Gasket；The injection port for protruding into syringe 12 is provided on bottle cap.
Preferably, syringe 12 is metal needle, and with the injected gas sample into sample bottle 14, and syringe 12 can be more
It changes, is convenient to clean and repairs.
Since sample bottle 14 is negative the sky sample bottle that bears down on one, when syringe 12 protrudes into sample bottle 14, gaseous sample can
Enter in bottle under the drive of negative pressure in sample bottle 14, also, after filling sample in sample bottle 14, what sensor 21 detected
Pressure becomes positive pressure from negative pressure, and the signal is passed to controller 22, and controller 22 controls first motor 4 and rotates, to make
Sample introduction lifts 3 and syringe 14 is driven to rise, and the sampling of current sample bottle 14 can be completed.
It is provided in sample disc 13 multiple for placing the placing groove 15 of sample bottle 14 and for identifying placing groove 15
Label layer.Wherein, the quantity of placing groove 15 is at least 20, and placing groove 15 is matched with sample bottle 14.
As shown in Figure 1, placing groove 15 along sample disc 13 along the periphery equidistantly distributed of sample disc, and the equal position of placing groove 15
In far from sample disk center, gas collecting is carried out so that syringe 12 is extend into sample bottle 14.
In the present embodiment, the bottom of sample disc 13 is provided with connecting rod 5, the output end phase of connecting rod 5 and the second motor 6
Even, controller 22 is electrically connected with the second motor 6, and the second motor 6 is for rotating about the axis thereof sample disc 13.Sample disc 13 is each
The degree of central angle of the angle turned between two adjacent placing grooves 15, after the completion of acquiring current sample bottle 14, under
The injection port of one sample bottle 14 is narrowly focused towards syringe 12, so as to carry out sample acquisition incessantly.
It may also be configured to make current sample bottle 14 along the telescopic cantilever of the radial direction of sample disc 13 in addition, sample introduction lifts 3

Between distance it is identical, the injection port of next sample bottle 14 can be made to be narrowly focused towards syringe 12, that is, be carried out continuously sampling.Pass through
It is more can to make the placing groove 15 that can be arranged in sample disc 13 for above-mentioned structure, and the arrangement mode of placing groove 15 can be not limited to
Circle distribution, can be along the radial distribution of sample disc 13.
In one embodiment, shale resolution gas automatic ration sampling apparatus further includes cabinet body 7, and sample collection unit 1 is set
It is placed in the inside of cabinet body 7, air inlet 71 and gas outlet 72 are respectively arranged on the side wall of cabinet body 7.Cabinet body 7 is adopted for fixing sample
Collect unit 1, in addition, cabinet body 7 also can be replaced the structure types such as fixed frame or support.
Further, gas transfer pipeline 8 is provided between air inlet 71 and gas outlet 72, sensor 21 is arranged in gas
On transfer pipeline 8 at air inlet 71.
The specific sampling process of shale resolution gas automatic ration sampling apparatus of the invention is as follows:
The first step, air inlet 71 are connected with the outlet of shale gas solution analyzer.
Second step, when shale gas solution analyzer exhaust when, sensor 21 generate pressure signal, and by pressure signal transmission to control
Device 22 processed is carried out judging whether to reach the acquisition time being previously set by controller 22.
Firstly, if not up to acquisition time, controller 22 transmit signal to triple valve 11, make air inlet 71 and gas outlet 72
Connection, then gas is directly discharged by gas outlet 72, and without gas collecting.
Secondly, controller 22 transmits signal to triple valve 11 if reaching acquisition time, connect air inlet 71 and syringe 12
It is logical, gas is acquired.
Third step acquires gas.
Firstly, by the way that delay acquisition time is arranged in controller 22, it is residual between sensor 2 and syringe 12 to be discharged
Residual air body.
Secondly, controller 6 transmits signal to first motor 4, and first motor 4 rotates fastly, and band after delay acquisition time
Dynamic sample introduction is lifted 3 and is declined with syringe 12, until reaching at lower limit component 32, at this point, syringe 12 rapidly enters sampling bottle 14
Interior, gaseous sample is driven by the negative pressure in sampling bottle 14 to be entered in bottle.
Again, after the gas in sampling bottle 14 is adopted completely (such as 14 capacity of sampling bottle is 50mL), pressure sensor 2 can incite somebody to action
It is transferred in controller 22 by the signal that negative pressure becomes positive pressure, controller 22 controls first motor 4 and rotates, and sample introduction is driven to lift 3
It rapidly increases at upper limit component 31, syringe 12 is made quickly to withdraw from sampling bottle 14, then gas collecting process is completed.
Finally, automatically recording sample message and acquisition time by controller 22, and the rotation of the second motor 6 is controlled, thus band
Dynamic sample disc 13 turns over certain angle (such as 18 °), and next sampling bottle 14 is made to be in 12 following position directly of syringe, then,
Triple valve 11 is connected to air inlet 71 with gas outlet 72, then residual gas is discharged by gas outlet 72, automatic gas sampling process knot
Beam.
In conclusion shale resolution gas self-timing sampling apparatus can be automatically fixed in batches by the parameter setting before acquisition
Amount acquisition shale resolution gas sample, participates in without artificial, to improve shale gas parsing conventional efficient and reduce in experiment
Cost of labor.
