[0028] In use, the screw 8 is positioned by setting the second lug 7;

[0029] A screw 8 is installed between the first ear seat 6 and the second ear seat 7. The two ends of the screw 8 pass through the first ear seat 6 and the second ear seat 7 respectively and are threaded with a locking nut 9.

[0030] In use, the ball valve can be disassembled and maintained by tightening the locking nut 9 and removing it from both ends of the screw 8;

[0031] A second valve cover 3 is installed on the outer wall of the other side of the valve body 1. A ball core 16 is rotatably installed inside the valve body 1. The ball core 16 has a ball groove 1601 inside. Sealing rings 17 are installed on the inner walls of both sides of the valve body 1. The inner wall of the sealing ring 17 contacts the outer wall of the ball core 16. A hollow seat 10 is provided at the center of the top of the valve body 1.
