Stucture and purpose
Used in the living and fire-fighting merged water supply system. It supplies living water at normal at normal condition and, in case ofa fire, aut-omatically close the living water and open the fire-fighting one to make it surely enough, and then when fire-fighting water stops and the pressureisreduced, resets the living water automatically. Thus making the system no need to set an individual fire -fighting water supply pipe network and bothengineering construction cost and daily water used quantity greatly saved. It features sensitive control, safety, reliability, simple debugging and long duration.
