Technical Field
The utility model relates to the technical field of measurement and detection tools, in particular to a flange sealing surface flatness detection device.
Background
In daily work, the flange connection consists of a pair of flanges, a gasket and a plurality of bolts and nuts. The flanges are sealed by gaskets, the gaskets are placed between the sealing surfaces of the two flanges, the nuts are screwed, and at the moment, the specific pressure on the surfaces of the gaskets is deformed after reaching a certain numerical value and fills up uneven positions on the sealing surfaces, so that tight connection is realized. 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 aim of sealing cannot be achieved no matter how the bolt is fastened. Therefore, it is necessary to perform flatness inspection of the sealing surface of the flange before flange installation.
