Abstract
PURPOSE: To eliminate the effect of the magnetic hysteresis onto the attraction force of a magnetic proportional valve due to material by driving the magnetic valve through controlling the ON-time in the same frequency of the pulse wave, in the proportional control valve which proportionally controls the flow rate of the fluid in a gas combustor.
CONSTITUTION: The temperature of the flow rate which is detected in the detection part A is compared with the set value in the comparison part B, and the pulse signal having the width proportional to the magnitude of the flow rate which is determined by the difference described above is fed into a magnetic valve D from the pulse generating part E. The frequencies of the pulse waves for the flow rates l, (m), and (n) are equal, and the ON- time is different according to the magnitude of the flow rate. When a pulse wave is fed into a coil 1, the attractive force proportional to the average electric power is generated, and a movable core 2 stops at the position in balance with a spring 4, and the distance between a valve piece 3 and a valve seat 6 is adjusted, and the flow rate is controlled. Therefore, the effect of the magnetic hysteresis onto the attractive force of the proportional magnetic valve due to material can be eliminated.
