Abstract
PURPOSE: To control the opening of an outlet valve without causing any disturbance in water supply flow control by keeping the opening of the outlet valve at a value corresponding to the r.p.m. of a water supply pump or a set r.p.m. thereof. CONSTITUTION: A function generator 20 for setting the opening of an outlet valve has such characteristics as the opening of the outlet valve increases as the water supply r.p.m. increases. An r.p.m. 14a corresponds to the lowest r.p.m. and the outlet valve is fully closed when the r.p.m. is lower than Na. When the inlet pressure of boiler is high, by some extent, than the delivery pressure of a water supply pump at the lowest r.p.m., the outlet valve is fully opened and water supply flow control is conducted stably by simply regulating the r.p.m. When increase of water supply is requested, the r.p.m. is increased and the outlet valve is opened in the direction contributive to increase water supply with no time lag. When decrease of water supply is requested, the r.p.m. is decreased and the outlet valve is closed in the direction contributive to decrease water supply with no time lag. The outlet valve is fully closed at the r.p.m. Na corresponds to the lowest r.p.m. and low flow rate water supply flow control is conducted stably in the region above the lowest r.p.m.
