Abstract
The utility model provide a kind of can the rubber hose of resistance to positive/negative-pressure, comprise inner glue layer from inside to outside, enhancement layer, face glue-line, it is characterized in that: be smooth tube inside described inner glue layer, outside is the thread protrusion extended along pipeline axial; Described enhancement layer forms by steel wire winding layer being coated with folder cloth winding layer; The steel wire of described steel wire winding layer is wound around along the groove between thread protrusion.The beneficial effects of the utility model are: the utility model is by the steel wire of certain diameter, be wound on inner glue layer with that be suitable for, uniform stroke, use Filament-wound Machine or the fabric spooling of 1 layer or 2 layers again, when reach can ensure negative pressure, improve the ability that sebific duct bears malleation further; The working pressure of the product of this structure can reach 4.0MPa, and minimum bending radius is only original half.
Description
Technical field
The utility model relates to a kind of rubber hose, especially a kind of can the rubber hose of resistance to positive/negative-pressure.
Background technique
Along with the development of science and technology, the automaticity of all trades and professions is more and more higher, and the application of hydraulics is also more and more wider, and all kinds of machinery is all being improved for raising the efficiency, supporting low pressure hose, often require to increase exponentially working pressure, the bore of conveying is increasing, and complete machine structure is more and more compacter, this just require supporting sebific duct more lightly, more soft, under the prerequisite of guaranteed flow, require that the bending radius of rubber hose is little, and dual-purpose is inhaled by the row of requirement.
Existing supporting low pressure hose mostly is folder cloth structure, it uses folder cloth as reinforcing material, need many layers to press from both sides cloth enhancing and just can reach working pressure, and pressure (being generally 1.0MPa or 1.5MPa) on the low side, rubber tube body is heavy, bending radius large (generally reaching the 15-20 of sebific duct internal diameter doubly), and sebific duct length is also shorter, can not meet the demand in market, belong to the infrastructure product eliminated gradually.At present, the suction rubber tube of resistance to positive/negative-pressure progressively can replace fabric hose, but there is easy delamination, problem that bending radius is larger in suction rubber tube, can not meet more lightly, more soft requirement.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of light and handy soft, bending radius is little, and what be not easy delamination can the low pressure rubber hose of resistance to positive/negative-pressure.
The technical solution of the utility model is: a kind of can the rubber hose of resistance to positive/negative-pressure, comprise inner glue layer from inside to outside, enhancement layer, face glue-line, it is characterized in that: be smooth tube inside described inner glue layer, outside is the thread protrusion extended along pipeline axial; Described enhancement layer forms by steel wire winding layer being coated with folder cloth winding layer; The steel wire of described steel wire winding layer is wound around along the groove between thread protrusion.
Steel wire winding layer is Coppered Steel Wire winding layer, and described inner glue layer is made up of nitrile rubber and neoprene.
Described folder cloth winding layer is the combination of the fiber winding layer of 1-2 layer or the fabric winding layer of 1-2 layer or fiber winding layer and fabric winding layer.
The beneficial effects of the utility model are: the present invention is by the steel wire of certain diameter, be wound on inner glue layer with that be suitable for, uniform stroke, use Filament-wound Machine or the fabric spooling of 1 layer or 2 layers again, when reach can ensure negative pressure, improve the ability that sebific duct bears malleation further; The working pressure of the product of this structure can reach 4.0MPa, and minimum bending radius is only original half.
Accompanying drawing explanation
Fig. 1 be of the present utility model can the rubber hose structural representation of resistance to positive/negative-pressure
1-inner glue layer, 2-enhancement layer, 3-face glue-line, 11-thread protrusion, 12-groove, 21-steel wire winding layer, 22-press from both sides cloth winding layer
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, a kind of can the rubber hose of resistance to positive/negative-pressure, comprising inner glue layer 1 from inside to outside, enhancement layer 2, face glue-line 3, is smooth tube inside described inner glue layer 1, and outside is the thread protrusion 11 extended along pipeline axial; The support performance of sebific duct in the thread protrusion 11 in outside can play and strengthen, the groove 12 simultaneously formed between thread protrusion 11 can coordinate better with outer field steel wire, reduce because the stress of the different joint interface caused of telescopicing performance between different materials, and then reduce the possibility of the inner intermediate peeling of sebific duct.
Described enhancement layer 2 forms by steel wire winding layer 21 being coated with folder cloth winding layer 22; The steel wire of described steel wire winding layer 21 is wound around along the groove 12 between thread protrusion 11, when reach can ensure negative pressure, improve further the ability that sebific duct bears malleation.
Steel wire winding layer 21 is Coppered Steel Wire winding layer 21, and described inner glue layer 1 is the inner glue layer 1 be made up of nitrile butadiene rubber and neoprene.
Described folder cloth winding layer 22 is the combination of the fiber winding layer of 1-2 layer or the fabric winding layer of 1-2 layer or single layer fibre winding layer and flat woven fabric winding layer.
The present invention, by the steel wire of certain diameter, is wound on inner glue layer with suitable, uniform stroke, then uses Filament-wound Machine or the fabric spooling of 1 layer or 2 layers, when reach can ensure negative pressure, improve the ability that sebific duct bears malleation further; The working pressure of the product of this structure can reach 4.0MPa, and minimum bending radius is only original half.
What describe in above-described embodiment and specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
