Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-floor water supply system for supplying and distributing water from a water main in a multi-floor building such as an apartment.

[0002]

2. Description of the Related Art Generally, an elevated water tank type and a pressurized type are used as water supply equipment for a multi-storey floor.

In the former, a water receiving tank and a pump connected to the water receiving tank are arranged in a low level, and an elevated water tank is installed on the roof, and a discharge side of the pump is provided on the discharge side of the pump. Is connected to the elevated water tank, and is connected to a pumping pipe provided with a check valve, and a vertical main pipe is connected to the bottom of the elevated water tank, and when the water level of the elevated water tank is low, Water is supplied to the elevated water tank through the water pump by the water pump. Further, when the water level in the elevated water tank rises, the pump is stopped, and water is supplied from the elevated water tank to the water supply pipe of each floor via the vertical main pipe by gravity. The check valve is opened during the operation of the pump, and closed during the stop of the pump to prevent the pumping pipe from falling.

On the other hand, in the case of the latter, a water receiving, pressurizing pump and a pressure tank are installed in a lower layer, and one end is connected to the pressure tank, and the upper end is connected to an air chamber. Pressurization is performed, and water is supplied to the water supply pipes on each floor by the main pipe. Then, when the water pressure in the pipeline falls below a certain pressure, the pump starts and water is supplied to each floor via the pressure tank and the main pipe.

[0005] Examples of this type include those described in Japanese Patent Application Laid-Open No. 3-69732.

[0006]

However, in the above-described conventional apparatus, when the pump does not operate due to a power failure or a failure, there is a problem that the water is cut off and a great deal of trouble is given to residents.

The present invention has been made in view of such a situation in the prior art, and an object thereof is to provide a multi-floor water supply system capable of supplying water to a certain extent even when a pump cannot be operated. Is to do.

[0008]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides a water receiving tank for storing water from an intake pipe connected to a water main, and a pump or pump connected to the water receiving tank. In a multi-floor floor water supply system having a pressure pump, a standing main pipe provided vertically through a building, and a water supply pipe connected to the standing main pipe, one end of an auxiliary water supply pipe is connected to the water intake pipe. It has a configuration provided with a switching valve.

According to the present invention constructed as described above, when the pump stops due to a power failure or a failure, the switching valve provided on the intake pipe is opened. In response to this, water is directly taken from the water main and sent through the auxiliary water supply pipe. At this time, generally, water can be sent to the height of the third floor by the water pressure of the water main. Thus, even when the pump cannot be operated, a certain amount of water can be supplied.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a multi-floor water supply system according to an embodiment of the present invention.

FIG. 1 is an overall configuration diagram showing an embodiment in which a multi-floor water supply system of the present invention is used in an elevated water tank system.

As shown in FIG. 1, the multi-floor floor water supply system of this embodiment has an elevated water tank 2 provided on the roof of a building 1, a water receiving tank 3 provided on the surface of the ground, and one end of a water main 4. And a water intake pipe 6 having a water stop valve 5 in the middle and the other end opened into the water receiving tank 3,
Pump 7 for feeding water to the elevated water tank 2 through the
A check valve 9 which is provided at the lower part of the pump and is opened when the pump 7 is in operation and is closed when the pump is stopped, a main pipe 10 which penetrates the building 1 and has an upper end connected to the elevated water tank 2, and one end of the main pipe 10.
And a switching valve 13 provided on the water intake pipe 6 between the water main pipe 4 and the water shutoff valve 5, and a switching valve at one end. 13 has an auxiliary water supply pipe 14 having the other end connected to the vertical main pipe 10, and a tap 15 provided on the auxiliary water supply pipe 14.

In this embodiment, when the pump 7 stops due to a power outage or failure, the water in the elevated water tank 2 is discharged from the tap 12.
Is reduced by the release of water, and water is cut off over time. At this time, the switching valve 13 is opened, the water in the water main 4 is directly taken into the auxiliary water supply pipe 14, and the water is supplied to the main pipe 10. Thus, water is supplied to the water supply pipe 11 via the main pipe 10 within the range of the water pressure of the water main pipe 4. Generally, for example, water can be sent to the third floor, and residents on the fourth floor and above can draw water through the tap 15 provided on the lower floor.

FIG. 2 is an overall configuration diagram showing another embodiment in which the multi-floor water supply system of the present invention is used in a pressurized manner. In addition,
The same components as those shown in FIG. 1 described above are denoted by the same reference numerals. That is, 1 is a building, 3 is a water receiving tank, 4 is a main water pipe, 5 is a water stop valve, 6 is a water intake pipe, 9 is a check valve, 10 is a main pipe, 11 is a water supply pipe, and 12 and 15 are water taps. It is.

As shown in FIG. 2, a water supply system for a multi-floor floor according to another embodiment has a pressurizing pump 18 for pressurizing and sending water in a water receiving tank 3, and a pressure pump 18 between the pressurizing pump 18 and the main pipe 10. It has a pressurized tank 16 interposed and an air chamber 17 provided above the vertical main pipe 10 and opened when the pressure in the vertical main pipe 10 becomes higher than a certain level.

In this other embodiment, when the pressurizing pump 18 is stopped due to a power failure or a failure, the switching valve 13 is opened and water from the water main 4 is directly taken into the auxiliary water supply pipe 14, and the vertical main pipe 1 is taken out.
For example, residents up to the third floor can draw water through the water supply pipe 11, and residents on the fourth floor and above can pump water through the faucet 15.

In each of the embodiments configured as described above, even when the pumps 7 and 18 cannot operate, a certain amount of water can be supplied.

[0018]

Since the present invention is constructed as described above, it is possible to supply a certain amount of water even when the pump cannot be operated, whereby it is possible to supply the resident with the water required for a while. There is an effect that it is possible to reduce annoyance due to a power failure or a failure.
