TEMPERATURE CONTROL DEVICE OF SERVICE WATER Russian patent published in 2011 - IPC F24D19/10 G05D23/02 

FIELD: power industry.

SUBSTANCE: temperature control device for service water heated by means of heat medium, namely by means of water of central heating station in heat exchanger, with service water gate regulating the service water flow to heat exchanger and with heat medium gate regulating the heat medium flow from heat exchanger. Service water gate includes service water valve seat and cylindrical or conical element of service water valve gate, which is movable relative to it, and heat medium gate includes heat medium valve seat and cylindrical or conical element of heat medium valve gate, which is movable relative to it. Service water gate and heat medium gate interact with each other by means of gate pin; at that, control adjusted as to pressure is provided, which acts depending on service water intake to the gate pin and as a result to service water gate, or adjusting or opening or closing one, and besides, known thermostatically controlled regulator is provided, which acts only on heat medium gate, mainly directly on the element of heat medium valve gate, or regulating it depending on service water temperature, namely measured with temperature sensor after service water leaves the heat exchanger. Element of heat medium valve gate is located in or on gate pin in movable way or with possibility of being moved or detached relative to longitudinal axis of gate pin, and service water gate is connected to gate pin firmly and rigidly. Heating element with the above mentioned device is also described.

EFFECT: simplifying and improving operating reliability, and implementing the independent temperature control.
