量変化せしめることを特徴とする流量調整弁。A water passage opening on the inner wall surface of the valve box is formed in a square or diamond shape, and an opening with the same shape and area as the water passage opening, or a V-shaped notch corresponding to half thereof, is provided in the valve body, and the valve body is moved. As the valve moves, the opening or notch moves along the water passage opening of the valve seat, keeping the shape of the water passage opening similar to the shape when it is fully open, and the change in opening area is controlled by the valve small size as the valve body moves. A flow rate regulating valve characterized in that the flow rate is changed approximately in proportion to the movement of the valve body by having a small opening at the opening portion and a large opening at the large valve opening portion.
