Abstract
The utility model relates to a sewer pipe with an inner helical corrugation. At least one helical corrugation is distributed on the inner wall of a column sheath plastic tube 1; the separation angle between the helical corrugation 2 and a column axial lead 3 is 5DEG.-30DEG. The height of the helical corrugation 2 is 1-5 mm. The utility model is suitable for various sewer pipelines of buildings. When a large amount of sewage flow downwards along the inner wall, the downward water is caused to generate helical flow under the action of the helical corrugation, and noise generated by direct current is reduced. Furthermore, a plastic pipe has the advantages of light body, low cost, and corrosion resistance.
Description
The sewer pipe of band inside spin rib belongs to the building annex.
The sewer pipe of existing building generally all is a cast iron quality, and its inside pipe wall is a light, when large amount of sewage is once toppled in the building upper strata in sewer pipe, people in its lower floor just can hear that this noise of noise, especially the dead of night that sewage vertically dashes down can cause scaring and interference to the occupants of lower floor.
The purpose of this utility model is the sewer pipe of a kind of plastic material of development, has scroll on the inwall of this sewer pipe, and sewage can produce eddy flow along the scroll of inwall when dirty in from then on managing, reduce to the greatest extent vertical down towards the time noise that produces.
The utility model is the cylindrical sleeve plastic pipe, is furnished with at least one scroll on the inwall of pipe, and the angle of scroll and cylinder axial line is 5 °-30 °, and the height of rib is 1-5mm.
The utility model can be used for the downcomer line of various buildings and since its inwall on be furnished with many scrolls, when large amount of sewage along under the inwall towards the time, will make the water generates eddy flow, reduce the noise that flings generation, make the user reduce scaring, the reduction noise is compared with cast iron straight pipe and can be reduced by 50%.Its plastic material has the advantage that body is light, corrosion-resistant, cost is low again, can reduce by 50% with cast iron straight pipe than cost.And safeguard also more convenient.
Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment; Present embodiment is a cylindrical sleeve plastic pipe 1, is furnished with six scrolls 2 on the inwall of pipe 1, and scroll 2 is 15 ° with the angle of cylinder axial line 3, and the height of rib 2 is 2mm.
Claims (3)
1, the sewer pipe of band inside spin rib, it is cylindrical sleeve plastic pipe (1), it is characterized in that being furnished with at least one scroll (2) on the inwall of cylindrical sleeve plastic pipe (1).
2, the sewer pipe of band inside spin rib according to claim 1 is characterized in that the scroll (2) and the angle of cylinder axial line (3) are 5 °-30 °.
