effect on the sample gas in the bottom cylinder 5, prevent the sample gas from leaking along with the detachment of the storage cylinder 4, and the pressure inside the storage cylinder 4 gradually increases along with the increase of the gas amount entering the storage cylinder 4, and under the action of the pressure, the inner plate 26 gradually is jacked up because the inner plate 26 is in sealing contact with the second vertical shaft 36 and the inner cylinder 25, at this time, the sample gas in the storage cylinder 4 enters the inner cylinder 25, and as the inner plate 26 continues to rise, under the connection action of the inner rod 30, the sealing plate 28 gradually rises and finally adheres to the bottom of the limiting plate 27, and the limiting plate 27 is plugged, when the sealing plate 28 is adhered to the limiting plate 27, the required sample gas is trapped in the inner cylinder 25 and the second exhaust pipe 33 is inserted into the second through hole 32, before, with the rising of the inner plate 26, the air in the inner cylinder 25 is discharged through the second exhaust pipe 33, so that the pressure balance in the inner cylinder 25 is always kept, when the sample gas needs to be sampled, by pressing the pressing ring 34, the whole second exhaust pipe 33 moves downwards and contacts with the limiting plate 40, and gradually pushes the limiting plate 40 open, the sample gas stored in the inner cylinder 25 enters into the second exhaust pipe 33 through the exhaust hole 37, because the bottom of the second exhaust pipe 33 contacts with the limiting plate 40, therefore, the sample gas can be discharged upwards only through the second exhaust pipe 33, the rapid sample discharging effect of the sample gas is realized, the inner plate 26 drives the sealing plate 28 to rise, and when the sealing plate 28 contacts with the limiting plate 27, the second sealing plate 29 can seal the exhaust head 31, at this time, the gas in the bottom cylinder 5 and the storage cylinder 4 is prevented from further entering the top of the main cylinder 1, the residual sample gas is convenient to recover and clean, the sample gas and the replacement gas entering the top of the main cylinder 1 can be discharged through the first exhaust pipe 10, and the working condition in the main cylinder 1 can be judged through the length of the first lifting plate 12 and the second lifting plate 13 along with the rising of the first lifting plate 12 and the second lifting plate 13, the working condition in the storage cylinder 4 can be judged through the length of the second marking rod 35, and the first lifting plate 12, the second lifting plate 13 and the inner plate 26 are convenient to reset.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
