Abstract
The utility model discloses an exhaust pipe for automobile, include: inner tube and outer tube, wherein: the inner tube sets up reserves gapped both ends confined at a distance from the chamber between the inner wall of the outer wall of the inside of outer tube and inner tube and outer tube, the inner tube passes through the interior wall connection of flexible connectors and outer tube, and it has a plurality of wash ports that switch on with the outer tube inner chamber to distribute on the wall of inner tube, outer bore of pipe is decreased progressively to the other end by one end, and the minimum internal diameter of outer tube is greater than the diameter of inner tube, one side of outer tube is equipped with the water drainage branch pipe who feeds through with the outer tube inner chamber, and water drainage branch pipe lies in near one side of the biggest internal diameter end on the outer tube and lies in the pinacoidal least significant end of outer tube. The utility model discloses avoided the problem that liquid solidifies in exhaust duct, solved the blast pipe and blockked up because of engine exhaust liquefaction low temperature solidifies the exhaust pipe who causes, leaded to that engine exhaust is unable to discharge, the unable problem that starts of engine.
Description
Technical field
The utility model relates to pipe fitting processing technique field, particularly relates to a kind of automobile exhaust pipe.
Background technique
Automobile is very universal, becomes the traffic tool indispensable in life.The traveling of automobile needs motor to provide power, and motor carry out gasoline combustion after waste gas need to be discharged by outlet pipe.
And in the process of waste air, because engines tail gas liquefaction can produce liquid, and these liquid residues are in outlet pipe, solidify when low temperature, thus make the pipeline of vent systems blocked, the tail gas of motor cannot be discharged, and cause motor to start, vehicle cannot normally travel.
Model utility content
Based on the technical problem that above-mentioned background technology exists, the utility model proposes a kind of automobile exhaust pipe, the problem that liquid solidifies in exhaust passage can be avoided.
The utility model proposes a kind of automobile exhaust pipe, comprising: inner and outer tubes, wherein:
Interior pipe is arranged on the inside of outer tube and is reserved with the separate space of gap closed at both ends between the outer wall of interior pipe and the inwall of outer tube; Interior pipe is connected with the inwall of outer tube by Flexible Connector, the wall of interior pipe is distributed with weep hole that is some and outer tube bore conducting;
The internal diameter of outer tube is successively decreased to the other end by one end, and outer tube minimum diameter is greater than the diameter of interior pipe; The side of outer tube is provided with the branch drain be communicated with outer tube bore, and branch drain is positioned at the side of maximum inner diameter end on the outer tube and is positioned at the least significant end of outer tube axial plane.
Preferably, waste pipe arm is communicated with end with outer tube and is set to horn mouth.
Preferably, the maximum inner diameter end of outer tube is near automobile tail pipe.
Preferably, the outlet end of branch drain is passed by automobile tail pipe and extends the outside of automobile tail pipe.
Preferably, the drain opening of branch drain is towards ground.
Preferably, outer tube is around property pipe.
Preferably, interior pipe is bypass tube.
In the utility model, interior pipe is arranged on the inside of outer tube and is reserved with the separate space that gap forms closed at both ends between the outer wall of interior pipe and the inwall of outer tube; Interior pipe is connected with the inwall of outer tube by Flexible Connector, and arranging of Flexible Connector can make automobile in the process of moving, produces relative vibration between interior pipe and outer tube; The wall of interior pipe is distributed with the weep hole of several and outer tube bore conducting; When automobile is when being vented, tail gas liquefaction and produce liquid by the relative vibration effect of inner and outer tubes and be thrown toward inner tubal wall, enters in the separate space between interior pipe and outer tube by the weep hole on inner tubal wall;
Due to, the internal diameter of outer tube is successively decreased to the other end by one end, and the side of outer tube is provided with the branch drain be communicated with outer tube bore, and branch drain is positioned at the side of maximum inner diameter end on outer tube; Therefore the liquid being positioned at separate space can be pooled to branch drain and be discharged by branch drain, avoids liquid at internal tube frozen plug gas exhaust piping.
In sum, the utility model avoids the problem that liquid solidifies in exhaust duct, solves the gas exhaust piping blocking that outlet pipe causes because engines tail gas liquefaction low temperature solidifies, causes motor exhaust to discharge, the problem that motor cannot start.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of automobile exhaust pipe that the utility model proposes.
Embodiment
Below, by specific embodiment, the technical solution of the utility model is described in detail.
As shown in Figure 1, Fig. 1 is the structural representation of a kind of automobile exhaust pipe that the utility model proposes.
With reference to Fig. 1, a kind of automobile exhaust pipe that the utility model embodiment proposes, comprising: interior pipe 1 and outer tube 2,
Interior pipe 1 is bypass tube, and the two ends of interior pipe 1 are connected to form gas exhaust piping with connecting engine discharge manifold and automobile tail pipe respectively, interior pipe 1 be arranged on the inside of outer tube 2 and between the outer wall of interior pipe 1 and the inwall of outer tube 2, be reserved with the separate space 3 of gap closed at both ends; Interior pipe 1 is connected with the inwall of outer tube 2 by Flexible Connector 5, utilizes the elasticity of Flexible Connector 5 to make automobile in the process of moving, produces relative vibration between interior pipe 1 and outer tube 2; The wall of interior pipe 1 is distributed with weep hole 11 that the is some and conducting of outer tube 2 inner chamber; When automobile is when being vented, tail gas liquefaction and produce liquid by the relative vibration effect of interior pipe 1 and outer tube 2 and be thrown toward interior pipe 1 wall, is entered in the separate space 3 between interior pipe 1 and outer tube 2 by the weep hole 11 on interior pipe 1 wall.
Outer tube 2 is around property pipe, and the internal diameter of outer tube 2 is successively decreased to the other end by the one end near automobile tail pipe 6, and outer tube 2 minimum diameter is greater than the diameter of interior pipe 1; The side of outer tube 2 is provided with the branch drain 4 with outer tube 2 inner space, and branch drain 4 is positioned at the side of maximum inner diameter end on the outer tube 2 and is positioned at the least significant end of outer tube 2 axial plane; Waste pipe arm 4 is communicated with end with outer tube 2 and is set to horn mouth, and the outlet end of branch drain 4 is passed by automobile tail pipe 6 and extends the outside of automobile tail pipe 6, and makes the drain opening of branch drain 4 towards ground; Therefore the liquid being positioned at separate space 3 can be pooled to branch drain 4 and be discharged by branch drain 4, avoids liquid at interior pipe 1 solidified inside blocking gas exhaust piping.
As from the foregoing, the utility model avoids the problem that liquid solidifies in exhaust duct, solves the gas exhaust piping blocking that outlet pipe causes because engines tail gas liquefaction low temperature solidifies, causes motor exhaust to discharge, the problem that motor cannot start.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
