Description

Technical Field

[0001] The utility model relates to a novel flange. Background Art

[0002] A flange is a connecting element commonly used in piping systems. It is usually a circular metal disk with several mounting holes around it, which is used to connect to other flanges or equipment through bolts. The design of the flange enables it to withstand a certain amount of pressure and ensure the sealing of the connection. Existing flanges are usually welded to the end of the pipe when in use. However, during the welding process, the mounting holes on the flange are close to the weld, and welding slag splashes can easily enter the mounting holes and cause blockage, affecting the subsequent bolt installation. Therefore, it is necessary to develop a new type of flange to solve the above problems. Utility Model Content

[0003] The purpose of the present invention is to provide a new flange to solve the problems raised in the above background technology.

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] A new type of flange includes a flange plate, which is provided with a flange cylinder. The flange plate and the flange cylinder are an integral structure. An adjustment cylinder is rotatably provided on the side wall of the flange cylinder. The adjustment cylinder is provided with multiple protective plates. The bottom of the protective plate is provided with a through groove. The lower side of each protective plate is provided with a mounting hole, and the mounting hole is provided on the flange plate. A magnet block is provided on one side of each protective plate, and one end of the protective plate is in contact with the magnet block.

[0006] Preferably, an annular groove is provided on the side wall of the flange cylinder, and the inner wall of the adjustment cylinder is in contact with the annular groove.

[0007] Preferably, the adjusting cylinder and the protective plate are an integral structure, and both the adjusting cylinder and the protective plate are made of carbon steel.

[0008] Preferably, a plurality of the protective plates are arranged in a ring shape at equal intervals on the adjustment cylinder.

[0009] Preferably, the flange plate and the flange cylinder are provided with through holes with the same diameter.

[0010] The beneficial effects of the utility model are as follows: the utility model can use the protective plate to cover the mounting hole. When welding the flange, the protective plate can block the splashing of welding slag during welding, avoid the mounting hole from being blocked, and prevent the subsequent bolt installation from being affected; when the flanges on the two pipes are docked, the adjusting cylinder is rotated to make the protective plate rotate accordingly, so that the protective plate and the mounting hole are staggered, which can avoid the protective plate hindering the installation of the bolt, and the operation is simple and convenient.

[0017] See Figures 1 to 4 A new type of flange shown includes a flange plate 11, on which a flange cylinder 12 is provided. The flange plate 11 and the flange cylinder 12 are an integral structure. An adjusting cylinder 14 is rotatably provided on the side wall of the flange cylinder 12, and a plurality of protective plates 15 are provided on the adjusting cylinder 14. The bottom of the protective plate 15 is provided with a through groove 16, and the lower side of each of the protective plates 15 is provided with a mounting hole 13, which is provided on the flange plate 11. A magnet block 18 is provided on one side of each of the protective plates 15, and one end of the protective plate 15 is fitted with the magnet block 18; when welding the flange, the protective plate 15 blocks the mounting hole 13, thereby preventing welding slag from splashing during welding and preventing the mounting hole 13 from being blocked. The magnet block 18 magnetically absorbs the protective plate 15, so that the protective plate 15 can stably cover the mounting hole 13 and will not be arbitrarily offset in position.

[0018] Furthermore, an annular groove 17 is provided on the side wall of the flange cylinder 12, and the inner wall of the adjustment cylinder 14 is in contact with the annular groove 17; the annular groove 17 limits the adjustment cylinder 14 so that the adjustment cylinder 14 can only rotate around the flange cylinder 12 and will not detach from the flange cylinder 12.

[0019] Furthermore, the regulating cylinder 14 and the protective plate 15 are an integral structure, and both the regulating cylinder 14 and the protective plate 15 are made of carbon steel.

[0020] Furthermore, a plurality of the protective plates 15 are arranged on the adjustment cylinder 14 in a ring-shaped manner and at equal intervals.

[0021] Furthermore, the flange 11 and the flange cylinder 12 are provided with through holes of the same diameter; the through holes on the flange 11 and the flange cylinder 12 are connected into a whole, and the pipes can be inserted into the through holes on the flange 11 and the flange cylinder 12 during installation.

[0022] The working principle of the present invention is that when welding the flange, the protective plate 15 is located on the upper side of the mounting hole 13 to block the mounting hole 13. The magnet block 18 attracts the protective plate 15 through magnetic force, so that the protective plate 15 can stably cover the mounting hole 13, thereby using the protective plate 15 to block the welding slag splashing during welding and avoid the mounting hole 13 from being blocked. When the flange on the mounting pipe is docked with the flange on another pipe, the mounting holes 13 on the two flanges are aligned, and then the adjusting cylinder 14 is rotated to make the protective plate 15 rotate accordingly, so that the protective plate 15 is staggered with the mounting hole 13, and the protective plate 15 no longer blocks the mounting hole 13. Then, the bolts are passed through the mounting holes 13 and the nuts are tightened to complete the docking of the two flanges.

[0023] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
