[0002] A flange is a part used to connect shafts to each other, and is used for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment. The flange surface has several through holes for connecting flanges.

[0003] When using flanges to connect pipelines in a piping system, one end of the flange is usually welded to the pipeline, and the two pipelines are connected through the flange. The surfaces of the two flanges are then fitted together, and bolts are used to connect the two flanges through the through holes on the flange surfaces.

[0004] However, in actual use, due to the relatively smooth surface of the flange, it is not possible to properly align the angles between the two flanges during the connection process. Furthermore, the angle between the two flanges is prone to skew during the installation of bolts, resulting in the bolts not being able to align with the mounting holes on the two flange surfaces, causing inconvenience and time consumption in the installation process.

[0026] The technical solution of this patent will be further described in detail below with reference to specific implementation methods.

[0027] like Figures 1-3 As shown, this utility model provides a technical solution: a flange with calibration and positioning function, including a disc body 1. The outer surface of the disc body 1 has several mounting holes 4. A positioning structure 2 is provided on the outer surface of the disc body 1. The positioning structure 2 includes two screws 22 with opposite thread directions on their outer surfaces. One end of each screw 22 is fixedly connected to a connecting rod 23. The end of the connecting rod 23 away from the screws 22 is fixedly connected to a round rod 25. The outer surface of the round rod 25 slides on the inner wall of the disc body 1. One end of the round rod 25 is fixedly connected to a rectangular block 26. A threaded cylinder 21 is rotatably connected to one side of the disc body 1. The upper and lower ends of the inner wall of the threaded cylinder 21 are threadedly connected to the outer surfaces of the two screws 22. Two sliding grooves 24 are provided on one side of the disc body 1, and one end of each connecting rod 23 is respectively located in one of the two sliding grooves 24. When the inner wall of plate 4 slides, by setting rectangular blocks 26, when connecting two flanges, one flange can be attached to one side of plate 1. Then, push the threaded cylinder 21 to rotate, so that the two screws 22 move in opposite directions on the inner wall of the threaded cylinder 21, causing one end of the connecting rod 23 to slide on the inner wall of the slide groove 24, so that the two round rods 25 slide on the inner wall of plate 1, so that the two rectangular blocks 26, which are far apart from each other, contact the upper and lower sides of the inner wall of the other plate 1 respectively. Then push the other plate 1 to rotate and adjust the position to align the mounting holes 4 on the surface of the two plate 1. Then push the threaded cylinder 21 to rotate, so that one side of the two rectangular blocks 26 presses against the upper and lower sides of the inner wall of plate 1 respectively, fixing the relative position and angle between the two plate 1, so as to facilitate the connection of the two plate 1 with bolts.

[0028] Specifically, such as Figures 2-4 As shown, a number of protruding strips 27 are fixedly connected to one side of the rectangular block 26. The protruding strips 27 are rubber strips. When the side of the rectangular block 26 with the rubber protruding strips 27 abuts against the inner wall of the disk 1, the position of the disk 1 is more stably restricted, and the disk 1 is less likely to slide accidentally. A diagonal rod 28 is fixedly connected to one side of the connecting rod 23. The two ends of the diagonal rod 28 are fixedly connected to one end of the connecting rod 23 respectively. By setting the diagonal rod 28, the outer surface shape of the connecting rod 23 can be reinforced, so as to avoid deformation of the connecting rod 23 after being subjected to force as much as possible, and improve the surface structure stability of the positioning structure 2.

[0029] Specifically, such as Figures 2-4 As shown, two rings 29 are fixedly connected to the inner walls of the disc 1. The rings 29 are made of rubber. The outer surface of the rod 25 slides on the inner wall of the rings 29. By setting the rubber rings 29, the contact point between the rod 25 and the inner wall of the disc 1 can be further sealed, so as to avoid leakage of fluid through the contact point between the rod 25 and the inner wall of the disc 1 when the fluid passes through the disc 1. A sleeve 210 is fixedly connected to the outer surface of the threaded cylinder 21. Several grooves are opened on the outer surface of the sleeve 210. Pressing the hand against the grooves on the outer surface of the sleeve 210 can increase the friction between the hand and the surface of the sleeve 210, making it more convenient and less likely to slip when pushing the sleeve 210 to control the rotation of the threaded cylinder 21.

[0030] Specifically, such as Figure 1 and Figure 5 As shown, a sealing structure 3 is provided on one side of the disc body 1. The sealing structure 3 includes a disc 31. An inner ring 33 is fixedly connected to one side of the disc 31, and an outer ring 34 is fixedly connected to the outer surface of the disc 31. Several through holes 32 are opened on the outer surface of the disc 31. When connecting two disc bodies 1, the disc 31 can be attached to the surface of one disc body 1, so that the outer ring 34 is stuck on the outer surface of the disc body 1 and the inner ring 33 is stuck on the inner wall of the disc body 1. The through holes 32 on the outer surface of the disc 31 are aligned with the mounting holes 4 on the outer surface of the disc body 1, and bolts are used to secure the disc 31, inner ring 34, and disc body 1. The outer ring 34 is fixed between the two discs 1. The inner ring 33 further seals the area below the contact point of the inner walls of the two discs 1, and the outer ring 34 further seals the area outside the contact point of the outer surfaces of the two discs 1, thereby improving the sealing effect when connecting the pipes through the flange. The outer ring 34 and the inner ring 33 are double-layer rings. The inner ring of the inner ring 33 and the outer ring 34 are rubber rings and the outer ring is a metal ring. By setting the outer ring 34 and the inner ring 33 to be double-layer rings with rubber rings on the inner ring and metal rings on the outer ring, the outer ring 34 and the inner ring 33 have a certain sealing performance and good outer surface strength.

[0031] The working principle of this utility model is as follows:

[0032] S1. When connecting two pipes via flanges, first weld one side of each of the two discs 1 to the pipe. Then, attach the disc 31 to the surface of one disc 1, so that the outer ring 34 is engaged with the outer surface of the disc 1 and the inner ring 33 is engaged with the inner wall of the disc 1. Align the through hole 32 on the outer surface of the disc 31 with the mounting hole 4 on the outer surface of the disc 1. Then, attach the other disc 1 to one side of the disc 31. Push the sleeve 210 on the outer surface of the first disc 1 to control the rotation of the threaded cylinder 21, causing the two screws 22 to rotate. The inner wall of the threaded cylinder 21 moves in opposite directions, causing one end of the connecting rod 23 to slide on the inner wall of the slide groove 24, so that the two round rods 25 slide on the inner wall of the disc 1 and the two rectangular blocks 26 are respectively in contact with the upper and lower sides of the inner wall of the other disc 1. Then push the other disc 1 to rotate and adjust its position to align the mounting holes 4 on the surface of the two discs 1. Then push the threaded cylinder 21 to rotate again so that one side of the two rectangular blocks 26 is respectively pressed against the upper and lower sides of the inner wall of the disc 1, thus fixing the relative position and angle between the two discs 1.

[0033] S2. Bolts are passed through several mounting holes 4 on the outer surface of the two discs 1 and through holes 32 on the outer surface of the disc 31. Nuts and bolts are used to connect the two discs 1. The inner ring 33 is used to further seal the area below the contact point of the inner walls of the two discs 1, and the outer ring 34 is used to further seal the area outside the contact point of the outer surfaces of the two discs 1.
