Abstract
The utility model discloses a silence down-corner which comprises an external pipe and a soft internal pipe, wherein the soft internal pipe is internally provided with helical vanes; a soundproof felt is arranged between the external pipe and the soft internal pipe; the helical vanes are arranged in the soft internal pipe; the turbulence of the water in the down-corner is increased, the water is prevented to flow downwards vertically from the down-corner mouth, therefore, the impact force of the water on the soft internal pipe wall and the noise are reduced; furthermore, the soundproof felt is arranged between the external pipe and the soft internal pipe, thus further eliminating the noise. The silence down-corner is simple in structure and the problem that the noise generated during the use process of the existing down-corner disturbs the residents can be solved effectively.
Description
Technical field
The utility model relates to a kind of building pipe, relates in particular to a kind of noiseless sewer.
Background technique
At present, all there is noise problem in plastics sewer for building, i.e. the noise that produces owing to the interior pipe of water slug sewer, and the noise of sewer has had a strong impact on resident's normal rest, especially lives in the army and the people of bottom.In order to address this problem, people have invented a kind of soft inner wall tube that installs on the inwall of outer wall pipe.Though soft inner wall tube has been alleviated the impact force of water to inner tubal wall, thereby played the effect of damping, noise reduction, but can not thoroughly abate the noise.
The model utility content
The purpose of this utility model just is to provide a kind of noiseless sewer, has solved the problem that existing sewer noise disturbs residents.
In order to solve the problems of the technologies described above, the technical solution of the utility model is such: a kind of noiseless sewer, comprise outer tube and soft interior pipe, and in the described soft interior pipe helical blade is installed, be provided with deadening felt between described outer tube and the soft interior pipe.
Compared with prior art, advantage of the present utility model is: helical blade is installed in the pipe in soft, has been increased the turbulivity of water in the sewer, avoided water to flow vertically downward from the sewer mouth, thereby reduced the impact force of water, reduced noise soft inner tubal wall; Secondly outer tube and soft in deadening felt is set between the pipe, can further abate the noise, the utility model is simple in structure, has effectively solved the problem that noise disturbs residents in the existing sewer using process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
