Abstract
The utility model relates to a kind of mufflers, and in particular to the muffler for carrying out out to the noise of gas discharge.Including air inlet, gas outlet, shell and enclosure interior pipeline, the pipeline is double-spiral structure, the air inlet is a cavity, two holes of the double-stranded pipeline of connection, the gas outlet is a cavity, two holes of the other end of the double-stranded pipeline of connection, are provided with thermal insulation layer between inner housing and outer housing, the pipeline gap is filled with damping layer.Pipeline uses double-spiral structure, in the cavity of air inlet, sound wave and gas are divided into two by double helix pipeline, there are length differences for double helix pipeline overall length, mixed interference is carried out in the cavity of gas outlet, sound wave is more preferable by interference effect and the mutual attenuation inside double helix pipeline, the effect of noise reduction.
Description
Technical field
The utility model relates to a kind of mufflers, and in particular to the exhaust noise silencing for carrying out out to the noise of gas discharge
Device.
Background technique
Exhaust silencer is the important component for reducing exhaust noise, it by reduce, decay pressure at expulsion pulse come
Noise is eliminated, a superior muffler of performance, it can effective attenuation exhaust noise.Existing muffler only with every
Plate or filter screen carry out the buffering to gas, and effect is not obvious.
Utility model content
The utility model provides a kind of muffler, including air inlet 1, gas outlet 2, shell 3 and enclosure interior pipe
Road 4, it is characterised in that: the pipeline is double-spiral structure, and the air inlet is a cavity, the double-stranded pipeline of connection
Two holes, the gas outlet be a cavity, two holes of the other end of the double-stranded pipeline of connection.
Further, the shell is made of left shell and right shell body, and connection is respectively arranged on left shell and right shell body
Ear, and be bolted.
Further, filter screen is provided in the cavity of the air inlet, the filter screen is placed in cavity, institute
It states filter screen to be made of the bracing ring of intermediate filter layer and periphery, is provided with a circle boss 5, the support on the inside of the cavity
It encloses on the circle boss being stuck on cavity wall.
Further, multilayer can be set in the filter screen, and the substance that every layer of filter screen is filtered has specific aim.
Further, spacer ring is provided between the multiple filtration net.
Further, the shell includes inner housing and outer housing, be provided between the inner housing and outer housing every
Thermosphere.
Further, the material of the pipeline is sound absorption heat proof material.
Further, the pipeline gap is filled with damping layer.
The beneficial effects of the utility model are:
(1) pipeline uses double-spiral structure, and in the cavity of air inlet, sound wave and gas are divided into two and pass through double spiral tube
Road, double helix pipeline overall length carry out mixed interference there are length difference in the cavity of gas outlet, sound wave by interference effect and
Mutual attenuation inside double helix pipeline, the effect of noise reduction are more preferable.
(2) setting of multiple filtration net filters out the impurity and pernicious gas in gas by layering；
(3) shell uses Design on thermal insulation, and external touch-safe improves.
(4) pipeline gap is filled with damping layer, reduces the vibration of pipeline, is also enhanced while reaching damping effect
Noise elimination effect.

Road is double-spiral structure, and the air inlet is a cavity, and two holes of the double-stranded pipeline of connection, the gas outlet is
One cavity, two holes of the other end of the double-stranded pipeline of connection.
Filter screen is provided in the cavity of the air inlet, the filter screen is placed in cavity, the filter screen
It is made of the bracing ring of intermediate filter layer and periphery, is provided with a circle boss on the inside of the cavity, the bracing ring is stuck in sky
On a circle boss in cavity wall.
Multilayer can be set in the filter screen, and the substance that every layer of filter screen is filtered has specific aim.
Embodiment 5:
Roughly the same with embodiment 4, difference is, the material of the pipeline is sound absorption heat proof material, the pipeline gap
It is filled with damping layer.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvement and supplement without departing from the principle of this utility model, these are improved and supplement
Also it should be regarded as the protection scope of the utility model.
