Mouth 10, then after the injection port 64 on sampler barrel drive end bearing bracket 59, into titanium foil sampling bag 62, since the pressure inside and outside bag is put down
Weighing apparatus, much larger than the nitrogen pressure in inflator 73, pressure differential promotes lives the seawater pressure between sampler barrel 60 and titanium foil sampling bag 62
To left movement, nitrogen is compressed plug 83, so that pressure increases, is sampled and is stopped when pressure balance.The sampling timing of setting terminates
Afterwards, sampling valve is closed.At this time, the piston 83 in inflator 73 is in dynamic equilibrium state, maintains in sampler barrel 60 and inflator 73
Pressure balance.When shifting sample, high pressure liquid chromatography is pumped into connection air admission hole 87, and turns on pressurize valve rod 76, is then turned on sampling
Valve, hydrothermal solution are flowed out from probe tube 5, realize the isobaric transfer of sample.
Since titanium foil sampling bag 62 welds together with wedge block, wedge block links together with sampler barrel 60, and samples
Cylinder 60 is titanium alloy material, can be by inside and outside high pressure, and 62 internal pressure of titanium foil sampling bag and 60 internal pressure of sampler barrel are equal, so
It is also highly pressurised liquid in titanium foil sampling bag 62；Meanwhile added an osculum on welding assembly, by the opening for controlling discharge outlet
With closing so that titanium foil sampling bag 62 can fill 45MPa highly pressurised liquids in the sampler 2.
Cleaning process before sampling can screw off sampler barrel drive end bearing bracket 59 from sampler barrel 60, by diaphragm seat briquetting 22 from
Screwed off on driver connection seat 25, they and the parts that link together together be placed in high temperature furnace calcination for a period of time,
Remove organic matter therein.
During secondary sample, without using motor valve opening, but pin 26 is removed, unscrew driver connection seat 25 and diaphragm seat pressure
Screw thread between block 22, can control sample transfer rate by unscrewing the opening and closing degree of extent control valve.
The pressurize organic matter sampler structure is simple, is sampled using deep sea hydraulic；Need to be by metal sampler using preceding
450 DEG C of heating a period of times of valve and titanium foil sampling bag are the cleanable surface contacted with sample, simple thorough；In sampler with sample
Organic matter component is not present in the surface of product contact, realizes no pollution；The sampler can realize the pressurize and isobaric transfer to sample,
And there is air-tightness；Sampling rate is limited to improve the purity of sample by throttle orifice during sampling, secondary sample speed is adjustable；This hair
The maximum depth selection of bright pressurize organic matter sampler is up to 4500m, and heatproof is up to more than 450 DEG C.
The foregoing is merely the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment party
Formula, every technical solution for belonging to the principle of the invention belong to protection scope of the present invention.For those skilled in the art
