Abstract

PURPOSE:To enable water to be supplied into both chambers A, B, or one chamber A or B, with one water-filling pipe by dividing the internal section of a water tank main-body into the chambers A, B, with a parting wall, and by setting a sub-tank outside the chambers, to joint the sub-tank and the chambers A, B to each other with supplying pipes. CONSTITUTION:A water tank main-body 1 is divided into a chamber A and a chamber B, with a parting wall 2. After that, a sub-tank 4 for water to be supplied into a by a water-filling pipe 3 is set outside said chambers. Then, the bottom of the sub-tank 4 and the chambers A, B are connected to each other with supplying pipes 5A, 5B, and an opening or closing valve 6 to be operated outside the tank is set. Besides, the sub-tank 4 is provided with a water overflowing pipe 7 for discharging water to an external section by permitting supplied water to overflow an upper limit water level. In its case, when the opening or closing valve 6 is opened, then the chambers A, B communicate with the internal section of the sub-tank 4, and so water supplied into the sub-tank 4 by the water filling pipe 3 and a water level setting valve 8 is supplied into the chambers A, B respectively, by the supplying pipes 5A, 5B. As a result, the water can be supplied into both the chambers A, B, or one chamber A or B, and a double piping or device can be avoided.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] This invention relates to a water replenishing device for replenishing water to both chambers A and B of a two-tank water tank, in which the interior of the tank body is divided into chamber A and chamber B by a partition wall. .

0002

BACKGROUND OF THE INVENTION Such two-tank water storage tanks have been known for some time. A two-tank type water tank is used in the same way as a single-tank type water tank, with the separated chambers A and B connected at all times through a communication pipe piped outside the tank body, and the interior must be inspected and cleaned. In such a case, close the on-off valve installed in the middle of the communication pipe to cut off communication between chambers A and B. For example, empty the water in chamber A and perform inspection and cleaning, while supplying water in chamber B during that time. At the same time, when the amount of water decreases, water is replenished, and after checking and cleaning Room A, filling Room A with water, emptying the water in Room B and performing inspection and cleaning, while supplying water from Room A. At the same time, if the water level decreases, receive water supply, and after checking and cleaning room B, return to room B.
After filling the chamber with water, open the on-off valve to connect chambers A and B again. As a result, water can be supplied to either chamber A or B when inspecting or cleaning the inside of the tank, and interruption of water supply can be avoided.

0003

[Problem to be Solved by the Invention] In this way, when one of rooms A and B is being inspected and cleaned, water is supplied from the other room, and when the amount of water decreases, the water is replenished. It becomes necessary to supply water to room B and room B through separate water inlet pipes, and the installation of two sets of water supply systems causes problems such as increased cost and increased labor.

0004

[Means for Solving the Problems] Therefore, the present invention has made it possible to supply water to both chambers A and B with one water inlet pipe, and to supply water to both chambers A and B. In a two-tank type water storage tank which is divided into room A and room B by a partition wall, a sub-tank is installed above the outside of the tank body to which water is supplied through an inlet pipe, and the inside of the sub-tank and room A, and B
The interiors of the chambers were connected by supply pipes, and each supply pipe was provided with an on-off valve.

[0005]

[Embodiments] In each of the illustrated embodiments, 1 is an aquarium main body;
The interior of the room is divided by a partition wall 2 into room A and room B, each having approximately the same capacity. At the top of the outer wall of the aquarium body 1 is a water inlet pipe 3.
A sub-tank 4 is installed where water is replenished, and supply pipes 5A are connected to the bottom of the sub-tank, the inside of room A, and the inside of room B, respectively.
, 5B. Each supply pipe 5A, 5B is provided with an on-off valve 6 that is operated outside the tank.

When the on-off valves 6 of the supply pipes 5A and 5B are opened, the inside of the A chamber and the inside of the B chamber are respectively communicated with the inside of the sub-tank 4, and the water level is the same, so the sub-tank 4 has an upper limit. An overflow pipe 7 is provided for overflowing and draining water replenished beyond the water level to the outside. Furthermore, this overflow pipe 7
may be provided in room A and room B, respectively, instead of in the sub-tank.

[0007] The water tank is installed above ground or underground,
There are water tanks that are replenished with tap water via an inlet pipe and a fixed water level valve, and elevated water tanks that are installed on the roof of a building and are replenished with water from the tank pumped up by a pump. However, the present invention can be implemented in both the water tank and the elevated water tank.

[0008] Fixed water level valves used in water receiving tanks include those that consist of a main valve and a ball tap, and those that do not have a ball tap but have a built-in float valve that moves up and down depending on the rise and fall of the water surface. When the water drops, it opens and water begins to be replenished.
As a result, when the water level rises to a predetermined height, the float valve also rises and closes, stopping water replenishment.There is a single direct type constant water level valve, such as the Keihin High Flow constant water level valve (trade name of Keihin Seiki Seisakusho Co., Ltd.).

FIG. 1 shows an embodiment of a water tank using a direct type constant water level valve 8, in which an inlet pipe 3 for introducing tap water penetrates the side wall of a sub-tank 4 and enters the tank, and is connected to its downwardly bent lower end. A direct type constant water level valve 8 is installed.

When the on-off valves 6 of the supply pipes 5A and 5B are opened in FIG. is supplied to room A and room B through supply pipes 5A and 5B, respectively.
As with a single-tank type aquarium, water from rooms A and B can be supplied outside. In this case, since the insides of chambers A and B are in communication with the inside of the subtank, the water levels in both chambers A and B and in the subtank are the same.

Water from rooms A and B is supplied outside, and when the water level in the sub-tank drops, the constant water level valve 8 opens, and tap water is supplied into the sub-tank 4 via the water inlet pipe 3 and the constant water level valve 8. This water is supplied to both chambers A and B through supply pipes 5A and 5B. When the water level recovers, the direct type constant water level valve 8 closes and water supply stops.

When inspecting and cleaning the inside of room A, the on-off valve 6 of the supply pipe 5A that replenishes water from the sub-tank to room A is closed. This isolates Room A from the sub-tank, allowing the water in Room A to be drained from the drain to allow inspection and cleaning of the room. During this time, water is supplied to the outside from room B. When the water level in room B and the sub-tank drops, the constant water level valve 8 opens and supplies tap water to the sub-tank. When the water level in the sub-tank and room B recovers, the constant water level valve 8 opens. will close and supply will stop.

[0013] After checking and cleaning the room A, open the supply pipe 5A.
The on-off valve 6 is opened, and the water levels in both chambers A and B are restored using the constant water level valve 8. Then, by closing the on-off valve 6 of the supply pipe 5B to room B, the inside of room B can be inspected and cleaned in the same way.During that time, the water in room A is supplied outside, and when the water level in the room and sub-tank drops, Tap water is supplied through the constant water level valve 8 to restore the water level.

In this way, one water inlet pipe 3 is opened by operating the on-off valves 6 of the supply pipe 5A to room A and the supply pipe 5B to room B.
With the constant water level valve 8, water can be supplied to both chambers A and B, and water can be supplied to chambers A and B individually.

FIG. 2 shows an embodiment of a water tank using a constant water level valve 9 consisting of a main valve 10 and a ball tap 11.
A ball tap 11 is connected to the outside of the water tank body in the middle of the water inlet pipe 3 that replenishes the inside of the sub-tank 4 with tap water, and a ball tap 11 is provided at the tip of the pilot pipe 12 that enters the inside of the sub-tank 4 from the main valve 10. It is provided.

The supply pipes 5A and 5B may be lowered from the bottom of the sub-tank and connected to the inside of chamber A and the inside of chamber B, as in the embodiment of FIG. 1, but in this embodiment, the supply pipes 5A and 5B are Only the supply pipe 5A is lowered and communicates with the inside of the A room, and the supply pipe 5B having an on-off valve 6 is connected to the middle of the supply pipe 5A and communicates with the inside of the B room. Therefore, the on-off valve 6 of the supply pipe 5A is provided downstream of the connection part of the supply pipe 5B.

Since the supply pipe 5B communicates with the inside of the sub-tank 4 via the upstream part of the supply pipe 5A, in this embodiment as well, when the on-off valves 6, 6 of both pipes are opened, both chambers A and B, The water levels in the sub-tank 4 and the sub-tank 4 become the same, and the water in chambers A and B can be supplied to the outside in the same way as in a single-tank type aquarium.

When the water in chambers A and B is supplied to the outside and the water level in the sub-tank decreases accordingly, the float 11' of the ball tap 11 also decreases. When the float descends, the ball tap 11 opens, and tap water that has reached the ball tap from the upstream pipe 3' of the water inlet pipe 3 through the closed main valve 10 and pilot pipe 12 is replenished into the sub tank at a small flow rate. When the water supply by the ball tap 11 starts, the pressure inside the main valve 10 changes, and the main valve 10 eventually opens fully, and tap water is supplied from the main valve to the sub tank at a large flow rate through the downstream pipe 3'' of the water inlet pipe. be done.

In this way, tap water is replenished into the sub-tank 11, and when the water level in both chambers A and B and the sub-tank rises, the float 11' of the ball tap also rises, and when the water level reaches just before the upper limit, the ball tap closes. An opposite pressure change occurs inside the main valve, and eventually the main valve closes and water supply stops.

By closing the on-off valve 6 of the supply pipe 5A, the inside of room A can be inspected and cleaned. During this time, water can be supplied from room B to the outside, and by closing the on-off valve 6 of the supply pipe 5B, the inside of room A can be inspected and cleaned. The inside of the room can be inspected and cleaned, and during that time water can be supplied from room A to the outside.

When using the constant water level valve 9 with a ball tap, in order to prevent the ball tap 11 from shaking due to tap water supplied to the sub-tank at a large flow rate through the downstream pipe 3' of the water inlet pipe and causing a malfunction, It is preferable that the lower end of the downstream pipe protrudes shallowly into the supply pipe 5A from above as shown in the figure, or that a partition 4' is provided inside the sub-tank to partially shield the space between the ball tap and the downstream pipe.

If the direct type constant water level valve 8 or the constant water level valve with ball tap 9 malfunctions and the water supply does not stop even after reaching the upper limit water level in the sub tank, the overflow pipe 7
Drain the replenished water outside.

In the case of an elevated water tank, the lower end of the water inlet pipe 3 is connected to the outlet of the pump that pumps up the water in the water receiving tank, and the water in chambers A and B is supplied outside to lower the water level in the sub-tank. Tara,
This is detected by the water level detection electrode installed vertically in each room, and the pump is operated to supply the water in the water tank to the sub-tank, replenishing rooms A and B, and when the water level has recovered, the same electrode is used to detect the water level. Detected and stops pump operation.

[0024] Even in the case of an elevated water tank, the supply pipe 5A
By closing the on-off valve 6 of the supply pipe 5B, room A can be inspected and cleaned. Meanwhile, water from room B is supplied outside, and by closing the on-off valve 6 of the supply pipe 5B, room B can be inspected and cleaned. During this time, water from Room A can be supplied outside.

[0025] Regardless of whether it is implemented in a water receiving tank or an elevated water tank, the upper wall of the sub tank 4 is made removable.
Place it so that the interior can be inspected and cleaned. In addition, there is a vent 14 on the upper wall of the sub-tank, similar to the upper wall of chambers A and B.
Install.

Furthermore, if the sub-tank is installed outside of both chambers A and B as shown in the figure, the length of the supply pipe can be shortened; however, the sub-tank is not limited to this.
It may be installed above the outside of the room.

[0027]

As is clear from the above, in the present invention, water is supplied to the sub-tank 4 provided outside the main body of the aquarium through the inlet pipe 3, and from the sub-tank the supply pipes 5A each having an on-off valve 6 are provided.
Since water is supplied to chambers A and B in the aquarium body at 5B and 5B, water can be supplied to both chambers A and B, chamber A alone, and chamber B alone. This eliminates the need for equipment and the complexity of double piping when sub-tanks are installed in both chambers A and B separately.

Furthermore, since the sub-tank 4 and the supply pipes 5A and 5B are attached outside the main body of the water tank, it is easy to install and an existing two-tank type water tank can be easily modified.

Furthermore, if the sub-tank is provided inside the aquarium main body, the water storage capacity of the aquarium will be reduced by the amount of the sub-tank, but in the present invention, the sub-tank is provided outside the aquarium main body, so the water storage capacity will not be reduced. Moreover, operation can be performed with only one valve.
