Abstract
PURPOSE: To accurately control feed gap pressure so as to obtain its objective value in a proportional control valve used for a gap combustion equipment, by transmitting force, applied to a pressure detecting element, directly to the valve and regulating the gas pressure in a secondary pressure chamber in accordance with the force applied to the valve.
CONSTITUTION: If a motor 25 in an electrically driven part B is rotated, a nut 27 locked its motion by a screw 26 is vertically moved to adjust tension of a spring 24 and change its force applied to a pressure detecting element 22. The force applied to the pressure detecting element 22 is directly transmitted in a state as it is to a valve 17. Then gas pressure in a secondary pressure chamber 18 can be regulated in accordance with the force applied to the valve 17 by the principle of governor action. Accordingly, the pressure detecting element 22 is caused in a state of detecting the gas pressure in the secondary pressure chamber 18, thus dispersion of the gas pressure in the secondary pressure chamber 18 due to hysteresis can be eliminated.
