The utility model discloses a thermal power plant's blowpipe target plate seat leaks vapour formula sealing device, including hindering the vapour piece and hindering the steam chest, hinder the vapour piece and be 4, hinder the steam chest and be 3, 4 are hindered vapour piece and 3 and hinder the upper and lower interval arrangement of steam chest, upper end and lower extreme and be and hinder the vapour piece, and every hinders and all is provided with 3 extraction openings on the steam chest, and the extraction opening that 3 extraction opening align to grid, 3 spares hinder on the steam chest is corresponding from top to bottom, hinder that port department circumference that vapour outdoor wall went up the lower extreme is processed into 30 degrees grooves, the port of lower extreme also is processed into 30 degrees grooves on the inner wall of vapour piece for hindering of corresponding with it, hinder the vapour piece and mate each other to weld or connect soon with the port that hinders the steam chest and be in the same place. The utility model discloses replace traditional flange formula sealing device, can freely reciprocate after both having guaranteed target plate seat the thermal expansion, reduced the steam loss of steam through the target plate again, make original manual operation change mechanical operation into, not only improved and changed the security of target plate, but also saved the plenty of time, shortened the blowpipe time, saved manpower, material resources.
