ねじ杆と螺合したねじ筒を軸方向に移動して弁体を弁座
に接離させるものにおいて、上記操作ねじ杆およびねじ
筒の一方のねじ溝条にその接線方向と垂直な当接面を有
するストッパ部を設けるとともに、他方のねじ突条の端
部にその接線方向と垂直な当接面を形成し、上記弁体が
全閉の一状態で上記ストッパ部の当接面と上記ねじ突条
の当接面を当接させて、操作ねじ杆の回動を阻止するこ
とを特徴とするバルブの弁体駆動機構。In a device that moves the operating screw rod or the threaded cylinder threadedly engaged with the operating screw rod in the axial direction by rotating the operating screw rod to move the valve body toward and away from the valve seat, one of the operating screw rod and the screw cylinder. A stopper portion having a contact surface perpendicular to the tangential direction is provided on the thread groove, and an abutment surface perpendicular to the tangential direction is formed at the end of the other thread protrusion, so that the valve body is fully closed. A valve body drive mechanism for a valve, characterized in that in one state, a contact surface of the stopper portion and a contact surface of the threaded protrusion are brought into contact with each other to prevent rotation of the operating screw rod.
