Abstract
The utility model discloses an axial telescopic flange pipeline connecting assembly based on a transition sleeve, which comprises a left flange, the transition sleeve and a right flange, wherein one end of the left flange, which is far away from a flange plate, is in sealed sleeve joint with the left side of the transition sleeve, one end of the right flange, which is far away from the flange plate, is in sealed sleeve joint with the right side of the transition sleeve, and the flange plate at the end part of a pipeline, the flange plate of the left flange, the transition sleeve and the flange plate of the right flange are fixedly connected in series through bolt assemblies. The utility model provides a pipeline coupling assembling, when having guaranteed sealing reliability, improved the convenience that the pipeline was installed and removed, each accessory was changed.
Description
Technical Field
The utility model relates to the technical field of pipeline connection, in particular to an axial telescopic flange pipeline connecting assembly based on a transition sleeve.
Background
According to the difference of the sealed face form of flange, common flange has abrupt face flange (convex plane flat type), concave-convex face flange (concave-convex type flange) etc. and the tailings filling pump that present mine enterprise used, the flange that the pipeline that arranges adopted generally is abrupt face flange, and sealed corresponding adoption metal flat gasket, this kind of flange joint and sealed certain defect that exists: after pre-tightening, the gasket is easy to extend or move to two sides, the installation is easy to misplace, the sealing is easy to deviate, the gasket is only suitable for low-pressure occasions, and the high-pressure sealing is easy to leak.
If adopt current unsmooth type flange, although sealed effectual, be fit for the higher occasion of pressure, nevertheless when right flange and left flange assembly back, it can't carry out the flexible regulation of axial as required, and this convenience that has influenced both ends pipeline and has installed and removed, each accessory to a certain extent.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides an axially retractable flange pipe connection assembly based on a transition sleeve, so as to improve convenience in assembling and disassembling pipes and replacing fittings while ensuring sealing reliability.
The utility model solves the problems through the following technical means: the utility model provides an axial retractable flange pipeline coupling assembling based on transition cover, includes left flange, transition cover and right flange, the one end that its ring flange was kept away from to left side flange cup joints with the left side seal of transition cover, the one end that its ring flange was kept away from to right flange cup joints with the right side seal of transition cover, it is fixed to concatenate through bolt assembly between the ring flange of pipeline tip ring flange, left flange, transition cover and right flange.
Furthermore, the flange plate ends of the left flange and the right flange are provided with positioning rabbets.
Further, a sealing ring is arranged at the positioning seam allowance.
Furthermore, a sealing ring and an end face seal are arranged on the sealing surface of the transition sleeve and the left flange.
Furthermore, a sealing ring and an end face seal are also arranged on the sealing surface of the transition sleeve and the right flange.
Furthermore, the outer diameters of the flange plate at the end part of the pipeline, the flange plate of the left flange, the transition sleeve and the flange plate of the right flange are consistent.
The utility model has the beneficial effects that:
the utility model provides an axial retractable flange pipeline coupling assembling based on transition cover, including left flange, transition cover and right flange, the one end that its ring flange was kept away from to left side flange cup joints with the left side seal of transition cover, the one end that its ring flange was kept away from to right flange cup joints with the right side seal of transition cover, it is fixed to concatenate through bolt assembly between the ring flange of pipe end portion ring flange, left flange, transition cover and right flange. The utility model provides a pipeline coupling assembling, when having guaranteed sealing reliability, improved the convenience that the pipeline was installed and removed, each accessory was changed.
Drawings
The utility model is further described below with reference to the figures and examples.
Fig. 1 is a schematic structural view of a preferred embodiment of the present invention.
Detailed Description
The utility model will be described in detail below with reference to the accompanying drawings, as shown in fig. 1: this embodiment provides an axial retractable flange pipeline coupling assembling based on transition cover, including left flange 3, transition cover 5 and right flange 7, the left side sealed cup joint of the one end that its ring flange was kept away from to left side flange 3 and transition cover 5, the right side sealed cup joint of the one end that its ring flange was kept away from to right flange 7 and transition cover 5, be provided with sealing washer 2 and end face seal 6 on the sealed face of transition cover and left flange, also be provided with sealing washer 2 and end face seal 6 on the sealed face of transition cover 5 and right flange to improve the sealing performance of assembly between left flange 3 and transition cover 5, right flange 7 and the transition cover 5. The pipeline end flange 8, the flange of the left flange, the transition sleeve 5 and the flange of the right flange are fixedly connected in series through the bolt assembly 4, and the outer diameters of the pipeline end flange 8, the flange of the left flange, the transition sleeve 5 and the flange of the right flange are consistent.
And flange disc ends of the left flange 3 and the right flange 7 are provided with positioning rabbets 1. Left flange and right flange are connected with the pipeline that corresponds the side through the flange dish end respectively, and the location tang can improve the precision of being connected with the pipeline. Preferably, a sealing ring 2 is arranged at the positioning spigot 1 so as to improve the sealing performance of the connection with the pipeline.
To sum up, the pipeline coupling assembling of this embodiment, on the one hand, the both ends of transition cover cup joint with left flange and right flange seal respectively, have guaranteed the sealed reliability of flange butt joint, and on the other hand, the left bolt of ring flange of the bolt on ring flange right side and the ring flange of right flange that becomes flexible left flange can make left flange and right flange transition cover axial displacement relatively, has improved the convenience that the pipeline was installed and removed, each accessory was changed.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
