Abstract

The invention discloses an intermediate joint for a flexible pipeline. The intermediate joint is characterized in that the inner surfaces of outer sleeves extend from inside to outside; a plurality of ring-shaped clamping surfaces I of which the sections are distributed in a serrated manner are uniformly arranged on the inner surfaces of the outer sleeves; and a plurality of ring-shaped clamping surfaces II of which the sections are distributed in a serrated manner are uniformly arranged on the outer surfaces of the sleeve ends of inner core pipes. Accordingly, the sealing performance of the intermediate joint is greatly enhanced; meanwhile, through arrangement of a connecting part and an internal ventilation channel in the connecting part, a leaking medium can be in a circulating state and flow to the other end of the intermediate joint for being discharged; and by virtue of such structure adopted by the intermediate joint, an exhaust pipeline is protected from blockage and deformation caused by pipeline distortion or collision, the leaking medium is prevented from being accumulated, and the discharging effect is good.

Description

A kind of flexible duct transition joint
Technical field
The present invention relates to a kind of pipe joint, particularly relate 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 from bursting because revealing or permeate the pressure extremely increase of the inside hose caused, code requirement designing and arranging place system, and reveal medium and must be discharged by pipe joint internal switching.
Applying wider joint design at present, including inner core tube, trocar sheath, trocar sheath is arranged on inner core tube outside and both coaxial lines, is welded and fixed, and inner core tube outer surface and outer sleeve inner surface straightway offer profile of tooth annular groove, offer one group of steam vent at trocar sheath arc section.During use, flexible composite pipe is placed in the gap that inner core tube is formed with trocar sheath, withholds fixing by outer radial and seal flexible composite pipe.Vent structure can be affected during withholding, cause steam vent to deform, cause leakage.Use elongated steel pipe through between two steam vents, be welded to connect.The in-site installation of elongated steel pipe is highly inconvenient, and welds corrosion resistance and poor reliability, and commissure can be caused to reveal.Also have now and be directly connected to inducing QI by airway, inner core tube is divided into two sections, two sections of inner core tube two ends are connected by flange arrangement, but two ends are it may happen that rotate during the pipe joint use that flange arrangement connects, if so using airway will make airway torsional deformation, thus affect leaking medium discharge.The most existing these still have deficiency to the sealing of flexible pipeline joint.
Summary of the invention
For solving above-mentioned technical problem, the present invention devises a kind of flexible duct transition joint.
The present invention adopts the following technical scheme that

As preferably, the cross section connecting end of described inner core tube is spline surface, and transition joint two ends are respectively provided with snap-latch surface, are engaged with spline surface respectively.
Can also be that the end face connecting end of inner core tube is joint face, and the central cylindrical of joint face is protruding, and the outer ring surface of joint face is circumferentially evenly arranged with sawtooth, and transition joint two ends are respectively provided with snap-latch surface, are engaged with joint face respectively.
As preferably, a plurality of venting channels it is provided with in described connector, the most corresponding every venting channels of connector is provided with steam vent, the venting channels that corresponding steam vent connection is corresponding, is connected to airway between the steam vent of two inner core tube correspondence connectors.
As preferably, connecting of described inner core tube is provided with sealing ring on the end face at end and transition joint engaging.
Can also be that connecting of inner core tube is provided with sealing ring on the side at end and transition joint engaging.
nullCompared with prior art，The inner surface of the trocar sheath of this flexible duct transition joint extends out from inside to outside，The inner surface of trocar sheath is evenly arranged with multiple annular snap-latch surfaces that cross section is zigzag distribution，The outer surface of the sleeve end of inner core tube is evenly arranged with multiple annular snap-latch surfaces that cross section is zigzag distribution，Thus greatly strengthen the sealing of flexible duct transition joint，Certainly this caliber changing inner core tube makes the caliber difference of inner core tube，Expand in the most for convenience，Need internal diameter tube is divided into two sections engaged by transition joint，Arranging of the splined section of transition joint simultaneously and internal diameter tube joint can limit inner core tube rotation，Prevent from rotating between two sections of inner core tube causing airway torsional deformation，The setting being simultaneously connected with part and connector internal ventilation passage makes leaking medium be in circulation status，It 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，Leaking medium will not be piled up，Emission effect is good.
