[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0025] Please refer to the attached Figure 1 To the attached Figure 5 The utility model is described as a rotary flange structure.

[0026] Existing valve products typically feature integrally cast flanges and valve bodies. However, during installation, the flange screw holes often misalign with the pipe, making installation impossible. This requires re-cutting the welded flange, adjusting the angle, and re-welding. This labor-intensive and time-consuming process significantly reduces installation efficiency and significantly prolongs the construction cycle, hindering project completion on schedule and within specified requirements.

[0027] Therefore, this rotating flange structure includes multiple flange blocks 11, and multiple flange blocks 11 can be assembled into flange plates 1. Multiple flange blocks 11 are provided with connecting components 2. After the multiple flange blocks 11 are assembled into flange plates 1, they are connected and fixed through the connecting component 2. The flange plates 1 can be sleeved onto the valve body 4. The flange plates 1 can be rotated relative to the valve body 4 to be installed with the flange to be docked. This flange structure is installed on the valve body 4 as a separate component for use, so that the flange plates 1 can rotate freely relative to the valve body 4. When the valve is installed on the pipeline during construction, even if the flanges welded to the pipeline (that is, the flanges to be docked) are misaligned and not concentric, the flange plates 1 can be rotated to make the flange holes of the flange plates 1 coincide with the flange holes of the flanges to be docked, and then fixed by bolts, which will not affect the installation connection between the valve body 4 and the pipeline.

[0028] The multiple flange blocks 11 are all identical. Preferably, the specific number of the flange blocks 11 is two, and the two flange blocks 11 are convenient for assembly into the flange plate 1. In other embodiments of the present invention, the specific number of the flange blocks 11 can also be other numbers. As long as there are no less than two flange blocks 11, the flange plate 1 can be sleeved onto the valve body 4.

[0029] The second surface 112 and the third surface refer to the two end surfaces of the flange 1 , and the first surface 111 may refer to any one of the four side surfaces of the flange 1 .

[0030] The flange 1 is sleeved onto the annular groove 41 of the valve body 4 to limit the radial and axial position of the flange 1. By sleeved onto the annular groove 41, the second surface 112 of the flange 1 contacts the side surface of the annular groove 41, and the center of the flange 1 contacts the bottom surface of the annular groove 41, so that the flange 1 cannot move radially and axially. The flange 1 can only rotate with the valve body 4 as the center. Specifically, when the flange 1 is sleeved onto the annular groove 41 of the valve body 4, the flange 1 and the annular groove 41 of the valve body 4 are on the same axis.

[0031] Multiple flange blocks 11 are assembled into a flange 1 on the annular groove 41 of the valve body 4. When installing the flange 1 on the valve body 4, multiple flange blocks 11 need to be assembled into a flange 1 on the annular groove 41 of the valve body 4 so that the flange 1 is connected to the valve body 4.

[0032] After multiple flange blocks 11 are assembled into a flange plate 1, the connections of adjacent flange blocks 11 are connected and fixed by a connecting assembly 2; specifically, the connecting assembly 2 includes an insert 21, and screw holes 3 are provided on the insert 21 and the flange block 11. After the screw holes 3 of the insert 21 coincide with the screw holes 3 of the adjacent flange block 11, the screws 22 are screwed into the screw holes 3 to connect and fix the adjacent flange blocks 11. In other embodiments of the utility model, through holes may also be provided on the insert 21, and screw holes 3 are only provided on the flange block 11, so that after the through holes of the insert 21 coincide with the screw holes 3 of the adjacent flange block 11, the screws 22 are passed through the through holes, and then the screws 22 are screwed into the screw holes 3 of the flange block 11 to connect and fix the adjacent flange blocks 11, as long as the connection and fixation of the adjacent flange blocks 11 can be guaranteed.

[0033] Regarding the first embodiment of the insert 21, the insert 21 includes a first limit block 211 and a second limit block 212. The insert 21 is "L"-shaped, and the first limit block 211 is vertically fixedly connected to the second limit block 212. The first limit block 211 and the second limit block 212 are both provided with screw holes 3. The screw holes 3 of the first limit block 211 coincide with the screw holes 3 of the first surface 111 of the flange block 11, and the screw holes 3 of the second limit block 212 coincide with the screw holes 3 of the second surface 112 of the flange block 11, so that the insert 21 is respectively connected and fixed to the two surfaces of the flange block 11, thereby being able to resist tension to a greater extent.

[0034] Regarding the second embodiment of the insert block 21, the insert block 21 includes a first limiting block 211 or a second limiting block 212. The insert block 21 is in a "one" shape and is only fixedly connected to one surface of the flange block 11. That is, when the insert block 21 is the first limiting block 211, the insert block 21 is only fixedly connected to the first surface 111 of the flange block 11. When the insert block 21 is the second limiting block 212, the insert block 21 is only fixedly connected to the second surface 112 of the flange block 11. As long as the connection strength between the flange blocks 11 can be ensured.

[0035] Regarding the third embodiment of the insert block 21, the insert block 21 includes a first limiting block 211, a second limiting block 212 and a third limiting block. The third limiting block is perpendicularly and fixedly connected to the end of the first limiting block 211 far from the second limiting block 212, making the insert block 21 in a "冖" shape. The insert block 21 is fixedly connected to three surfaces of the flange block 11. The first limiting block 211 is fixedly connected to the first surface 111 of the flange block 11, the second limiting block 212 is fixedly connected to the second surface 112 of the flange block 11, and the third limiting block is fixedly connected to the third surface of the flange block 11, so that the insert block 21 is fixedly connected to three surfaces of the flange block 11 respectively, further improving the tensile resistance (not shown in the figure).

[0036] Preferably, the length of the second limiting block 212 is longer than the length of the first limiting block 211, so that the screw holes 3 on the second limiting block 212 and the screw holes 3 on the first limiting block 211 are not on the same straight line and are staggered, which not only avoids interference but also improves the tensile resistance. In other embodiments of the present utility model, the length of the second limiting block 212 can also be shorter than the length of the first limiting block | 211, or the length of the second limiting block 212 can be the same as the length of the first limiting block 211.

[0037] A limiting groove 12 is provided on the flange 1. The insert block 21 can be inserted into the limiting groove 12. By providing the limiting groove 12, after multiple flange blocks 11 are assembled into the flange | 1, the insert block 21 is inserted into the limiting groove 12, so that the insert block 21 is limited by the limiting groove 12, and after the insert block 21 is inserted into the limiting groove 12, the screw holes 3 of the insert block 21 automatically coincide with the screw holes 3 of the flange block 11. Specifically, an opening groove is provided on the flange block 11, and the screw holes 3 on the flange block 11 are provided in the opening groove. After multiple flange blocks 11 are assembled into the flange 1, the opening grooves at the joints of adjacent flange blocks 11 are connected to form a limiting groove 12, so that the insert block 2 | 1 connects and fixes two adjacent flange blocks 11.

[0038] When the insert block 21 includes a first limiting block 211 and a second limiting block 212, the limiting groove 12 includes a first connecting groove 121 and a second connecting groove 122. The limiting groove 12 is in an "L" shape, the first connecting groove 121 and the second connecting groove 122 are vertically connected, and screw holes 3 are provided on both the first connecting groove 121 and the second connecting groove 122. The screw hole 3 of the first limiting block 211 coincides with the screw hole 3 of the first connecting groove 121, and the screw hole 3 of the second limiting block 212 coincides with the screw hole 3 of the second connecting groove 122.

[0039] When the insert block 21 includes the first limiting block 211 or the second limiting block 212, the limiting groove 12 includes the first connecting groove 121 or the second connecting groove 122. The limiting groove 12 is in a "one" shape, and screw holes 3 are provided on both the first connecting groove 121 or the second connecting groove 122. When the insert block 21 is the first limiting block 211, the screw hole 3 of the insert block 21 coincides with the screw hole 3 of the first connecting groove 121. When the insert block 21 is the second limiting block 212, the screw hole 3 of the second limiting block 212 coincides with the screw hole 3 of the second connecting groove 122.

[0040] When the insert block 21 includes a first limiting block 211, a second limiting block 212 and a third limiting block, the limiting groove 12 includes a first connecting groove 121, a second connecting groove 122 and a third connecting groove. The limiting groove 12 is in a "冖" shape, the third connecting groove is vertically connected to one end of the first connecting groove 121 far from the second connecting groove 122. Screw holes 3 are provided on the first connecting groove 121, the second connecting groove 122 and the third connecting groove. The screw hole 3 of the first limiting block 211 coincides with the screw hole 3 of the first connecting groove 121, the screw hole 3 of the second limiting block 212 coincides with the screw hole 3 of the second connecting groove 122, and the screw hole 3 of the third limiting block coincides with the screw hole 3 of the third connecting groove (not shown in the figure).

[0041] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here.
