Description
Technical field
This utility model belongs to automotive silencing apparatus technical field, is specifically related to a kind of porous bypass type muffler.
Background technology
In long-term working practice, being provided with hush tube and be set to two in general-utility car acoustic filter, tail gas vibrations are being eliminated the noise
The abatement time period is consumed in device noise is limited is unable to reach standard, disappears although being provided with three hush tubes in another kind of acoustic filter
Sound increases, but due to air inlet pipe with exhaustor is close together or staggered relatively makes the 3rd hush tube sound deadening little
It is unable to reach national standard.
Summary of the invention
The purpose of this utility model is: the distance between air inlet pipe and exhaustor can be strengthened, make noise vibration disappear
Disappear completely in sound device and be minimized, and the 3rd hush tube is placed between air inlet pipe and exhaustor, the 3rd can be made
Hush tube noise elimination effect performs to maximum can reach country's noise reduction standard, and its technical scheme is as follows:
A kind of porous bypass type muffler, it include shell body 1, fixing end cap 2, stationary barrier 3, air inlet core pipe 4,
Intermediate core pipe 5, exhaust core pipe 6, trocar sheath 7, glass fibre 8, it is characterised in that: described shell body about 1 top end surface is each solid
Determining connection has fixing end cap 2, described shell body 1 private side top end surface to be evenly distributed and be fixedly connected with several stationary barriers 3,
The left side described fixing end cap 2 air inlet core pipe 4 that is fitted with fixed above, is fixedly connected with centre at described shell body 1 bosom
Core pipe 5, fixes below the described fixing end cap 2 in right side and is fitted with exhaust core pipe 6, described exhaust core pipe 6 side top end surface right edge
Fix at edge and be fitted with trocar sheath 7, between described exhaust core pipe 6 and described trocar sheath 7, fix being fitted with glass fibre 8, described
Shell body 1 is internal is fixedly connected with two described stationary barriers 3, and described air inlet core pipe 4, described intermediate core pipe 5 and described row
Gaseous core pipe 6 is fixing is inserted into described stationary barrier 3 side surface, is provided with several rows on the right side of the top end surface of described air inlet core pipe 4 side
Pore, top end surface middle, described intermediate core pipe 5 side is provided with several steam vents, in the top end surface of described exhaust core pipe 6 side
Between place and right edge be respectively provided with several steam vents, in reducing type shape at the top end surface right side edge of described air inlet core pipe 4 side
Shape, in flared shape at the top end surface right side edge of described intermediate core pipe 5 side, described air inlet core pipe 4, described intermediate core pipe 5
With described exhaust core pipe 6 in parallel placement.
The beneficial effects of the utility model are: the distance between air inlet pipe and exhaustor can be strengthened, make noise vibration
Disappear completely in acoustic filter and be minimized, and the 3rd hush tube is placed between air inlet pipe and exhaustor, can be made
Three hush tube noise elimination effects perform to maximum and can reach country's noise reduction standard.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention:
With reference to porous bypass type muffler a kind of described in Fig. 1, it includes shell body 1, fixing end cap 2, stationary barrier
3, air inlet core pipe 4, intermediate core pipe 5, exhaust core pipe 6, trocar sheath 7, glass fibre 8, it is characterised in that: described shell body about 1
Top end surface is respectively fixedly connected with fixing end cap 2, described shell body 1 private side top end surface be evenly distributed be fixedly connected with some
Individual stationary barrier 3, the described fixing end cap 2 in the left side air inlet core pipe 4 that is fitted with fixed above, solid at described shell body 1 bosom
Determine connection and have intermediate core pipe 5, the fixing exhaust core pipe 6 that is fitted with, top, described exhaust core pipe 6 side below the described fixing end cap 2 in right side
Fix at end surfaces right side edge and be fitted with trocar sheath 7, between described exhaust core pipe 6 and described trocar sheath 7, fix being fitted with glass
Glass fiber 8, described shell body 1 is internal is fixedly connected with two described stationary barriers 3, and described air inlet core pipe 4, described intermediate core
Pipe 5 and described exhaust core pipe 6 are fixed and are inserted into described stationary barrier 3 side surface, set on the right side of the top end surface of described air inlet core pipe 4 side
Several steam vents, top end surface middle, described intermediate core pipe 5 side is had to be provided with several steam vents, described exhaust core pipe 6 side
Top end surface middle and right edge are respectively provided with several steam vents, at the top end surface right side edge of described air inlet core pipe 4 side
In reducing type shape, in flared shape at the top end surface right side edge of described intermediate core pipe 5 side, described air inlet core pipe 4, described
Intermediate core pipe 5 and described exhaust core pipe 6 are in parallel placement.
During use, first gas enters between shell body 1 and the fixing end cap 2 at two ends internal from air inlet core pipe 4, gas from
Steam vent on right section of air inlet core pipe 4 and side surface gets rid of gas, room in the second of stationary barrier 3 formation of gas entrance simultaneously
