Abstract
The utility model discloses a kind of PVC drain pipe, comprises body, and described body is the foam layer of basic unit, microvesicle cellular structure from outside to inside; Described basic unit comprises PVC internal layer, steel wire sandwich layer, PVC skin, basic unit's from-inner-to-outer integrated injection molding; Silicon core layer is provided with in described foam layer; Described silicon core layer, foam layer and basic unit are by being glued to one.The utility model structure is simple, be easy to manufacture, have sound insulation function, bearing capacity by force, not easily aging, not easily scratch, long service life, particularly suitable construction drainage engineering uses.
Description
Technical field
The utility model relates to pipeline field, is specifically related to a kind of PVC drain pipe.
Background technique
Along with the continuous progress of new material technology, " to mould Dai Gang " substitute technology has become the development trend of China's water & wastewater engineering for building application material.Water & wastewater engineering for building has used the iron drain-pipe of the heaviness in a nearly century to be eliminated gradually, the substitute is new material PVC drain pipe.The individual layer body that PVC drain pipe pipe adopts pvc material to be formed through extruded method usually, it have lightweight, little, the corrosion resistance of conveying fluid resistance is strong, non-corrosive, installation labor intensity are little, economic benefit very outstanding feature, obtain at home at present and greatly develop and apply.Due to material or the structural limitations of PVC drain pipe, there are some shortcomings in PVC drain pipe: fragility is strong, easily ruptures when installing or use; During floor higher use, noise is comparatively large, affects quality of life; Time in the water of discharge containing corrosive gas, easy fouling and pollution etc.
China's application number is the model utility of 2011204175721, discloses a kind of mute drainage pipe, is made up of internal layer, foamed core, skin, and mute drainage pipe is extremely interior and be respectively outward: internal layer, foamed core, skin; Internal layer, foamed core and skin are by being glued to one; Described foamed core is microvesicle cellular structure.Although this model utility can play good soundproof effect when using, but have the following disadvantages: one, waste pipe sticks to integral by internal layer, foamed core and outer layer glue, pliability is low, fragility is strong, if waste pipe is when installing or being subject to larger rigid impulse in using process, easy bending deflection or fracture; Its two, be dissolved with H in the water of waste pipe discharge containing high bacteria containing rate, high salinity or the water that discharges
2s, CO
2and O
2deng corrosive gas time, easily cause pipeline scale, pollution, thus pipeline undergauge, circulation area diminish, discharge capacity reduces and line clogging, also can damage time serious sexual behavior therefore; In addition, waste pipe outer surface smoother, install or use time very easily scratch, affect attractive in appearance while also destroy using effect.
Model utility content
For the deficiency that prior art exists, the utility model provides that a kind of noise is low, bearing capacity is high, the not easily aging and PVC drain pipe of long service life.
For achieving the above object, the technological scheme that the utility model is taked:
A kind of PVC drain pipe, comprise body, described body is the foam layer of basic unit, microvesicle cellular structure from outside to inside; Described basic unit comprises PVC internal layer, steel wire sandwich layer, PVC skin, basic unit's from-inner-to-outer integrated injection molding; Described foam layer internal surface is provided with silicon core layer; Described silicon core layer, foam layer and basic unit are by being glued to one.
As optimal technical scheme, in order to improve the bearing capacity of waste pipe thus extend working life of waste pipe, described silicon core layer internal surface is provided with several fins.
As optimal technical scheme, in order to avoid waste pipe occurs scratch when installing or use, thus affect attractive in appearance and using effect, described basic unit is coated with wearing layer.
The beneficial effect that the utility model has:
1, basic unit is provided with on wire-core net and silicon core layer and is provided with some fins, reduces the fragility of waste pipe, strengthens the bearing capacity of waste pipe, avoids, by bending deflection during greater impact or fracture, being beneficial to and extending working time.
2, be provided with silicon core layer, make pipeline have superpower lubricating function, avoid discharge of pipes harmful water to make the structure of generation, blocking, pollution, and rinse convenient, more easy to clean, thus pipeline not easily aging, long service life.
3, pipeline external surface arranges wearing layer, scratch when avoiding Pipe installing or use, not only attractive in appearance but also be conducive to using effect.
4, in basic unit, be provided with the foam layer of microvesicle cellular structure, there is certain soundproof effect, be conducive to the quality of life improving people.
5, the structure of pipeline simple, be easy to manufacture.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the sectional view of the utility model cross section.
Drawing reference numeral: 1, basic unit, 1-1, PVC internal layer, 1-2, steel wire sandwich layer, 1-3, PVC are outer, and 2, foam layer, 3, silicon core layer, 3-1, fin, 4, wearing layer.
Embodiment
As shown in Figure 1, a kind of PVC drain pipe, pipe is the foam layer 2 of basic unit 1, microvesicle cellular structure from outside to inside.
Described basic unit comprises PVC internal layer 1-1, the outer 1-3 of steel wire sandwich layer 1-2, PVC, basic unit 1 from-inner-to-outer integrated injection molding; The present embodiment preferably arranges basic unit 1 and is coated with wearing layer 4, prevents waste pipe from occurring scratch when installing or use.
Be provided with silicon core layer 3 in described foam layer 2, silicon core layer 3, foam layer 2 and basic unit 1 are by being glued to one; The present embodiment preferably arranges on silicon core layer 3 and is provided with some fin 3-1, improves the bearing capacity of waste pipe.
Certainly; just the preferred embodiment of the utility model is described in detail by reference to the accompanying drawings above; not limit practical range of the present utility model with this; all equivalence changes done according to principle of the present utility model, structure and structure, all should be covered by protection domain of the present utility model.
