Description
Technical Field
The utility model relates to a flange detects technical field, especially relates to a flange flatness detection device.
Background
The glass lining reaction pot belongs to the reaction equipment of first and second kind pressure vessels, the flange connection is composed of a pair of flanges, a gasket and several bolts and nuts. The flanges are sealed by a gasket, the gasket is placed between the sealing surfaces of the two flanges, after the nut is screwed down, the specific pressure on the surface of the gasket is deformed after reaching a certain value, and the uneven parts on the sealing surfaces are filled up, so that the connection is tight and leakless. However, when the rigidity of the flange is insufficient, or the flatness error of the sealing surface of the flange exceeds a certain range due to the deformation of the flange caused by the influence of external force, the sealing is not tight, and the glass lining glaze layer on the surface of the flange is cracked due to the excessive and powerful tightening of the clamp.
The equipment which is installed in place on site is generally difficult to carry out flange flatness detection on line, but before glass lining glaze slurry is sprayed on the flange, the detection on the sealing surface of the flange is necessary, so that the online flange flatness detection device is necessary.
