Claims (1)
受水弁と該受水弁の前に設置される流量計と購入
した水を一担貯留し需要家へ配水する貯水池を有
する設備において、必要水量を過不足なく貯水池
へ導入するため、貯水池の水位および水位変化率
により必要水量を演算し、該演算水量により弁開
度制御を行う時に、購入水量の最大制限値を考慮
した値とし、制御量の制限回路を設置する事によ
り、最適な水量の確保と受水弁の動作頻度を最小
にした事を特徴とした流量制御装置。 Required for equipment that has a waterway that purchases water from other facilities, a water receiving valve that adjusts the flow rate, a flow meter installed in front of the water receiving valve, and a reservoir that stores the purchased water and distributes it to customers. In order to introduce the correct amount of water into the reservoir, the required amount of water is calculated based on the water level of the reservoir and the water level change rate, and when controlling the valve opening based on the calculated water amount, the maximum limit value of the amount of purchased water is taken into consideration. A flow rate control device that secures the optimal amount of water and minimizes the frequency of operation of the water receiving valve by installing a volume limiting circuit.
