Description

Technical Field

[0001] The invention belongs to the technical field of grinding, and particularly relates to a flange sealing surface grinding device. Background Art

[0002] Due to the good comprehensive performance of the flange, it is widely used in the pipeline connections of basic engineering such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, hygiene, water heating, fire protection, electric power, aerospace, shipbuilding, etc. As is well known, a large part of the pipeline connection quality depends on the quality of the connecting flange. Especially for pipelines with high requirements for laying tightness, such as high-temperature sealing flanges, if there are scratches on the end face, it will lead to poor sealing. Affected by the pressure inside the pipeline, it is easy to deform, cause pipeline leakage or inaccurate pressure value monitoring, affecting safe operation.

[0003] However, during the handling, construction or daily use of the flange, it is inevitable to have slight collisions and frictions, resulting in scratches or cracks. If the flange sealing surface cannot be ground in time to ensure the flatness of the sealing surface, the leakage will rapidly expand under the scouring of the medium, causing huge losses; if it is a leakage of toxic, harmful, flammable or explosive medium, it may also cause major safety accidents. Therefore, the quality of the flange sealing surface is particularly important; and the existing flange processing and grinding equipment can only grind one side of the flange during one grinding process. After one side is processed, it is necessary to change the surface and grind it again. The whole grinding process takes a long time and has low processing efficiency, affecting the progress of the project construction.
