Abstract

PURPOSE: In a ball valve equipped with a Scotch yoke type actuator, to pivot a valve body by means of a smaller output actuator, by substantially corresponding the output torque distribution of said actuator to the torque distribution of the ball valve.
CONSTITUTION: When cylinders 12, 13 are actuated to cause a pin 21 to move leftward, a pivotal shaft 3 is turned counterclockwise together with an arm 15 through the pin 21 and a long hole 16, so that a ball-shaped valve body is shifted to an opening position. The deflection angle of the arm 15, where the valve is in the completely-closed position, with respect to a plane perpendicular to the axial direction of rods 18, 19 i.e., to the reciprocating direction of the pin 21 and containing the pivotal shaft 3 is greater than that of the arm 15, where the valve is the completely-open position, with respect to said plane. The wider the deflection angle, the greater the output torque. Thus, an actuator has a wider output torque distribution when the valve is in the completely-closed position than when it is in the completely- open position.
