Therefore, the development of an easy-to-disassemble ball valve has important practical significance.

[0003] A patent document with publication number CN214466273U in the prior art provides a ball valve, which utilizes a combination of three components: a valve body assembly, a valve core assembly, and a valve stem assembly. A full-diameter flow channel is provided through the valve cover and the valve body. The valve stem is controlled by a wrench on the top for easy rotation. The valve stem is connected to the ball, and a ball groove is provided on the circumferential side wall of the ball for easy control of water flow.

[0004] Although the device has many beneficial effects, the following problems still exist: the ball valve is composed of a combination of various different parts, and because the conventional valve body and valve cover are connected by threaded connection, they will vibrate during movement after long-term use, thereby generating a gap; secondly, the existing conventional sealing structure has a single structural combination, which affects the sealing effect.
