Description

Technical Field

[0001] The utility model relates to the technical field of glasses valve maintenance, in particular to a glasses valve maintenance device. Background Art

[0002] In the blast furnace ironmaking process, glasses valves are mostly used in gas pipelines.

Therefore, for glasses valves that have failed, they can be restored to use after replacing the expansion joints. When repairing glasses valves, after the expansion joints are removed, the flange holes on the new expansion joints and the flange holes on one side of the valve cannot confirm the deviation angle, resulting in the valve flange holes being inconsistent with the flange holes on the pipeline when the valve is installed online after the repair is completed.
