Abstract
The utility model provides a kind of new type high temperature air hose, it includes rubber inner tube, and soft anti-stab protective layer is arranged outside the rubber inner tube, and the light wire drawing braiding enhancing jacket layer of stainless steel is arranged outside the soft anti-stab protective layer.Utility model not only has high temperature resistant, suitable for conveying high temperature compressed air in commercial vehicle, and it is wear-resisting, anti-burst performance height, tube body flexibility and globality are more preferable.
Description
Technical field
The utility model relates to new type high temperature air hoses.
Background technique
High temperature air hose is mainly used in the commercial vehicles such as bus, heavy truck, for conveying high temperature compressed air, uses temperature
Degree is usually all at 200 DEG C or so.There are mainly two types of structures for high temperature air hose currently used in the market: one is interior effective poly-
The structure of stainless steel wire is compiled outside tetrafluoroethene, the tube body of the structure is very hard, since the surface of polyfluortetraethylene pipe is very smooth, institute
The stainless steel wire compiled in addition is to separate with inner tube, cause tube body cutting head when steel wire due to dissipate flower and can not fitting joint, separately
Outside, polytetrafluoroethylene (PTFE) belongs to plastics, almost without elasticity, so sealing is poor；Another kind is outside interior effective corrugated stainless steel tubing
The structure of stainless steel wire is compiled, the tube body of this structure is very hard, needs to connect with welding manner with two end connectors, tube body leaks
Frequency it is very high.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can not only high temperature resistant and tube body flexibility and whole
The better new type high temperature air hose of body.For this purpose, the utility model uses following technical scheme:
New type high temperature air hose, it is characterised in that it includes rubber inner tube, is arranged outside the rubber inner tube soft anti-stab
The light wire drawing braiding enhancing jacket layer of stainless steel is arranged in protective layer, the soft anti-stab protective layer outside.
Further, the soft anti-stab protective layer protects jacket layer using fibrage.
Further, the count of the fibrage protection jacket layer is 93%.
Further, the count of fibrage protection jacket layer is greater than the braiding of the light wire drawing braiding enhancing jacket layer of stainless steel
Density.
Due to using the technical solution of the utility model, utility model not only has high temperature resistant, is suitable for defeated in commercial vehicle
High temperature compressed air is sent, and wear-resisting, anti-burst performance height, tube body flexibility and globality are more preferable.
Detailed description of the invention
Fig. 1 provides the structural schematic diagram of embodiment by the utility model.
Specific embodiment
Referring to attached drawing 1, which is the structural schematic diagram after peeling off the provided embodiment of the utility model layer by layer.This is practical
New type high temperature air hose includes rubber inner tube 1, and soft anti-stab protective layer, soft anti-stab guarantor is arranged outside the wave rubber inner tube 1
The light wire drawing of stainless steel is arranged outside and weaves jacket layer 3 for the preferred fiber protection braiding jacket layer 2 of sheath, the soft anti-stab protective layer.
Rubber inner tube 1 preferably uses ternary fluororubber, and with excellent hot air aging, oil resistant and resistant to chemical media are rotten
Corrosion energy, heatproof peak value is up to 260 DEG C, and the rubber is not required to carry out post vulcanization, greatly reduces production cost and two
The exhaust emission that section vulcanization generates.Fiber protection braiding jacket layer 2 selects 1414 aramid lines of contraposition to weave, 1414 aramid lines tool
Have the advantages that high temperature resistant, lower shrinkage, intensity are high, fire-retardant, the count of fiber protection braiding jacket layer 2 is 93%, can not only be protected
Rubber inner tube 1 prevents the outer fracture of wire for compiling stainless steel wire from piercing through inner tube, and do braiding layer with line to increase surface rough overshoot, prevents
Only outer stainless steel wire of compiling produces relative sliding, and guarantees the overall performance of tube body.The light wire drawing braiding jacket layer 3 of stainless steel is selection 304
The light wire drawing of stainless steel wire, the steel wire is between soft state and hard state stainless steel wire, the flexibility of existing soft state steel wire, and has hard state
The intensity of steel wire, fibrage protect the count of jacket layer to be greater than the count that the light wire drawing of stainless steel weaves enhancing jacket layer.
The count of the light wire drawing braiding jacket layer 3 of stainless steel is 90%.
The manufacturing step of the utility model is as follows:
The first step, rubber inner tube 1 are squeezed out using the Φ 90mm cold feed extruder of T-type head, are directly coated to 20 meters long
Iron core on, it is necessary to it is bad to prevent inner tube from gluing through subcooled water spraying cooling.
Second step first combines aramid line, then weaves on 24 ingot fibrage machines in outside rubber inner tube 1, is formed fine
Maintenance shield weaves jacket layer 2, and the fiber coverage rate outside count namely tube body is 93%.
The light wire drawing of more stainless steels is combineeed, then protects wired tube in fiber on 36 ingot wire knitting machines by third step
It being woven outside layer 2, forms the light wire drawing of stainless steel and weave jacket layer 3, braided steel wire density is 90%, not only guaranteed the burst strength of tube body, but also
It can make steel wire floor surfacing.
4th step, vulcanization.
5th step, depoling, pressure testing.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, in the field of the utility model, made changes or modifications all cover practical new at this any those skilled in the art
Among the protection scope of type.
