Title:
SOLENOID VALVE CONTROL CIRCUIT FOR POWER SAVING
Document Type and Number:
Japanese Patent JP2014206240
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a solenoid valve control circuit for power saving, which is capable of saving power and eliminating failures due to heat generated at the solenoid valve, by reducing supply power to the solenoid valve with a simply configured solenoid valve control circuit for power saving, for a solenoid valve control circuit controlling open/close of a laboratory solenoid valve.SOLUTION: A solenoid valve control circuit 1, for controlling open/close of a solenoid valve 2 for measuring a flow of fluid, includes: an electric path 4 for connecting the solenoid valve 2 and power supply 3 for applying a voltage; timer relay means 5 for disconnecting the electric path 4 after elapsing a predetermined turn-on time; switching type constant voltage means 7 for providing a voltage of a voltage drop at disconnection of the electric path 4 due to operation of timer relay means 5 to the solenoid valve 2; reverse voltage prevention means 8 provided at the side of the solenoid valve 2 near the switching type constant voltage means 7; surge voltage absorption means 9 and a capacitor 10 provided so as to be in parallel to the solenoid valve 2, respectively.
