The device has the advantages that without changes of the original equipment, the solenoid valves can be automatically closed in case of different flows of the water inlet pipe and the water return pipe of the boiler, so that the control is simple, the cost is low, and the safety is high; meanwhile, the device achieves the functions of automatic heating and water feeding, so as to save energy.
Description
Technical field
The present invention relates to boiler safety control technology field, specifically boiler safety Automatic-heating water-supply apparatus.
Background technology
the hot water produced in boiler directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator, mechanical energy is converted to electric energy again.There is provided the boiler of hot water to be called hot-water boiler, be mainly used in life, in industrial production, also have a small amount of application.In hot-water boilers a lot of be at present all by electrical heating by delivery to user for resident.Due to hot-water boiler not having checkout gear, when in pipeline or tube system there is water leakage situation in the equipment of resident family, can not Timeliness coverage, cause the wasting of resources.Some boilers possess pressure-detecting device, but do not possess the function not stopping when automatic loading water and water temperature reach setting value heating, and cause energy waste.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of boiler control system, when the water inlet pipe of boiler is different with the flow of return pipe, Self-shut electromagnetic valve, overhauls; Stop heating when water temperature reaches setting value, water temperature reheats lower than during design temperature 5 degree; When the water level in boiler is lower than the water level set, pump working adds water, and when reaching the water level of setting, water pump quits work.
The present invention realizes with following technical scheme: a kind of boiler safety Automatic-heating water-supply apparatus, be included on the water supply line of boiler and water return pipeline and a magnetic valve and pressure sensor are all installed, have in boiler erection and detect the temperature sensor of water temperature and the liquid level sensor for detecting boiler water level, respectively with pressure sensor, the controller that liquid level sensor and temperature sensor connect, the warning device be connected with controller respectively and the executing agency for shut electromagnetic valve, controller exports and is connected to power supply relay and water pump relay, power supply relay is connected with the switch of boiler, water pump relay is connected with the power switch of boiler water pump.
The invention has the beneficial effects as follows: do not changing on the basis of existing equipment, when the water inlet pipe of boiler is different with the flow of return pipe, Self-shut electromagnetic valve, control simple, cost is low, and security is high; Stop heating when water temperature reaches setting value, reheat when water temperature asks 5 degree lower than setting; When the water level in boiler is lower than the water level set, pump working adds water, and when reaching the water level of setting, water pump quits work, and reduces energy waste.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
In figure: 1, magnetic valve, 2, pressure sensor, 3, controller, 4, executing agency, 5, warning device, 6, boiler water pump, 7, liquid level sensor, 8, water pump relay, 9, temperature sensor, 10, power supply relay.
Detailed description of the invention
As shown in Figure 1, a kind of boiler safety Automatic-heating water-supply apparatus all installs a magnetic valve 1 and pressure sensor 2 on the water supply line and water return pipeline of boiler, have in boiler erection and detect the temperature sensor 9 of water temperature and the liquid level sensor 7 for detecting boiler water level, respectively with pressure sensor 2, the controller 3 that liquid level sensor 7 and temperature sensor 9 connect, the warning device 5 be connected with controller 3 respectively and the executing agency 4 for shut electromagnetic valve, controller exports and is connected to power supply relay 10 and water pump relay 8, power supply relay 10 is connected with the switch of boiler, water pump relay 8 is connected with the power switch of boiler water pump 6.Executing agency 4 is connected with two magnetic valves 1, for the keying of Controlling solenoid valve 1.Power supply relay 10 is connected with the power switch of boiler, for controlling the Kai Heguan of power switch.Water pump relay 8 is connected with the power switch of boiler water pump 6, for controlling the keying of pump power.
The course of work: under normal operation, supply channel is identical with the data that pressure sensor on water return pipeline collects, and output instruction signal is not to executing agency for controller, and magnetic valve is in opening.When the reading on two pressure sensors is different, illustrate that in pipeline or tube system, drainage appears in other resident family's equipment, now the flow signal of two pressure sensor collections is delivered to controller respectively, after the process of controller, output instruction signal is to executing agency, executing agency's action, shut electromagnetic valve, then checks fault.In addition, the temperature signal that temperature sensor and liquid level sensor are gathered and liquid level signal are sent to controller, boiler electricity source switch is closed by power supply relay when water temperature reaches set value calculation device, stop heating, when water temperature is lower than design temperature 5 degree, controller, by power supply relay starting trouble power switch, reheats; When the water level in boiler is lower than the water level set, controller starts pump power switch by water pump relay, and water pump adds water, and when water level reaches the water level of setting, controller is by water pump cut-off pump power switch, and water pump quits work.
