Layering runoff sampling system

The utility model relates to a layering runoff sampling system of runoff sampling system, especially a synchronization, high efficiency, easy accuse belongs to hydrology technical field. Layering runoff sampling system mainly includes negative pressure extended tubular, water sample receiving flask, vacuum pump and air compressor machine. Negative pressure extended tubular can link to each other with a plurality of water sample receiving flasks by the transparent plastic pipe through having the valve. Set up two holes in the negative pressure extended tubular upper right side and link to eachother with a vacuum pump and an air compressor machine respectively, set up a valve on the plastic tubing respectively. The utility model provides a synchronous, high -efficient, the easy layering runoff sampling system of controlling can acquire high -quality water sample for researcher in hydrological experiment research, play positive promoting effect to the development of hydrology and hydrological experiment research
