Abstract
The invention provides a silencer which comprises a body, an air inlet pipe and an air outlet pipe. A portion of the air inlet pipe entering the body is forked into a branch pipe I and a branch pipe II, holes are formed in the branch pipe I and the branch pipe II, a pressure sensor is arranged at one hole of the branch pipe I, a pressure release valve is arranged at a pipe inlet end of the branch pipe II, the other end of the branch pipe II is connected with a buffer chamber, an exhaust port leading to a silencing device is formed in the buffer chamber, and a filtering device is arranged between the silencing device and one side of the body provided with the air outlet pipe. The silencer has the advantages that the silencer is simple and reasonable in structure, fine in silencing effect and convenient to popularize, silencing requirements of tail gas under different running conditions can be met by the aid of a branch structure and the pressure release valve, and the filtering device is a nickel screen, so that impurities such as dust in tail gas can be effectively filtered.
Description
Technical field
The present invention relates to automobile exhaust system, be specifically related to a kind of connection blow-down silencer.
Background technique
Along with expanding economy, people more and more pursue a kind of mode of transportation of convenient environmental protection again, such as automobile.In recent years, due to popularizing rapidly of automobile, the environmental problem brought is also urgently to be resolved hurrily.Wherein, automobile exhaust pipe is one of source discharging the much noise produced in tail gas process, and the baffler of automobile can reduce these noises.Traditional baffler erasure effect when tail gas is normally arranged logical is good, but road surface and all factors such as artificial make automobile to advance with constant speed always, particularly run into uphill way or road surface unobstructed travel rapidly situation time, the baffler efficiency connecting exhaust pipe end is very low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of baffler that can adapt to different travel situations, good muffling effect.
For solving this technical problem, the technical solution used in the present invention is:
A kind of baffler, comprise body, suction tude and steam outlet pipe, it is arm I and arm II that suction tude enters body part bifurcated, arm I and arm II all have hole, and arm I hole is provided with pressure transducer, the pipe end that enters of arm II is provided with Decompression valves, and the other end of this arm II connects buffer cavity, buffer cavity has the relief opening leading to silencer, between silencer and the body side being provided with steam outlet pipe, be provided with filtrating equipment.
Further, arm I is thicker than arm II, and the hole I that arm I has is larger than the hole II that arm II has.
Further, body inwall scribbles noise reduction layer.
Further, acoustical panel or silencing cotton is also provided with in buffer cavity.
Further, filtrating equipment is nickel screen.
Advantage of the present invention is: this muffler structure is simple, reasonable; Use branched structure and Decompression valves, can adapt to the noise reduction requirement of tail gas under different travel situations, good muffling effect, is convenient to promote; Nickel screen selected by filtrating equipment, can the impurity such as dust effectively in filtering tail gas.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein, 1, body, 2, suction tude, 201, arm I, 202, arm II, 3, steam outlet pipe, 4, hole I, 401, hole II, 5, silencer, 6, filtrating equipment, 7, Decompression valves, 8, pressure transducer, 9, buffer cavity, 10, relief opening.
Embodiment:
As shown in Figure 1: a kind of baffler, comprise body 1, suction tude 2 and steam outlet pipe 3, it is arm I 201 and arm II 202 that suction tude 1 enters body part bifurcated, arm I 201 and arm II 202 all have hole, and arm I 201 hole is provided with pressure transducer 8, the pipe end that enters of arm II 202 is provided with Decompression valves 7, the other end of this arm II 202 connects buffer cavity 9, buffer cavity 9 has the relief opening 10 leading to silencer 5, between this silencer 5 and body 1 side being provided with steam outlet pipe 3, be provided with filtrating equipment 6.
Further, arm I 201 is thicker than arm II 202, and the hole I 4 that arm I 201 has is larger than the hole II 401 that arm II 202 has.
Further, body 1 inwall scribbles noise reduction layer.
Further, acoustical panel or silencing cotton is also provided with in buffer cavity 9.
Further, filtrating equipment 6 is nickel screen.
In automobile normal running process, tail gas enters branched structure through suction tude 2, most tail gas passes in arm I 201, and entered in silencer 5 by the hole I 4 on it and abate the noise, all the other enter in arm II 202 carries out part noise reduction process, and last two pipe tail gas after filtration device 6 filter rear discharge; When automobile accelerates to a certain degree, the high pressure that pressure transducer 8 senses makes Decompression valves 7 open, increase the air displacement of arm II 202, these tail gas increased enter in the buffer cavity 9 of arm II 202 end, enter in silencer 6 after acoustical panel wherein or the further noise reduction of silencing cotton are set filter, the tail gas of discharging with arm I 201 together through impurity such as nickel screen 6 filtering dusts, is discharged finally by steam outlet pipe 3.
