Description
Affiliated technical field
The utility model relates to a kind of solar water heater and opens wide thermal-arrest attitude and airtight water supply attitude automatic switching control equipment, belongs to the solar water heater system automation field.
Background technology
Wayward because of solar water heater heat-collecting heating thermal source, solar water heater generally is designed to the heating of open type thermal-arrest, in case solar water heater in thermal-arrest heating process because of the phenomenons such as bombing occur that increases of water temperature and hydraulic pressure.Because the design of the open type of solar water heater, solar water heater can not utilize the pressure water supply of running water when supplying water, only depend on the drop of solar water heater to supply water, cause solar water heater when hot-water supply, hydraulic pressure is less, be difficult to be in harmonious proportion, bring inconvenience to use with cold water.
Summary of the invention
The purpose of this utility model is a kind of automatic switching control equipment of design, when the user terminal water valve cuts out, solar water heater can be in open type thermal-arrest heated condition, when the user terminal water valve is opened, can automatically switch to the water supply state that is driven by tap water hydraulic again.
The technical scheme that its technical problem that solves the utility model adopts is: solar water heater system is provided with water inlet pipe, blow-down pipe and outlet pipe, one normally closed electrically-controlled valve is set in the water inlet pipe, be provided with one in the blow-down pipe and often open electrically-controlled valve, one water flow switch controller is set in the outlet pipe, one end of water flow switch controller is electrically connected with power supply, and the other end is electrically connected with Chang Kai and normally closed electrically-controlled valve.When the terminal water valve cut out, current were static, and the water flow switch controller is in off-state, and the solar water heater inlet pipe is in normally off, and blow-down pipe is in normally open, and solar water heater is in the thermal-arrest state that opens wide; When the terminal water valve was opened, the water flow switch controller was in closure state under flow action, triggering solar water heater often opens and normally closed electrically-controlled valve action, make blow-down pipe be in closed condition, water inlet pipe is in open mode, and solar water heater is in the water supply state that is driven by tap water pressure; When the terminal water valve cuts out, current are static, the water flow switch controller returns back to off-state, at this moment, the solar water heater inlet pipe is closed, blow-down pipe is opened, and solar water heater returns back to again and opens wide the thermal-arrest state, and the solar water heater that has reached by the control of terminal water valve opens wide the purpose that automaticallyes switch between thermal-arrest attitude and the water supply attitude by the tap water hydraulic driving.
The beneficial effects of the utility model are that both having solved the solar water heater heat-collecting heating needs unlimited requirement, has solved the problem of present solar water heater hot-water supply insufficient pressure again, and easy to operate; Normally closed electrically-controlled valve is set in water inlet pipe, in blow-down pipe, is provided with and often opens electrically-controlled valve, solved the problem of the loss of power accident solar water heater operate as normal safety.
