FIELD: hydraulic engineering, possibly remote control of operation of hydraulic regulators of water level in water distribution systems. SUBSTANCE: apparatus for remote change of setting value of hydraulic regulator of water level includes electric pulse shaper, float, control valve of hydraulic regulator and mechanism for changing position of float having electric motor and reduction gear. Float is in the form of tore like body in mean part of which are arranged: electric pulse shaper and mechanism for changing position of float including in addition drum for winding rope kinematically connected with control valve of hydraulic water-level regulator. At changing setting value, electric motor operates in pulse mode control. Programmed duration of pulse is determined according to preset motion value of said rope. EFFECT: simplified design, lowered energy consumption of apparatus. 2 cl, 1 dwg |
