Description
Technical field
The utility model relates to rubber product technical field, in particular to a kind of wire spirally-wound hose.
Background technique
Wire braided hose is generally used for engineering construction, lifting transport, injection machine, agricultural machinery, lathe and each work
Conveying has petroleum base (such as mineral oil, solubility of certain pressure and temperature in the mechanization of industry department, automation hydraulic system
Oil, hydraulic oil, fuel oil, lubricating oil) liquid, water fluid (such as emulsion, oil-water emulsion, water), gas and liquid transmission
With.Wire braided hose is usually that synthetic rubber internal layer, mesoglea, multilayer steel wire braid and synthetic rubber outer layer are constituted, and is closed
Having at rubber inner layer makes pumped (conveying) medium bear pressure, the effect for protecting steel wire not weather, synthetic rubber outer layer protection steel wire
Injury-free, steel wire floor is framework material, plays humidification.However, this kind of sebific duct, in delivering hydraulic fluid, gas will be saturating
Rubber inner layer is crossed into each layer and causes sebific duct dilatancy, and then splitting occurs, greatly reduce sebific duct uses the longevity
Life.
Utility model content
In view of the deficiencies of the prior art, the technical problem to be solved is that provide a kind of steel wire winding glue for the utility model
Pipe, the residual gas that can be avoided into each interlayer of sebific duct cause sebific duct dilatancy and splitting, delay making for sebific duct
Use the service life.
The utility model is to be addressed above-mentioned technical problem by the following technical programs.
A kind of wire spirally-wound hose, from the inside to the outside successively include rubber inner layer, the first steel wire winding layer, cushion rubber layer,
Second steel wire winding layer and rubber outer are circumferentially evenly equipped with three to four edges on the outer surface of cushion rubber layer axially through opening up
Straight line air channel, the wide cut of straight line air channel is 1mm to 3mm, and the depth of straight line air channel is 0.1mm to 0.5mm, outside rubber
Matched on layer with straight line air channel and be uniformly provided with several external vents, the diameter of external vent be 0.2mm extremely
0.8mm。
Preferably, the first steel wire winding layer and the second steel wire winding layer reverse spiral winding structure each other.
Preferably, spiral angle is 45 degree to 60 degree.
Preferably, the steel wire line footpath of the first steel wire winding layer and the second steel wire winding layer is 0.2mm to 0.8mm.
Preferably, rubber inner layer is NBR, HNBR, NBIR or BIMS rubber material.
Preferably, rubber outer is SBR, CR, EPDM or CSM rubber material.
Preferably, rubber inner layer with a thickness of 0.5mm to 4mm.
Preferably, rubber outer with a thickness of 0.5mm to 3mm.
Preferably, cushion rubber layer with a thickness of 0.2mm to 1mm.
The utility model has the beneficial effects that
1. cushion rubber layer plays a good cushioning role two layers of steel wire winding layer structure, it is ensured that pliability it is same
When, there is excellent bearing capacity and resistance to deflection.
2. the interlayer gas that the straight line air channel opened up on cushion rubber layer can will transmit through rubber inner layer into each layer is arranged
Out, moreover, interlayer gas is expelled to outside in time by external air hole and the cooperation of straight line air channel on rubber outer, effectively
It avoids interlayer gas and causes sebific duct dilatancy and splitting, substantially increase service life.
3. the spiral angle of two layers of steel wire winding layer is different and inversely winds each other, it is beneficial to improve braiding intensity, it is antitorque
Song deformation, improves bearing capacity and resistance to deflection.
