Abstract
The utility model relates to a silencing tube material, comprising an outer wall tube. The utility model is characterized in that an inner wall tube is arranged in the outer wall tube; the inner wall of the inner wall tube forms a spiral shape; foamed plastic is arranged between the inner wall tube and the outer wall tube. The utility model reserves the advantage of light weight of a PVC tube in the prior art; during water drainage, the centers of the tubes form gas columns to cause water flows to descend spirally along the inner walls of the tubes; the acoustic insulation function of the foamed plastic between the tubes is added; so, the noise of the utility model is greatly decreased, and simultaneously congestion can be reduced to guarantee fluency; in addition, the utility model has the advantages of good corrosion resistant performance, flame resistant performance and insulating performance and high compressive strength.
Description
The utility model relates to a kind of structural material, especially a kind of Silencing tube material that is used for the building discharge pipe line.
The tubing of building discharge pipe line use now generally is the PVC single-walled pipe, and it is that drainage procedure produces bigger noise that this pipe is used for one of shortcoming of discharge pipe line.
The purpose of this utility model provides a kind of novel drainage pipe, just can overcome existing shortcoming in the prior art, can reduce the noise in the draining.
The purpose of this utility model is achieved in that it comprises the outer wall pipe, it is characterized in that offering inner wall tube in the outer wall pipe, and the inwall of inner wall tube is a helical, for further reaching the effect of noise reduction, can also between inside and outside wall pipe expandable plastic be housed.
Inside and outside wall of the present utility model adopts the pvc pipe material, it has kept the light advantage of pvc pipe material body in the prior art, simultaneously because inwall is a helical, during draining, pipe central authorities form gas column, draining stream is descended along the inwall curl of pipe, the deadening of expandable plastic in addition, so having significantly, the noise that the utility model produces than other drainage pipe of the prior art descends, can reduce simultaneously to block, smoothness be can guarantee, corrosion-resistant preferably and fire-retardant, insulating property the utlity model has in addition, and higher compressive strength.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is a side sectional view of the present utility model.
Fig. 2 is an end-face structure schematic representation of the present utility model.
1 is the outer wall pipe shown in the figure, the 2nd, and inner wall tube is equipped with expandable plastic 3 in the centre of inner wall tube and outer wall pipe, and as seen from the figure, the inwall of inner wall tube is processed with screw thread, and a number of the pitch of screw thread and screw thread depends on the needs.
Claims (2)
1, Silencing tube material, it comprises the outer wall pipe, it is characterized in that offering inner wall tube in the outer wall pipe, the inwall of inner wall tube is a helical.
2,, it is characterized in that between inside and outside wall pipe, expandable plastic being housed according to the said Silencing tube material of claim 1.
