Abstract
The utility model relates to a kind of full return-pressure type automobile silencing outlet pipe.This full return-pressure type automobile silencing outlet pipe, comprise outer tube and interior webmaster, outer tube sleeve is located at outside interior webmaster, is embedded with silencing cotton layer between outer tube and interior webmaster, and described outer tube one end is provided with exhaust gas entrance, the outer tube the other end is provided with waste gas outlet, exhaust gas entrance is connected with the first interpolation pipe, and Intranet pipe box is located at outside the first interpolation pipe, and described interior webmaster is built-in with the second interpolation pipe, second interpolation pipe stretches out outer tube through after interior webmaster and silencing cotton layer, and waste gas outlet is set in outside the second interpolation pipe.The utility model structure is simple, and reasonable in design, waste gas enters Intranet tube cavity through the first interpolation pipe, air-flow mutually impacts in Intranet tube cavity, air-flow velocity is slowed down, by slowly being flowed out by waste gas outlet after the second interpolation pipe, to reach the pressure slowing down waste gas; Waste gas noise improves performance muffler after silencing cotton layer.
Description
Technical field
The utility model relates to a kind of full return-pressure type automobile silencing outlet pipe.
Background technique
Along with the fast development of China's economy, the living standard of people is also in continuous improve, and the growth of the recoverable amount of automobile in city, while facilitating the life of people's schedule, also causes great impact to social environment.Automobile noise has become the main composition part of city noise, the exhaust sound especially in car running process, and it is the Main Noise Sources of automobile.Control automobile exhaust noise and mainly use the silencing apparatus with superperformance by the combustion manner of mixed gas in rationalization's cylinder with design.At present, realize reducing automobile exhaust noise the most directly, most effective method uses exhaust silencer exactly.In order to reach the acoustic attenuation performance of silencing apparatus the best, ensure again that the least possible power loss is a present stage difficult problem in the urgent need to address simultaneously.For reducing exhaust noise, Motor Vehicle generally adopts silencing exhaust pipe, automobile silencing outlet pipe is one and matured product, its basic structure and working principle almost do not change decades, are now badly in need of a kind of novel structure, the cheap and better silencing exhaust pipe of erasure effect of more general noise reduction product.
Model utility content
For the problems referred to above, the utility model proposes a kind of full return-pressure type automobile silencing outlet pipe.
For solving this technical problem, the utility model takes following scheme: a kind of full return-pressure type automobile silencing outlet pipe, comprise outer tube and interior webmaster, outer tube sleeve is located at outside interior webmaster, silencing cotton layer is embedded with between outer tube and interior webmaster, Intranet pipe for the protection of with supporting silencing cotton layer, described outer tube one end is provided with exhaust gas entrance, the outer tube the other end is provided with waste gas outlet, exhaust gas entrance is connected with the first interpolation pipe, Intranet pipe box is located at outside the first interpolation pipe, described interior webmaster is built-in with the second interpolation pipe, second interpolation pipe stretches out outer tube through after interior webmaster and silencing cotton layer, waste gas outlet is set in outside the second interpolation pipe.Waste gas outlet and the second interpolation pipe are that concentric arranges structure.
Further, the first described interpolation pipe afterbody is provided with outlet side, and the second interpolation pipe front end is provided with inlet end, and outlet side and inlet end distribute up and down and arrange.
Further, described silencing cotton layer is high temperature resistant and glass wool layer that is good muffling effect.
Further, the second described interpolation pipe tail end is arranged with noise reduction plug.
By adopting preceding solution, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, waste gas enters Intranet tube cavity through the first interpolation pipe, air-flow mutually impacts in Intranet tube cavity, air-flow velocity is slowed down, by slowly being flowed out by waste gas outlet after the second interpolation pipe, to reach the pressure slowing down waste gas; Waste gas noise improves performance muffler after silencing cotton layer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, outer tube, 2, interior webmaster, 3, silencing cotton layer, 4, exhaust gas entrance, 5, waste gas outlet, the 6, first interpolation pipe, the 7, second interpolation pipe, 8, outlet side, 9, inlet end, 10, noise reduction plug.
Embodiment
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to the open a kind of full return-pressure type automobile silencing outlet pipe of figure 1 the present embodiment, comprise outer tube 1 and interior webmaster 2, outer tube 1 is set in outside interior webmaster 2, silencing cotton layer 3 is embedded with between outer tube 1 and interior webmaster 2, outer tube 1 one end is provided with exhaust gas entrance 4, outer tube 1 the other end is provided with waste gas outlet 5, exhaust gas entrance 4 is connected with the first interpolation pipe 6, interior webmaster 2 is set in outside the first interpolation pipe 6, interior webmaster 2 is built-in with the second interpolation pipe 7, second interpolation pipe 7 stretches out outer tube 1 through after interior webmaster 2 and silencing cotton layer 3, and waste gas outlet 5 is set in outside the second interpolation pipe 7.
First interpolation pipe 6 afterbody is provided with interpolation pipe 7 front end, outlet side 8, second and is provided with inlet end 9, and outlet side 8 and inlet end about 9 distribute and arrange, and silencing cotton layer 3 is high temperature resistant and glass wool layer that is good muffling effect, and the second interpolation pipe 7 tail end is arranged with noise reduction plug 10.
During work, waste gas is entered the inner chamber of interior webmaster 2 through the outlet side 8 of the first interpolation pipe 6 tail end by exhaust gas entrance 4, cavity volume increases, air-flow mutually impacts in Intranet tube cavity, and air-flow velocity is slowed down, and silencing cotton layer 3 absorbs the noise of waste gas simultaneously, the inlet end 9 of last air-flow through the second interpolation pipe 7 front end is discharged from waste gas outlet 5, reach the pressure slowing down waste gas, waste gas outlet 5 tail end is provided with noise reduction plug 10, absorbs the noise of waste gas further.
This full return-pressure type automobile silencing exhaust pipe structure is simple, reasonable in design, waste gas enters interior webmaster 2 inner chamber through the first interpolation pipe 6, air-flow mutually impacts in interior webmaster 2 inner chamber, air-flow velocity is slowed down, by slowly being flowed out by waste gas outlet 5 after the second interpolation pipe 7, to reach the pressure slowing down waste gas; Waste gas noise improves performance muffler after silencing cotton layer 3.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
