description The utility model relates to the technical field of sampling devices, and discloses a hand-operated plunger valve sampling device which comprises a sampling device body, and the sampling device body is provided with a medium channel for a sampling medium to circulate and a liquid outlet which is communicated with the medium channel in a crossed manner; the plunger valve rod is matched with the medium channel in a sliding mode so as to open or close the liquid outlet, and in the scheme, the plunger valve rod and/or the medium channel are/is arranged in the mode that when the plunger valve rod slides in the direction of opening the liquid outlet, the plunger valve rod can slide in the direction of opening the liquid outlet; a sampling medium in the medium channel can start to flow out to the liquid outlet before the free end of the plunger valve rod reaches the liquid outlet, so that before the sampling medium reaches the liquid outlet, the flowing-out sectional area of the sampling medium is small, the flow sp
