[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water distribution system for distributing water sent from a water purification facility to a water supply facility for supplying water to each of the terminals at the end.

[0002]

Conventionally, in this type of water distribution system,
In the middle of the water supply facility that supplies water from the water purification facility to each house at the end,
There is a distribution reservoir. This distribution reservoir has the function of adjusting the time variation of the distribution amount, and the function of maintaining a predetermined amount of water and water pressure when an accident occurs on the upstream side of the distribution reservoir.
These functions will mitigate the impact on water supply in the event of abnormalities such as facility accidents, water shortages, and water quality accidents that occur on the upstream side.

The water discharged from the water purification facility is sent to and stored in a distribution reservoir via a water pump or the like, and the water flowing out from the distribution reservoir uses natural flow utilizing the difference in height or the pump pressure of the water pump. Is supplied to the water supply equipment via a water distribution pipe, and this water supply equipment supplies water to each terminal unit. However, when the water supply facility supplies water to a middle or high-rise building, for example, an apartment house with four or more floors, the water pressure sent through the water pipe is not sufficient, so It was not possible to supply water to the house.

For this reason, water supply facilities such as apartment houses for middle- and high-rise buildings have a water tank for storing water in the basement of the building and a water tank in a high place of the building, and the water is sent through a water pipe. The water was pumped up from the receiving tank to the aquarium at the height of the building, and water was supplied from the aquarium at the height to each house in the building.

[0005]

However, since the water receiving tank and the like are not sufficiently managed and maintained and inspected, the water tank is not hygienic and the safety of drinking water cannot be ensured. There was a flaw.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art, and the purpose thereof is to eliminate the need for a water tank or the like provided in middle and high-rise buildings. In addition, it is to provide a sanitary and excellent water distribution system that can supply water directly to middle and high-rise buildings.

[0007]

In order to achieve the above object, a water distribution system according to the present invention has the following constitution. That is, a tank device having a water storage function for accumulating a large amount of water and a high-pressure water distribution function for increasing water distribution pressure to distribute water is provided in the waterway from the water purification facility to the water supply facility.

Further, it is preferable that the tank device includes a tank formed in a spherical shape or an egg shape.

Further, the tank device is provided with compressed air supply means, the compressed air supplied from the air supply means is put into the tank, and the inside of the tank is constantly pressurized.
The compressed air may be used to supply the water in the tank to the water supply facility.

Further, the tank device preferably includes a plurality of tanks and selectively supplies the water in each tank to the water supply equipment.

[0011]

[Operation] The water discharged from the water purification facility is sent to and stored in the tank device. After that, the tank device raises the water pressure and sends the water to the water supply facility, and the water supply facility supplies water to each house. Since this tank device has the above-mentioned water storage function and high-pressure water distribution function and can send water directly to each top-floor house of middle and high-rise buildings, water tanks etc. installed in conventional middle and high-rise buildings can be used. It becomes unnecessary.

Further, when the tank is formed in a spherical shape or an egg shape, it is possible to withstand a high pressure by receiving the pressure of water or the like in the tank on the spherical side surface,
A large amount of water can be stored inside the tank.

Further, when the tank device is provided with compressed air supply means and the water in the tank is supplied to the water supply equipment by using the compressed air, even if the water level in the tank changes, the compressed air in the tank The pressure of the water supplied from the tank is constant because the pressure can be easily adjusted. At that time, since the tank is constantly pressurized, it is possible to prevent emission of disinfection residual chlorine dissolved in water.

Further, the tank device is provided with a plurality of tanks, and when the water in each tank is selectively supplied to the water supply facility, if the amount of water in one tank decreases, the water is stored in the other tanks. Water is supplied to the water supply facility.

A height difference is provided between the distribution reservoir 12 and the tank device 14, and the water is sent to the tank device 14 by natural flow through the distribution pipe 13.

The tank device 14 is provided with, for example, two tanks 14a, has a water storage function that is alternately used to store a large amount of water in the tank 14a, and can increase water distribution pressure to distribute water to the water supply equipment 11. It has a high-pressure water distribution function. Therefore, by providing the tank device 14 in the middle of the water channel, the water receiving tank or the like provided in the conventional middle- and high-rise buildings becomes unnecessary, and each door 1 in these buildings can be eliminated.
0 can supply sanitary water directly to the distribution reservoir 12
Since it can play a complementary role, the efficiency and economic efficiency of water distribution and water supply will be improved. It should be noted that the tank device 14 can be installed at any place in the piping network of the water distribution pipe 13, and can be installed as appropriate in consideration of the water pressure balance of the piping network of the water distribution pipe 13 and the water supply equipment 11. Further, the tank device 14, when sending water to the water supply facility 11,
There is no need to install it in a high place to obtain the required water supply pressure, and since it can be installed in lowlands, it is easy to provide a strong seismic design and maintenance is easy.

As shown in FIG. 2, these tanks 14a are, for example, egg-shaped, made of prestressed concrete, and installed on the ground surface 15. Tank 1
When 4a is formed in an egg shape, even if the pressure of water or the like inside the tank 14a becomes high, the high pressure can be received by the spherical side surface, so a large amount of water should be stored inside the tank 14a. You can As a result, both tanks 14a
However, for example, when storing a large amount of water of about 8000 cubic meters in total, the tank device 14 sufficiently plays a complementary role of the water reservoir 12.

Between the water pipe 13 and each tank 14a,
Pipes 16 each having a check valve 16a are attached to supply water from the reservoir 12 to each tank 14a. A pipe 17 and a pipe 18 are attached to the upper position of each tank 14a, and each pipe 17 is provided with a safety valve 17a for adjusting the air pressure inside the tank 14a.
Are each provided with a valve 18a used when sending compressed air into the tank 14a. And each pipe 18
Is a storage tank 1 for storing compressed air via a valve 18a.
9, the air storage tank 19 is further connected to a compressor 20. When the compressor 20 operates, the compressed air in the air storage tank 19 is transferred to the inside of each tank 14a to each pipe 18 and each valve 18
It is designed to be sent via a. In addition, 18b is
This is a switching valve.

Further, the tanks 14a are connected to each other by a pipe 21 provided under the tanks 14a, and are also connected to the water supply equipment 11 via a valve 21a attached to the pipes 21. .

Next, the operation of this embodiment will be described.

Water purified by the water purification facility 9 is received and stored in the distribution reservoir 12 via the supply pipe 9a. The water discharged from the distribution reservoir 12 is stored in the tank 14 a via the distribution pipe 13.
The pressure of the water sent through the water distribution pipe 13 is
When the pressure is higher than the internal air pressure, water enters the tank 14a through the check valve 16a and is stored in the tank 14a.

When the water in the tank device 14 is supplied to the water supply equipment 11, the compressor 20 operates to move the compressed air in the storage tank 19 to the valve 18a and the pipe 18 on one side.
Through the inside of the tank 14a. This tank 1
When the pressure of the air inside 4a is higher than the pressure of the water sent through the water distribution pipe 13, the water stored inside the tank 14a is supplied to the water supply equipment 11 through the valve 21a and the pipe 21, and the doors 10 Is directly supplied to. At this time, if the pressure of the air inside the tank 14a becomes too high, the pipe 1
The safety valve 17a of No. 7 operates to reduce the air pressure inside the tank 14a.

If the amount of water in the tank 14a on one side decreases,
The valve 18a on one side is closed to reduce the air pressure inside the tank 14a, and the water sent through the water distribution pipe 13 is put into and stored inside the tank 14a through the check valve 16a and the pipe 16. At the same time, the compressed air is sent to the inside of the tank 14a on the other side through the valve 18a and the pipe 18 on the other side, and the water stored in the tank 14a is supplied to the water supply equipment 11 via the pipe 21 with the valve 21a. And is directly supplied to each door 10.

In this case, since compressed air is constantly put in the tank 14a to be constantly pressurized and the compressed air is used to supply the water in the tank 14a to the water supply equipment 11, the water level in the tank 14a fluctuates. However, the pressure of the compressed air inside the tank 14a can be easily adjusted, and the pressure of the water supplied from the tank 14a is always constant. Furthermore, since this tank 14a is constantly kept under pressure, it prevents the release of residual chlorine for disinfection dissolved in water.
The disinfection effect of chlorine can be maintained.

As a specific example, one tank 14a
If the internal volume is 4000 cubic meters, for example,
The pressure of the air storage tank 19 is set to about 5 to 7 kilograms / square centimeter in consideration of a margin, and the tank 14a
The water pressure inside is set to about 3.5 kilograms / square centimeter. This is because when water is directly connected to a three-story medium-rise building from the tank 14a to supply water, the water pressure is at least about 2.0 to 2.5 kilograms / square centimeter, and for example, a five-story high-rise building. When water is directly supplied to an object from this tank 14a, the water pressure is 3.0.
This is because it is necessary to set about 3.5 kg / cm 2. As long as the water in the tank 14a is supplied to the water supply facility 11 at such a water pressure, there is no particular problem even if the building is a one-story building.

Although the air storage tank 19 and the compressor 20 in this embodiment correspond to the compressed air supply means, the compressed air supply means is not limited to this structure but may have various other structures. Good.

The present invention is not limited to the above-described embodiments, but various modifications can be made. For example, the tank 14a may be formed in a spherical shape, or other than the egg shape and the spherical shape. It may be formed or may be made of steel. Further, in the above-mentioned embodiment,
The tank device 14 includes two tanks 14a, but is not limited to this. One tank or three tanks 14a are provided.
It may have more than one tank. Incidentally, the tank device 1
No. 4 need not have a compressed air supply means as long as water can be distributed by increasing the water distribution pressure. Furthermore, as another embodiment, the tank 14
In order to increase the water pressure in a and perform high-pressure water distribution, as shown in FIG. 3, a gas bag 22 made of, for example, neoprene rubber is provided in the tank 14a, and compressed air or the like is put in the gas bag 22. It may be inflated like a virtual line to increase the water pressure in the tank 14a.
