On the other hand, one method that has been conventionally adopted is to install a water tank at the top of the building, pump it up from the ground by pumping it up to store tap water, and use gravity to remove water from this tank. This is a method of distributing water within the building. As another method, there is a method in which a water tank is provided above ground or underground and tap water stored here is distributed to the building by a pump. All of them use water tanks to enable smooth water supply to the building.

水が停止するように構成されている。FIG. 3 is a structural view showing an example of a conventional water storage tank. The figure shows a water tank and a mechanism for controlling water supply to the water tank. Water is supplied to the water tank 101 from a water pipe 102. Tap water is mainly injected through the main valve 103 into a water injection pipe 104.
Water is supplied from the pipe, but part of the water is guided to the pilot pipe 105. At the tip of the pilot pipe 105, a float 107 that is displaced along with the water level 106, and a sub valve 10 that is closed in conjunction with the displacement of the float 107 when the water level exceeds a predetermined full level.
8 are provided. When the sub valve 108 is closed, the water pressure in the pilot pipe 105 on the primary side increases. Main valve 103
Is a pilot operated valve that opens and closes by using the water pressure of the pilot pipe 105 as pilot pressure. That is, the sub valve 108 is closed due to the rise of the water level, and when the water pressure in the pilot pipe 105 exceeds the driving pressure, the main valve 103 is also closed and the water supply to the water storage tank 101 is stopped.

There is a configuration in which a pilot valve that is a pressure / power amplifier is added to the pilot operated valve that is the main valve. The latter amplification function of the pilot valve is achieved by changing the spool valve in the pilot valve so as to balance the water pressure in the pilot pipe 105 when the water pressure in the pilot pipe 105 changes, and switching the flow path of a flow larger than the flow in the pilot pipe. It This large flow is taken out as an output, and this water pressure operates the pilot operated valve that opens and closes the flow path from the water pipe 102 to the water injection pipe 104.

は、異常原因を調査し、対処を行うことができる。FIG. 4 is a block diagram showing a signal system of a conventional water tank. The conventional water tank has a water level detection sensor consisting of a sensor unit 110 and a water level detection circuit 112 in the control panel 111, but this is for the purpose of water level monitoring separate from the water supply control described above. . In the conventional example shown in the figure, the sensor unit is a plurality of electrode rods having different lengths, and a current flows between the electrodes in contact with the water surface, but no current flows in the electrodes not in contact with the water surface. The water level detection circuit 112 determines the range in which the water level exists by measuring the current flowing through each electrode. The alarm circuit 14 notifies the building manager of an abnormality by a lamp display, a buzzer sound, etc., for a water level below a predetermined water level and a water level above a predetermined water level, respectively. The building manager who receives the alarm can investigate the cause of the abnormality and take corrective action.

ロット管５にソレノイド弁９を有することである。FIG. 1 is a schematic diagram of a building water tank which is an embodiment of the present invention. The figure shows a water tank and a building water tank water supply control device that is a mechanism for controlling water supply to the water tank. Water is supplied from the water pipe 2 to the water tank 1. Tap water is mainly supplied from the water injection pipe 4 through the main valve 3, and part of the tap water is guided to the pilot pipe 5. The main valve 3 is a pilot operated valve that opens and closes by using the water pressure of the pilot pipe 5 as pilot pressure. A float 7 that is displaced along with the water level 6 and a sub valve 8 are provided at the tip of the pilot pipe 5. The float 7 is connected to a rod having a fulcrum at the tip portion of the pilot pipe 5, the rod is rotated about the fulcrum by the vertical movement of the float 7, and the auxiliary valve 8 is opened and closed in conjunction with the rotation of the rod. Has become. This embodiment is shown in FIG.
What is different from the conventional example is that a pilot valve 5 between the main valve 3 and the sub valve 8 has a solenoid valve 9.

ける水圧に比べて低い。主弁３はパイロット管５の水圧

開かれているように構成される。Since water is supplied from the water pipe 2 to the pilot pipe 5 through a narrow throttle, the water pressure in the pilot pipe is higher than that in the water pipe 2 and the water injection pipe 4 when water is flowing. Low. The main valve 3 uses the water pressure of the pilot pipe 5 as a pilot pressure, and the main valve 3 is configured to be opened at this low pressure.

る。When the water level 6 rises due to the water supply from the water injection pipe 4, the float 7 floating on the water surface also rises. When the water level 6 reaches a predetermined full water level and the auxiliary valve 8 is closed in conjunction with the rod connected to the float 7, the water flow in the pilot pipe 5 is blocked, and the water pressure in the pilot pipe is the water pressure supplied to the water pipe 2. Rise to. The main valve 3 receives this pressure as pilot pressure and closes, and water supply from the water injection pipe 4 to the water tank 1 is stopped.

始される。On the contrary, when the water stored in the water storage tank 1 is used and the water level 6 is lowered, the float 7 is lowered and the sub valve 8 is opened. Then, since water flows through the pilot pipe 5, the water pressure in the pilot pipe 5 decreases, the main valve is opened, and water supply is started.

駆動圧となって、主弁３は閉じ、給水が停止する。The mechanism for opening and closing the sub-valve 8 in conjunction with the float 7 will not close even if the water level 6 reaches the full level if the movable part of the mechanism does not move smoothly due to rust or scale. Failure can occur. When this happens, the water supply does not stop and the water level 6 rises above the full water level. When the water level exceeds the full water level and becomes an alarm water level, a specific electrode of the sensor section 10 of the water level detection sensor comes into contact with the water surface, and when a current flows through this electrode, the water level detection circuit 12 in the control panel 11 causes the solenoid valve drive circuit 13 to operate. Give an alarm to. Solenoid valve drive circuit 13
When an alarm is received, a current is passed through the solenoid of the solenoid valve 9, the movable piece in the solenoid is displaced, and the solenoid valve 9
Is closed to shut off the water flow in the pilot pipe 5. As a result, the water pressure in the pilot pipe 5 rises in the same manner as when the sub valve 8 is closed, and the pilot pressure of the main valve 3 becomes the drive pressure for closing the main valve, so that the main valve 3 is closed and the water is not supplied. Stop.

いる。When the water level detection circuit 12 detects an alarm water level from the current of the sensor section 10, the water level detection circuit 12 notifies the solenoid valve drive circuit 13 and the alarm circuit 14 as well, and the alarm circuit 14 displays a lamp or a buzzer sound. Notify the administrator of the abnormality. As the operation of the solenoid valve drive circuit 13 when the water level detection sensor detects a decrease in water level after the solenoid valve 9 is closed and the water supply is stopped, the solenoid valve 9 is automatically opened to restart the water supply or the building management. There are two ways, one is to open the solenoid valve 5 and restart the water supply after waiting for the reset operation after the person investigates and repairs the cause of the abnormality,
The solenoid valve drive circuit 13 has a switch for selecting these two modes. The water level detection sensor of the conventional example was intended only for water level monitoring, but in the present embodiment, it is connected to the solenoid valve drive circuit 13 and has a water supply control function, which is one of the building water tank water supply control devices. It's a part.

In order to drive the solenoid valve 9 only when the float 7 or the sub-valve 8 fails, a power source such as electricity is not required separately in addition to hydraulic power for the normal opening / closing operation of the main valve 3. It consumes power. Moreover, since the solenoid valve 9 only needs to be able to control the water flow of the pilot pipe 5 having a small amount of water and low pressure, it does not require mechanical strength as compared with the case where the water pipe 2 and the water injection pipe 4 are directly opened and closed by an electromagnetic valve. Yes, the size can be reduced, the manufacturing cost can be suppressed, and the running cost can be suppressed because the power consumption is small.

る。Further, in the present embodiment, the solenoid valve 9 is provided in the pilot pipe 5 between the main valve 3 and the sub valve 8. However, the solenoid is juxtaposed to the sub valve 8 and the movable piece in the solenoid is used as the sub valve. The secondary valve 8 itself may be used as the solenoid valve 9 in connection with the solenoid valve 9. In this configuration as well, since no current normally flows through the solenoid, the sub valve 8 works in conjunction with the float 7. But,
When the water level sensor detects an alarm water level, the solenoid is energized to exert a force on the sub-valve 8 via the movable piece, moving the float 7 or the sub-valve 8 that has lost smoothness to move the sub-valve. Close valve 8. As a result, the pilot pressure of the main valve 3 is increased to the driving pressure, the main valve 3 is closed, and the water supply is stopped.

ンニングコストも抑制できる。According to the building water tank water supply control apparatus of the present invention, the solenoid valve is closed and the pilot valve of the main valve is closed when the water level sensor detects an alarm water level above the full level, even if the sub valve or the float fails. The pressure rises to the driving pressure, the main valve closes, and the water supply to the water tank stops. For this reason, even if the building manager does not notice the alarm, or if he / she is in a remote place and is performing remote monitoring, water will not overflow from the water tank and be damaged. Since the solenoid valve is installed in the pilot pipe with a small amount of water and low pressure, it can be smaller than the solenoid valve installed in water pipes and water injection pipes, and it can reduce manufacturing costs, and it also consumes less electric power, which reduces running costs. it can.
