Pipe 12 is bend pipe structure so that exhaust butterfly valve arrange from booster position farther out, according to current arrangement can not will
Butterfly valve is as close to booster so that the retardation efficiency of exhaust brake is low, when vehicle is frequent or crosses for a long time using brake
When being braked, brake hub can heat up, and directly affect the security of vehicle traveling, reduce the life-span of brake system.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form
Technology.
Utility model content
The purpose of this utility model is to provide a kind of laying structure of simple and reasonable engine exhaust butterfly valve, is somebody's turn to do
The laying structure of engine exhaust butterfly valve will be vented butterfly valve by butterfly valve cushion block and be arranged close to booster, improve retardation efficiency.
Butterfly valve is vented simultaneously close to booster, reduces tension of the butterfly valve to booster so that the more adduction of vehicle gas exhaust piping arrangement
Reason, compact, the failure of reduction booster and blast pipe.
To achieve the above object, the utility model provides a kind of laying structure of engine exhaust butterfly valve, including：Supercharging
Device, it increases air inflow by compressed air, and the booster has exhaust gas inlet and waste gas outlet；Butterfly valve is vented, it has
Exhaust gas intake port and air exit；And butterfly valve cushion block, its one end have booster adpting flange, for useless with the booster
Gas outlet connection；The other end of the butterfly valve cushion block has exhaust butterfly valve mounting surface, for passing through clip and the exhaust butterfly valve
Exhaust gas intake port connects.
Preferably, in above-mentioned technical proposal, butterfly valve cushion block is tubulose, and the waste gas of the caliber of its one end and the booster goes out
Mouth adaptation, the caliber of the other end are adapted to the exhaust gas intake port of the exhaust butterfly valve.
Preferably, in above-mentioned technical proposal, exhaust butterfly valve is arranged between the booster and catalytic muffler.
Compared with prior art, the utility model has the advantages that：The laying structure of the engine exhaust butterfly valve
Butterfly valve will be vented by butterfly valve cushion block to arrange close to booster, improve retardation efficiency.Butterfly valve is vented close to booster simultaneously, is subtracted
Tension of few butterfly valve to booster so that more reasonable, compact, reduction booster and the blast pipe of vehicle gas exhaust piping arrangement
Failure.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Fig. 2 provided according to the laying structure of the engine exhaust butterfly valve of the utility model embodiment
A kind of structure for supporting exhaust butterfly valve, greatly improve the retardation efficiency of engine exhaust and brake.The engine exhaust butterfly valve
Laying structure specifically includes：Booster 21, butterfly valve cushion block 22 and exhaust butterfly valve 23, wherein, one end of butterfly valve cushion block 22 and increasing
Depressor 21 is connected, and the other end is connected with exhaust butterfly valve 23, and the connection both ends of butterfly valve cushion block 22 meet the He of booster 21 by reducing
The matching requirements of butterfly valve 23 are vented, so as to which butterfly valve will be vented as far as possible close to booster by butterfly valve cushion block, shorten butterfly valve to increasing
Depressor body distance, retardation efficiency is lifted, reduces the replacing of brake, it is cost-effective.In addition, exhaust butterfly valve is close to booster,
Tension of the butterfly valve to booster is reduced, reduces the failure of booster and blast pipe so that vehicle gas exhaust piping is arranged more
Rationally, it is compact, reduce and engine part (booster, blast pipe) is damaged.
Specifically, booster 21 has exhaust gas inlet and waste gas outlet.Booster 21 by compressed air come increase into
Tolerance.It is to be entered using the waste gas inertia impulsive force of engine discharge by exhaust gas inlet to promote the turbine in turbine room, turbine
Coaxial impeller is driven again, the air that impeller force feed is sent by air cleaner pipeline, is allowed to supercharging and is entered cylinder.Work as engine
Rotating speed increases, and the waste gas velocity of discharge also synchronously increases with secondary speed, and impeller just compresses more air and enters cylinder, air
Pressure and density increase more fuel that can burn, the corresponding rotating speed for increasing fuel quantity and adjusting engine, it is possible to increase
The power output of engine.
Exhaust butterfly valve 23 is arranged between booster 21 and catalytic muffler, has exhaust gas intake port and air exit, when making
During with exhaust brake, exhaust butterfly valve 23 is closed, separates exhaust gas intake port and air exit, increases the resistance of gas extraction system, so as to
Resistance is added to automobile, reduces the speed of vehicle, has reached the purpose of service brake, lifts the driving safety of automobile.
Butterfly valve cushion block 22 is tubulose, and the caliber of its one end is adapted to the waste gas outlet of booster 21, and is connected with booster
Acting flange 24, for being connected with the waste gas outlet of booster 21；The caliber of the other end of butterfly valve cushion block 22 and exhaust butterfly valve 23
Exhaust gas intake port is adapted to, and with exhaust butterfly valve mounting surface 25, for being connected by exhaust gas intake port of the clip with being vented butterfly valve 23, butterfly
The connection both ends of valve pad block 22 meet booster 21 and the exhaust matching requirements of butterfly valve 23 by reducing, so that will by butterfly valve cushion block
Butterfly valve is vented as far as possible close to booster, butterfly valve is shortened to booster body distance, lifts retardation efficiency, reduce brake
Change, it is cost-effective.In addition, exhaust butterfly valve reduces tension of the butterfly valve to booster, reduces booster and row close to booster
The failure of tracheae so that vehicle gas exhaust piping is arranged more reasonable, compact.
To sum up, the laying structure of the engine exhaust butterfly valve will be vented butterfly valve by butterfly valve cushion block and be arranged close to booster,
Improve retardation efficiency.Butterfly valve is vented simultaneously close to booster, reduces tension of the butterfly valve to booster so that vehicle blast pipe
More reasonable, compact, the failure of reduction booster and blast pipe of road arrangement.
The foregoing description to specific illustrative embodiment of the present utility model is to illustrate and the purpose of illustration.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
