FIELD: power engineering, possible use in safety devices for water-heating system, in particular for solid fuel based water heating equipment.
SUBSTANCE: device contains temperature-sensitive control element, positioned in hot water circulation contour with tight contact of its extending rod and valve, mounted in distributor body, so that aforementioned rod in its working position ensures possible simultaneous connection of hot water contour with draining pipe and opening of system cold water inlet, and also according to second variant provides for possible passage of cold water through heat exchanger, positioned in system hot water outlet or directly in water heating equipment, where body of distributor is attached to water heater (boiler) body in such a way, that valve of distributor is pressed to distributor body saddle by spring pressure.
EFFECT: prevented overheating of heating equipment, ensured safety in water-heating systems in cases of emergency power failure.
