When the Unlimited-Circulation Bypass Valve (UCBV) is descended with the drill string, the bypass hole is closed. When the bypass hole needs to be opened, put a ball in the wellhead, the ball will fall to the slide sleeve due to its own gravity, and then open the pump to give a certain pressure (greater than the shear pressure of the ball), the ball will push the slide sleeve to rotate down, the ball is compressed through the inner hole of the slide sleeve, falling on the lower ball seat, and at the same time the slide sleeve is unlocked, the spring pushes the slide sleeve to rotate up, and then the bypass hole opens;
when the bypass hole is closed, another ball is put in the wellhead, the ball will fall to the slide sleeve due to its own gravity, and then the pump gives a certain pressure (greater than the shear pressure of the ball), the ball will push the slide sleeve to rotate down, the ball is compressed through the inner hole of the slide sleeve, and the ball on the lower ball seat is hit into the collection basket, and the slide sleeve is locked, the spring is compressed, after which the bypass hole closes.
Repeat the above process to achieve the purpose of multiple switches.
