Abstract
The utility model relates to a foaming involute quiet pipe. The surface of the inner wall of the pipe is uniformly distributed with a plurality of spiral line prominences; both the wall of the pipe and the spiral line prominences are foaming products; the longitudinal extending length of the spiral line prominences penetrates the length of the pipe; the utility model can cause water flow to orderly shed in a vortex shape along the spiral line prominences through a plurality of spiral line prominences on the inner wall of the pipe, and a water hammer effect is reduced; when draining sounds contact the foaming wall of the pipe, a sound transmission effect is reduced to achieve the goal of noise reduction. The utility model has the advantages of unique structure, low cost, high strength, high rigidity, less noise, long service life, etc.
Description
The utility model belongs to drainage pipe, specifically is a kind of foaming inward turning low noise tubing.
In the prior art, the plastic drain pipe of indoor use, because factors such as wall thickness, material behaviors, in drainage procedure, the noise that its draining forms under water hammer effect surpasses the NBS requirement, and environment is affected.
The purpose of this utility model solves above existing in prior technology problem with regard to being, provides a kind of structure uniqueness, cost is low, noise is little, intensity is high, the novel drainage pipe of good rigidly and long service life.
The purpose of this utility model realizes by following measure.Foaming inward turning low noise tubing, the inner wall surface of this tubing is evenly distributed with some Luo Xuan line style convex partss, and tube wall and Luo Xuan line style convex parts are foaming body, and the longitudinal extension length of Luo Xuan line style convex parts is through the length of tubing.This tubing is made with herd polyvinyl chloride material.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model sectional drawing;
Fig. 2 is the longitudinal sectional drawing of Fig. 1;
Fig. 3 is another embodiment's of the utility model a sectional drawing.
As shown in Figure 1 and Figure 2, the utility model foaming inward turning low noise tubing is made with herd polyvinyl chloride material.Inwall 4 surfaces of this tubing are evenly distributed with some Luo Xuan line style convex partss 2, tube wall 1 and Luo Xuan line style convex parts 2 are foaming body 3, the cross section of Luo Xuan line style convex parts 2 can be semicircle, triangle or other arbitrary shape, and the longitudinal extension length of Luo Xuan line style convex parts 2 is through the length of tubing.
Fig. 3 is another embodiment's of the utility model a sectional drawing.Tube wall 1 is sclerine with inwall 4, and there are equally distributed some Luo Xuan line style convex partss 2 on the surface of inwall 4, accompanies foaming body 3 between tube wall 1 and the inwall 4, further reaches erasure effect simultaneously with the inward turning structure.
The utility model is mainly by equally distributed some the Luo Xuan line style convex partss 2 in pipe material inner wall 4 surfaces, making current be the eddy current form along Luo Xuan line style convex parts 2 rushes down down in order, reduce water hammer effect, when its draining sound touches the foaming pipe wall body simultaneously transaudient effect is weakened, thereby reach the purpose that reduces noise.
Compared with prior art, the utlity model has the structure uniqueness, cost is low, intensity is high, good rigidly, The advantages such as the little and long service life of noise reduce by 1.2～2 decibels of noises than traditional cast iron tubing, mould than sclerine Material tubing reduces by 9～10 decibels of noises, be a kind of practical, be applicable to the novel tube that indoor drainage is used. Use it, will bring a more quietly living environment for resident family.
