A natural gas hydrate formation simulation cabin pressure maintaining sampling device

Abstract

The utility model relates to hydrate sampling technical field discloses a kind of natural gas hydrate generation simulation cabin pressure maintaining sampling device, including multiple interface mechanisms being arranged on reaction kettle;Sliding cavity is provided in sampling mechanism, one end of sampling mechanism is used to be detachably connected with interface mechanism, so that sliding cavity, interface mechanism and reaction kettle inner cavity can be connected;Sampling tube is slidably arranged in sliding cavity;First valve device is arranged on sampling mechanism, controls the pass or open-circuit state of sliding cavity;Hydraulic mechanism is arranged at the end of sliding cavity away from interface mechanism, and sampling tube is driven to slide in sliding cavity by pressurization and pressure relief, realizes the insertion sampling and back operation of sampling tube to natural gas hydrate in reaction kettle, the utility model can realize pressure maintaining and fidelity coring in reaction kettle, and provide high-quality natural gas hydrate fidelity sample for subsequent test and scientific research.
