The utility model discloses an use water tower water level automatic regulating apparatus of concentrated multiplying power as core, include: concentrated magnification adjustment ware gc3, main regulator gc1, secondary controller gc2, drainage flow transmitter rd, the concentrated magnification adjustment ware gc4 of level four, water level [measuring] transmitter rh, governing valve kz2, governing valve kz1, feedwater flow transmitter rw, feedwater flow feedback ware aw, drainage flow feedforward ware ad, concentrated magnification adjustment ware gc3 is connected afterwards with the concentrated magnification adjustment ware gc4 of drainage flow transmitter rd, level four in order after being connected with governing valve kz2 to become owner of between regulator gc1 and the secondary controller gc2, main regulator gc1 and secondary controller gc2 connect the back, be connected with governing valve kz1, feedwater flow transmitter rw in order. Thoroughly solved the concentrated multiplying power of water tower when higher relatively, the anticorrosive and scale control of giving the condenser is corroded even and the problem of scale deposit, has guaranteed water tower water level accurate control simultaneously, has avoided the emergence of unit accident.
