Abstract
The utility model relates to a one-piece internal threaded ball valve, which comprises a valve body, a ball valve spool, a valve seat, a ball valve spool operating component and a valve seat limiting device. A through cavity is formed on the valve body, and a first liquid inlet and a liquid outlet of the valve body are communicated with the through cavity. A passage communicating the first liquid inlet with the liquid outlet is formed in the ball valve spool disposed in the through cavity. The liquid outlet is round, and a rotation axis of the ball valve spool passes through a circle center of the liquid outlet. A second liquid inlet communicated with the through cavity is formed on the valve body further, the first liquid inlet and the second liquid inlet are symmetrically formed on two sides of the liquid outlet, and after the ball valve spool is rotated clockwise or anticlockwise for corresponding angles, the first liquid inlet is communicated with the liquid outlet through the passage or the second liquid inlet is communicated with the liquid outlet through the passage. The one-piece internal threaded ball valve can be used for occasions needing alternate control of opening and closing for the two liquid inlets.
