Abstract
A colliery-based reinforced PVC tube belongs to the art of pipe fittings used in coal mines. The technical proposal of the utility model is to produce the colliery-based reinforced PVC tube with strong bearing of the pressure, light weight, the saving of raw materials, and a diameter range of 10-160mm. The utility model is composed of a PVC tube body and a double-layer filar reinforced body, and is characterized in that the internal layer is an electric conducting inner layer (5), the outside of which is arranged separately with a latitudinal steel wire reinforced layer (3), a filar mesh reinforced layer (2), a PVC plastic tube body (4) and an electric conducting outer layer (1), wherein the filar mesh reinforced layer (2) abuts upon the latitudinal steel wire reinforced layer (3). The furthest outer layer rests with the electric conducting outer layer (1). The conducting inner layer and conducting outer layer are in sequence compounded into an integral body. The utility model has the advantages of strong pressure bearing, light weight and the saving of raw materials, and conforms to China National Coal Mine 558.1 Safety Standards and can be made into the colliery-based reinforced PVC tube with the diameter of 10-160mm.
Description
Technical field
Colliery reinforced PVC flexible pipe belongs to underground mine use tubing field.
Background technique
Present domestic colliery has occurred with the report of steel mesh structure enhancing as middle enhancement layer with tubing, generally twines with the also useful steel wire spiral of tubing to be coated with the report of the pre-coating adhesive of EVA as the mesosphere.As disclosed claimant: Gan Guogong in " Chinese patent " on March 27th, 2002, application number: 01247511, the applying date: on September 5 calendar year 2001, the model utility title: spiral wound steel wire strengthens the steel-plastic composite pipe of body, and this spiral wound steel wire strengthens the steel-plastic composite pipe of body.Comprise the polymer continuum that is arranged in tube wall, it is characterized in that having by at least one surface having the steel wire of the adhesive structure layer that Bond or Bond and blend polymer form to do that left-handed and/or dextrorotation is twined and the enhancing body that forms, strengthen body place the polymer continuum and by the adhesive structure layer make steel wire and polymer continuum firm compound be one.Interior bearing capacity height, using scope is wide.But the subject matter that exists is: can only do the tubing of certain-length, can not make the flexible pipe that 50-100 rice can coil, convenient transportation.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, design a kind of blank in related domain of having filled up, make a kind of bearing capacity strong, in light weight, save material, can make the colliery reinforced PVC flexible pipe of 10-160mm bore.
The technological scheme that its technical problem that solves the utility model adopts is: this colliery reinforced PVC flexible pipe, comprise the pvc pipe body, and place double-deck thread enhancing body in the pvc pipe body, it is characterized in that: internal layer is followed successively by broadwise steel wire enhancement layer, mesh-like enhancement layer outward, the PVC plastic tube body for conduction internal layer, conduction internal layer, skin, the mesh-like enhancement layer abuts against with broadwise steel wire enhancement layer, and outermost surface is a skin, and compound continuously is one.
The mesh-like enhancement layer adopts a kind of braiding in finer wire, aramid fiber, terylene or the polypropylene fibre to form.
Compared with prior art, the beneficial effect that the utility model had is: be the mesh-like enhancement layer because internal layer is steel wire broadwise winding layer, skin, compound continuously with pvc pipe body, inside and outside conductive layer is the special design structure of one, most importantly can make flexible pipe, have bearing capacity simultaneously and can reach 0.4-3Mpa by force, bursting pressure reaches 10Mpa; Materials are few, in light weight, cost is low, only are 50% of common tubing; The broadwise steel wire is not subjected to displacement, can take place inwall expand tube phenomenon; Can make 10-160mm bore composite pipe, satisfy the needs of using caliber pipe material under the coal mine with other needs.Have antistatic, flame retardant effect simultaneously and be better than other tubing, corrosion-resistant, high pressure resistant greatly, advantages such as Security is good, the life-span is long, hygienic environment-protecting.Meet national colliery 558.1 safety standards.
Description of drawings
Fig. 1 is that of the present utility model laterally cuing open shown structural representation.Be most preferred embodiment of the present utility model, wherein: 1 skin, 2 mesh-like enhancement layers, 3 broadwise steel wire enhancement layer 4PVC plastic tube bodies, 5 conduction internal layers.
Embodiment
Below in conjunction with accompanying drawing colliery of the present utility model is described further with the reinforced PVC flexible pipe:
With reference to Fig. 1: this colliery reinforced PVC flexible pipe, form by steel wire enhancement layer 3, PVC plastic tube body 4, conductive plastic internal layer 5 that conductive plastic skin 1, the netted enhancement layer 2 of finer wire, broadwise are twined.Conductive plastic internal layer 5 is in PVC plastic tube body 4, and body 4 adopts the PVC plastics, and the netted enhancement layer 2 of finer wire abuts against outside the steel wire enhancement layer 3 of broadwise winding, and the diameter of the netted enhancement layer 2 of finer wire is decided according to the design needs, and outermost surface is a conductive plastic skin 1.Conductive plastic skin 1, conductive plastic internal layer 5 adopt the PVC anti-static material, and PVC plastic tube body 4 is a pvc material.Preparation process is: the netted enhancement layer 2 of steel wire enhancement layer 3, finer wire, PVC plastic tube body 4, conductive plastic skin 1 that conductive plastic internal layer 5, broadwise are twined, continuous firm compound becoming one on the composite pipe production line.
Mesh-like steel wire enhancement layer 2 can adopt a kind of braiding in aramid fiber, terylene or the polypropylene fibre to form according to the design needs.
3 circle spacings of broadwise steel wire enhancement layer are evenly distributed, and arrangement pitch can be according to the different size model, and the varying strength of composite pipe required to set arbitrarily.
Claims (2)
1, colliery reinforced PVC flexible pipe, comprise the pvc pipe body, and place double-deck thread enhancing body in the pvc pipe body, it is characterized in that: internal layer is conduction internal layer (5), outer broadwise steel wire enhancement layer (3), the mesh-like enhancement layer (2), PVC plastic tube body (4) of being followed successively by of conduction internal layer (5), skin (1), mesh-like enhancement layer (2) abuts against with broadwise steel wire enhancement layer (3), and outermost surface is skin (1), and compound continuously is one.
