Abstract

The flange installation device and method claimed in the present invention, the flange installation device includes a first pipeline, a fixed flange, a second pipeline, a movable flange, a taper sleeve, a driving part and a bolt group; the driving part can push the top The taper sleeve acts on the nozzle of the second pipeline, so that the nozzle of the second pipeline is deformed into a bell-shaped shape; the bolt group acts on the fixed flange and the movable flange, and The bolt group can drive the movable flange to squeeze the deformed nozzle on the second pipe and move toward the direction of the fixed flange, so that the movable flange, the taper sleeve and the fixed flange Tight fit in turn. The present invention uses the physical method of extrusion deformation to realize the tight fit between the movable flange, the taper sleeve and the fixed flange, so as to realize the assembly and fixation between the first pipe and the second pipe, so that the flange installation device is suitable for It is used to transform the pipeline in the hazardous chemical area to meet the needs of the enterprise.

Description

technical field [0001] The invention belongs to the technical field related to flange installation, and in particular relates to a flange installation device and method. Background technique [0002] The connection and communication between two pipes is usually fixed by flange installation. Specifically, the flange is welded to the nozzle position of the corresponding pipe, and the two flanges are connected and fixed with bolts and nuts. However, in the hazardous chemical area, since hot fire is prohibited in the hazardous chemical area, the conventional welding method cannot be used to carry out pipeline reconstruction in the hazardous chemical area, which cannot meet the needs of enterprises. Contents of the invention [0003] Based on this, it is necessary to provide a flange installation device and method for the technical problems existing in the prior art. [0004] Specifically, a flange installation device includes a first pipe, a fixed flange fixed to the first pi...
