Patent

CA 2486008

A valve has a valuing element which is rotatably fitted within a valve body. This valuing element of the valve is joined by a stem or shaft portion which extends out of the valve body to interact with an actuator and transmit torque to the valuing element. In plug valves, pressure needs to be also applied to the valuing element to insure a proper closure. The invention relates to a mechanism to adjustably seal the stem/body interface using only one screw that is positioned on the front of the valve cover for easy access. The force generated by the screw is transposed into a vertical force and a horizontal force by a cam. The multiple faces of the cam are used to transmit the force vertically and horizontally and will maintain the mechanism in a straight position.
