Embodiment Construction

[0025] like figure 1 As shown, the sampling hole bracket plug used for pollution source smoke monitoring of the present invention is made of high temperature resistant rubber material as a whole, including an airbag part and a bracket inflation device, and the airbag part includes a front airbag 1 and a rear airbag 3, and a front airbag 1 and a rear airbag 3 are connected by the connecting part 2, the outer diameter of the connecting part 2 is smaller than the outer diameters of the front airbag 1 and the rear airbag 3. The sides of the front airbag 1 and the rear airbag 3 in contact with the sampling hole 11 are all in the shape of a truncated cone, so as to fit the sampling hole and fill the gap between the sampling hole and the sampling gun rod. Inside the front airbag 1 , the connecting portion 2 and the rear airbag 3 are provided with a through inner hole 8 . The front airbag 1, the connecting portion 2 and the rear airbag 3 are provided with a connected air cavity 4, an...

Abstract

The invention discloses a sampling hole support plug used for pollution source smoke monitoring. The sampling hole support plug comprises an air bag part and a support inflating device. The air bag part comprises a front air bag and a rear air bag, the front air bag and the rear air bag are connected through a connection part, an inner through hole is formed inside the front air bag, the connection part and the rear air bag, a connected air cavity is formed inside the front air bag, the connection part and the rear air bag, the rear air bag is provided with an inflation port and an exhausting plug, and the inflation port is connected to the support inflating device through a connection pipe. A gun barrel of a sampling gun is arranged inside the inner hole in a sleeved mode, the front air bag penetrates through a sampling hole and extends into an exhausting cylinder, the rear air bag is located at the outer end of the sampling hole, or the front air bag directly abuts against the outer end of the sampling hole, an inflation pump is started for inflating the air cavity, the front air bag and the rear air bag are expanded, and therefore the gap between the sampling gun and the sampling hole is completely sealed. The sampling hole support plug has the advantages that the structure is simple, the operation is convenient, the application range is wide, air leakage is prevented, and the accuracy of monitoring data is guaranteed.

Description

technical field [0001] The invention relates to a device for sealing a sampling hole installed on a smoke sampling gun of a pollution source and belongs to the technical field of sampling hole sealing. Background technique [0002] When carrying out environmental monitoring on the exhaust pipe of the pollution source, it is necessary to insert the sampling gun into the monitoring hole. Due to the large gap between the gun body and the monitoring hole, air leakage is prone to occur, which affects the accuracy of the monitoring data. In addition, during the sampling period, the sampling gun needs to be held by the sampling personnel for a long time, which causes personnel fatigue and affects work efficiency. [0003] Chinese patent document CN105276596A discloses "A Sealing Device for Boiler Flue Sampling Hole", which includes a sampling hole tube and a sealing cover that is connected with the sampling hole tube, and the outer wall of the sampling hole tube is provided with A...
