This utility model is very convenient for replacing and cleaning the inside of the ball valve by providing a ball valve holder, a connecting end protrusion and a fixed end groove, which can extend the service life of the ball valve. The internal flow ball valve is welded together with the handle and will not be damaged during use. In addition, a control rod sealing ring is provided at the control rod jack and the control rod connection, which has better sealing performance. When it is necessary to clean the internal impurities, the ball valve holder is directly unscrewed, and the connecting end protrusion and the fixed end groove are separated to clean the inside.

The internal fluid first passes through the connecting groove 201 and then passes through the circulation groove 203, thereby reducing the impact force of the internal fluid and reducing damage to the valve body 1. In addition, the connecting groove 201 at any end can be blocked, so that the valve body 1 can be connected to different numbers of connecting pipes 204, which is more convenient.

[0033] Specifically, Figure 4 As shown, the rotating assembly 3 includes a rotating groove 301, a rotating rod 302, a rotating ball head 303 and a connecting hole 304. The rotating groove 301 is opened on the inner side of the top of the valve body 1, the rotating rod 302 is rotatably set inside the rotating groove 301, the rotating ball head 303 is fixedly set at the bottom end of the rotating rod 302, and the connecting hole 304 is opened on the surface of the rotating ball head 303.
