This pipe end has steel of axial reinforcing structure and moulds compound pipe can adapt to high -pressure occasion, can increase substantially the steel mould the ability that compound pipe bore the axial force, can avoid appearing the plastics boss take out or breaking of compound pipe end portion plastic layer is moulded to whole steel.
Description
Technical field
This utility model relates to steel-plastics composite pipe technical field, specifically refers to that a kind of pipe end is with the steel axially strengthening structure
Plastic composite.
Background technology
The net-shaped steel skeleton being made up of warp, the parallel steel wire steel-plastics composite pipe by extrusion plastic composite molding, owing to having
The characteristic that corrosion resistant is the most pressure, has obtained wide application in each row.The connected mode of steel-plastics composite pipe present stage, main
If using electric smelting connection and two kinds of forms of Flange joint.And Flange joint uses generally by steel plastic compount tube end
Injection or be wound around processing method, process at this position one when tubing works, both born tubing Flange joint axle
To power again for the Yuan Zhuhuo garden platform of pumped (conveying) medium sealing is moulded material boss.Although this connected mode is easy to use, but
Plastics boss secondary operations the most often occur up, when pressure-bearing works from steel-plastics composite pipe tube surfaces
The phenomenon extracted out.And when bearing elevated pressures due to the steel skeleton construction reason of steel-plastics composite pipe, warp steel therein
Silk does not has an effect bearing axial force, thus pipe end bear axial force excessive time moulding steel plastic compount tube end occurs
The phenomenon that the bed of material is broken, causes steel plastic compount pipeline leakage accident occur.
Notification number is CN201250961Y, entitled " a kind of can be used for heat-melting butt-joint or the steel-plastics composite pipe of Flange joint and pipe
Part " utility model patent, disclose a kind of steel-plastics composite pipe, this steel-plastics composite pipe includes plastic tube body, is located at and moulds
By the steel skeleton formed through parallel and the plastics outer lug boss being located at plastic tube body end excircle part in material pipe body, its
The also outwards bending of the end of the warp of middle steel skeleton becomes L-type.
Although the end bending using the warp of the steel-plastics composite pipe of this technology becomes L-type, but when pipe end bears axial force,
Because each warp is single dispersed structure, the L-type end of warp is easy to be straightened, so that warp loses bears axial force
Ability, still there will be above-mentioned extraction or tensile phenomenon when pressure-bearing works.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pipe end steel-plastics composite pipe with axially enhancing structure,
This pipe end adapts to high pressure occasion with the steel-plastics composite pipe axially strengthening structure, can increase considerably steel-plastics composite pipe and bear
The ability of axial force, is avoided that extracting out of plastics boss or breaking of whole steel plastic compount tube end plastic layer occur.
Technical solution of the present utility model is to provide a kind of pipe end steel-plastics composite pipe with axially enhancing structure,
Including steel plastic compount tube body, described steel plastic compount tube body includes body, warp and boss, described steel plastic compount
Tube body also includes the ring-type end plate being located in steel-plastics composite pipe body end, described warp and ring-type end plate connection.
The end of described warp becomes power transmission section through bending, leaves bending angle between described power transmission section and warp, should
Power transmission section is connected with ring-type end plate and still remains with bending angle when pressure-bearing works between power transmission section and warp, because arranging
Have the power transmission section being connected with ring-type end plate and power transmission section when pressure-bearing still and between warp, remain with bending angle, so exist
During pressure-bearing, power transmission section end just will not be straightened, and can also increase the degree that is connected firmly between warp and ring-type end plate, has
Effect avoids the situation generation deviating from ring-type end plate through thread end.
Described power transmission section outwards and is pressed in the outer end wall of ring-type end plate along the radial direction of body, prevents further and holds
During pressure, power transmission section end is straightened, and further increases the degree of being connected firmly between warp and ring-type end plate.
The end of described power transmission section is flush-mounted in ring-type end plate plate body to ring-type end plate plate body inner bending, curved through thread end
After being converted into as power transmission section, power transmission section end is again to ring-type end plate plate body inner bending, and such warp end face is final still to be moulded with steel again
The axis direction closing pipe is vertical, accordingly even when steel, mould bi-material thermal coefficient of expansion difference relatively big, when variations in temperature
The warp end face vertical with the axis direction of steel-plastics composite pipe will not produce failure by shear to the plastics of surrounding, higher bearing
During pressure, steel plastic compount tube end plastic layer will not be produced impact.
Described ring-type end plate is provided with through hole, it is simple to plastics circulation during injection, makes whole boss reach to form an entirety
Purpose.
This utility model has the advantage that the pipe end of the present utility model steel-plastics composite pipe with axially enhancing structure, logical
After crossing the ring-type end plate that setting is connected in steel plastic compount tube end with warp, make original tubing steel skeleton does not has to hold
By the warp steel wire of axial force, the axial force born during by steel-plastics composite pipe being worked with the connection of looped end plate structure
It is transformed into equably on warp by ring-type end plate, has made every warp steel wire in tubing can bear axial force, thus greatly
Improve greatly steel-plastics composite pipe and bear the ability of axial force.
