Abstract

Invention utilizes an interface between an actuating member and ball that provides a larger force input to open/close a ball valve than what is currently available Valve designs have profiles that control the opening and closing aspect of the valve on the ball. There are Y-slots, milled grooves and the like that rely on an actuating member with a pin or some member to move past the ball. As this member moves past the ball there is a force imparted to the ball which will open/close it. This invention puts pins directly on the ball. The profile that controls the opening and closing of the ball is machined onto the actuation member that moves relative to the ball. The profile can be tailored in such a way that a large tangential force can be used to initiate opening. The forces imparted to the ball can be 2-3 times more than what is being imparted to the valve to actuate it open and close.

Force multiplier used to actuate a ball valve

Valve designs have profiles that control the opening and closing aspect of the valve on the ball. There are Y-slots, milled grooves and the like that rely on an actuating member with a pin or some member to move past the ball. As this member moves past the ball there is a force imparted to the ball which will open/close it. This invention puts pins directly on the ball. The profile that controls the opening and closing of the ball is machined onto the actuation member that moves relative to the ball. The profile can be tailored in such a way that a large tangential force can be used to initiate opening. The forces imparted to the ball can be 2-3 times more than what is being imparted to the valve to actuate it open and close.
