Abstract
An automatic fluid-supply apparatus for a boiler system automatically controls an amount of fluid being supplied to a fluid tank of the boiler system. The automatic fluid-supply apparatus is provided with a flux detecting portion which comprises a rotor assembly disposed inside a fluid-supply pipe to rotate in proportion to the flux of the fluid flowing from a fluid-supply source to the fluid tank and a HALL sensor disposed close to the rotor assembly at an outer surface of the fluid tank. The HALL sensor is intermittently turned ON/OFF in response to permanent magnets provided to the rotor assembly. A controller compares the ON/OFF frequency with a preset ON/OFF frequency range and transmits an ON/OFF signal to a solenoid valve.
Claims6
An automatic fluid-supply apparatus for a boiler system comprising:
- a fluid-supply pipe connected to a fluid-supply source and providing a passage for fluid flowing from the fluid-supply source line;
- a fluid tank connected to the fluid-supply pipe and receiving the fluid being supplied through the fluid-supply pipe;
- a fluid discharging pipe connected to the fluid tank and discharging the fluid in the fluid tank to a heating system;
- a fluid-return pipe for returning the fluid from the fluid discharging pipe to the fluid tank;
- means disposed in the fluid tank and for detecting flux of the fluid flowing in the fluid tank;
- a valve disposed between the fluid-supply source line and the fluid-supply pipe and controlling flow of the fluid therebetween;
- and
- a controller magnetically connected to the flux detecting means and electrically connected to the valve so as to detect ON-OFF frequency, and for comparing whether the detected ON-OFF frequency is in an ON-OFF frequency range to thereby open or close the valve, the ON-OFF frequency range being preset in the controller.
