Abstract
The utility model relates to the sound-absorbing field, in particular to a corrosion-resistant sound-absorbing exhaust pipe which comprises a sound-absorbing exhaust pipe main body. The sound-absorbing exhaust pipe main body comprises a stainless steel fixing sleeve, basalt fiber cloth, a perforated ceramic pipe A, perforated basalt fiber cloth and a perforated ceramic pipe B, wherein the sound-absorbing exhaust pipe main body is sequentially provided with the stainless steel fixing sleeve, the basalt fiber cloth, the perforated ceramic pipe A, the perforated basalt fiber cloth and the perforated ceramic pipe B from the outside in, is made of a nonmetallic material, and can neither be corroded by sulfides and phosphides nor get rusty; and as the basalt fiber material can play roles of both sound absorption and sound attenuation, the porous pipe can reduce automobile noise more effectively.
Description
Technical field
The utility model relates to the noise reduction field, is specifically related to a kind of corrosion-resistant noise reduction outlet pipe.
Background technique
Along with the develop rapidly of China's economic construction, the Motor Vehicle sales volume increases sharply in China, but existing problem also excellent opinion highlight.Motor Vehicle uses 1 year outlet pipe sound just to become unusual big, this mainly is because contain sulphide and phosphide in the tail gas that automobile is discharged, these materials remain in the automobile exhaust pipe, and chemical corrosion and electrochemical corrosion can take place, the outlet pipe outside still is brand-new, but inner noise reduction metal device is by heavy corrosion, and outlet pipe does not have the effect of noise reduction yet; Nowadays most of car owners are natural gas facility with automobile repacking, this method is economy environmental protection again, but car owners and not knowing not only can discharge sulphide and phosphide behind the combustion of natural gas, also have water generates, accelerated the service life of mobile muffler so again.
The model utility content
The purpose of this utility model is at the defective of prior art and deficiency, provide a kind of simple in structure, a kind of corrosion-resistant noise reduction outlet pipe reasonable in design, easy to use, it adopts nonmetallic material to make, the corrosion of thing and phosphide can not cure, more can not get rusty, and the basalt fiber material self that adopts just has sound-absorbing, sound deadening, the pipeline of porous more can significantly reduce car noise.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of corrosion-resistant noise reduction outlet pipe described in the utility model, comprise noise reduction outlet pipe body, described noise reduction outlet pipe body comprises stainless steel fixed cover, basalt fiber cloth, stoneware pipe A with holes, basalt fiber cloth with holes and stoneware pipe B with holes, and described noise reduction outlet pipe body ecto-entad is disposed with stainless steel fixed cover, basalt fiber cloth, stoneware pipe A with holes, basalt fiber cloth with holes and stoneware pipe B with holes.
Further, described stoneware pipe A with holes surface is provided with some aperture A.
Further, described stoneware pipe B with holes surface is provided with some aperture B.
After adopting said structure, the utility model beneficial effect is: the utility model it adopt nonmetallic material to make, the corrosion of thing and phosphide can not cure, more can not get rusty, and the basalt fiber material self that adopts just has sound-absorbing, sound deadening, and the pipeline of porous more can significantly reduce car noise.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 sectional drawing.
Description of reference numerals:
1, stainless steel fixed cover; 2, basalt fiber cloth; 3, stoneware pipe A with holes; 4, basalt fiber cloth with holes; 5, stoneware pipe B with holes.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of corrosion-resistant noise reduction outlet pipe described in the utility model, comprise noise reduction outlet pipe body, described noise reduction outlet pipe body comprises stainless steel fixed cover 1, basalt fiber cloth 2, stoneware pipe A3 with holes, basalt fiber cloth with holes 4 and stoneware pipe B5 with holes, and described noise reduction outlet pipe body ecto-entad is disposed with stainless steel fixed cover 1, basalt fiber cloth 2, stoneware pipe A3 with holes, basalt fiber cloth with holes 4 and stoneware pipe B5 with holes.
Further, described stoneware pipe A3 with holes surface is provided with some aperture A.
Further, described stoneware pipe B5 with holes surface is provided with some aperture B.
The utility model is fixed on the basalt material of sound absorption in the earthenware duct of air-flow path, has just constituted dissipative muffler.When sound wave entered dissipative muffler, a part of acoustic energy fell changing into thermal dissipation through friction among stoneware pipe A3 with holes, basalt fiber cloth with holes 4 and the stoneware pipe B5 with holes, and the sound wave by silencing apparatus is weakened.Basalt fiber cloth 2 is for through basalt fiber cloth after the special processing, and main effect is to prevent sulphide in the vehicle exhaust and phosphide product in baffler, corrosion stainless steel protection pipe.
The utility model its adopt nonmetallic material to make, and thing and the phosphide corrosion that can not cure more can not got rusty, and the basalt fiber material self that adopts just has sound-absorbing, sound deadening, and the pipeline of porous more can significantly reduce car noise.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
