Description
Technical field
The present invention relates to a kind of pipe joint more particularly to a kind of flexible duct transition joints.
Background technology
Flexible duct is widely used in transmission corrosivity and non-aggressive medium, such as oil, gas, injection chemicals.To prevent
It bursts due to the pressure of inside hose caused by leakage or infiltration extremely increases, code requirement design exhaust system, and
Leakage medium must be discharged by pipe fitting internal switching.
Wider joint structure such as Fig. 1 is applied at present, and including inner core tube 1, outer tube 2, outer tube 2 is arranged on inner core tube 1
External and the two coaxial line, is welded and fixed, 1 outer surface of inner core tube and 2 inner surface straightway of outer tube open up tooth form annular groove, outside
2 arc section of casing opens up one group of gas vent 2-1.In use, flexible composite pipe 3 is placed in inner core tube 1 and between outer tube 2 formed
Gap withholds fixed and sealing flexible composite pipe by outer radial.Vent structure can be influenced during withholding, causes gas vent
Deformation, causes leakage.Bidirectional joint shown in Fig. 2 is the Common usage of Fig. 1 structures.Elongated steel pipe 4 is used between two gas vent 2-1
Perforation, is welded to connect.The in-site installation of elongated steel pipe is highly inconvenient, and welds corrosion resistance and poor reliability, can cause
It reveals commissure.There are also being directly connected to air guide by gas-guide tube, it is single due to during pipe fitting use both ends may send out
Raw rotation, in this way if gas-guide tube torsional deformation will be made using gas-guide tube, so as to influence leaking medium discharge.
Invention content
In order to solve the above technical problems, the present invention devises a kind of flexible duct transition joint.
The present invention adopts the following technical scheme that：
A kind of flexible duct transition joint, two outer tubes including inner core tube and socket inner core tube both ends, inner core tube appearance
Face is provided with screw thread, and inner core tube outer surface intermediate projections form boss, and connector, connector both ends point are threaded on boss
It is not fixedly connected with two outer tubes, connector inner surface is provided with venting channels, by logical in the setting ventilation of connector inner surface
Road makes leaking medium be in circulation status, flow to the discharge of the flexible duct transition joint other end, two outer sleeve inner surfaces are by interior
It extends out outward, two outer sleeve inner surfaces are evenly arranged with multiple annular snap-latch surfaces of the section for zigzag distribution.
Preferably, being provided with inner groove among the connector inner surface, venting channels cross inner groove both ends.Inner ring
The setting of slot reduces the length of venting channels, easy to process, while mitigates connector weight, and greatly reduces because foreign matter enters
Caused by venting channels block.
Preferably, the upper baffle that annular is fixedly installed in boss end positions of the inner core tube outer surface.Baffle
It is to be contacted with flexible duct steel band enhancement layer, realizes that the required circuit of cathodic protection and flexible duct are inserted into flexibility
A limiting in pipeline transition joint.
Preferably, the upper mounting groove that annular is provided at by two close end of the inner core tube outer surface, in mounting groove
It is provided with sealing ring.The structure enhances leakproofness, reduces dielectric leakage.
Preferably, the connector inner surface is provided with a plurality of venting channels, a plurality of venting channels circumferentially uniformly divide
Cloth.
Preferably, the shape both sides protrusion intermediate recess of the connector.
Compared with prior art, flexible duct transition joint setting connector is logical by being set in connector inner surface
Gas channel makes leaking medium be in circulation status, flow to the discharge of the flexible duct transition joint other end, and the structure setting makes
Exhaust passage will not be distorted or be squeezed because of pipeline and block deformation, and leaking medium will not be accumulated, and emission effect is good, while inner core
Tube outer surface is provided with screw thread, and two outer sleeve inner surfaces extend out from inside to outside, and is evenly arranged with section as zigzag distribution
Multiple annular snap-latch surfaces, the setting of the structure greatly strengthen the sealing of flexible duct transition joint both ends connection flexible duct
Property, reduce dielectric leakage.

Specific embodiment
Below by specific embodiment, and with reference to attached drawing, technical scheme of the present invention is further described specifically：
Embodiment：As shown in Figure 3, a kind of flexible duct transition joint including inner core tube 5 and is socketed inner core tube both ends
Two outer tubes 6, inner core tube outer surface are provided with screw thread, and inner core tube outer surface intermediate projections form boss, are threadedly coupled on boss
There is connector 7, connector both ends are fixedly connected respectively with two outer tubes, and connector inner surface is provided with a plurality of venting channels 10,
A plurality of venting channels are circumferentially uniformly distributed, by setting venting channels that leaking medium is made to be in circulation shape in connector inner surface
State flow to the discharge of the flexible duct transition joint other end, and two outer sleeve inner surfaces extend out from inside to outside, two outer sleeve inner surfaces
Multiple annular snap-latch surfaces of the section for zigzag distribution are evenly arranged with, inner groove 11 is provided among connector inner surface, it is more
Venting channels cross inner groove both ends, the upper baffle 8 that annular is fixedly installed in boss end positions of inner core tube outer surface,
Inner core tube outer surface is upper to be provided with annular mounting groove 9 at by two close end, and sealing ring is provided in mounting groove, connector
Shape both sides protrusion intermediate recess.
The flexible duct transition joint sets connector, by venting channels being set to make leaking medium in connector inner surface
In circulation status, it flow to the discharge of the flexible duct transition joint other end, and the structure setting makes exhaust passage will not be because of
Pipeline is distorted or is squeezed and blocks deformation, and leaking medium will not be accumulated, and emission effect is good, while inner core tube outer surface is provided with spiral shell
Line, two outer sleeve inner surfaces extend out from inside to outside, and are evenly arranged with multiple annular snap-latch surfaces of the section for zigzag distribution, should
The setting of structure greatly strengthens the leakproofness of flexible duct transition joint both ends connection flexible duct, reduces dielectric leakage.
Embodiment described above is a kind of preferable scheme of the present invention, and not the present invention is made in any form
Limitation also has other variants and remodeling under the premise of without departing from the technical solution recorded in claim.
