Description
Technical field
This utility model relates to a kind of polyethylene tube, and specifically a kind of high density polyethylene pipe workpiece for water supply, belongs to polyethylene tube field.
Background technology
The pipeline used in current municipal drainage facility, mostly is plastic structure wall pipe, but the ring stiffness of plastic structure wall pipe is relatively low, and unit rice weight is also relatively big, and throughput rate is low, and additionally strip junction is thin, and intensity is low, and ring flexibility is poor, has layering, disengages phenomenon and produces.The demand of the urban construction developed rapidly can not be met.But, the seriously corroded that existing buried water-drainage tube part exists, constructional difficulties, intensity is relatively low, and is susceptible to blocking, and broken, service life is shorter, etc. problem.
Utility model content
In order to solve the problems referred to above, this utility model devises a kind of high density polyethylene pipe workpiece for water supply, not only has higher pressure performance, and corrosion-resistant, is not easily blocked, and intensity is high, long service life.
The technical solution of the utility model is:
A kind of high density polyethylene pipe workpiece for water supply, including the plastic outer layer made with polyethylene and inner plastic, one layer of winding steel wire layer integrally it is bonded with by hot melt adhesive layer between described plastic outer layer and inner plastic, thus not only making product have higher pressure performance, intensity is high, and connect fixation, not easily it is layered, long service life；Described winding steel wire layer includes the meshy steel wire skeleton that two-layer respectively left-and-right spiral is Wrapping formed, and internal pressure-resistant is high, and flexibility is good, and the life-span is long；The outer felt of described plastic outer layer is wound with glass layer, and described glass layer is to be soaked into unsaturated polyester resin by glass fiber to be entwined, and not only high insulating effect is not easily frozen brokenly, and intensity is high；It is welded with a plurality of enhancing steel band along length direction between meshy steel wire skeleton described in two-layer, improves the problem that steel wire mesh frame is easily subjected to displacement, greatly strengthen the bearing capacity of multiple tube, make the intensity of product be greatly improved.
Further, the inner side of described inner plastic is provided with hydrophobic layer, and described hydrophobic layer is organic silicon hydrophobic layer, it is possible to makes feed pipe inwall extremely low with the frictional resistance of water, effectively reduces the loss of flood peak, and prevent the phenomenons such as supply line dirty, tongue green for a long time and blocking.
Further, the outside of described glass layer is provided with quartz sand particle layer, improves rigidity and the compressive resistance of product, and wearability is good, not easy to wear.The quartz sand size of described quartz sand particle layer is sized to 100-200 order, it is preferred to 150 orders.
Further; by binding agent such as polyurethane, melt viscosity with light tight film outside described quartz sand particle layer; such as black polyethylene film; the outer application of described light tight film has primary antibodie UV protective layers; make tubing be black by light tight film, not there is printing opacity effect, it is to avoid growth algae thing and the problem that causes secondary pollution and line clogging on the medial wall of tubing after life-time service; the long-term safety being conducive to pipeline uses, and extends service life.
Additionally, the inner side of described internal layer is provided with electrical heating wire, one end of tubing is provided with the temperature sensor being close to described outer layer, the temperature of temperature sensor measurement tube material and tube wall also controls the connecting and disconnecting of the circuit of electrical heating wire, the other end of tubing is provided with the plug electrically connecting with described electrical heating wire and being positioned at outside tubing, it is thus possible to effectively prevent water pipe from freezing crack, and saves energy.
The utility model has the advantage of: not only there is higher pressure performance, and corrosion-resistant, it being not easily blocked, intensity is high, long service life.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the radial cross-section of this utility model embodiment composite pipe.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains this utility model, be not used to limit this utility model.
Embodiment 1
As shown in Figure 1, a kind of high density polyethylene pipe workpiece for water supply, including the plastic outer layer 1 made with polyethylene and inner plastic 2, one layer of winding steel wire layer 4 integrally it is bonded with by hot melt adhesive layer 3 between described plastic outer layer 1 and inner plastic 2, thus not only making product have higher pressure performance, intensity is high, and connects fixation, not easily it is layered, long service life；Described winding steel wire layer 4 includes the meshy steel wire skeleton that two-layer respectively left-and-right spiral is Wrapping formed, and internal pressure-resistant is high, and flexibility is good, and the life-span is long；The outer felt of described plastic outer layer 1 is wound with glass layer 5, and described glass layer 5 is to be soaked into unsaturated polyester resin by glass fiber to be entwined, and not only high insulating effect is not easily frozen brokenly, and intensity is high；It is welded with 4 along length direction between meshy steel wire skeleton described in two-layer and strengthens steel band 6, improve the problem that steel wire mesh frame is easily subjected to displacement, greatly strengthen the bearing capacity of multiple tube, make the intensity of product be greatly improved.
The inner side of described inner plastic 2 is provided with hydrophobic layer 7, and described hydrophobic layer is organic silicon hydrophobic layer, it is possible to makes feed pipe inwall extremely low with the frictional resistance of water, effectively reduces the loss of flood peak, and prevent the phenomenons such as supply line dirty, tongue green for a long time and blocking.
The outside of described glass layer is provided with quartz sand particle layer, improves rigidity and the compressive resistance of product, and wearability is good, not easy to wear.The quartz sand size of described quartz sand particle layer is sized to 100-200 order, it is preferred to 150 orders.
By binding agent such as polyurethane, melt viscosity with light tight film outside described quartz sand particle layer; such as black polyethylene film; the outer application of described light tight film has primary antibodie UV protective layers; tubing is made to be black by light tight film; not there is printing opacity effect; after avoiding life-time service, the medial wall of tubing grows algae thing and cause the problem of secondary pollution and line clogging, be conducive to the long-term safety of pipeline to use, extend service life.
