Further, first, second blind hole is set on respective ring flange in uniform intervals, and each blind hole is adjacent to its
Two bolt connecting holes centre-to-centre spacing it is equal.
Further, the pillar top is hemispherical, equal rounding at the end face edge of the insertion end of each duct section
Angle.
Further, the notch edges of the annular groove of each flange side surface upper supply tube road section insertion are rounded down.
Further, the notch edges of the groove are to there is fillet.
Further, the screw tip face of the push rod bolt is hemisphere face.
Beneficial effects of the present invention：The present invention sets dismountable ring flange to realize fast quick-mounting in the connection end of duct section
Tear open, coordinate elastic sealing gasket using the elastic force of cylindrical spring to realize the release of the expansive force of pipeline, prevent crack, booster.
First the pillar of duct section end is axially promoted along pipeline when using, in squeezing action lower supporting rod retraction duct wall, respective tube
Road section is just inserted into inside flange side surface, and pillar is simultaneously headed into groove in ring flange (i.e. in ring flange by cylindrical spring release
Pillar patchhole) in, pillar is blocked, so as to duct section and ring flange be coupled together；Push rod bolt is twisted in dismounting
Enter in screwed hole, so as to corresponding supporting post top is back in the tube wall of duct section, while duct section and ring flange are pulled open,
It is convenient to mount and dismount, can also bears certain axial expansion power, it is to avoid crack, booster.
Quick-disassembly structure of the invention is combined with the dilatancy structure that various springs are constituted, and can be easy to change junction at any time
Various springs or the relative flimsiness component such as elastic sealing gasket, this is more passed through for maintenance even scraps whole segment pipe
Ji is practical.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the end view of ring flange.
Fig. 3 is zoomed-in view at I in Fig. 1.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages of the invention and effect easily.
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Fig. 1-3, a kind of quick change swelling pipeline attachment structure, including duct section 1 and located at the two ends of duct section 1
First flange disk 2, be provided between the every two neighboring bolt connecting hole on the first flange disk 2 one it is coaxial with duct section 1
The first blind hole 3, the aperture of first blind hole 3 towards the outside of the duct section 1, is all provided with each first blind hole 3 respectively
There are a cylindrical spring 4, the cylindrical spring 4 to be can be inserted at second flange side surface afterwards outside stretching out first blind hole 3
In second blind hole 5, similarly, second blind hole 5 is arranged between adjacent two bolt connecting hole of second flange disk, and described
Two ring flanges are arranged in another duct section (not shown) being connected with the duct section 1, and first, second ring flange is used
Attachment bolt through the bolt connecting hole is connected, and be provided with elastic sealing gasket between two flange side surfaces (does not show in figure
Go out), the elastic sealing gasket has certain elastic shrinkage amount, you can be deformed, and can be made of elastic caoutchouc, its knot
Structure is identical with the gasket structure of general pipe flange connection, and some through holes are provided with above, and the through hole herein is used for institute
State cylindrical spring 4 and attachment bolt is passed through, after two segment pipes section is connected, the cylindrical spring 4 is in compressive state, and this is engraved
State elastic sealing gasket to be also extruded, so as to seal；When pipeline axial expansion, the above-mentioned cylindrical spring 4 in junction is entered one
Step extruding is shunk, and elastic sealing gasket is also further extruded the contact friction force of contraction, increase and flange side surface, sealing
Property also strengthened, be should be noted when actual fabrication is used select cylindrical spring 4 elasticity (stiffness factor), have as far as possible
There is suitable amount of contraction, it is excessive without regard to amount of contraction and make elastic sealing gasket by conquassation, for elastic sealing gasket,
Cylindrical spring 4 also needs to play certain axial expansion overload protective function, it is ensured that sealing.Certainly, in some cases, manage
The sealing requirements in road are not very high even without sealing requirements, are only intended to the extensive transmission of medium or discharge, this
When, then the negligible consideration for sealing.
Each duct section inserts connection, the tube wall appearance at the insertion end of each duct section from the end face of its connected ring flange
Face offers some evenly spaced small blind holes, the small blind hole rounded array centered on the center of circle of corresponding duct section,
The small blind hole bottom is fixedly connected with the bottom of small column spring 6, the fixing phase of pillar 7 of the top of small column spring 6 and circle
Even.After ring flange is inserted into place, small column spring 6 will be recessed in the jacking of the pillar 7 to corresponding ring flange for duct section
Blocked in groove, and the pillar 7 does not all skid off the small blind hole, so as to by the use of pillar 7 as connecting pin by duct section and method
Blue disk is coupled together.One is additionally provided with the extraneous screwed hole 8 being connected in the bottom hole of each small blind hole, and push rod bolt 9 can be twisted
Enter in the small blind hole in screwed hole 8 and where the pillar 7 is pushed up back into it, and simultaneously pull out corresponding pipeline section from ring flange
Go out, realize fast quick-detach.
Further, as shown in Fig. 2 first, second blind hole is set on respective ring flange in uniform intervals, each is blind
The centre-to-centre spacing of hole to its two adjacent bolt connecting hole is equal, cylindrical spring 4 is carried more uniform, it is ensured that attachment structure is whole
The stability of body, prevent elastic seal ring because of unbalance stress seepage.
Further, as shown in figure 3, the top of the pillar 7 is hemispherical, the end face of the insertion end of each duct section
Edge is rounded down 10, so that the insertion end of pillar 7 and each duct section is smoothly inserted.
Further, as shown in figure 3, the notch edges of the annular groove of the insertion of each flange side surface upper supply tube road section 1 fall to have
Fillet 11, to coordinate with the fillet at above-mentioned insertion end end face edge, improves the insertion speed of duct section.
Further, as shown in figure 3, the patchhole (groove i.e. on ring flange) of the pillar 7 on the ring flange
Orifice edge to there is fillet 12, so that the hemispherical with 7 top coordinates, smoothly slide into and out, improve assembly and disassembly efficiency.
Further, on the basis of the top of above-mentioned pillar 7 is hemispherical, the screw tip face of the push rod bolt is half
Sphere, preferably to dismantle the connection between pipeline and ring flange, prevents duct section from being interfered when pulling out.
