Title:
FLOW RATE CONTROL VALVE
Document Type and Number:
Japanese Patent JPS604681
Kind Code:
A
Abstract:
PURPOSE:To simplify the structure of a flow rate control valve by previously storing current-flow rate operation characteristics of the flow rate control valve in a central control unit so that the flow rate is controlled corresponding to an operation signal of an operation part. CONSTITUTION:Current-flow rate operation characteristics of a flow rate control valve 7 are previously stored in a central control unit 2 having information processing means. On the basis of these tables, the flow rate is controlled corresponding to an operation signal from an operation part 1. The central control unit 2 includes CPU8, a memory 9, a peripheral interface adapter 10, an analog- digital unit 11 and a solenoid valve amplifier 12. A control signal is sent through the amplifier to a hydraulic control valve and the flow rate control valve 7. The remote control for the flow rate can be easily made because a feedback system is not used.
