Description
Technical field
This utility model relates to a kind of pipe joint, particularly relates to a kind of flexible duct transition joint.
Background technology
Flexible duct is widely used in transmission corrosivity and non-aggressive medium, such as oil, gas, injection chemicals.For preventing
Burst because revealing or permeate the pressure extremely increase of the inside hose caused, code requirement designing and arranging place system, and
Reveal medium to be discharged by pipe joint internal switching.
Applying wider joint design such as Fig. 1 at present, including inner core tube 1, trocar sheath 2, trocar sheath 2 is arranged on inner core tube 1
Outside and both coaxial lines, be welded and fixed, and inner core tube 1 outer surface and trocar sheath 2 inner surface straightway offer profile of tooth annular groove, outside
Sleeve pipe 2 arc section offers one group of steam vent 2-1.During use, flexible composite pipe 3 is placed in inner core tube 1 and between trocar sheath 2 formed
Gap, withholds fixing by outer radial and seals flexible composite pipe.Vent structure can be affected during withholding, cause steam vent
Deformation, causes leakage.Bidirectional joint shown in Fig. 2 is the Common usage of Fig. 1 structure.Elongated steel pipe 4 is used between two steam vent 2-1
Through, it is welded to connect.The in-site installation of elongated steel pipe is highly inconvenient, and welds corrosion resistance and poor reliability, can cause
Commissure is revealed.Also having now and be directly connected to inducing QI by airway, during list uses due to pipe joint, two ends may be sent out
Raw rotation, if so using airway will make airway torsional deformation, thus affects leaking medium discharge.
Utility model content
For solving above-mentioned technical problem, this utility model devises a kind of flexible duct transition joint.
This utility model adopts the following technical scheme that
A kind of flexible duct transition joint, including inner core tube and two trocar sheaths at socket inner core tube two ends, inner core tube appearance
Face is provided with screw thread, and inner core tube outer surface intermediate projections forms boss, and threaded on boss have connector, and connector two ends are divided
Not fixing with two trocar sheaths and be connected, connector inner surface is provided with venting channels, and two outer sleeve inner surface extend out from inside to outside, and two
Outer sleeve inner surface is evenly arranged with multiple annular snap-latch surfaces that cross section is zigzag distribution.
As preferably, being provided with inner groove in the middle of described connector inner surface, venting channels crosses inner groove two ends.Internal ring
The setting of groove decreases the length of venting channels, it is simple to processing, alleviates joint weight simultaneously, and greatly reduces because foreign body enters
The venting channels blocking caused.
As preferably, described inner core tube outer surface is positioned at boss end positions and is fixedly installed the baffle plate of annular.Baffle plate
It is to contact with flexible duct steel band enhancement Layer, it is achieved the loop required for cathodic protection, is also that flexible duct inserts flexibility
One in pipeline transition joint spacing.
As preferably, described inner core tube outer surface is located close at two ends be provided with the mounting groove of annular, in mounting groove
It is provided with sealing ring.This structure strengthens sealing, reduces dielectric leakage.
As preferably, described connector inner surface is provided with a plurality of venting channels, and a plurality of venting channels the most uniformly divides
Cloth.
As preferably, the shape both sides projection intermediate recess of described connector.
Compared with prior art, this flexible duct transition joint arranges connector, by arranging logical at connector inner surface
Gas passage makes leaking medium be in circulation status, flow to the discharge of the flexible duct transition joint other end, and this structure arranges and makes
Exhaust passage will not block deformation because of pipeline distortion or extruding, and leaking medium will not be piled up, and emission effect is good, simultaneously inner core
Tube outer surface is provided with screw thread, and two outer sleeve inner surface extend out from inside to outside, and be evenly arranged with cross section be zigzag distribution
Multiple annular snap-latch surfaces, the setting of this structure greatly strengthen these flexible duct transition joint two ends and connects the sealing of flexible duct
Property, reduce dielectric leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of Traditional flexible pipe joint；
Fig. 2 is the structural representation of Traditional flexible pipeline bidirectional joint；
Fig. 3 is a kind of structural representation of the present utility model；
In figure: 1, inner core tube, 2, trocar sheath, 2-1, steam vent, 3, flexible composite pipe, 4, steel pipe, 5, inner core tube, 6, overcoat

Detailed description of the invention
Below by specific embodiment, and combine accompanying drawing, make further specifically to retouch to the technical solution of the utility model
State:
Embodiment: as shown in Figure 3, a kind of flexible duct transition joint, including inner core tube 5 and socket inner core tube two ends
Two trocar sheaths 6, inner core tube outer surface is provided with screw thread, and inner core tube outer surface intermediate projections forms boss, threaded on boss
Having connector 7, connector two ends are fixing with two trocar sheaths respectively to be connected, and connector inner surface is provided with a plurality of venting channels 10,
A plurality of venting channels is circumferentially uniformly distributed, and two outer sleeve inner surface extend out from inside to outside, and two outer sleeve inner surface are uniformly arranged
The multiple annular snap-latch surfaces having cross section to be zigzag distribution, are provided with inner groove, a plurality of venting channels in the middle of connector inner surface
Cross inner groove two ends, inner core tube outer surface is positioned at boss end positions and is fixedly installed the baffle plate 8 of annular, inner core tube appearance
Being located close at two ends be provided with the mounting groove 9 of annular on face, be provided with sealing ring in mounting groove, the shape both sides of connector are convex
Play intermediate recess.
This flexible duct transition joint arranges connector, makes leaking medium by arranging venting channels at connector inner surface
It is in circulation status, flow to the discharge of the flexible duct transition joint other end, and this structure arranges and makes the exhaust passage will not be because of
Pipeline distorts or extrudes and block deformation, and leaking medium will not be piled up, and emission effect is good, and inner core tube outer surface is provided with spiral shell simultaneously
Stricture of vagina, two outer sleeve inner surface extend out from inside to outside, and are evenly arranged with multiple annular snap-latch surfaces that cross section is zigzag distribution, should
The setting of structure greatly strengthen these flexible duct transition joint two ends and connects the sealing of flexible duct, reduces dielectric leakage.
