Description

Technical Field

[0001] The utility model belongs to the technical field of flange correction, and in particular relates to a flange correction device. Background Art

[0002] Flange is a disc-shaped part, which is most common in pipeline engineering and is mainly used for connecting pipelines. Flanges are used in pairs. Flanges are prone to misalignment during use. Misalignment means that the center lines of two adjacent flanges are not on the same horizontal plane, which will lead to failure to connect or loose connection, and then cause leakage and other safety problems. Therefore, it is necessary to use a flange correction device to correct it.

[0003] Based on the above, the inventors found that the existing flange correction device has the following shortcomings:

[0004] 1. The fixed structure is in the form of an arc surface that fits the pipe, which makes it impossible to install the device on pipes of different thicknesses. It is not convenient to add locking measures to the device to adapt to pipes of different thicknesses.

[0005] 2. During the calibration process, the calibration rod will generate rotational friction with the flange, which can easily cause damage to the flange surface. It is not convenient to add lifting measures to the device to allow the calibration rod to only move up and down. Utility Model Content
