Abstract
The utility model discloses an anechoic sewer pipe which is with anechoic structure and consists of double-layer pipe wall and filling material. Wherein,the filling material which is made from heat conservation and sound proof material of light quality is filled in the double-layer pipe wall with simple structure, and low cost; the double-layer pipe wall has the function of sound proof, the filling material has the function of sound absorption, so the effects of sound elimination and noise decrease of the anechoic structure are more thorough.
Description
Technical field the utility model relates to a kind of building sewer pipe, especially has the building sewer pipe of noise elimination structure.
Background technology is present, and no matter be the sewer pipe of iron pipe, pvc pipe, pipe of cement or other material, more or less all there is noise in the sewer pipe of many buildings.
Chinese patent CN2499671 number disclosed " multilayer silencing connection pipe fitting " patent (application number: CN01250506.4), comprise threeway and elbow, its tube wall is to be made of multilayer, between the adjacent two layers wall certain clearance is arranged, the connecting tube sound absorption good muffling effect of this new structure, can be extensively as all kinds of highrise buildings, the connecting tube of sewer pipes such as washroom, kitchen.The weak point of this patent is: only be the connecting tube noise reduction at the building sewer pipe, erasure effect is poor, because sound still can be propagated in other position.
In addition, there be not to find the documents relevant with duct attenuation.
The summary of the invention the purpose of this utility model is exactly for a kind of noise elimination sewer pipe simple in structure being provided, making that its noise elimination noise reduction effect is better.
In order to achieve the above object, the noise elimination sewer pipe that the utility model provides has noise elimination structure: noise elimination structure is made up of double-layer tube wall and packing material, and wherein, packing material is made by the light-weight thermal-insulating and sound-insulating material, is filled between the double-layer tube wall.
The noise elimination sewer pipe that the utility model provides has positive effect: noise elimination structure is made up of double-layer tube wall and packing material, and is simple in structure, and cost is low; Double-layer tube wall has deadening, and packing material has sound absorption, thereby the noise elimination noise reduction effect of noise elimination structure is more thorough.
Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing. expression the utility model structural representation.
Structure shown in the drawings comprises: double-layer tube wall (1), packing material (2).
The noise elimination sewer pipe that specific embodiment the utility model provides has noise elimination structure: noise elimination structure is made up of double-layer tube wall (1) and packing material (2), and wherein, packing material (2) is made by the light-weight thermal-insulating and sound-insulating material, is filled between the double-layer tube wall (1).
The utility model protection domain relates to all changes form recited above.
