The on-off valve 7 described above may be the one described in Japanese Utility Model Laid-Open No. 1-131072 proposed by the present applicant. As shown in FIG. 4, this has a cylindrical valve chamber 22 provided with end plates 19, 20 at both ends and an inlet opening 21 in a peripheral wall, and a valve seat tube 23 is provided concentrically on the end plate 19, and the other end is provided. From the center of the end plate 20, a thin hollow cylinder 24 having an external thread on the outer periphery protrudes.
The hollow cylinder 24 has a handle 25 at the outer end, and a rotary shaft 26 whose tip reaches the end plate 19 penetrates. The rotary shaft 26 has a male screw 27 at a portion protruding into the cylindrical valve chamber 22. The center of a valve plate 28 that can close the end of the valve seat cylinder 23 protruding into the cylindrical valve chamber 22 is provided with the male screw 27.
Is fixed to a female screw cylinder 29 having a female screw on the inner periphery which is screw-engaged.

With the on-off valve 7, the extension pipe 5 and the outer wall a of the room A
In order to connect the extension pipe 6 and the outer wall b of the chamber B, respectively, a hole through which the hollow cylinder 24 passes is formed in a portion of the outer walls a and b facing the extension pipes 5 and 6, and the hollow cylinder 24 fitted with packing is connected. protrudes out through the chamber to the bore, to fix the outer wall a is fitted a nut 30 to the hollow cylinder 24 from the outside, the outer surface of b a cylindrical valve chamber 22 by attaching tighten the outer wall a, on the inner surface of b, Hollow cylinder 2
Sealing is performed by compressing the packing fitted in 4 between the end plate 20 and the inner surfaces of the outer walls a and b . Then, the rotary shaft 26 fitted with the cap nut 31 screwed into the external thread on the outer periphery of the hollow cylinder 24
Is inserted into the hollow cylinder 24 from outside, and the rotation shaft 26 is inserted into the female screw cylinder 29 at the center of the valve plate 28 placed in the cylindrical valve chamber 22.
Of the rotary shaft 26 into the end plate 19.
, And in this state, the cap nut 31 is
Lightly tighten with the outer periphery of the male screw 4, the end face of the hollow cylinder 24, scissors lightly flange 26 'provided on the rotary shaft 26 between the cap nut 31, the rotary shaft 26 from moving axially blocking I do. The handle 2 is attached to the outer end of the rotating shaft 26.
5 is fixed, and the valve plate 28 has an inlet opening 21 of the cylindrical valve chamber 22.
The stopper 32 which abuts on the edge 21 ′ of the frame is fixed radially.

[0014] Thus the outer wall a, After the switch valve 7 set seen standing <br/> have while fixing the b, the tip of the valve seat tube 2 of each extension tube 5, 6
3 and connected by screwing.

The on-off valve 7 is opened (solid line in FIG. 4) when the valve plate 28 is separated from the valve seat tube 23, and the valve plate 28 is pressed against the valve seat tube 23 to close the valve seat tube 23 . When the valve closes (Fig. 4
(Broken line). To close the opened on-off valve 7, the handle 25 turns the rotary shaft 26 in one direction from outside the tank main body 1 . As a result, the valve plate 28 initially rotates slightly together with the rotary shaft 26, but the stopper 32 is moved to one edge 2 of the inlet opening 21.
When it comes into contact with 1 ', it cannot rotate thereafter. Rotating shaft 26
Is continued, the female screw cylinder 29 fixed to the center of the valve plate 28 is screw-engaged with the male screw 27 of the rotary shaft 26 , so that the valve plate 28 and the female screw cylinder 29 are integrated into the cylindrical valve chamber 22.

At 5, the rotating shaft 26 is turned in the opposite direction. Thereby, the valve plate 2
8 initially rotates slightly together with the rotating shaft 26 , but the stopper 3
2 cannot rotate again due to contact with the opposite edge 21 ′ of the inlet opening 21, and moves in the direction away from the valve seat cylinder 23 in the cylindrical valve chamber 22 for the same reason by the subsequent rotation of the rotating shaft 26 , and opens. Give a valve.

In order to connect the chambers A and B to each other and use them in the same manner as a one-tank type water receiving tank, an open / close valve 7 connecting the extension pipe 5 in the chamber A and the outer wall a and the extension pipe 6 in the chamber B are used. The on-off valves 7 connected to the outer wall b are both opened. Thereby, the chamber A and the chamber B communicate with each other through the communication pipe 3 laid in the water tank main body 1 including the extension pipes 5 and 6 and the through pipe 4 connecting the extension pipes 5 and 6 .
The water levels in both the A and B chambers and the sub tank 11 are the same. When the water in both the chambers A and B is supplied to the outside and the water level in the sub-tank 11 falls accordingly , the float 10 'of the ball tap 10 also falls. When the float 10 ' descends to a predetermined position , the ball tap 10 opens, and tap water reaching the ball tap 10 through the main valve 9 and the pilot pipe 13 closed from the upstream pipe 12' of the water inlet pipe 12 becomes small. It is supplied to the sub tank 11 at a flow rate. When the supply of water by the ball tap 10 starts, the pressure changes inside the main valve 9, the main valve 9 is fully opened, and then the main valve 9 enters the water inlet pipe.
A large flow of tap water is supplied to the sub-tank 11 through the downstream pipe 12 ″.

When the tap water is replenished into the sub-tank 11 and the water levels in both the A and B chambers and the sub-tank 11 rise, the float 10 'of the ball tap 10 also rises, and when the water level comes to just before the upper limit, the ball tap 10 closes. This causes a reverse pressure change inside the main valve 9 and eventually the main valve 9
9 is also closed and the supply of water is completed. Even if the water level reaches the upper limit due to the failure of the constant water level valve 8, the supply of water does not stop. If the water exceeds the upper limit water level, the overflow pipe 18 drains out to prevent the water level from rising further. . In order to prevent the float 10 'of the ball tap 10 from violently moving with the replenished water during the replenishing of water and causing a failure, the tip of the downstream pipe 12 "of the water inlet pipe 12 which has entered the sub tank 11 is directed downward. ,
It is preferable to protrude inside the supply pipe 15 and place it.

When checking and cleaning the inside of the room A, the on-off valve 7 connecting the extension pipe 5 and the outer wall a in the room A is closed. As a result, the inside of the communication pipe 3 communicates with the room B, but is isolated from the room A, so that the water in the room A can be drained from the drain so that the room can be inspected and cleaned. In the meantime, outside water is supplied from the room B, and when the water level in the room B falls, tap water is supplied to the room B via the sub tank 11 and the supply pipe 15 by the constant water level valve 8 as described above, and the water level is recovered. I do.

When the inspection and cleaning of the room A are completed, the on-off valve 7 connecting the extension pipe 5 and the outer wall a in the room A is opened.
Raise the water level in both rooms to the upper limit. The extension pipe 6 in the room B
By closing the on-off valve 7 connecting the and the outer wall b,
Similarly, the inspection and cleaning of the room B can be performed. During this time, the water in the room A is supplied to the outside, and when the water level in the room decreases, the tap water is supplied to recover the water level.

As described above, the penetration pipe 4 penetrating the partition wall 2,
A communication pipe 3 comprising extension pipes 5 and 6 connected to respective ends thereof, and two on-off valves 7 and 7 for connecting the extension pipes 5 and 6 with outer walls a and b of both the A and B chambers. Thus, water can be supplied to both the chambers A and B, and water can be supplied to the chambers A and B individually.

The constant water level valve 8 automatically starts the supply of tap water when the water level in the sub tank 11 drops and stops the supply when the water level recovers. To monitor for abnormalities where water is not being replenished,
Electrodes are used to monitor abnormalities that water supply does not stop even when the water level recovers. The electrodes 33 may be erected from the ceiling walls of the rooms A and B, but two sets of the room A and the room B are required. In order to complete this operation, the inside of the supply pipe 15 is divided into two by a vertical partition wall 15 ', and the water inlet pipe 12 is inserted into one of the divisions from above, and the other is divided. The electrode 33 may be vertically installed from above (FIG. 6), or the communication pipe 3 (the penetration pipe 4 may be extended
Or, it may be 6. A), the auxiliary pipe 34 whose lower end communicates with A,
