Abstract
A ball valve having an actuator of blow out prevention includes a valve body, actuator, and a ball. The valve body has a valve chamber inside thereof and a passageway, top bore, bottom bore extending from the valve chamber. The actuator has a connection portion penetrating through the top bore to the valve chamber, the connection portion has a round groove and a C-shaped buckle. The actuator serves to be rotated by an external driver. The ball inside the valve chamber serves to control the flow of the valve chamber. The ball has a connection hole engaging the connection portion of the actuator. The C-shaped buckle retains the actuator connected to the ball through buckling the round groove of the connection portion receiving inside the connection hole of the ball so that the actuator will not blow out by the pressure of the valve during a damage or maintenance.
