[0020] In this embodiment, four third ball valve body segments 6 are each provided with a through groove 7; one side surface of the eight second ball valve body segments 4 is each provided with two second spring holes 15, and a second spring 14 is fixedly installed between the sixteen second spring holes 15; one side surface of the four third ball valve body segments 6 is each provided with four first spring holes 12, and a first spring 11 is fixedly installed between the sixteen first spring holes 12.

[0021] Specifically, the ball core is formed by assembling four third ball valve body segments 6 and eight second ball valve body segments 4. Two rubber sealing rings 5 ​​limit the four third ball valve body segments 6 from closing together. The second slider 10 is connected to the second slide groove 13 to drive the eight second ball valve body segments 4 to close. The first springs 11 and the second springs 14 in the four third ball valve body segments 6 both generate outward expansion force.

[0022] In this embodiment, grooves are provided on the top and bottom of the outer surfaces of the four third ball valve body segmentation blocks 6, and two rubber sealing rings 5 ​​are embedded and installed in the eight grooves; a driving valve column connecting groove 2 is provided on the opposite side surfaces of the two driving valve column connecting blocks 1.

[0023] Specifically, the driving valve column connecting groove 2 on the upper and lower driving valve column connecting blocks 1 is used to connect the driving valve stem, and the two rubber sealing rings 5 ​​are precisely fitted with the inner cavity of the valve body to achieve sealing. The two rubber sealing rings 5 ​​cooperate with the four third ball valve body dividing blocks 6, so that the four third ball valve body dividing blocks 6 are tightly fitted with the inner cavity of the valve body, and no wear gap will be generated after long-term use, resulting in leakage.

Two rubber sealing rings 5 ​​limit the four third ball valve body segments 6 to close together. The eight second ball valve body segments 4 are driven to close by connecting the second sliding block 10 with the second sliding groove 13. The first spring 11 and the second spring 14 in the four third ball valve body segments 6 both generate an outward expansion force. When installed inside the valve body, they fit tightly with the inner cavity of the valve body, thereby always keeping the four third ball valve body segments 6 in close contact with the inner cavity of the valve body. After long-term use, no wear gap will be generated to cause leakage.
