Description
Technical field
The present invention relates to building inner water drainage system, belong to inner water drainage system pipe-line equipment technical field in structural material, specifically a kind of UPVC inner helix pipe with hollow wall.
Background technique
UPVC pipeline is take Sanitary PVC (PVC) resin as main raw material, add appropriate stabilizer, oiling agent, bulking agent, toner etc. through plastic extruder extruding and moulding and injection machine molding and forming, by operations such as cooling, curing, sizing, check, packings to complete the production of tubing, pipe fitting; Its physical and chemical performance is good, resistance to chemical attack, and impact strength is high, and fluid resistance is little, improves 30% with bore cast iron tube flow, and ageing-resistant, long service life, is not less than 50 years service life, is the ideal material of building water supply and drainage.In the sewer and various drain pipe in city, the use of various forms tubing is more and more.Existing structured wall popes respectively has its advantage, but also has its deficiency.Some structured wall popes have good ring stiffness and axial pliability, but mostly produce with winding method, and technique is more complicated.The axial dead zone structure of some structured wall popes has improved its axial property, can on the extruding production line of standard, produce, and good manufacturability, but its axial pliability and ring stiffness decline to some extent; The radially dead zone structure of structured wall popes also having has improved its ring stiffness and pliability, but its erosion-resisting characteristics slightly declines, and produces with winding method, and technique is more complicated.
The pipeline of structural material inner water drainage system generally uses cast iron tube or stoneware pipe; But due to its material heaviness, make cast iron tube or stoneware pipe in step inconveniences such as installation, transportations; The easy fragmentation of stoneware pipe and draining noise are very large, affect rest and the work of resident family; Expandable plastic pipe, although be difficult for fragmentation, its soundproof effect is undesirable, and weight is large.Compare with cast-iron pipe, Corrosion Protection is good because having for the water pipe of PVC material, simple installation, quality light, lower-price characteristic, and is widely used.But pvc pipe road soundproof effect is poor, it is during as high-rise waste pipe, because perpendicular distance is long, inner-walls of duct is smooth, when draining, water flow impact pressure is powerful and produce larger noise, affect low layer user's normal rest, the excessive damage that with the passing of time also can cause low layer pipeline of impact force producing in pipeline, affects working life of pipeline.A traditional mode of production UPVC sink drain part is to produce by single wall internal spiral structure, and this structure only considers that current spiral is dirty, has reduced the sound of current, but completely not isolated, pipe intensity will increase, and only has the pipe of increasing wall thickness, and cost has just increased like this; Traditional mode of production UPVC sink drain another part is that hollow-wall drainpipe structure is produced, and this kind of structure not only tube wall strength increases to some extent, and cost reduces to some extent, but its drawback is that soundproof effect is not obvious.
Therefore,, in order further to reduce flowing water noise, some pvc pipe material manufacturing enterprises of China on the basis of UPVC spiral hush pipe, do painstaking research, but the quality of its erasure effect and tubing are not very desirable, can not reach the target of setting.
Summary of the invention
The object of the invention is to, a kind of UPVC inner helix pipe with hollow wall is provided, can prepare a kind of UPVC inner helix pipe with hollow wall material by the method, it is high that this tubing is compared common tube equipment structure intensity, and the comprehensive mechanical performances such as existing good impact resistance, ring stiffness, axial pliability, have again superior technology capability, can on the upper product line of standard, produce, manufacturing efficiency is high, and lightweight, and cost of production is low; And erasure effect is good, can effectively suppress the sound that current flow downward from height.
For achieving the above object, a kind of UPVC inner helix pipe with hollow wall of the present invention, described tubing is cylindric, the tube wall of this tubing comprises inner tubal wall and outer tube wall, between described inside and outside tube wall, is hollow; Described inner tubal wall is helical water guide wall.
Say further, its unsuccessful angle of the helical water guide wall of described inner tubal wall is vertical angle 35～60 °.
Say further, between described inner tubal wall and outer tube wall, be provided with evenly and at intervals some ribs hollow is divided into several vestibules.
Say further, the some ribs that are provided with between described inner tubal wall and outer tube wall are parallel with the helical water guide wall spiral angle of inner tubal wall.
Say further, the top, helical water guide wall cross section of described inner tubal wall is arc transition, and this helical water guide wall around the axis of described tubing in the shape of a spiral.
Say further, the pitch of described helix angle is 800～900mm.
Say further, described helical water guide wall cross section is rib shape projection, and the top of this rib shape projection is arc shaped surface.
A kind of UPVC inner helix pipe with hollow wall of the present invention, its beneficial effect is: the noise that UPVC hollow wall internal spiral silencing pipe of the present invention produces in the time of draining reduces greatly, current fall in the shape of a spiral under the guide functions of helical water guide wall, and on wall under the double action of porous, can greatly reduce the noise of pipe-line system, draining noise power is only 50% of common tube; Current are obvious attached jet, have reduced water velocity, reduce overflow resistance coefficient, keep tubing central gas core up/down perforation, steadily overpressure fluctuates, and has improved the drainability of standpipe, reduced air displacement, drainability increases approximately 25～35%, and air displacement reduces approximately 15～20%; Owing to there being unimpeded air column in pipe, reduce overpressure and pressure surge, improve pipeline and used safety coefficient; Helical water guide wall has remarkable reinforing function, can effectively reduce longitudinal bamboo sample fracture phenomena that pipeline is caused by external impacts; Multiple holes set between inside and outside tube wall not only have sound deadening, have also increased tube wall strength, have reduced the cost of production of tubing, are environment-friendly and energy-efficient product of new generation.
