Abstract
The utility model discloses a high tenacity PVC U cover spool material, including a pipe body, be provided with the steel band in the body, axial spiral winding is followed to the steel band, the cross -section of steel band is semi -circular, the steel band has cup jointed the PE pipe cover outward, the pipe box with the body heat seal together, the body is inside to be equipped with many strengthening ribs along length direction, the cross section of strengthening rib is described for the gear, the utility model has the advantages of: high temperature resistant, toughness is high, and compressive property is good, and two -layer pipe wall combines firmly inside and outside moreover, has improved product strength, has prolonged life.
Description
Technical field
The utility model relates to a kind of set spool, specifically a kind of high tenacity PVC-U set line pipe, belongs to set spool field.
Background technology
PVC-U pipe has that resistance to corrosion is strong, be prone to the advantage such as bonding, price is low, quality is hard, is a kind of synthetic material pipe being widely used in public waterworks, electrical engineering, architectural engineering, sewerage, communication engineering.The Chinese utility model patent of entitled " a kind of PVC-U overlaps line pipe " Application No. " 201410704373.7 " discloses a kind of PVC-U and overlaps line pipe, including supervisor, also include the least one set auxiliary pipe along the axis direction laying of described supervisor, described auxiliary pipe includes pipe shaft and carries the base of described pipe shaft, described base is fixed on the outer tube wall of described supervisor, and described pipe shaft is fixed on described base.But, the toughness of this product is the most relatively low, and heat-resisting quantity is poor, and service life is shorter.
Utility model content
In order to solve the problems referred to above, the utility model devises a kind of high tenacity PVC-U set line pipe, and high temperature resistant, toughness is high, and compressive property is good, and inside and outside two-layer tube wall is firmly combined with, and improves product strength, extends service life.
The technical solution of the utility model is:
A kind of high tenacity PVC-U set line pipe, including body, is provided with steel band in described body, described steel band spiral winding vertically, the cross section of described steel band is semicircle, and toughness is high, elastic big, connect fixation, service life is long, and is easy to overlap line, is socketed with polyethylene pipe set outside described steel band, together with described pipe box is heat sealing at described body, so that connecting more firm.
By being provided with the most vertically by the equally distributed steel band of corrugated between inner tube and outward corrugated tube, the cross section of steel band is arc-shaped, the toughness of this bellows it is greatly enhanced by the design of undulatory steel band, and the stress of inner tube and outward corrugated tube can carry out the buffering of elasticity by undulatory steel band, improve bellows in the face of the resistance of impact, the intensity of this bellows of General Promotion.
Further, described tubular body is provided with a plurality of reinforcement along its length, and the cross section of described reinforcement is gear-like, the more common reinforcement of gear-like reinforcement, having higher ductility, it is big with the contact area of tubing simultaneously, substantially enhances impact resistance and the toughness of tubing.
Further, the outside of described body is provided with layer of polyurethane, further increases heat insulation effect, and the outside of described layer of polyurethane is provided with quartz sand particle layer, improves rigidity and the compressive resistance of product, and wearability is good, the most easy to wear.The quartz sand size size of described quartz sand particle layer is 100-200 mesh, preferably 150 mesh.
Further, the outside of described quartz sand particle layer is provided with polyether-ether-ketone layer, it is possible to high temperature resistant, imitates anticorrosion, extends service life.
The utility model has the advantage of: high temperature resistant, toughness is high, and compressive property is good, and inside and outside two-layer tube wall is firmly combined with, and improves product strength, extends service life.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
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 the utility model, be not used to limit the utility model.
Embodiment 1
As it is shown in figure 1, a kind of high tenacity PVC-U set line pipe, including hard polyethylene body 1, described hard polyethylene body is modified polyvinyl chloride material, is provided with steel band 2, described steel band 2 spiral winding vertically in described body 1, the cross section of described steel band 2 is semicircle, and toughness is high, elastic big, connect fixation, service life is long, and is easy to overlap line, is socketed with polyethylene pipe set outside described steel band 2, together with described pipe box is heat sealing at described body, so that connecting more firm.
By being provided with the most vertically by the equally distributed steel band of corrugated between inner tube and outward corrugated tube, the cross section of steel band is arc-shaped, the toughness of this bellows it is greatly enhanced by the design of undulatory steel band, and the stress of inner tube and outward corrugated tube can carry out the buffering of elasticity by undulatory steel band, improve bellows in the face of the resistance of impact, the intensity of this bellows of General Promotion.
Described body 1 is internal is provided with a plurality of reinforcement 3 along its length, the cross section of described reinforcement 3 is gear-like, the more common reinforcement of gear-like reinforcement, has higher ductility, it is big with the contact area of tubing simultaneously, substantially enhances impact resistance and the toughness of tubing.
The outside of described body 1 is provided with layer of polyurethane 4, further increases heat insulation effect, and the outside of described layer of polyurethane 4 is provided with quartz sand particle layer, improves rigidity and the compressive resistance of product, and wearability is good, the most easy to wear.The quartz sand size size of described quartz sand particle layer is 100-200 mesh, preferably 150 mesh.
The outside of described quartz sand particle layer is provided with polyether-ether-ketone layer, it is possible to high temperature resistant, imitates anticorrosion, extends service life.
