AUTOMATIC WATER SUPPLY DEVICE

摘要

PURPOSE:To enable rapid and automatic water supply of a predetermined amount by operating a preset counter by a unit flow rate pulse oscillator and opening and closing a solenoid valve provided on a water supply pipe. CONSTITUTION:A unit flow rate pulse oscillator 15 generates pulses every rotation of a slit rotating proportionally with the rotation of a rotary vane 9. The signal from these pulses is input in a preset counter 16. A pump 2 and a solenoid valve 20 are electrified by applying a start signal to the counter 16 and the pump 2 is started. When water supply is begun and the water is reached the set water amount, a signal is given from the counter 16 to close the solenoid valve 20 and to stop the pump 2, and water supply of the set water amount is completed.
