Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawing:
A kind of storage tank automatic airtight sampler is adopted as shown in Figure 1, including several samples connecting with tank 1 to be sampled
Sampling point position is provided with triplate line control valve 14,14 One In and Two Out of triplate line control valve, the input of triplate line control valve 14
End is connect with sample, and at the convergence of output end one one and convergent point 16 is connected with sampler；Sample in the present embodiment
There are three settings, including sample 1, sample 2 12 and sample 3 13.
Sampler includes threeway valve group, and sampling bottle 2 is connected in threeway valve group, be provided on sampling bottle 2 fuel inlet fitting and
Exhaust joint.Fuel inlet fitting and exhaust joint are double self-closing connectors.
Threeway valve group includes the inlet valve 18 and exhaust valve for being triple valve, 18 Two In and One Out of inlet valve, the company of oil inlet one
Convergent point 16 is connect, oil outlet connects fuel inlet fitting；Exhaust valve two goes out one into air inlet connects exhaust joint, and gas outlet one connects
There are adsorption tanks 191, gas outlet two connects oil inlet two.
The output end two of triplate line control valve 14 is cascaded and is connected with process displacement valve 15, and process replaces valve 15
Convergent point 16 is connected, convergent point 16 is connected with air driven pump 17, and air driven pump 17 is connected to tank 1 to be sampled.Band is free on air driven pump 17
Gas control valve 171 starts air driven pump 17 using compressed air.
Linkage 181 is provided in threeway valve group, when linkage 181 gets to sample bits, the oil outlet of inlet valve 18
It is connected to oil inlet one, the air inlet and air outlet one of exhaust valve are connected to；When linkage 181 gets to emptying position, inlet valve 18
Oil outlet be connected to oil inlet two, the air inlet gas outlet two of exhaust valve is connected to.Particularly, when 181 row of getting to of linkage
When vacancy, circulation loop is formed between inlet valve 18- exhaust valve-sampling bottle 2, the sample oil in inlet valve 18 and pipeline is in gravity
Flowed under effect into sampling bottle 2, pressure becomes larger in sampling bottle 2, by the air in the pipeline between sampling bottle 2 and exhaust valve to
It is promoted in inlet valve 18, these air moved into inlet valve 18, it can pipeline between auxiliary propulsion inlet valve 18 and sampling bottle 2
