Sampling hole sealing pad and sampling hole sealing method

The invention provides a sampling hole sealing pad and a sampling hole sealing method. The sampling hole sealing pad comprises a main pad and an auxiliary pad. The main pad is provided with a first through hole, the first through hole is matched with a smoke gun inserted into a sampling hole, the main pad is provided with a first opening, the first opening communicates with the first through hole,the main pad is arranged on the smoke gun through the first opening in a sleeving manner, and the first opening is closed through the auxiliary pad; and under the action of the negative pressure in aflue, the main pad is fitted to the outer tangent plane of the sampling hole to close a gap between the smoke gun and the sampling hole. According to the sampling hole sealing pad, under the action of the negative pressure in the flue, the main pad can be in close fit with the outer tangent plane of the sampling hole to achieve the sealing effect, time and labor are saved, the airtightness can beimproved, meanwhile, worke
