The HDPE composite inner spiral sound attenuation pipe is simple in structure and reasonable in design, water flow is forced to rotate and flow down along the inner wall of the sound attenuation pipe under the diversion of the spiral convex ribs when water is drained, collision between water flow and air is reduced, the longitudinal fracture phenomenon caused by water flow impact on the sound attenuation pipe can be effectively reduced, and noise of water flow is reduced. Meanwhile, the inner wall of the sound attenuation pipe is not prone to scaling, water flow is smooth, the sound attenuation pipe is not prone to being blocked, the HDPE composite inner spiral sound attenuation pipe is made of HDPE or mineral filled HDPE, and after the sound attenuation pipe is filled with minerals, the sound attenuation effect is further enhanced.
Description
Technical field
The utility model belongs to drainage pipe technical field, is specifically related to the compound internal spiral silencing pipe of a kind of HDPE simple in structure, corrosion-resistant, that noise reduction is forged a good relationship.
Background technique
Now widely used construction drainage pipeline mainly contains PVC-U pipe, cast iron tube and HDPE pipe.PVC-U pipeline pressure-bearing and resistance to heat a little less than, and noise is large, when burning, can produce poison gas; Cast-iron pipe is perishable, installation is difficult.Compare with cast-iron pipe, the feature such as Corrosion Protection is good because having for the water pipe of HDPE material, simple installation, quality are light, is widely used in office building, apartment, hospital, villa, school etc.But in actual application, there is the poor defect of erasure effect in traditional HDPE tubing, HDPE tubing, PVC helical silencing tubing, need to modify to its structure.
Model utility content
The problem existing for prior art, the purpose of this utility model is that design provides the compound internal spiral silencing pipe of a kind of HDPE simple in structure, corrosion-resistant, that noise reduction is forged a good relationship.
The compound internal spiral silencing pipe of described a kind of HDPE, comprise hush pipe body, described hush pipe body is the double layer construction being made up of inner tube and outer tube, it is characterized in that between described inner tube and outer tube, interval arranges one group for being connected the supporting rib of inner tube and outer tube, supporting rib length is identical with the length of inner tube and outer tube, on described inner pipe wall, evenly arrange one group by the spiral convex rib of counterclockwise spiral, described spiral convex rib cross section is triangular structure, it is highly 3-4mm, the compound internal spiral silencing pipe of this HDPE adopts high density polyethylene (HDPE) or mineral-filled high density polyethylene (HDPE) to make, adopt mineral-filled after, erasure effect can be further strengthened.
The compound internal spiral silencing pipe of described a kind of HDPE, is characterized in that described supporting rib quantity is 12-24 bar, and supporting rib is parallel with hush pipe body center line.
The compound internal spiral silencing pipe of described a kind of HDPE, is characterized in that described spiral convex rib quantity is 6-12 bar, and the angle of spiral convex rib and hush pipe body center line is 30 °.
The compound internal spiral silencing pipe of described a kind of HDPE, is characterized in that the height of described supporting rib equals the spacing between inner tube and outer tube structure, and supporting rib height is 2-3mm.
The compound internal spiral silencing pipe of described a kind of HDPE, is characterized in that described hush pipe body outer tube diameter is 75-160mm, and its inner tube and outer tube wall thickness are respectively 3.5-7mm.
By adopting above-mentioned technology, the compound internal spiral silencing pipe of HDPE obtaining, it is simple in structure, reasonable in design, compared with prior art has following beneficial effect:
1) the utility model by being provided with spiral convex rib on hush pipe body inner pipe wall, spiral convex rib is under counterclockwise screw and distributes, under the water conservancy diversion of the spiral convex rib that when draining, current are 3-4mm at 6-12 root height, force current to flow down along inner-walls of duct counter-rotating, reduce the collision of itself and air, can effectively reduce the longitudinal break phenomenon that pipeline is caused by water impact, reduce the noise of current, and its spiral convex rib direction is eddy flow counter clockwise direction, inboard wall of tube body can produce diversion column, thereby inboard wall of tube body is difficult for sticking foul, current are unimpeded, be difficult for blocking,
2) hush pipe body of the present utility model is set to the double layer construction being made up of inner tube and outer tube, inner tube adopts supporting rib to be connected with outer tube, in the middle of inside and outside tube wall, have space, the noise and vibration of inner pipe wall can not passed to outer tube wall, thereby reduces the noise producing of outer tube wall;
3) material of hush pipe body of the present utility model adopts high density polyethylene (HDPE) (HDPE) or mineral-filled high density polyethylene (HDPE) to make, compared with PVC isostructure volute, flowing water noise reduces 5-10 decibel, and pliability is good, the curved performance of tension is excellent, when burning, can not produce toxic substance yet, to environment without harm.
