DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply system for a multi-storey floor of an apartment or the like.

[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.

[0003] In the former, a water receiving tank and a pump connected to the water receiving tank are provided on the lower layer, an elevated water tank is installed on the roof, and an elevated water tank is connected to the discharge side of the pump. A pump pipe with a check valve interposed is connected, and a standing pipe is connected to the bottom of the elevated water tank. When the water level of the elevated water tank is low, water is supplied to the elevated water tank via the pumping pipe by the pump. I do.

[0004] When the water level in the water tank rises, the pump stops, and water is supplied from the elevated water tank to the water supply pipe on each floor via a vertical pipe by gravity.

[0005] 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.

In the latter, a water receiving tank, a pressurizing pump, and a pressure tank are installed in the lower layer, and one end is connected to the pressure tank, and the upper end is constantly pressurized in a standpipe connected to the air chamber. Water is supplied from the standing pipe to the water pipe on each floor. When the water pressure in the pipeline falls below a certain level, the pump starts and water is supplied to each floor via a pressure tank and a standing pipe.

Incidentally, Japanese Patent Application Laid-Open No.
-69732 can be mentioned.

[0008]

In the above-mentioned prior art, when the pump does not operate due to a power failure or a failure, there is a problem that water is cut off and a lot of trouble is given to residents.

An object of the present invention is to provide a multi-floor water supply system capable of supplying water to a certain extent even when the pump does not operate.

[0010]

SUMMARY OF THE INVENTION The object of the present invention is to provide a water receiving tank for storing water from an intake pipe connected to a water main, a pumping or pressurizing pump connected to the water receiving tank via a conduit,
In a multi-floor water supply system composed of a standpipe provided vertically through a building and a supply pipe connected to the standpipe, the conduit is provided with a switching valve connected to an auxiliary supply pipe. Achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of a multi-story water supply system showing an embodiment in which the present invention is applied to an elevated water tank system, and FIG. 2 is a multi-story floor water supply in which an embodiment of the present invention is used in a pressurized manner. It is a whole block diagram of equipment.

In FIG. 1, 1 is a building having 6 floors,
2 is an elevated water tank provided on the roof of the building 1, 3 is a water receiving tank provided on the surface of the ground, 4 is a water main, and the water main 4 has an intake pipe 6 provided with a water stop valve 5 in the middle. Is connected, and the other end of the water intake pipe 6 is open to the water receiving tank 3. 7
Is a water pump. The water pump 7 sends water in the water receiving tank 3 to the elevated water tank 2 through the conduit 8 and the first standing pipe 9. Reference numeral 10 denotes a check valve provided at a lower portion of the first standing pipe 9, which is opened when the pump 7 is operating and closed when the pump 7 is stopped. Reference numeral 12 denotes a water pipe on each floor connected to a second standing pipe 11 running through the building 1.
2 are each provided with a tap 13. Reference numeral 14 denotes a switching valve provided in the conduit 8. The switching valve 14 is connected to an auxiliary water supply pipe 15, and a water tap 16 is provided at the other end of the auxiliary water supply pipe 15.

If the pump 7 stops due to a power failure or a failure, the water supply to the elevated water tank 2 stops, and the water is cut off after a lapse of time. However, at this time, the switching valve 14 is switched to guide the water in the water receiving tank 3 to the water supply pipe 15. Therefore, the resident
Water can be drawn from the tap faucet 16, and drinking water can be reliably secured.

In FIG. 2, the same reference numerals as those in FIG. 1 denote the same components. Reference numeral 17 denotes a pressurized tank, which directly supplies the water pressurized in the pressurized tank 17 to the second vertical pipe 11 to supply water to each floor. Reference numeral 18 denotes an air chamber which releases the pressure when the pressure in the second standing pipe 11 becomes higher than necessary.

In the case of FIG. 2 as well, when the pressurizing pump 19 and the pressurizing tank 17 are stopped due to a power failure or failure, the switching valve 14 guides the water in the conduit 8 to the faucet 16 via the auxiliary water supply pipe 15. Residents can draw water through the tap 16.

[0017]

According to the present invention, it is possible to secure necessary drinking water for the occupants even if the water pump or the pressurizing pump stops due to a power failure or failure.
