[0004] The above method can realize the replacement of two large flanges. However, it is cumbersome to disassemble all the bolts and nuts on the two large flanges during the process; The large flange is warped, and it is difficult to control the distance between the two large flanges after it is warped. It is easy to make the two large flanges form a state where one end is large and the other end is small, which is not convenient for the replacement of the sealing gasket; When the two large flanges after lifting are lowered and the sealing gasket is pressed, it is difficult to control the speed at which the two large flanges close together, so that the sealing gasket part is damaged by the compression of the two large flanges first, so that Poor sealing between two large flanges after replacement

Abstract
The invention discloses a flange gap adjustment device and method. The flange gap adjustment device comprises a long screw, a first blocking piece and a second blocking piece; a first thread structureand a second thread structure which have opposite thread directions are arranged on two sides of the long screw, a first adjusting sleeve is screwed on the first thread structure on the long screw, and a second adjusting sleeve is screwed to the second thread structure; and a first pushing surface is arranged on one side, facing the second adjusting sleeve, of the first adjusting sleeve, the first blocking piece is attached to the first pushing surface, a second pushing surface is arranged on one side, facing the first adjusting sleeve, of the second adjusting sleeve, the second blocking piece is attached to the second pushing surface, and the first blocking piece and the second blocking piece are staggered. When applied to gap adjustment of a first large flange and a second large flange,the flange gap adjustment device is convenient to operate, and the adjusted sizes are controllable, so that the first large flange and the second large flange can be stably and uniformly spread.
Description
technical field [0001] The invention belongs to the technical field related to large-scale flange clearance adjustment, and in particular relates to a flange clearance adjustment device and method. Background technique [0002] Large flanges refer to flanges that exceed the dimensions specified by the relevant state departments. Two large flanges are connected by 36, 56 or even more bolts and nuts, and there are usually sealing gaskets between the two large flanges to seal the two large flanges. , where the opposite faces of the two large flanges are each formed with a boss for pressing the sealing gasket. [0003] At present, when replacing the sealing gaskets placed in the two large flanges, it is usually necessary to disassemble all the bolts and nuts on the two large flanges, and then multiple workers use pry bars to remove the two large flanges. The flange is pried open, and then the replacement sealing gasket is put into the position between the two large flanges, an...
