る。In the above-mentioned conventional water supply control device, when determining the specifications of the water storage tank or the pressurizing pump, the specifications are determined based on a calculation formula based on past data or actual measurement results. I have. However,
Depending on the use of the building, such as a department store, the daily water load may fluctuate greatly. For example, during a sale, etc., the water supply load increases, so if the water supply load exceeds expectations, the tank water storage capacity cannot keep up with the water supply load,
There is a problem that the water supply may be cut off at the water supply destination.

水の劣化を招くことになる。In order to avoid this, it is conceivable to increase the capacity of the water storage tank so that it can cope with an increase in the water supply load. Is difficult to predict, and expanding the capacity of the water storage tank in anticipation of safety leads to an increase in cost, an increase in installation space, and a deterioration in water supply water.

The purpose of the setting is to notify the outside that the stored water amount is decreasing due to an abnormality such as an excessive water supply load or a leakage of the water storage tank, so that the water supply will eventually be cut off.

備えることを特徴としている。In order to achieve the above object, a water supply control device according to the present invention temporarily stores water for water supply from a water supply pipe in a water storage tank, and then supplies the water for water supply in the water storage tank to a predetermined amount. In a water supply control device configured to supply water to a water supply point, a water storage amount detection unit that detects whether a water storage amount of the water storage tank is lower than a preset limit water amount, and the water storage amount is lower than the limit water amount. A water supply amount suppressing unit that suppresses a water supply amount to the water supply point.

Therefore, if a water amount is set as the critical water amount at which water outage is predicted to occur at each water supply point, the water supply amount is suppressed at this point.For example, the same amount as the drawn flow from the water supply pipe to the water storage tank or If the water supply amount is controlled to be less than this, the water storage amount of the water storage tank does not decrease, so that the occurrence of water interruption at each water supply point is avoided.

In a state where water incoming water starts to tank 1 level H I above water water is water, the pressure pump 2 is operated, since the electromagnetic valve 3 is controlled to the open state, is sent from the pressure pump 2 The supplied water is supplied to the water supply pipe L via the solenoid on-off valve 3.
Water is supplied to each water supply point through 3 . The water level of the water storage tank 1 is below the water inlet start level H I, water is started to the water storage tank 1 through water mains L 1. When the water supply load is small and the amount of water supplied to each water supply point, that is, the flow rate of water for water supplied from the water storage tank 1 is smaller than the amount of water drawn into the water storage tank 1, the amount of water stored in the water storage tank 1 is reduced. The water level has increased and the water level has reached the full water level H U
If it exceeds, the water supply to the water storage tank 1 is stopped.

To decrease. When the stored water level falls below the predicted water cutoff level H S , the monitoring device 10 controls the water storage tank 1 based on the detection signal from the predicted water cutoff sensor 6.
Is detected to be lower than the predicted water-stop water level H S , and the electromagnetic on-off valve 3 is controlled to the closed state.

所で断水が生じることはない。As a result, the water supplied from the pressurizing pump 2 is supplied to the bypass pipe L through which the flow control valve 4 is inserted.
Since the water is supplied to each water supply point via 4 , the amount of water supplied to each water supply point is suppressed. Further, since the flow rate of the flow rate adjusting valve 4 is set to be equal to or less than the flow rate drawn into the water storage tank 1, the delivery flow rate from the water storage tank 1 is set to be equal to or less than the flow rate drawn into the water storage tank 1. Become. Therefore, the amount of water stored in the water storage tank 1 does not change or gradually increases, so that the amount of water stored in the water storage tank 1 does not further decrease. Therefore, since the amount of water stored in the water storage tank 1 is ensured, water supply to each water supply point is continuously performed, and there is no interruption of water supply at each water supply point.

When it exceeds, the monitoring device 10 detects this and controls the electromagnetic on-off valve 3 to the open state, so that the water for water supplied from the pressurizing pump 2 is supplied through the electromagnetic on-off valve 3. Therefore, the suppression of the flow rate of the water supply water to each water supply point is released, and sufficient water supply is performed.

What is necessary is just to set so that it can respond to a water supply load. Therefore, it is not necessary to increase the capacity of the water storage tank or to use a higher-performance pump as the pressurizing pump, thereby preventing an increase in cost. Further, since it is not necessary to use a large-capacity water storage tank, the entire water supply control device can be reduced in size. Also, since the capacity of the water storage tank can be set according to the normal water supply load,
Deterioration of the feed water can be avoided.
