んとして多いという問題点が指摘されてい−る。Conventionally, a single butterfly valve was used to stop the water flowing through the pipe, and the amount of water was changed by varying the opening degree of the butterfly valve. However, if the butterfly valve is large, it not only takes time to control the valve, but also requires a lot of work. Therefore, in recent years, a two-shaft type butterfly valve for the main and sub-valves has been proposed in Utility Model Publication No. 48-30975 and Utility Model Publication No. 48-25327, which open and close both the main and auxiliary valves, respectively, depending on the state of water usage. However, if you try to flow a very small amount of water at night, the direct product of the flow rate is so large that it is difficult to use the hub, and you have to leave the sub valve half open, which makes the flow not smooth and noisy. It has been pointed out that problems such as the occurrence of gas leakage and the amount of work involved in opening and closing the sub-valves are still large.
そこで本発明は、夜間に利用する水量に合わせた小流量
の水をスムースに供給できるバタフライバルブを提供す

The three sub-valve shafts are extended into the gear case at the top of the valve housing.
Each of them is independently driven to rotate by a nine-rotation drive mechanism.
