Local heating dual-control device for heating network

A heat supply network space heat supply double-control device arranged in a hot water heating system including a 380V power supply, heat source, civilian residence, public building, decontaminator, pressure gauge, thermometer and valve comprises a brake switch, insurance device, electric control valve, programming time controller, two contacts, upper and lower limit indicator light, temperature display regulator and control cabinet. Adjusting the programming time controller and arranging the time frame for indoor temperature of public buildings controlled. Adjusting the temperature display regulator and determining the upper limit temperature and the lower limit temperature controlled in the public buildings. In the time frame arranged, when the indoor temperature of public buildings reaches the upper limit temperature, the electric control valve is adjusted to little and the influent flow is reduced; when the indoor temperature reaches the lower limit temperature, the electric control valve is adjusted to be and the influent flow is increased. In the non-determined time frame, the indoor temperature is changed from the arranged temperature to the normal heat supply state. The utility model has strong practicability and very significant energy-saving effect.
