Ordinary pressure pipe -line system liquid reagent device of maring

The utility model discloses an ordinary pressure pipe -line system liquid reagent device of maring belongs to pipe -line system equipment field. Ordinary pressure pipe -line system liquid reagent device of maring is including filling subassembly and bypass subassembly, and in ordinary pressure pipe -line system's daily use, first isolating valve and second isolating valve in the filling subassembly are in the closed condition, and the diverter valve in the bypass subassembly is in the open mode, and the medium in the pipeline can be through the circulation of second pipeline, when needing injected liquid body reagent in ordinary pressure pipe -line system, operating personnel is earlier to injecting an amount of liquid reagent into in the filling funnel, opens first isolating valve and second isolating valve on the first pipeline in the filling subassembly again to close the diverter valve in the bypass subassembly, under the impetus of the medium in the pipeline, the liquid reagent ofinjection enters into or
