Beschreibung
Zusammenfassung:	The utility model discloses a fully-closed pressurized liquid sampling device which is connected with a liquid-sample analysis meter. The fully-closed pressurized liquid sampling device comprises a first passage and a second passage which are identical in structure. Each of the first and second passages comprises a tank, an intake and exhaust three-way magnetic valve, a sample in-out three-way magnetic valve and a sampling hand valve, and the tanks are connected to high-pressure air through the intake and exhaust three-way magnetic valves; the tanks are further connected with the liquid-sample analysis meters through the sample in-out three-way magnetic valves; one ends of the sampling hand valves are connected to the tanks and the sample in-out three-way magnetic valves while the other ends are connected to a liquid sample.
