The air inlet fixed disc is provided with the diameter round concave station more slightly larger than outlet rotating circular disk diameter on one side, and circle is recessed Platform bottom is along the circumferential direction evenly arranged with multiple air admission holes, and is separately connected air inlet short tube, and air inlet short tube is perpendicular into gas-solid Fixed disk is simultaneously stretched out from air inlet fixed disc another side;Air inlet pipe position mark is indicated at air inlet fixed disc edge.
On one face of the outlet rotating circular disk, a semi-circular gas collection groove, outlet are provided with along the circumferencial direction of disc On another face of rotating circular disk, it is equipped with analyzer air inlet short tube and aspiration pump air inlet short tube;Aspiration pump air inlet short tube connection half Annular gas collection groove, it is vertical with outlet rotating circular disk, and stretched out from another face of outlet rotating circular disk.
The air inlet hole site of the air inlet fixed disc is overlapped with the semi-circular gas collection groove on outlet rotating circular disk, air inlet Short tube connects semi-circular gas collection groove by air admission hole.
The torsional spring axis is welded and fixed with outlet rotating circular disk, and outlet rotating circular disk is tightly pressed against into gas-solid by spring On fixed disk.
When the utility model is used, the fixed disc air inlet short tube that multichannel is sampled to air induction hose and the present apparatus connects, will Gas analysis instrument air induction hose is connected with the analytical instrument air inlet pipe of outlet rotating circular disk, is evacuated pump steam inlet and aspiration pump phase Even, it after gas sampled analysis all the way, is switched to clockwise or counterclockwise by the knob on outlet rotating circular disk In another way air inlet pipe, Analysis On Gaseous Constituentss are carried out successively;And the other pipelines not being connected with analytical instrument then pass through aspiration pump Lasting pumping, keeps gas constantly to extract out, carries out analysis measurement at any time, to be easily switched on different pipelines, saving is set The time for depositing gas in entire sampling line is changed, the switching between each gas piping can in real time, be flexibly carried out.
The utility model has the beneficial effects that the utility model is simple in structure, practical reliable, operation flexibly, is adapted to not With the free switching between quantity sampling line, the time of flue section exhaust gas components measurement can be saved, it is ensured that the real-time of measurement, It improves work efficiency.The utility model is suitable for the sampling and measuring of industrial enterprise's exhaust gas components.
