Description
Technical field
The utility model relates to a kind of high-voltage flexible pipe fitting, and specifically, the utility model relates to a kind of metallic hose, particularly a kind of metallic hose carrying ultrahigh pressure.
Background technique
In some visual plants of industry such as Aero-Space, petrochemical industry and marine oil and gas probing, need configuration can flexible pipe that is high pressure resistant, that can normally work in extreme temperature conditions again, particularly working pressure is higher than 10MPa, the flexible pipe of medium temperature-196 DEG C ~ 200 DEG C.The metal hose wall made under prior art condition is thin, flexible, although can resistance to extreme temperature, can not bear ultrahigh pressure.The flexible pipe adopting quality of rubber materials or organic synthesis material to make, can bear high pressure under normal temperature condition, but then voltage endurance capability straight line decline in extreme temperature conditions.At present, also have the precedent using metal universal joint to substitute extreme pressure hose in engineering, the program solves a difficult problem for high pressure resistant and resistance to extreme temperature well.Although universal joint can break-in, can not substitute flexible pipe completely, it is flexible not enough for there is maximum problem, and radial displacement very flexible, without the ability of carrying axial tension, can not meet the compensation demand of corollary equipment.Generally speaking, flexible pipe or the gimbal structure of prior art manufacture are unreasonable, and function is comprehensive not, can not meet engineering actual demand.
Model utility content
The utility model, mainly for prior art Problems existing, proposes a kind of ultrahigh pressure metallic hose of external strengthened layer, and this flexible pipe strengthening structure is simple, extreme temperature reliably, is not feared in sealing, voltage endurance capability is strong, flexible foot, and compensating movement is flexible.
The utility model is achieved through the following technical solutions technical goal.
The ultrahigh pressure metallic hose of external strengthened layer, it comprises flange, adapter, bellows, steel wire, metal net cover and sheath.The described bellows two ends mouth of pipe is sequentially tightly connected respectively and takes over and flange, forms the metallic hose that can be used for outer connection.Its improvements are: described adapter is circle straight tube, and adapter stage casing outer wall is provided with circular groove.Until flat crest in described steel wire winding to every trough of bellows, the axial set metal net of all crests along bellows, this layer of metal net cover is arranged alternately at least 1 layer of steel wire and 1 layer of metal net cover again, the circumferential strengthened layer of steel wire composition to bellows that order is wound around, the axial strengthened layer of metal net cover composition to bellows of overcoat, metal net cover two ends and the steel cord end be between double layer of metal net, unified extend to adapter outer wall place, stage casing, collect with sheath and tighten rear unification and fix and connect.
As further improvement project, the circular groove axial cross section on the outer wall of described adapter stage casing is zigzag fashion, and Angle of hook is 30
0~ 40
0, the unified oblique flange side of sawtooth.
As further improvement project, described wire quality is flange side stainless steel, diameter 0.3 ~ 3.0mm.
As further improvement project, in the trough of bellows, winding steel wire diameter is 0.2 ~ 1.5mm, and outside the crest of bellows, winding steel wire diameter is 1.5 ~ 3mm.
As further improvement project, described metal net cover material is Stainless Steel Wire braiding, is the fabric that a kind of longitudinal direction tiltedly knits structure.
The utility model compared with prior art, has following good effect:
1, on the trough and crest of bellows, set up strengthened layer, structure is simple, easily realizes industrialization;
2, can determine the number of plies of setting up strengthened layer on the trough and crest of bellows according to bearing pressure size, under the protection of multilayer strengthened layer, the bearing capacity multiplication of thin-wall corrugated tube, easily reaches design objective;
3, be in the circumferential strengthened layer on bellows outer wall and axial strengthened layer, all form with thin diameter wire layout, there is certain flexibility, make supporting bellows still have good flexibility, meet ducts and compensate requirement;
4, bellows and the strengthened layer metal material manufacture of setting up, product structure intensity is high, stable performance, both ability ultrahigh pressure, also can work in extreme temperature conditions.

Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Embodiment 1
The ultrahigh pressure metal hose examples of external strengthened layer shown in Fig. 1, supporting in liquefied ammonia transmission pipeline, bore is 150mm, bearing pressure 25MPa, transmission medium temperature-196 DEG C.The ultrahigh pressure metallic hose of described external strengthened layer, it comprises flange 1, adapter 2, bellows 3, steel wire 4, metal net cover 5 and sheath 6.The described bellows 3 two ends mouth of pipe is tightly connected an adapter 2 respectively, to be tightly connected flange 1, to form a kind of common metal flexible pipe at the free end of adapter 2.Described adapter 2 is circle straight tube, and adapter 2 stage casing is provided with circular groove, and the object offering circular groove is the chimeric of strengthened steel wire 4 and metal net cover 5, is interconnected intensity and meets to improve the requirement carrying high pressure.Circular groove axial cross section in the present embodiment is zigzag fashion, and Angle of hook is 30
0, unified oblique flange 1 side of sawtooth.Described steel wire 4 is coiling silk, and be wound into successively in every trough of bellows 3 till flat crest, because consider requirement for anticorrosion, steel wire 4 used herein adopts material to be SUS304 stainless steel, diameter 0.3mm.Then along the axial set metal net 5 of all crests of bellows 3.The present embodiment, because of carrying ultrahigh pressure, does not only still reach strengthening expection by above-mentioned strengthening structure, treats on this layer of metal net cover 5, be arranged alternately two layers of steel wire 4 and two layers of metal net cover 5 again, namely by being wound around layer of steel wire 4 enclosure layer of metal net 5 again.Steel wire 4 material of rear winding is SUS304 stainless steel equally, but diameter is thicker than the steel wire 4 be wrapped in trough, and the present embodiment selects the steel wire 4 of diameter 1.5mm.The steel wire 4 of the utility model layered windings in bellows 3 trough and on metal net cover 5, is formed the circumferential strengthening structure of bellows 3.The metal net cover 5 of layering suit weaves with SUS304 Stainless Steel Wire, and this fabric is a kind of longitudinally oblique braided fabric with resistance to tension, the several layers of metal net cover 5 axial strengthened layer of suit formation to bellows 3 jointly.Jointly be connected with metal net cover 5 end of suit with the steel wire 4 of follow-up winding to realize bellows 3, by metal net cover 5 two ends and steel wire 4 end that is between double layer of metal net 5, unified extend to outer wall place, adapter 2 stage casing, then collect with sheath 6 and tighten rear unification and fix and connect.Connected by integration, the thin-wall corrugated tube 3 being in internal layer is fully strengthened, to reach the requirement of carrying ultrahigh pressure.Although the bellows in the utility model 3 is among strengthened layer, but own flexibility is not subject to too many loss, the metal net cover 5 external because of it and the steel wire 4 be wound around form strengthened layer and remain flexible structure, so bellows 3 still has enough plastic deformation abilities to meet compensation of pipeline requirement.In addition, the bellows 3 in the utility model and the strengthened layer set up all adopt metal material manufacture, and product structure intensity is high, stable performance, both ability ultrahigh pressure, also low-temperature-resistant, can certainly stablize use under worst hot case.
