly and a connecting arm connected to the valve plate assembly; one end of the connecting arm is connected with a rotating shaft, and the bypass valve is characterized in that a gap is formed in the other end of the connecting arm, a boss is arranged on the valve plate assembly, and is arranged in the gap, and the boss and the gap are in face contact. The bypass valve is simple and reasonable in structure, and a valve plate of the bypass valve rotates around the axis of the valve plate and can be limited to be smaller; more importantly, due to the surface contact between the limiting characteristics, the contact stress is greatly reduced, and therefore the abrasion of the limiting characteristics is greatly reduced, the limiting precision can be kept more durable, and the failure probability of the bypass valve is greatly reduced.
Description
Technical field
Patent of the present invention is related to a kind of bypass valve for turbocharger, the particularly bypass valve with anti-rotation structure.
Background technology
Turbocharger is a kind of device for increasing engine charge pressure.The supercharger is using the useless of electromotor
Gas energy drives turbine rotation, then drives the compressor impeller that couples coaxial with turbine to rotate and carrys out compressed air, by
Motivation provides more highdensity compressed air, realizes increasing the purpose of engine output.The turbocharger is usual
With following structure, the turbine cylinder of turbine is surrounded；Support the middle casing of rotary shaft；Surround the compressor of compressor impeller
Housing.
Additionally, in the turbocharger, exhaust gas by-pass valve is generally there also is provided, for preventing because exhaust gas pressure is too high
And cause engine charge pressure too high.The construction of the exhaust gas by-pass valve is to make exhaust gas inlet side of the waste gas from turbine cylinder
Face is discharged to turbine outlet via the bypass path that opening and closing is controlled by exhaust gas by-pass valve, so as to reduce the waste gas for being supplied to turbine
Energy, the output pressure that compressor is reduced to reduce the rotating speed of turbine and impeller reduce the admission pressure of electromotor.
As shown in Figures 1 and 2, in existing turbocharger, on turbine case 11, there is bush hole, for placing bushing
12, rotary shaft 14 and the 12 coaxial assembling of bushing of bypass valve 13.There is rocking arm 15 in 14 other end of rotary shaft of the bypass valve 13
With 14 rigid attachment of the rotary shaft.The rocking arm 15 can transmit the power transmitted from compressor or other devices to the bypass
Valve 13, forces the bypass valve 13 to rotate around the rotary shaft 14 of itself, so as to control the opening and closing of bypass valve 13.
Existing bypass valve assembly as shown in Figure 3, wherein comprising rotary shaft 21, the rotary shaft is installed on link arm 22
In hole 23, the axle 25 on valve block 24 is connected in the link arm 22 in the hole 26 of its plane, and pad 27 is used to limit
The motion axially of valve block 24.There is radial clearance between the hole 26 of the axle 25 and link arm 22 of the bypass valve valve block 23, institute
State and have axial gap between the step surface 28 on valve block 24 and linking arm 22.
For the bypass valve shown in Fig. 3,4, when bypass valve is opened, due to being impacted by the air-flow from bypass passageways
And the impact of vibration, bypass valve valve block 23 can occur the rotation around own axes.Thus cause valve block 23, link arm 22 and
Wear and tear between pad 24, abrasion can cause axial gap and radial clearance to become big, cause then bypass valve fall when closing
In correct scope, or even fall in the aperture of bypass passageways.Simultaneously as gap increase causes the motion amplitude of bypass valve to increase
Also result in greatly the surface Fast Wearing that bypass valve is supported on turbine case.When more serious, sharp wear can cause to bypass valve components
In fracture or turbine case, material is peeled off, so that bypass valve complete failure, supercharger cisco unity malfunction.For natural gas engine
For machine, as in volute, temperature is higher for diesel engine, while the time that bypass valve is opened can be longer, bypass valve loses
The probability of effect can be significantly increased.
In order to solve above-mentioned wear problem, the scheme described in patent documentation 1 can be adopted, i.e., on the pad of bypass valve
Increase the limit features perpendicular to pad.But, as such limit features are limiting product when bypass valve valve block rotates
Raw is linear contact lay, and caused contact stress can cause for the abrasion between two spacing parts than more serious than larger,
So as to have influence on spacing precision, it could even be possible to there is fracture failure.Simultaneously as limit features should not be extended outwardly past
Long, which is to the rotationally constrained not accurate enough of bypass valve valve block.
The content of the invention
The present invention is directed to the problems referred to above, there is provided a kind of bypass valve with anti-rotation structure, the bypass valve can be more accurate
The rotation of bypass valve valve block is limited, while the abrasion of limit features can be reduced, spacing long-term reliability and bypass valve is improved
The life-span of element.
According to technical scheme：A kind of bypass valve with anti-rotation structure, including valve block component and be connected to described
Linking arm on valve block component, described linking arm one end connect rotary shaft；It is characterized in that：The linking arm other end is provided with scarce
Mouthful, valve block component is provided with boss, and the boss is placed in the breach, is contacted for face between boss and breach.
As a further improvement on the present invention, the valve block component includes valve block, pad, the centre of gyration of valve block mounting surface
The bearing pin of integrally connected is formed, is sheathed on linking arm on the bearing pin, pad tight fit connection is on the step surface of bearing pin.
As a further improvement on the present invention, the boss is integrally connected on valve block.
As a further improvement on the present invention, the boss is integrally connected on pad.
As a further improvement on the present invention, the boss and the sidepiece contact surface of breach are plane or curved surface.
As a further improvement on the present invention, the boss two sides and valve block surface be at an acute angle or obtuse angle.
The method have technical effect that：Present configuration is simple, reasonable, and bypass valve valve block can around the rotation of own axes
With confined less.Importantly, due to contacting in face between limit features, its contact stress is greatly reduced, therefore limit
Position feature abrasion can greatly reduce, thus spacing precision can also keep it is more longlasting, the probability of bypass valve defective is even more
Can greatly reduce.
