Referring to fig. 1-5, the operation principle of the counter balance flange 200 is as follows:
the counter balance flange 200 includes an upper flange unit 210, a lower flange unit 220, and a backing ring 230. The plurality of top stiffening plates 212 of the upper flange single body 210 and the plurality of guide stiffening plates 222 of the lower flange single body 220 are spaced from each other to form a stiffening plate gap 201, the backing ring 230 is assembled in the stiffening plate gap 201 and abuts against the side surfaces of the plurality of top stiffening plates 212 and the side surfaces of the plurality of guide stiffening plates 222 forming the stiffening plate gap 201, that is, the plurality of top stiffening plates 212 are indirectly connected with the plurality of guide stiffening plates 222 through the backing ring 230, and after the upper flange single body 210 is connected with the lower flange single body 220, the backing ring 230 is assembled in the stiffening plate gap 201, so that the backing ring 230 can maintain the relative position in the stiffening plate gap 201 under the abutting action of the plurality of top stiffening plates 212 and the plurality of guide stiffening plates 222.
Compared with the connection mode of welding the bearing ring with the jacking stiffening plate 212 and the guide stiffening plate 222 in the prior art, the connection mode can reduce the structure of the reverse balance flange 200 and improve the overall economy of the reverse balance flange 200; secondly, the backing ring 230 can maintain the relative position in the gap 201 of the stiffening plates under the abutting action of the plurality of abutting stiffening plates 212 and the plurality of guiding stiffening plates 222, so that the welding surface in the reverse balance flange 200 can be effectively reduced, and further the structural defects caused by welding seams can be reduced.
In addition, referring to fig. 4 and 5, in the prior art, when the reverse balance flange 200 is installed, due to the fact that the top fastening stiffening plate 212 is in direct contact with the guide stiffening plate 222, a misalignment problem when the top fastening stiffening plate 212 is in butt joint with the guide stiffening plate 222 is easily caused by a processing error or a small deformation in a transportation process, the area of an actual balance contact surface is smaller than a design value, the stress condition of the balance contact surface is deteriorated, and the field construction progress is also influenced.

That is, when the body 231 of the grommet 230 is disposed, the body is assembled by the branches 233, so as to facilitate the installation and transportation of the grommet 230. In other embodiments of the present invention, the body 231 of the backing ring 230 may be integrally formed into a closed ring shape.
Further, when the body 231 includes the plurality of segments 233, in order to improve the installation stability of the grommet 230, a plurality of top fastening stiffener plates 212 or guide stiffener plates 222 are spaced between two adjacent ear plates 232.
