Examples

Referring to fig. 1 and 2, a fixed type flange root plugging device includes a base 20, a tightening rod 40, a plug 60, a supporting frame 30 and a fixing pin 50; the base 20 is used for being fixed at the root of the flange, the support frame 30 is fixedly installed on the base 20, the fixing pin 50 is rotatably connected to the support frame 30, the tightening rod 40 is sleeved in the fixing pin 50, the tightening rod 40 is in threaded connection with the fixing pin 50, and the plug 60 is fixedly installed at one end of the tightening rod 40.

When the flange root leaks, the base 20 only needs to be fixed at the flange root, for example, by fastening with a binding band or other types of fixation, then the height of the plug 60 is adjusted by rotating the tightening rod 40 so as to be attached to the flange root, and the plug 60 is attached to the position of the flange root where the leakage occurs by rotating the tightening rod 40, at this time, the tightening rod 40, the support frame 30 and the base 20 (also referred to as the flange root) form a triangular stable structure, so as to realize the plugging of the leakage position of the flange root.

The radial of fixed pin 50 is provided with the perforation, is provided with the internal thread on the fenestrate inner wall, is provided with the external screw thread with internal thread assorted on the tightening rod 40.
