It is arranged in. Reference numeral 25 denotes a transmission rod attached to the sub-valve 24s, and reference numeral 26 denotes a float attached to the lower end of the transmission rod 25.

[0017] In addition, each part is watertight so that water does not leak. A water pipe or a water pipe connected to the water pipe 16C passes through the right side of the front panel 23F. The front panel 23F is detachable so that the front panel 23F can be detached from the side wall 2S (the vertical flange portion 2sf of the rectangular panel 2s) without removing a water pipe or the like.

[0018] Next, a description will be given of the operation. First, when the water use location is in the water use state, the control device 21 drives and controls, for example, the submersible pump 15A mounted on the mounting flange 14A based on the pressure detection signal from the pressure sensor 20. When the submersible pump 15A operates, the water sent from the submersible pump 15A to the drain pipe 16A is supplied to the gate valve 1A.
7A, it flows out to a flush pipe or a drain pipe connected to the flush pipe 16C via the check valve 18A and the flush pipe 16C.

[0019] Thus, until the water-use state,
The water in the water receiving tank 1 is sent to the water use point by the submersible pump 15A. When the water level of the water receiving tank 1 falls and the float 26 descends to a predetermined position, the auxiliary valve 24s
Is opened, water is supplied from the water supply pipe 11 via the bypass pipe 24b into the water receiving tank 1 from the sub-valve 24s, so that the main valve 24m is opened, and the main valve 24m is also supplied from the water supply pipe 11.
The water is supplied to the water receiving tank 1 through m.

By supplying water to the water receiving tank 1 in this manner, the float 26 rises as the water level rises, and the sub valve 2
When 4s is closed, the main valve 24m is also closed, so that the water supply to the water receiving tank 1 is stopped. When water is supplied, the control device 21 drives and controls the submersible pump 15A based on the pressure detection signal, and controls the water pressure to be constant. The heat generated by the operation of the control device 21 is generated by the side wall member 6.
The water is then conducted to the water in the water receiving tank 1, and is conveyed and radiated.

[0021] As described above, according to one embodiment of the present invention, the storage box 22 using the sidewall 2S of the water receiving tank 1
Within sterically and control device 21 located outside the water tank 1, and, since the Bian earnestly housing, it is possible to reduce the installation space. Doors 23Dl and 23Dr are provided, and the storage box 22, that is, the front panel 23F is provided.
Is detachable from the side wall 2S, the door 23
By opening Dl, 23Dr or by removing front panel 23F from side wall 2S, maintenance and inspection of control device 21, main valve 24m, etc. can be easily performed, and the maintenance and inspection locations are in storage box 22 and ceiling 2C. for limited to the sub-valve 24s, maintenance and inspection can be performed better work efficiency.

Furthermore, since the storage box 22 is in a closed state, even if the operation sound is generated by the control unit 21 is operated, operation sound will no longer leaks to the outside, preventing effect,
A soundproofing effect and a dustproofing effect can be obtained. In addition, since the heat generated by the operation of the control device 21 is transmitted to the water in the water receiving tank 1 via the side wall member 6 and is conveyed and radiated, the control device 21 does not deteriorate in function due to the heat. Works fine.

The inverter 21b can be cooled without attaching a cooling fin or a cooling fan to the heat generating portion of the inverter 21b.
1b can be reduced in cost and size. Further, the water supply pipe 11 is disposed in the water receiving tank 1 via the storage box 22, and the main valve 2 is connected to the water supply pipe 11 in the storage box 22.
4 m and the bypass pipe 24 b are also disposed in the protection pipe 13, so that measures for preventing freezing and cold protection of the water supply pipe 11 are reduced, and the main valve 24 m and the bypass are provided. Since measures for preventing freezing and preventing the cold from being applied to the tube 24b are not required, measures for preventing the freezing and for preventing the cold are simplified.

Further , since the water supply pipe 11 is disposed in the protection pipe 13 and the upper end of the protection pipe 13 protrudes above the full water level, even if the water supply pipe 11 in the protection pipe 13 is damaged, the water supply pipe 11 is damaged. ,
Since the water in the water receiving tank 1 does not flow back to the water supply pipe 11, there is no fear that the water in the water supply pipe 11 is contaminated with the water in the water receiving tank 1. Since the bypass pipe 24b is provided in the protective pipe 13 and the components provided outside the water receiving tank 1 are stored in the storage box 22, those which are visible outside the water receiving tank 1 are stored in the storage box 22. 22 only, and the appearance of the water receiving tank 1 is clear.

In the above embodiment, the control device 21 is cooled by using the side wall member 6. However, if the back panel 23B, that is, the rectangular panel 2S is a good conductor, the side wall member 6 is not necessarily used. No need. And
The booster has been described as an example in which the submersible pumps 15A and 15B are used. However, the liquid handled around the motor unit in a rod shape proposed by the present applicant in Japanese Patent Application Nos. 5-47104 and 5-47105 is disclosed. A land pump configured to circulate and cool the motor unit may be housed in the storage box 22 as a booster.

In this case, even if the operation sound is generated by the operation of the land pump, the operation sound is not leaked to the outside, so that the sound insulation effect and the dust prevention effect for the land pump can be obtained, and the land pump can be closed. Since it is covered and is not directly exposed to the outside air, it is possible to obtain an antifreezing effect and a cold protection effect. Further, the storage box 22 shields the sound of operation of a land pump or the like from leaking to the outside, but by installing soundproofing materials on the entire inner surface of the storage box 22, a compact and more effective soundproofing measure can be easily taken. be able to.

[0027]

As described above, according to the present invention, the water receiving
While installing the main valve in the water supply pipe located outside the tank ,
The sub-valve was installed on the ceiling of the receiving tank, so maintenance and inspection of the main and sub-valves could be easily performed, and the number of maintenance and inspection points was limited .
Because, perform maintenance and inspection work efficiently. And the water pipe
Is placed inside the protective tube, and the upper end of the protective tube projects above the full water level, so that even if the water supply tube in the protective tube is damaged, the water in the receiving tank will flow back to the water supply tube. There is no need to worry about contamination of the water supply pipe with water from the receiving tank. Further
In addition, since the bypass pipe is located inside the protection pipe ,
Eliminates the need for anti-freeze and cold protection measures on the Ipass tube
Therefore, freeze prevention measures and cold protection measures are simplified,
Also, the bypass pipe was not exposed outside the receiving tank.
Because, the appearance of the water receiving tank to clean.
