Pipe.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of armouring high-pressure rubber pipe, including inner glue layer, casing play and the outer glue-line set from inside to outside, it is characterised in that：
The casing play is bellows structure；Axially it is evenly equipped with a plurality of buffer bar on the inner glue layer inwall, the buffer bar is along high pressure
The axial direction of sebific duct is set；The outer glue-line is coated with flame-retardant layer, and the flame-retardant layer outer surface is socketed with turn, described
Flame-retardant layer is provided with the spiral tank of putting spring circle, and the turn is in spiral tank and convex in spiral tank.
Further technical scheme is：Enhancement layer is additionally provided between the outer glue-line and flame-retardant layer.
Further technical scheme is：The enhancement layer is helically wound around twining for outer glue-line in the opposite direction including two layers
Winding layer, spiral angle are 50 °, and the winding layer includes the steel wire bar in casing ply and embedded casing ply.
Further technical scheme is：The skeleton layer surface is provided with zinc coat.
Further technical scheme is：The steel wire bar surface is provided with zinc coat.
Further technical scheme is：The gauge of wire of the turn is 1~5mm.
It is using beneficial effect caused by above-mentioned technical proposal：
(1) buffer bar provides enough cushion effects for the highly pressurised liquid that inner glue layer trickles, and alleviates highly pressurised liquid and high pressure
The friction and corrosion of sebific duct inner glue layer inwall, and then improve the life-span of high-pressure rubber pipe；
(2) casing play is bellows structure, can either effectively resist the pressure of ecto-entad, and and can is enough resisted from inside to outside
Pressure, prevent inner glue layer or outer glue-line cracking damage from causing leakage；
(3) flame-retardant layer makes high-pressure rubber pipe have certain anti-flammability, and the spiral tank on turn insertion flame-retardant layer,
Turn stress is avoided to be lodged to side, and turn part is higher than spiral tank, the raised area can strengthen high-pressure rubber pipe
Wearability and impact resistance.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the utility model longitudinal section；
Fig. 2 is the structural representation of the utility model cross section.
Embodiment
