At present, plastic tube is widely used in the fields such as building water supply and drainage, cities and towns plumbing and fuel tube, becomes the main force of new century urban construction pipe network.UPVC pipe is that a kind of to take PVC=polyvinyl chloride (PVC) resin be raw material, not the plastic tube of plasticizer-containing.Along with the development of chemical industry technology, the performance of the standby general PVC=polyvinyl chloride of UPVC pipe, has increased again the advantage that corrosion resistance and ductility are good, thereby has been specially adapted to water supply network; And because it is non-conductive,, with acid, alkali, salt generation electrochemical reaction, so reduced corrosion, do not make it not need outer anti-corrosive coating and liner; UPVC pipe also possesses ductility, and it can produce surrender and not break under load action, has overcome this shortcoming of plastic tube fragility in the past.
Model utility content
The purpose of this utility model is, a kind of low density lightweight UPVC tubing is provided, elastic reinforcement, and density reduces, and quality is light, has certain flexibility simultaneously, also has higher withstand voltage properties, and can prevent the phenomenons such as pipeline incrustation, tongue green for a long time and obstruction.
The technical solution of the utility model is:
A kind of low density lightweight UPVC tubing, comprise modified polyvinyl chloride layer, modified polyvinyl chloride material pliability is good, inner wall smooth, fluid flow loss is little, dirt is difficult for being attached on smooth tube wall, be convenient to maintenance, cost of upkeep is low, in described modified polyvinyl chloride layer is provided with, two-layer outward, in described, between between outer two-layer modified polyvinyl chloride layer, be provided with cavity, in described cavity, be provided with some connecting walls, described connecting wall is circumferentially uniformly distributed along cavity, in described in described connecting wall is connected to, between between outer two-layer modified polyvinyl chloride layer, thereby described cavity is divided into some cells, in described connecting wall, be enclosed with steel wire, described connecting wall is kept straight on and is arranged or spiral winding setting along the length direction of described tubing, is preferably spiral winding setting, owing to cavity being divided into some cells, thereby make the elastic reinforcement of body, density reduces, quality is light, has certain flexibility simultaneously, by steel wire is set in connecting wall, increased the rigidity of tubing, had higher withstand voltage properties, its withstand voltage properties of the steel wire of spiral winding is stronger.
Further, described steel wire is grid type steel wire; Described grid type steel wire is rectangular mesh shaped steel silk screen or network shaped steel silk screen, described rectangular mesh shaped steel wire network framework comprises spiral wire and parallel steel wire, described network shaped steel silk screen comprises left hand screw steel wire and right-hand screw steel wire, thereby has improved intensity and the toughness of product.
Further, one side of described steel wire is also provided with the steel bar extending along connecting wall, for when wire bonding as steel wire being docked to the joint that is welded into skeleton, improved the problem that steel wire mesh frame is easily subjected to displacement, greatly strengthened the bearing capacity of composite pipe.
Further, described outer modified polyvinyl chloride layer outer surface inner side is also provided with steel rib reinforcing band, can cross the method for moulding by two ribs or many ribs and produce tapping rib reinforcing band, the outer surface that described steel rib reinforcing band is wrapped in composite pipe with single-screw method forms steel rib enhancement layer, thereby further improved the ring stiffness of product, strengthen the bearing capacity of composite pipe, there is again certain pliability.
Further, in described cell, can also fill vinyl chloride secondary recovery particle, further improve the ring stiffness of product, strengthen the bearing capacity of composite pipe, there is again certain pliability.
Further, the inner side of described internal layer modified polyvinyl chloride layer is provided with drainage blanket, and described drainage blanket is organic silicon hydrophobic layer, can make the surface friction drag of inwall and water extremely low, effectively reduces loss of head, and prevents the phenomenons such as pipeline incrustation, tongue green for a long time and obstruction.
The utility model has the advantage of: elastic reinforcement, density reduces, and quality is light, has certain flexibility simultaneously, also has higher withstand voltage properties, and can prevent the phenomenons such as pipeline incrustation, tongue green for a long time and obstruction.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
