This water supply device uses a water pump to forcefully send water received in a water tank through an air supply tank to the pressure tank side, and at this time, the air in the air supply tank is also pushed into the pressure tank to achieve the desired water supply pressure. and the amount of air inside the tank. Air is sucked into the air supply tank by draining water in the air supply tank when the water pump is stopped.

間に排水の為の配管が必要であつた。(Problems to be Solved by the Invention) In the water supply device as described above, the water discharged from the air supply tank is usually drained into a side gutter or returned to the water receiving tank. For this reason, when draining water into the side ditch, a considerable amount of water must be discarded in order to secure the required amount of air in the air supply tank, and when returning to the water receiving tank, at least the air supply tank must be discarded. There was a constraint that it had to be installed at a higher position than the aquarium, and there was a problem that the height of the entire device could not be lowered. Additionally, in the case of rooftop installation, piping for drainage was required between the air supply tank and the water receiving tank.

Therefore, the installation height of the air replenishment tank is not limited due to drainage, and there is no longer a need for a long drain pipe between the air replenishment tank and the water receiving tank.

は給水弁である。(Example) An example of this invention will be described below with reference to the drawings. In the figure, 1 is the pressure tank, 2 is the air supply tank,
The upstream side of the air supply tank 2 and the pressure tank 1 are connected to the check valve 3
They are connected by a pipe 4 with an interposed pipe. On the downstream side of the air supply tank 2, a pipe 7 having a check valve 5 and a water pump 6 interposed therebetween is provided between it and a water receiving tank 8. Further, between the downstream side of the air supply tank 2 and the pressure tank 1, there is a line pump 9, a solenoid valve 10, and a check valve 1.
A pipe 12 with a pipe 1 interposed therein is provided. In the figure, 13 is a suction valve, 14 is a pressure switch, 15 is an electrode, 16
is the water supply valve.

水ポンプ６が停止する。 In the above embodiment, when the water pump 6 is started, water in the water tank 8 is sent to the pressure tank 1 side through the air supply tank 2 and the piping 4. At this time,
If there is air in the air supply tank 2, this air is also forced into the pressure tank 1 side together with water, and the inside of the pressure tank 1 is pressurized. When the pressure in the pressure tank 1 reaches a required pressure, the water pump 6 is stopped by a signal from the pressure switch 14.

Detects the water level in the pressure tank 1 and determines whether air supply is necessary or not. If air supply is necessary, the line pump 9 is activated when the water supply pump 6 is stopped.
The sequence is set up so that it starts. When the line pump 9 is started, the solenoid valve 10 is opened in synchronization with this, and the water remaining in the air supply tank 2 is pressurized into the pressure tank 1 through the piping 12, and at the same time, the water remaining in the air supply tank 2 is injected into the pressure tank 1. Outside air is sucked in through the valve 13 in preparation for the next push of air. still,
The startup time of the line pump 9 is controlled by a timer built into the sequence.
