| titleOfInvention | Active pressure maintaining in-situ seawater sampler with liquid extraction style and its sampling method |
| abstract | The invention discloses an in-situ seawater sampler with an active pressure-maintaining pattern for liquid extraction, comprising: a sampler body, an isolation piston is arranged in the sampler body, and the isolation piston divides the internal space of the sampler body into a sampling chamber and a non-sampling chamber The sampling chamber has a sampling inlet and a drain outlet; an active pressure control system, which is connected to the sampler body, the active pressure control system includes a pressure detection part, a controller and a regulating device, and the pressure detection part detects the pressure in the sampling chamber, When the pressure in the sampling chamber is lower than the preset value, the controller controls the regulating device to charge or extract the liquid medium into the non-sampling chamber, so as to maintain the pressure in the sampling chamber unchanged. In addition, the present invention also discloses a seawater sampling method, which adopts the above-mentioned active pressure-maintaining in-situ seawater sampler for sampling. The active pressure-maintaining in-situ seawater sampler of the pumping style can realize active pressure-maintaining of the in-situ seawater to be sampled, and has high pressure-maintaining precision and good safety performance. |
