Abstract
The utility model discloses a high temperature resistant, high tenacity PVC U double -walled bellows, there is the outer bellows of heliciform corrugated polyethylene including hard polyethylene inner tube and outer parcel, inner tube and outer ripple intertube be provided with the steel band, axial spiral winding is followed to the steel band, the cross -section of steel band is oval, the steel band has cup jointed the PE pipe cover outward, the pipe box with inner tube and outer bellows respectively the heat seal be in the same place, the outside surface of outer bellows is equipped with the polyether ether ketone layer, 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 bellows, a kind of high temperature resistant, high tenacity PVC-U double-wall corrugated pipe, belongs to bellows field.
Background technology
Plastic film capicitor product is attractive in appearance, Portable durable, it is widely used in multiple fields, through the development of nearly 30 years, the most relative maturity in terms of equipment, forming technique, technique and raw material, the material of plastic film capicitor is gradually extended to the raw materials such as PE, PP from PVC, and the caliber of plastic film capicitor the most progressively develops to heavy caliber direction.Limited due to plastics self-strength, therefore, the bellows intensity prepared is the most limited.The Chinese utility model patent of entitled " steel band reinforced spiral ripple pipe " Application No. " 201420446263.0 " discloses a kind of steel band reinforced spiral ripple pipe, including inner tube and the outward corrugated tube being wrapped with helical ripple, steel band it is provided with between inner tube and outward corrugated tube, steel band is uniformly distributed by corrugated the most vertically, and the cross section of steel band is arc-shaped.Although improve compressive property to a certain extent, but, toughness 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 temperature resistant, high tenacity PVC-U double-wall corrugated 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 temperature resistant, high tenacity PVC-U double-wall corrugated pipe, including hard polyethylene inner tube and the polyethylene outward corrugated tube being wrapped with helical ripple, between described inner tube and outward corrugated tube, it is provided with steel band, described steel band spiral winding vertically, the cross section of described steel band is oval, toughness is high, elastic big, connects fixation, service life is long, polyethylene pipe set it is socketed with, together with described pipe box is heat sealing at respectively with described inner tube and outward corrugated tube, so that connecting more firm outside described steel band；The outer surface of described outward corrugated tube is provided with polyether-ether-ketone layer so that pipeline has good insulation heat resistance.
By being provided with the steel band being wound around in axial screw between inner tube and outward corrugated tube, the cross section of steel band is circular, the toughness of this bellows it is greatly enhanced by steel band design, 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, the inner side of said inner tube is provided with nano ceramic coat, and described nano ceramic coat is the ceramic nano layer that with the addition of nanometer and high-temperature resistant material, has high temperature resistant, imitates anticorrosion, is not easily susceptible to corrosion in water, extends service life.
Additionally, the tubular body of described bellows is provided with plasticity rod, described plasticity rod is flexible rod, such as elastic rubber-plastic composite material bar, or elastoplast rod, or elastic caoutchouc rod, or modified rubber rod, there is plasticity rod owing to running through in body, when the water in water pipe is because of the RADIAL amount of sky the caused volumetric expansion of cold junction ice, can be dissolved by the radial plastic deformation of flexible rod, " absorption ", thus effectively prevent the bursting by freezing of water pipe.
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 shown in Figure 1, a kind of high temperature resistant, high tenacity PVC-U double-wall corrugated pipe, including hard polyethylene inner tube 2 and the polyethylene outward corrugated tube 1 being wrapped with helical ripple, steel band 3 it is provided with between described inner tube and outward corrugated tube, described steel band spiral winding vertically, the cross section of described steel band 3 is oval, toughness is high, elastic big, connecting fixation, service life is long, is socketed with polyethylene pipe set 4 outside described steel band 3, together with described pipe box 4 is heat sealing at respectively with described inner tube and outward corrugated tube, so that connecting more firm；The outer surface of described outward corrugated tube 1 is provided with polyether-ether-ketone layer so that pipeline has good insulation heat resistance.
By being provided with the steel band being wound around in axial screw between inner tube and outward corrugated tube, the cross section of steel band is circular, the toughness of this bellows it is greatly enhanced by steel band design, 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.
The inner side of said inner tube 2 is provided with nano ceramic coat 5, and described nano ceramic coat 5 is the ceramic nano layer that with the addition of nanometer and high-temperature resistant material, has effect anticorrosion, high temperature resistant, is not easily susceptible to corrosion in water, extends service life.
Claims (2)
1. high temperature resistant, a high tenacity PVC-U double-wall corrugated pipe, it is characterized in that: include hard polyethylene inner tube and be wrapped with the polyethylene outward corrugated tube of helical ripple, it is provided with steel band between described inner tube and outward corrugated tube, described steel band spiral winding vertically, the cross section of described steel band is oval, polyethylene pipe set it is socketed with, together with described pipe box is heat sealing at respectively with described inner tube and outward corrugated tube outside described steel band；The outer surface of described outward corrugated tube is provided with polyether-ether-ketone layer.
