Description
Technical field
The utility model relates to a kind of flexible pipe.
Background technique
The application of flexible pipe covers each industrial production manufacture and field of circulation, be widely used in the industries such as oil, chemical industry, boats and ships, dock, tank car, agricultural, food, beverage, medicine, and hot and cold water, steam, ventilation, cooling, fire-fighting, hydraulic pressure, medium is as gas, water, mist, muddy water, sand grains, abrasive grit etc. All aspects of.As water delivery hose: for aspects such as irrigation, gardening, building, fire-fighting, equipment and tank car cleaning, agricultural fertilizer, ight soil, industrial sewage drainings; Hot water and vapor hose: for chiller plant cooling water, engine engine hot and cold water, food processing, the especially hot water of Milk Products Plant and saturated vapour aspect.Due to the diversity of flexible pipe institute applied environment, flexible pipe easily weares and teares or is fractureed.
Model utility content
In order to overcome the deficiencies in the prior art, technical problem to be solved in the utility model improves the serviceability of flexible pipe, makes it more firm.
For solving the problem, the technological scheme that the utility model adopts is as follows: a kind of flexible pipe, comprise body, body comprises the internal layer and skin that are smooth surface, internal layer from inside outwards comprises fluoroplastics layer and layer of silica gel successively, and fluoroplastics layer and layer of silica gel are fixed by silica gel binder, are provided with spiral helicine hollow channel between internal layer and skin, be provided with the supporting bar with its synchronous screw in hollow channel, between internal layer and hollow channel, be provided with at least one deck fleece.
Preferably: between skin and hollow channel, be provided with at least one deck fleece.
Preferably: the cross section profile of hollow channel is circular.
Preferably: the cross section profile of hollow channel is square.
Preferably: fibroreticulate material is polyster fibre or aramid fibre.
Preferably: the material of supporting bar is metal.
Preferably: the material of supporting bar is PVC or PE or PP.
Compared to existing technology, the beneficial effects of the utility model are: the surface energy that internal layer is level and smooth reduces the resistance that flexible pipe suffers when carrying gas, fluid, improves transfer efficiency; Outer level and smooth surface energy reduces flexible pipe and the frictional force suffered by other object contacts, also facilitates the applicable angle of adjustment flexible pipe while lowering wearing and tearing.Spiral hollow channel ensure that the ductility of flexible pipe, and supporting bar and fleece strengthen its fastness, by energetically pull or weight pushes down time, both can reinforced hose deformation anti-pressure abilities, reduce the probability damaged.Fluoroplastics layer has excellent chemical-resistant, and its impact strength is high, and flexible pipe applicability strengthens.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is longitudinal profile schematic diagram of the present utility model.
In figure, mark is described as follows:
1, body; 2, hollow channel; 3, fluoroplastics layer; 4, layer of silica gel; 5, fleece; 6, outer; 7, supporting bar.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1-2, a kind of flexible pipe, comprise body 1, body 1 comprises the internal layer and outer 6 that are smooth surface, internal layer from inside outwards comprises fluoroplastics layer 3 and layer of silica gel 4 successively, and fluoroplastics layer 3 and layer of silica gel 4 are fixed by silica gel binder, is provided with spiral helicine hollow channel 2 between internal layer and outer 6, be provided with the supporting bar 7 with its synchronous screw in hollow channel 2, between internal layer and hollow channel 2, be provided with at least one deck fleece 5.
Be provided with at least one deck fleece 5 between outer 6 and hollow channel 2, the internal and external layer of body all arranges fleece and strengthens overall flexibility.
The cross section profile of hollow channel 2 is circular or square, and two kinds of shapes are comparatively simple, and process is less.
Fibroreticulate material is polyster fibre or aramid fibre.Terylene is an important kind in synthetic fiber, is the trade name of China's polyester fibre.It is with p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) for raw material is through esterification or ester exchange and polycondensation reaction and obtained fiber-forming polymer---PETG (PET), through the fiber that spinning and reprocessing are made.Aramid fiber full name is PPTA, a kind of novel high-tech synthetic fiber, there is superhigh strength, high-modulus and high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight, its intensity is 5 ~ 6 times of steel wire, and modulus is 2 ~ 3 times of steel wire or glass fibre, and toughness is 2 times of steel wire, and weight is only about 1/5 of steel wire, at the temperature of 560 degree, do not decompose, do not melt.It has good insulating properties and aging quality resistance, has very long life cycle.
The material of supporting bar is metal, preferably adopts steel wire.Its tolerance of the supporting bar of metal material is more powerful.The material of supporting bar is PVC or PE or PP.PVC＝polyvinyl chloride, English abbreviation PVC, maximum feature is fire-retardant. polyethylene (polyethylene, be called for short PE) be that ethene is through being polymerized obtained a kind of thermoplastic resin, there is excellent resistance to low temperature (minimum serviceability temperature can reach-100 ~-70 DEG C), chemical stability is good, the erosion (the not resistance to acid with oxidizing property) of the most of soda acid of ability.Be insoluble to common solvent under normal temperature, moisture absorption is little, and electrical insulating property is excellent.PP, chemical name: polypropylene, its density is little, intensity and toughness, and hardness heat resistance is all better than low pressure polyethylene, can about 100 degree uses, has good electrical property and high-frequency insulation not by humidity effect, but become fragile during low temperature, not wear-resisting, easily aging.
Above-mentioned mode of execution is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
