Description
Technical field：
The utility model is relevant with connecting pipe, especially relevant with flexible composite high pressure pipeline connecting pipe.
Background technology：
It is mutual using a small seam between inner core and outer barrel in the flexible composite high pressure pipeline connecting pipe used in the past
Positioning, connection is insecure, reduces the ability of axial tension in pipe fitting resistance pipeline use, causes tubing easily from inner core and outer barrel
Between slip, and using outer barrel attaching type mode compressing pipe end tube wall, inner core is constant, thus reduces the interior logical straight of pipeline
Footpath, directly affects the conveying capacity of pipeline, when particularly conveying some solid particulate matters.
Utility model content：
The purpose of this utility model is to overcome the above insufficient, there is provided a kind of outer barrel has equal anti-axial direction with inner core
The ability of pulling force, it is connected firmly, reliable flexible composite high pressure pipeline connecting pipe.
The purpose of this utility model is achieved like this：
The utility model flexible composite high pressure pipeline connecting pipe, can outwards it be expanded under swollen mould extruding including having one
The inner core with anti-skidding retaining annular groove of flexible composite high pressure pipeline end tube wall is compressed, is carried in an interior annular anti-skidding
The outer barrel of retaining annular groove, outer barrel small end face turn into an overall structure, this reality with the big end outer circumference surface of inner core by being welded to connect
Turn into an overall structure by being welded to connect with the outer barrel and inner core of novel flexible composite high pressure conveyer pipe connecting pipe, outer barrel with
Inner core has an ability of equal anti-axial tension, can outwards expand compression flexible composite high pressure under swollen mould extruding including inner core
Conveying tube end tube wall so that internal diameter of the pipeline is identical with inner core internal diameter, and the conveying capacity of pipeline is unaffected, is connected firmly, can
Lean on.
Above-mentioned flexible composite high pressure pipeline connecting pipe, the big end head of inner core are welded with a ring flange, connection
Pipe fitting can be interconnected by ring flange.
Above-mentioned flexible composite high pressure pipeline connecting pipe, the big end head of inner core are threaded structure or positioning boss,
Connecting pipe can be interconnected by nut.
There are one layer of phosphorating treatment layer, surface phosphorus in above-mentioned flexible composite high pressure pipeline connecting pipe, connecting pipe surface
Change process layer and not only play antisepsis, and play antifriction lubrication when extruding inner core with interior swollen mould and act on.
Above-mentioned flexible composite high pressure pipeline connecting pipe, there is at least one passage in outer barrel small end position, filling
Manage and extrude outlet when inner core outwards expands compression flexible composite high pressure pipeline end tube wall with interior swollen mould and use.
The outer barrel of the utility model flexible composite high pressure pipeline connecting pipe is whole as one by being welded to connect with inner core
Body structure, outer barrel and inner core have an ability of equal anti-axial tension, and swollen mould extruding is lower including inner core can outside turgor pressure
Tight flexible composite high pressure pipeline end tube wall so that internal diameter of the pipeline is identical with inner core internal diameter, and the conveying capacity of pipeline is not by shadow
Ring, be connected firmly, reliably.

Embodiment：
Embodiment 1：
Fig. 1~Fig. 3 gives the figure of the present embodiment 1.Referring to Fig. 1, Fig. 2, Fig. 3, sequence number 1 is inner core, and 2 be outer barrel, and 3 be outer barrel
Anti-skidding retaining annular groove in interior annular, 4 be anti-skidding retaining annular groove on inner core periphery, and 5 be that outer barrel is welded to connect into inner core
The welding position of structure is integral, 6 be ring flange, and 7 be passage, and 17 be connecting pipe surface granosealing layer, and 8 be flexible
Composite high pressure conveyer pipe, 9 be enhancing silk material such as steel wire, glass etc. in delivery pipe, and 10 be interior swollen mould, and 11 be fixed plate work
Tool, 12 be pull bar, and 13 be oil cylinder.The utility model steel modeling flexible composite high pressure pipeline connecting pipe so works, first
Outer barrel and inner core are welded to connect as an overall structure, are installed on fixed plate instrument 11, using the pulling force of oil cylinder 13,
Outwards expansion compresses the end tube wall of flexible composite high pressure pipeline 8 to inner core 1 under the extruding of swollen mould 10 inside, forms flexible compound
High-pressure delivery pipe connected pipe fitting.The outer barrel of the utility model flexible composite high pressure pipeline connecting pipe passes through the company of welding with inner core
It is connected into and is integral structure, outer barrel and inner core has an ability of equal anti-axial tension, the swollen lower energy of mould extruding including inner core
Outwards expansion compresses flexible composite high pressure pipeline end tube wall so that internal diameter of the pipeline is identical with inner core internal diameter, the conveying of pipeline
Ability is unaffected, is connected firmly, reliably.(the utility model connecting pipe also can use outer barrel compression attaching type mode with it is soft
Property composite high pressure conveyer pipe connection).
Embodiment 2：
Fig. 4~Fig. 6 is the figure of embodiment 2.This implementation is substantially same as Example 1, and it is in the big end head band of inner core not exist together
There is helicitic texture 14 (referring to Fig. 4), another big end head of inner core carries positioning boss 15 and nut 16 (referring to Fig. 5), connecting tube
Part can interconnect (referring to Fig. 6) by nut.
The various embodiments described above are that the above of the present utility model is further described, but this should not be interpreted as to this
The scope of the above-mentioned theme of utility model is only limitted to above-described embodiment.It is all that this practicality is belonged to based on the technology that the above is realized
New scope.
