Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown, the utility model is a kind of for acquiring the device of stationary source exhaust gas, including aspiration pump 1, institute
1 one end of aspiration pump connection sampling pipe 2 is stated, the other end connects sampling bottle 3, and one end of the sampling pipe 2 is provided with sealing element 4, institute
Stating sealing element 4 includes the cylindrical body 41 for being set in 2 outside of sampling pipe, and the cylindrical body 41 is connected with adsorption piece 42, described
The diameter of adsorption piece 42 is gradually increased, and one end diameter being connected with cylindrical body 41 is minimum, is additionally provided on the sampling pipe 2
Support device 5, the support device 5 include the main body 51 that can be slided in 2 outer wall of sampling pipe, are provided with support in the main body 51
Bar 52 is provided with threaded hole (not shown) in the main body 51, and a screw 53 is screwed into the threaded hole against sampling pipe 2.
When in use, sampling pipe 2 progresses into thieff hatch 9 device of the utility model, and adsorption piece 42 wraps up thieff hatch
9, main body 51 is moved to support rod 52 against adsorption piece 42, by 53 stationary body 51 of screw, at this point, thieff hatch 9 is sealed completely
It is stifled, it can be sampled.
Further, the 42 diameter maximum of adsorption piece is additionally provided with outside flanging 421.Pass through flanging 421, branch
Strut 52 is fixed on flanging 421, and sealing effect is more preferable.
Further, fluted (not shown) is set on the flanging 421, support rod 52 can be fixed in groove, close
It is more preferable to seal effect.
Further, 2 other end of sampling pipe is connected with glass sighting tube 6 and adapter tube 7 in turn.By adapter tube 7 with
Aspiration pump 1 is connected.
