給水制御装置。 In a water supply control device that controls the water supply flow rate by controlling the rotation speed of a water supply pump and further controlling the valve opening degrees of a water supply control master valve and a water supply control slave valve connected in parallel, the above-mentioned water supply control master valve and water supply control are provided. One comparator inputs a valve opening signal from a child valve, and the other comparator inputs a rotation speed correction signal from a signal generator, and turns ON from one and the other comparator.
- One switch and the other switch that are opened and closed by the OFF signal, an adder that inputs the rotation speed signal from the control device and adds or subtracts the rotation speed correction signal input from the one switch and the other switch, and the rotation speed from the adder. It is equipped with a pump power device that inputs a command signal to control the rotation speed of the water supply pump, and lowers the rotation speed of the water supply pump when the water supply is gradually increased when the water supply control master valve opens.
A water supply control device having a parent and child valve, characterized in that the water supply pump rotation speed is increased when the water supply gradually decreases when the water supply control parent valve closes.
