Description of the Related Art For example, when a large-scale earthquake occurs, as shown in the past damage example, a water pipe is damaged and its water distribution function is lost. In many cases, the water supply to the affected area is cut off. If such a situation arises, even the inconvenience of a disaster-affected life will make it even more inconvenient. is there. For this reason,
Conventionally, various water storage devices have been proposed, and an example thereof is shown in FIG.

示している。In the conventional water storage device shown in the figure, a water storage tank 1 'is installed in the middle of a pipe as a part of a water pipe, and an inflow pipe 2' is provided from the upstream side of the water pipe to store the water. Tank 1 '
An outflow pipe 3 'extending along the inner bottom surface and extending along the upper surface inside the water storage tank 1' is disposed downstream of the water pipe. The inflow pipe 2 ′ and the outflow pipe 3 ′ which extend inside of the
20, 20,... Are arranged. According to such a water storage device, the water that has flowed into the water storage tank 1 ′ from the inflow pipe 2 ′ through the water hole 20 passes from the water storage tank 1 ′ to the downstream of the water pipe via the outflow pipe 3 ′. Since the normal water supply such as outflow to the side is performed through the water tank 1 ′, the water in the water tank 1 ′ is constantly replaced with the newly supplied water and stays in the water tank 1 ′. Since there is no water, the water can be always stored in the water storage tank 1 'while maintaining the water quality. The arrow in the figure indicates the direction in which water flows.

た。However, in the above-mentioned water storage device, when the water pipe is damaged or the like, the water stored in the water storage tank 1 'flows from the inflow pipe 2' due to a decrease in water pressure in the water pipe. Normally, the water pipe and the water tank 1 'are prevented from flowing backward or from flowing into the water stored in the water tank 1' due to the inflow of dirty water such as mud from a damaged portion. An emergency shut-off valve 6 'is provided between the emergency shut-off valve 6' and the emergency shut-off valve 6 '. If the piping between the storage tank 1 'and the storage tank 1' is damaged, the outflow of water from the storage tank 1 'and the inflow of sewage into the storage tank 1' are inevitable.

And the water sent from the upstream side of the water pipe 4 is disposed by disposing the water passages 2a and 3b extending to the inflow pipe 2 and the outflow pipe 3 in the water storage tank 1, respectively. The water flows into the water storage tank 1 from the water flowing section 2a of the inflow pipe 2 via the inflow pipe 2, and the water in the water storage tank 1 is discharged from the water flowing section 3b of the outflow pipe 3 by the amount of newly flowing water. The water storage tank 1 is configured to form a part of the water pipe 4 such that the water flows out to the downstream side of the water pipe 4 via the pipe 3.

く、貯水槽１内に水を確保することができる。In the water storage device of the present invention, the check valve 12a for preventing the flow of water from the water storage tank 1 to the inflow tube 2 is provided to the water passage portion 2a extending to the inflow tube 2 in the water storage device configured as described above.
According to the present invention adopting such a configuration, even if the emergency cutoff valve 6a does not operate even when the water pipe 4 is damaged at the time of the disaster, the water is stored. Water in the tank 1 does not flow backward from the inflow pipe 2, and water can be secured in the water storage tank 1.

に配しておく必要がある。If the emergency shut-off valve 6b on the outflow pipe 3 is not operated, the outflow of water from the outflow pipe 3 is unavoidable. Since the outflow of the water from the outflow pipe 3 stops when the water is below the water section 3a, the water passage section 3a extended to the outflow pipe 3 is arranged near the upper surface inside the water storage tank 1 as shown in the figure. By leaving, the outflow pipe 3
There is no particular problem because the outflow of water from can be minimized. However, in this case, the water passage portion 2a extending to the inflow pipe 2 is arranged near the bottom surface inside the water storage tank 1 so that the water in the water storage tank 1 flows efficiently from the viewpoint of maintaining the water quality. There is a need.

If the present invention is carried out in an embodiment, the emergency shutoff valve 6b on the outflow pipe 3 side does not operate, or the piping between the emergency shutoff valve 6b of the outflow pipe 3 and the water storage tank 1 is damaged. Even in the case where the water is lost, it is possible to avoid the contamination of the wastewater from the outflow pipe 3 into the water storage tank 1.

The inflow port 14 is configured to be closed by the valve element 16 so that the flow of water is stopped. Conversely, when the water pressure at the inflow port 14 is higher than the pressure at the outflow port 15, the arm 17 is rotated by the water pressure applied to the valve body 16 from the inflow port 14, thereby turning the inflow port 14. It is configured such that water flows from the inlet 14 to the outlet 15 by opening. If such a check valve is provided in the water passage 2a of the inflow pipe 2 from the inflow port 14 side, the flow of water from the water storage tank 1 to the inflow pipe 2 can be prevented, and the outflow from the outflow port 15 side If provided in the water passage 3b of the pipe 3, the flow of water from the outflow pipe 3 to the water storage tank 1 can be prevented.

The check valve 12 may be provided directly in these holes. However, as shown in the illustrated example, a plurality of branch pipes 1 may be provided.
It is preferable that the check valves 12, 9, 19, 19,... Be provided at the open ends of the pipes.
