Description
Technical field
The present invention relates to a kind of pipe flange top openings.
Background technology
The units such as metallurgy, chemical industry have a large amount of pipelines, mostly aerial to be laid with, by flanged joint between pipeline, between flange
It is sealed by gasket, since pipeline medium is varied, especially conveys the pipeline of Korrosionsmedium, be easy to be corroded rotten
It wears, it, need to be by the open-top replacement gasket of flange or stifled, pumping blind plate when replacing gasket operation and repairing pipeline operations.
At present in production, the prefabricated fixed top opening in a small amount of flange both sides, but also a large amount of flange connections do not have
Have prefabricated, due to production and many reasons such as medium, site welding top opening is unable to, so giving the open-top operation band of these flanges
Very big difficulty is carried out.Usually operation generally pries open flange using crowbar, and since the spacing pried open is less than normal, cleaning sealing surface is not very square
Just, and it is not easy to clean out, leakage phenomenon occurs after causing operation, while also very dangerous, crowbar is easy to slip, and causes to press from both sides
Hand such as falls down, collides at the injuries, and also needs to more people operation simultaneously.Long there is the time, Ren Yuanduo, intensity is big, and efficiency is low,
The drawbacks such as more than security risk.Therefore, there is an urgent need for a kind of new schemes to solve the technical problem.
Invention content
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of simple in structure, reasonable design, operations
Convenient pipe flange top opening.
To solve the above problems, the technical solution adopted in the present invention is as follows：
A kind of pipe flange top opening, including the first lantern ring and the second lantern ring that are sheathed on pipeline, the first set
It is set on the end face of ring there are two symmetrical mandril, sets that there are two symmetrical compression bar, two mandrils on the end face of the second lantern ring
It is arranged along the axial direction of pipeline with two compression bars, the compression bar is located at the side of mandril, and the end face of compression bar is right against mandril
The end face of end face, compression bar is equipped with compression spring, and thread bush is also arranged on compression bar, and the surface of mandril and compression bar is equipped with and screw thread
Cover the screw thread being connected.
Further, it is equipped with limit protrusion on the surface of the compression bar and mandril.
Further, first lantern ring and the second lantern ring are ellipsoidal structure, and on the first lantern ring and the second lantern ring
It is all provided with there are two symmetrical engaging lug, mandril is set on the engaging lug of the first lantern ring, and compression bar is set to the company of the second lantern ring
On lug.
Further, first lantern ring and the second lantern ring are welded on pipeline.
Further, the mandril is identical with the diameter of compression bar, and the diameter of compression spring is less than the diameter of compression bar.
Compared with prior art, the beneficial effects of the present invention are：After two pipelines are fixed by flanged joint, on compression bar
Compression spring will withstand on the end face of mandril, by compression bar and mandril compressed spring, then turn thread bush again, make thread bush
One end is moved on mandril, on the other end to compression bar, and compression spring is covered；When needing two flanges on pipeline separately,
First the connection bolt on flange is unloaded, thread bush is turned after allowing, one end is made to leave mandril, is acted in this way in the elastic force of compression spring
Under, thrust is formed to mandril, i.e., is pushed the pipeline residing for mandril open, makes the separation of flange quickly, safe on two pipelines, obtains
Obtain operating condition, simple in structure, reasonable design, easy operation.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is that the present invention applies the structural schematic diagram on pipeline；
Fig. 3 is the structural schematic diagram of the first lantern ring or the second lantern ring in the present invention；
In attached drawing, 1 is first pipe, and 2 be the first lantern ring, and 3 be second pipe, and 4 be the second lantern ring, and 5 be mandril, and 6 be pressure
Bar, 7 be compression spring, and 8 be thread bush, and 9 be limit protrusion, and 10 be engaging lug.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and detailed description.
Such as Fig. 1 to Fig. 3, a kind of pipe flange top opening, including the first lantern ring 2 being welded in first pipe 1 and weldering
The second lantern ring 4 being connected on second pipe 3, first pipe 1 are connected with second pipe 3 by respective flange, the first lantern ring position
In the side of the flange in first pipe, the second lantern ring is located at the side of the flange on second pipe.The end of first lantern ring 2
It is set on face there are two symmetrical mandril 5, sets that there are two symmetrical compression bar 6, two 5 Hes of mandril on the end face of the second lantern ring 4
Two compression bars 6 are arranged along the axial direction of pipeline, and the compression bar 6 is located at the side of mandril 5, and the end face of compression bar 6 is right against mandril 5
End face, the end face of compression bar 6 is equipped with compression spring 7, and mandril 5 is identical with the diameter of compression bar 6, and the diameter of compression spring 7 is less than the straight of compression bar 6
Diameter is convenient for compression press spring in this way.And thread bush 8 is also arranged on compression bar 6, the surface of mandril 5 and compression bar 6 is equipped with and thread bush
8 screw threads being connected.Limit protrusion 9 is equipped on the surface of compression bar 6 and mandril 5, limit protrusion carries out thread bush effective
Ground limits.
In order to ensure that the fastness of structure, the first lantern ring 2 and the second lantern ring 4 are ellipsoidal structure, two such lantern ring
At least the height at both ends is less than the height of flange, consequently facilitating two flanges of connection, and on the first lantern ring 2 and the second lantern ring 4
It is all provided with there are two symmetrical engaging lug 10, mandril 5 is set on the engaging lug 10 of the first lantern ring 2, and compression bar 6 is set to second set
On the engaging lug 10 of ring 4.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make various other
Corresponding change and deformation, and all these changes and deformation should all belong to the protection domain of the claims in the present invention
Within.
