Step S400, negative pressure device starts to be evacuated, and the sampling liquid in container 200 to be checked enters from the liquid feeding end of inner tube 102
Enter the tube chamber of inner tube 102, then enter back into pipeline viewing mirror 105, observe the liquid level in pipeline viewing mirror 105, as sampling liquid exists
The rising of liquid level in pipeline viewing mirror 105, the second arc groove of jacking 122 of ball float 120, blocks entering for the 3rd link block 119
The import at mouth end, the liquid level for sampling liquid also just reach setting position.
Step S500, the first valve 103 and the 3rd valve 106 are closed, and negative pressure device is stopped pumping.
Step S600, the 4th valve 116 first to be opened, then slowly opens the second valve 104, sampling liquid enters sampling bottle,
When bottle to be sampled samples liquid amount in obtaining reaches institute's taken amount, the second valve 104 is closed, and opens the first valve 103, sampling
Remaining sampling liquid will be back in container 200 to be checked in device 300；
Step S700, after remaining sampling liquid is all back to container 200 to be checked in sampler 300, the 4th valve is closed
116, so as to complete whole sampling process.
In summary, enclosed sampling can be carried out using the sampler 300, liquid can be down-sampled to greatest extent
Volatilization, protection operating personnel escape injury and reduced environmental pollution.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, either which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.In addition, it will be appreciated by those of skill in the art that although some embodiments described herein include other implementations
Included some features rather than further feature in example, but the combination of the feature of different embodiments means in the present invention
Within the scope of and form different embodiments.For example, in the following claims, embodiment claimed
It is one of any mode to use in any combination.
