As shown in the figure, the vertical hole 16 of the valve 2 is the second connection port 13 of the valve box 1.
The valve 2 is rotated so as to come to the position corresponding to. In this state, the holes 15 and 16 of the valve 2 communicate the water passage 5 and the second connection port 13 in this state. Further, the first connection port 12 and the water outlet 11 communicate with each other via the internal space of the valve chamber 4. Tap water is supplied from the water passage 5 of the valve box 1 to the lateral hole 15 of the valve 2 as in the case described above.
And flows through the vertical hole 16 to reach the second connection port 13 of the valve box 1. Tap water enters the inside from the water outlet 24 of the case 25 of the water filter 22 through the second connection port 13 through the hose, and the filter medium.
It passes through 26 and flows out from the water inlet 23. As a result, the filter medium 26 is backwashed to remove the deposits adhering to the filter medium 26, and then flushed with the tap water. Tap water flows from the first connection port 12 through the hose into the valve chamber 2 of the valve box 1,
Furthermore, it is sent out through the water outlet 11.
なお、弁２の縦孔16の開口と弁箱１の各口11〜13との合
わせる面積を調整すると、水道水の流量を調整できる。The flow rate of tap water can be adjusted by adjusting the area where the opening of the vertical hole 16 of the valve 2 and the openings 11 to 13 of the valve box 1 are adjusted.
なお、弁２を、縦孔16が各口11〜13以外の弁室４の壁に
位置にするように回動すれば、縦孔16から水道水が外部
に流れ出ることを停止する事ができる。If the valve 2 is rotated so that the vertical hole 16 is located on the wall of the valve chamber 4 other than the ports 11 to 13, it is possible to stop the tap water from flowing out from the vertical hole 16. .
