Problems solved by technology

Most of the existing sampling holes and sealing covers of sampling holes are fixed and sealed by threaded connection or flange connection. Corroded and difficult to open, time-consuming and labor-intensive in the opening process, not only need to consume manpower, time and bolt loosening agents, but also often use cutting tools for destructive opening, the difficulty of opening the sampling hole increases the labor intensity of the operators, delays It shortens the test time and is not conducive to the smooth progress of the test work

Abstract

The invention relates to the technical field of boiler flue sampling, and discloses a sealing device for boiler flue sampling holes, which includes a sampling hole tube and a sealing cover that is matched and connected with the sampling hole tube, and the mouth of the sampling hole tube The outer wall is provided with a plurality of protrusions arranged at intervals, and the inner wall of the sealing cover is provided with a plurality of grooves adapted to the protrusions, and the grooves are provided along the inner wall of the lower port of the sealing cover. There are a first vertical track, a second vertical track and an inclined track, and the two ends of the inclined track are respectively connected with the first vertical track and the second vertical track in a smooth transition, and between the sealing cover and the sampling hole When the tubes are sealed and connected, the protrusion moves clockwise along the first vertical track of the groove to the inclined track and finally locks on the second vertical track of the groove. The invention can normally open the sampling hole at the flue of the boiler so as to smoothly carry out the sampling work of smoke dust and flue gas.

Description

technical field [0001] The invention relates to the technical field of boiler flue sampling, in particular to a sealing device for boiler flue sampling holes. Background technique [0002] In the dust collector performance test of the power plant, the operator needs to take dust and flue gas sampling at the entrance and exit flue of the dust collector equipment. When sampling, the sampling hole at the entrance and exit flue of the dust collector equipment needs to be opened. The normal opening of the sampling hole is a key link in the test work in the test of equipment such as instruments. Most of the existing sampling holes and sealing covers of sampling holes are fixed and sealed by threaded connection or flange connection. Corroded and difficult to open, time-consuming and labor-intensive in the opening process, not only need to consume manpower, time and bolt loosening agents, but also often use cutting tools for destructive opening, the difficulty of opening the sampli...
