[0025] The valve core assembly 2 includes a valve ball 21, a valve stem 22 and a handwheel 23. The valve ball 21 is rotatably connected to the regulating chamber 3. An inlet channel 6 is provided at the lower end of the valve ball 21, and an outlet channel 7 is provided through the side wall of the valve ball 21. The outlet channel 7 is used to communicate with the water outlet hole 5, and the middle part of the outlet channel 7 is connected to the inlet channel 6. The valve stem 22 is rotatably connected to the upper end of the angle valve body 1, and the lower end of the valve stem 22 is connected to the valve ball 21 to drive the valve ball 21 to rotate circumferentially. The handwheel 23 is provided at the upper end of the valve stem 22 to drive the valve stem 22 to rotate circumferentially.

[0026] The angle valve body 1 has a boss 19 at its upper end. A mounting hole 20 with an inverted T-shaped cross section extends through the center of boss 19. The lower end of a valve stem 22 pivotally engages within mounting hole 20. An arcuate retaining groove 8 is defined on the inner wall of the lower end of mounting hole 20, with a central angle of 90 degrees. A retaining bump 9 is provided on the outer wall of the lower end of valve stem 22, slidingly positioned within arcuate retaining groove 8.

[0027] The upper end of the angle valve body 1 is provided with a lower retaining ring 101, which surrounds the boss 19. The height of the lower retaining ring 101 is greater than the height of the boss 19. The lower end of the hand wheel 23 is provided with an upper retaining ring 2301, which surrounds the lower retaining ring 101.

[0028] A limit slot 10 is defined at the upper end of the valve ball 21 , and a limit plug 11 is disposed at the lower end of the valve stem 22 . The limit plug 11 is inserted and fixed in the limit slot 10 .

[0029] The lower end of the handwheel 23 is provided with a plug-in groove 12, into which the upper end of the valve stem 22 is inserted. The upper end of the handwheel 23 is provided with a countersunk hole 13, in which a locking bolt 14 is disposed.
