Abstract
The invention is a self-operated temperature-controlling switcher, which can automatically switch the current direction by judging the preset switching temperature and belongs to the technical field of equipment manufacture and installation in heating system and hot water system. The device is provided with two linked temperature-controlling valves which are mutually opening. Temperature sensing alloy makes judgment by sensing the water temperature in a pipeline. When the water temperature is higher than the preset water temperature, the valve A leading to a mixed water cycle branch opens and simultaneously the valve B leading to the return branch of a boiler closes. The hot water in the system pipelines radiates heat at user end circularly by the mixed water cycle branch. When the hot water temperature in the return pipe of the system is lower than the preset temperature, the return branch valve B of the boiler opens and the valve A of the mixed water cycle branch closes. The hot water in the system pipeline flows back to a boiler room through the return branch of the boiler to be heated. The invention has the application benefits of simplified heat metering equipment, lowered cost, simplified operation, reduced maintenance expenses and saved energy source.
