Abstract
The utility model relates to a composite tube which comprises an inner layer, a metal composite layer and an outer layer, wherein the metal composite layer is located between the inner layer and the outer layer. The composite tube is characterized in that the metal composite layer is made of metal wires spirally wound on the inner layer. The metal wires are spirally and closely arranged between the inner layer and the outer layer. Two glue bonding layers are respectively arranged between the metal composite layer and the inner layer and between the metal composite layer and the outer layer. The metal wires are steel wires. The composite tube disclosed by the utility model has the beneficial characteristics of high strength and simple structure, is capable of eliminating static electricity, and is convenient to manufacture.
Description
Technical field
The utility model is related to a kind of building pipe, more particularly to a kind of multiple tube.
Background technology
With the continuous progress of industry, various types of transport of cement pipes emerge in an endless stream, but are broadly divided into two classes, one class is that, mainly for delivery of oxygen, acetylene gas etc., its intensity is general using cotton thread as the rubber woven tube of middle skeleton, but be not suitable for conveying liquid substances, such as cement concrete；It is another kind of, it is steel wire rubber woven tube, skeleton is the wire netting by braiding in the middle of this kind of rubber tube, intensity is big, bearing capacity is strong, but preparation technology is complicated, easy degumming between wire netting and rubber layer, service life is shorter, it is not easy to bend, and is generally used for the conveying of highly pressurised liquid.At present, under normal pressure and low-pressure state, the conveying of cement concrete typically uses PA tube plastic tube, and this pipe fitting has comprehensive advantage because of it in terms of health, heatproof, pressure-resistant, toughness, and in China, every field is widely used in a variety of applications.But PA tube plastic tube is the shortcomings of have inadequate, frangible tension, compression strength, electrostatic precipitation, pipe shaft is easily broken, easily produces Electrostatic Absorption dirt during use.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of multiple tube simple in construction, easy to make, moderate strength, oil resistant antistatic.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：A kind of multiple tube, it is characterised in that：Including nitrile rubber internal layer, metal composite layer and nitrile rubber outer layer, metal composite layer is located between nitrile rubber internal layer and nitrile rubber outer layer, and metal composite layer is the wire being spirally wound on nitrile rubber internal layer, and the wire is diameter 1mm steel wire.Internal layer and outer layer of the present utility model use nitrile rubber material, can play good oil resistivity and resistance hardening, in the environment of conveying cement concrete, long service life.
Neoprene adhesive layer is equipped between metal composite layer and the nitrile rubber internal layer and nitrile rubber outer layer, the thickness of the neoprene adhesive layer is 0.6mm.The thickness of neoprene adhesive layer is less than steel wire diameter, will not produce very strong stress point during multiple tube bending, neoprene adhesive layer is good with wire bonding effect, it is not easy to degumming.
The thickness of the nitrile rubber internal layer is less than the thickness of nitrile rubber outer layer.Nitrile rubber outer layer easily weares and teares, and the loss of nitrile rubber internal layer is smaller, and such setting can balance the loss time of inside and outside layer, in the case where ensureing product service life, reduces manufacturing cost.
Certainly, the wire that the utility model is used can also be a diameter of 1.5mm copper wire or a diameter of 1mm Al-alloy metal silk.
The utility model is wrapped in inner layer outer wall as metal composite layer using wire, wire is arranged closely between internal layer and outer layer in the shape of a spiral, and neoprene adhesive layer is equipped between wire and internal layer and outer layer, so wire can be densely combined together with internal layer and outer layer, so that multiple tube bulk strength becomes big, and the electrostatic produced during multiple tube use can be eliminated.The utility model is simply wound by wire, just uniformly densely metal composite layer can be formed between inner tube layer and outer layer compound, is not only simple in structure, and convenient manufacture.
In summary, the utility model has the beneficial effect of oil resistant antistatic simple in construction, easy to make, moderate strength, is highly suitable for conveying the cement concrete under normal pressure and low-pressure state.

Embodiment
As shown in Figure 1 and Figure 2, a kind of multiple tube, including nitrile rubber internal layer 1, metal composite layer 2 and nitrile rubber outer layer 4, metal composite layer 2 is located between nitrile rubber internal layer 1 and nitrile rubber outer layer 3, and metal composite layer 2 is the steel wire for a diameter of 1mm being spirally wound on nitrile rubber internal layer 1.Wire is arranged closely between nitrile rubber internal layer 1 and nitrile rubber outer layer 3 in the shape of a spiral.The neoprene adhesive layer 4 that thickness is 0.6mm is equipped between metal composite layer 2 and nitrile rubber internal layer 1 and nitrile rubber outer layer 3.Neoprene adhesive layer 4 make that metal composite layer 2 and nitrile rubber internal layer 1 and nitrile rubber outer layer 3 bond more firmly, multiple tube bulk strength is moderate.The thickness of the nitrile rubber internal layer 1 is 5mm, and the thickness of the nitrile rubber outer layer 3 is 8mm.
