Abstract
The utility model relates to a novel noise reduction drain pipe which comprises a soft inner layer, a rigid middle layer and an outer layer which are sequentially arranged from inside to outside, wherein the thickness of the soft inner layer is 0.1-2.0mm, the thickness of the rigid middle layer is 2.0-8.0mm, and the thickness of the outer layer is 0.2-2.0mm. The novel noise reduction drain pipe can reduce vibration caused by draining through the soft inner layer, and accordingly has the sound absorption effect; and further reduces noise due to the fact that the rigid middle layer can prevent vibration.
Description
Technical field
The utility model relates to a kind of pipeline, is specifically related to a kind of noise-reducing drain pipe, belongs to the pipe technology field.
Background technology
The decibel value of the common plastics tube of prior art when draining be generally greater than 54 decibels, and people's normal study, life and sleep produced serious influence.And the general drainage noise of cast iron tubing is about the 45-50 decibel, but cast iron tubing is because perishable and heavy, is unfavorable for installing being eliminated.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved Novel noise reduction gutter that has, to overcome described defective of the prior art.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of Novel noise reduction gutter that can effectively reduce drainage noise.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of Novel noise reduction gutter, and it comprises soft internal layer, rigidity intermediate layer and skin that from-inner-to-outer sets gradually; Wherein, the thickness of described soft internal layer is 0.1-2.0 mm; The thickness in described rigidity intermediate layer is 2.0-8.0 mm; Described outer field thickness is 0.2-2.0 mm.
Novel noise reduction gutter of the present utility model further is set to: the density of described soft internal layer is 1.2-1.6; The density in described rigidity intermediate layer is 1.6-2.0; Described outer field density is 1.45-1.7.
Novel noise reduction gutter of the present utility model also is set to: described soft internal layer, rigidity intermediate layer and outer soft internal layer, rigidity intermediate layer and the skin that is respectively the PVC material.
Compared with prior art, the utlity model has following beneficial effect: Novel noise reduction gutter of the present utility model is by arranging soft internal layer, thereby can reduce the vibration that draining produces, and plays the effect of sound-absorbing; And middle rigidity intermediate layer can stop vibration, with further reduction noise.
Description of drawings
Fig. 1 is the profile of noise-reducing drain pipe of the present utility model.
The specific embodiment
See also shown in the Figure of description 1, the utility model is a kind of Novel noise reduction gutter, and a few part integrated injection moldings such as its soft internal layer 1 that is set gradually by from-inner-to-outer, rigidity intermediate layer 2 and skin 3 form.
Wherein, described soft internal layer 1, rigidity intermediate layer 2 and outer 3 are respectively soft internal layer 1, the rigidity intermediate layer 2 and outer 3 of PVC material.The thickness of described soft internal layer 1 is 0.1-2.0 mm, and density is 1.2-1.6; The thickness in described rigidity intermediate layer 2 is 2.0-8.0 mm, and density is 1.6-2.0; Described outer 3 thickness is 0.2-2.0 mm, and density is 1.45-1.7.Because the density of soft internal layer 1, rigidity intermediate layer 2 and outer 3 is different, thereby form the noise-reducing drain pipe with hierarchical structure.
The design principle of noise-reducing drain pipe of the present utility model is as follows: soft internal layer 1 material that contacts with water is softer, can reduce vibration, plays the effect of a sound-absorbing; Rigidity intermediate layer 2 density are larger, and rigid can stop vibration; Outer 3 density are low effectively to absorb vibration again.Simultaneously, this gutter integral thickness is larger, also can effectively absorb vibration and reduce noise.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
