By using above-mentioned technical proposal, by being provided with the first bulge loop and second that circumferentially direction extends on outer ring
The medial surface of bulge loop, the first bulge loop and the second bulge loop can be connected with the lateral surface in flange joint tongue face, and then serve and can paste
Close in the outside in flange joint tongue face, because flange joint tongue face and the axle center of flange are coaxial, be achieved that the first bulge loop and the
Also it can realize coaxial with flange axle center after the laminating of two bulge loops, then be wound pad and installed, can be achieved with high-precision
Centering, and height of the height no more than flange joint tongue face of the first bulge loop and the second bulge loop, can guarantee that spirotallic gasket two
Sealing property between individual flange.
As the further improvement of the present invention, the upper end of first bulge loop and the second bulge loop is additionally provided with flexible guiding
Ring.
By using above-mentioned technical proposal, flexible guiding ring is provided with, flexible guiding ring is served among installation process
Bottom surface that can be in the form of strutting and outside the flange joint tongue face of flange fits, and is not only only capable of realizing the first bulge loop, second convex
Ring and the compactness of flange connection, serve preposition sealed effect, realize the double-deck close of flexible guiding ring and spirotallic gasket
Envelope.
As the further improvement of the present invention, the both side surface of the locating ring is coaxially arranged with annular groove, described
First bulge loop and the second bulge loop are by being fixedly welded in annular groove.
By using above-mentioned technical proposal, the setting of annular groove, the adaptation in different flange joint tongue faces can be realized by serving,
The alignment of installation site can be realized according to various sizes of flange tenon face (i.e. different flange types).
As the further improvement of the present invention, first bulge loop and the second bulge loop are fixed by welding in annular groove
Interior, the edge mouthful of the annular groove is provided with annular solder groove.
By using above-mentioned technical proposal, welding can guarantee that fixed firm intensity, further be provided with annular solder
Groove, can guarantee that welding medium can make the first bulge loop, the second bulge loop with positioning ring surface without many at annular solder groove
Remaining welding medium, it is ensured that the sealing of junction.
As the further improvement of the present invention, the inner surface of first bulge loop and the second bulge loop is equiped with magnet
Piece.
As the further improvement of the present invention, flat thin magnet is equiped with the inner surface of the flexible guiding ring.
By using above-mentioned technical proposal, flange is generally magnet, therefore is equiped with magnet in the inner surface of flexible guiding ring
Piece, and flat thin magnet is also equiped with the inner surface of the first bulge loop and the second bulge loop, the flat thin magnet of installing can be played and flange
Mutually adsorb, coordinate even closer.
As the further improvement of the present invention, the flat thin magnet is embedded in the first bulge loop, the second bulge loop and flexible guiding
It is no more than in the medial surface of ring and highly the surface of medial surface.
By using above-mentioned technical proposal, by being provided with flat thin magnet, and flat thin magnet is no more than the first bulge loop, second convex
The surface of ring and flexible guiding ring medial surface, can play effect of more preferably fitting.
In summary, the invention has the advantages that：
1st, the setting of the first bulge loop and the second bulge loop, serves the flange joint tongue face that can fit in, so ensure spirotallic gasket with
The precision for the centering that flange is installed；
2nd, by the setting of flexible guiding ring, the flange joint tongue face of different height that can be adapted to, and flexible guiding ring are served
Serve preposition sealing function；
3rd, the setting of annular groove, the adaptation in different flange joint tongue faces can be realized by serving, can be according to various sizes of flange
The alignment of installation site is realized in tenon face (i.e. different flange types), and the setting of groove can be played and more preferably fitted
Effect.
