Abstract
The utility model relates to a kind of high-strength PVC steel wire tube.Mainly solve the problem of the ability of existing PVC steel wire tube carrying high negative pressure.Comprise pvc pipe body (1) and steel-wire carcass (2), steel-wire carcass (2) is for helical and be positioned at pvc pipe body (1), it is characterized in that: be provided with glass fiber mesh (3) in pvc pipe body (1), described steel-wire carcass (2) interts in glass fiber mesh (3); The outer wall of described pvc pipe body (1) is evenly provided with annular muscle (4).Add glass fiber mesh in the body of this high-strength PVC steel wire tube and set up stiffening rib at outer wall, effectively improve the ability of carrying negative pressure, the demand used under high negative pressure operating mode can be met, good flexibility can be kept simultaneously, easily bending, to use and easy for installation.
Description
Technical field
The utility model relates to a kind of steel wire tube, is specifically related to a kind of high-strength PVC steel wire tube.
Background technique
Steel wire tube refers in body the sebific duct being provided with steel-wire carcass, is usually used in the industry such as industrial and mineral, agricultural and water conservancy, civil engineering, food, oil, chemical industry, health, mainly bears negative pressure (vacuum) and carry out conveying powder, particle, water, wet goods medium during work.Existing PVC steel wire tube is primarily of steel-wire carcass and pvc pipe body composition, pvc pipe body is the transparent body and has good flexibility, the medium in body can be observed in use, the peak suction that this PVC steel wire tube of nominal diameter 2 inches can carry is-0.08MPa, in order to increase the ability of PVC steel wire tube carrying negative pressure, the means of usual employing are the intensity of increase steel-wire carcass and are thickeied by the sidewall of body, but under the operating mode of high negative pressure (negative pressure reaches-0.1 more than MPa), there will be body to break and the phenomenon departed from steel-wire carcass, thus, the ability of existing PVC steel wire tube carrying high negative pressure, the demand used under being difficult to meet high negative pressure operating mode.If thickeied by the tube wall of PVC steel wire tube, meanwhile also make the Deflection Modulus of Elasticity of body comparatively large, namely rigidity reinforced, flexible poor, not flexible, the inconvenience when using and install.
Model utility content
In order to overcome the deficiency of the ability of existing PVC steel wire tube carrying high negative pressure, the utility model provides a kind of high-strength PVC steel wire tube, add glass fiber mesh in the body of this high-strength PVC steel wire tube and set up stiffening rib at outer wall, effectively improve the ability of carrying negative pressure, the demand used under can meeting high negative pressure operating mode, simultaneously can keep good flexibility, easily bend, to use and easy for installation.
The technical solution of the utility model is: a kind of high-strength PVC steel wire tube comprises pvc pipe body and steel-wire carcass, and steel-wire carcass is helical and is positioned at pvc pipe body, is provided with glass fiber mesh in pvc pipe body, and described steel-wire carcass interts in glass fiber mesh; The outer wall of described pvc pipe body is evenly provided with annular muscle.
The cross section of described annular muscle is semicircular arc, rounding off between the root of annular muscle and the outer wall of pvc pipe body.
The utility model has following beneficial effect: owing to taking such scheme, when using under high negative pressure operating mode, the pressure acted on pvc pipe body is delivered to glass fiber mesh, glass fiber mesh is supported by steel-wire carcass, effectively improve the tensile strength of pvc pipe body, pvc pipe body there will not be and breaks, thus steel-wire carcass can not be made to depart from, detect through experiment, the peak suction that this high-strength PVC steel wire tube of nominal diameter 2 inches can carry is-0.16 more than MPa, compared with the PVC steel wire tube in the background technique of same size, bearing capacity is doubled, the demand used under can meeting high negative pressure operating mode.Annular muscle, while guarantee pvc pipe body 1 has certain flexibility, improves the Rigidity and strength of pvc pipe body, easily bends, and uses and easy for installation.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
1-PVC body in figure, 2-steel-wire carcass, 3-glass fiber mesh, 4-annular muscle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of high-strength PVC steel wire tube comprises pvc pipe body 1 and steel-wire carcass 2, and steel-wire carcass 2 is helical and is positioned at pvc pipe body 1, and be provided with glass fiber mesh 3 in pvc pipe body 1, described steel-wire carcass 2 interts in glass fiber mesh 3; The outer wall of described pvc pipe body 1 is evenly provided with annular muscle 4.Owing to taking technique scheme, when using under high negative pressure operating mode, the pressure acted on pvc pipe body 1 is delivered to glass fiber mesh 3, glass fiber mesh 3 is supported by steel-wire carcass 2, effectively improve the tensile strength of pvc pipe body 1, pvc pipe body 1 there will not be and breaks, thus steel-wire carcass 2 can not be made to depart from, detect through experiment, the peak suction that this high-strength PVC steel wire tube of nominal diameter 2 inches can carry is-0.16 more than MPa, compared with the PVC steel wire tube in the background technique of same size, bearing capacity is doubled, the demand used under can meeting high negative pressure operating mode.Annular muscle 4, while guarantee pvc pipe body 1 has certain flexibility, improves the Rigidity and strength of pvc pipe body 1, easily bends, and uses and easy for installation.
The cross section of described annular muscle 4 is semicircular arc, rounding off between the root of annular muscle 4 and the outer wall of pvc pipe body 1.This structure can avoid stress to concentrate, and increases the ability that pvc pipe body 1 antifatigue is damaged.
Claims (2)
1. a high-strength PVC steel wire tube, comprise pvc pipe body (1) and steel-wire carcass (2), steel-wire carcass (2) is for helical and be positioned at pvc pipe body (1), it is characterized in that: be provided with glass fiber mesh (3) in pvc pipe body (1), described steel-wire carcass (2) interts in glass fiber mesh (3); The outer wall of described pvc pipe body (1) is evenly provided with annular muscle (4).
2. high-strength PVC steel wire tube according to claim 1, is characterized in that: the cross section of described annular muscle (4) is semicircular arc, rounding off between the root of annular muscle (4) and the outer wall of pvc pipe body (1).
