Claims (1)
る流量調整弁であって、弁棒に直結した２つのダイアフ
ラムを備え、１つのダイアフラムは操作空気圧を受圧す
る受圧面をなし、弁を開く方向に受圧し、使のダイアフ
ラムは調整弁出口通路の流体の圧力を受圧する受圧面を
なし、弁を閉じる方向に受圧し、２つのダイアフラムの
受圧面積が互いに異なることを特徴とする流量調整弁。The flow rate regulating valve is a diaphragm valve that controls the flow rate of fluid using operating air pressure, and is equipped with two diaphragms directly connected to the valve stem, one diaphragm serving as a pressure receiving surface that receives operating air pressure, and the flow rate regulating valve is a diaphragm valve that controls the flow rate of fluid using operating air pressure. A flow rate regulating valve, characterized in that the second diaphragm forms a pressure receiving surface that receives the pressure of the fluid in the regulating valve outlet passage, receives pressure in a direction to close the valve, and the pressure receiving areas of the two diaphragms are different from each other.
