Abstract

Described below is an improvement that has been added to the Multi- Cycle Ball Activated Circulation Valve previously disclosed in US 2011/0315389, US 2011/0315390, and US Patent 8,118,101. The improvement is focused on the ball retention capability of the Ball diverter tube used in the Multi-Cycle Ball Activated Circulation valve. Using this invention, the ball diverter tube inlet will always be oriented towards the bottom of the tube. This ensures that the easiest possible position is attained using gravity. The current Multi-Cycle Ball Activated Circulation Valve is using a helical shape ball diverter tube that has a 45 degrees inlet. Balls of different sizes are caught at the inlet and travel on a ramp till they reach a helical pathway and stored. It was noticed that balls are easily retained when the opening or inlet is on the bottom of the ball diverter tube making it easier for the balls to travel with gravity and pressure from the fluid. As such, the inlet of the ball diverter tube should be designed so that it is always on the bottom side regardless of the orientation of the tool. This could be done by using two bearings on each side of the ball diverter tube for free/low friction rotation. In addition, the ball diverter tube will be fitted with a weight taking the shape of a fly wheel that will always assist the ball diverter tube to rotate till the part is in equilibrium. The weight on the ball diverter tube will be always on the side of the ball diverter tube. This will allow the inlet to be at the bottom of the ball diverter tube during operation in the horizontal sections. This feature is not important when drilling or operating in vertical sections since gravity will always be assisting the balls to go through the ball diverter tube regardless of the orientation of the ball diverter tube inlet. For the fly wheel weight to be effective in turning the ball diverter tube to the desired orientation, the ball diverter tube should be machined out of lighter material. This will ensure that the fly wheel can easily overcome the weight of the ball diverter tube to turn it.
