| titleOfInvention | Double-channel sampling device for riverway water quality monitoring system |
| abstract | The utility model discloses a two-channel sampling device for a riverway water quality monitoring system, which comprises a first sampling passage, a second sampling passage, a water pump and a sampling water tank, wherein the first sampling passage comprises a first filtering unit and a first three-way ball valve, and the first filtering unit is connected to a first port of the first three-way ball valve through a conduit; the second sampling passage comprises a second filtering unit and a second three-way ball valve, and the second filtering unit is connected to a first port of the second three-way ball valve through a conduit; an inlet of the water pump is respectively connected with second ports of the first three-way ball valve and the second three-way ball valve through a guide pipe, and an outlet of the water pump is respectively connected with third ports of the first three-way ball valve and the second three-way ball valve through guide pipes; the inlet of the sampling water tank is also connected with the outlet of the water pump. The utility model has the advantages of simple structure, use cost is low, can realize carrying out the back flush to pipe and the filter unit in first sampling route and the second sampling route automatically, can guarantee simultaneously that the water that gets into the sampling water tank can not consequently break off. |
