Abstract

The application provides a ball valve which is simple in structure, convenient to open and close and capable of preventing others from opening the ball valve. The ball valve comprises a valve body, a valve cover, water inlet and outlet channels, a ball plate and a valve rod. The valve cover is provided with a sealing box. The valve rod is provided with a driving gear at the end thereof, and the driving gear is located in the sealing box. A first gear row is slidably arranged at the bottom of the sealing box. A sliding rod is slidably arranged above the first gear row in the sealing box. A second gear row is formed in the sliding rod. The end of the sliding rod is further provided with a third gear row which is engaged with the driving gear. A rotating gear which drives the sliding rod and the first gear row to move is engaged between the first gear row and the second gear row. The sealing box is provided with a pushing rod which is used for driving the rotating gear to move. The pushing rod is arranged on the sealing box. The sealing box is provided with a limiting mechanism which can limit the sliding of the first gear row, so that the rotating gear drives the sliding rod to slide, and the third gear row is engaged with the driving gear.
