Description

Flange clamping device

Technical Field

The invention relates to the technical field of flange auxiliary tools, in particular to a flange clamping device.

Background

The flange, also called flange or flange, is a part for interconnecting the shaft and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment.

Need when connecting the flange closely lean on together with two sets of flanges with being convenient for connect earlier, and when artificially drawing close two sets of flanges probably because the weight of flange and rather than the pipeline or the axle of being connected is overweight, and thereby it influences subsequent connection and use to lead to drawing close inseparably, and need press from both sides tight flange equally behind the bolt corrosion of flange, current clamping device who is used for the flange adopts two sets of clamping screw to press from both sides the flange in one side of flange, then probably cause the flange to shift to the opposite side in the in-process of pressing from both sides tightly, the phenomenon of flange dislocation and then lead to in the pipeline transmission thing to reveal equally probably appears.
