PURPOSE: An automatic electric control system of a water gate using a float is provided to open and close the water gate rapidly with electricity when a water level reaches a peak. CONSTITUTION: An automatic electric control system of a water gate using a float comprises a redirection check valve(20), a power unit assembly(30), a low-water level signal valve(40) and an electric conversion valve(50). The redirection check valve is connected to a water gate cylinder(2) with a reciprocating fluid line(21). The power unit assembly has a hydraulic tank(33) and a hydraulic pump. The low-water level signal valve is installed in the bottom part of a guide pipe(12). The low-water level signal valve delivers the working pressure to the electric conversion valve through for a signal fluid line(41). |
