DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] As attached Figure 1 and 2 As shown;

[0029] The present embodiment discloses a high-stability quick-matching ball valve ball, including a ball body 11, a main mounting groove 12 is opened at the upper end of the ball body 11, and the main mounting groove 12 is used for the valve stem 13 to extend into for assembly; side mounting grooves 21 are opened on both sides opposite to the main mounting groove 12 in the ball body 11, and the inner sides of the two side mounting grooves 21 are notches and communicate with the main mounting groove 12. Side pressure fixing components are provided in the two side mounting grooves 21, and the side pressure fixing components include an internal pressure spring 22 and a side pressure fixing block 23. The side pressure fixing block 23 will partially extend out of the notch of the side mounting groove 21 under the internal pressure of the internal pressure spring 22 and have an internal pressure tendency; the upper end of the inner side of the side pressure fixing block 23 has an avoidance inclined surface 231, and the avoidance inclined surface 231 can be gradually pushed outward by the valve stem 13 during the process of the valve stem 13 extending into the main mounting groove 12, so that the side pressure fixing block 23 is completely retracted into the side mounting groove 21;

[0030] Both sides of the valve stem 13 are provided with side pressure fixing grooves 24 adapted to the side pressure fixing blocks 23; when the valve stem 13 extends into the bottom of the main installation groove 12, the two side pressure fixing blocks 23 can be pressed into the corresponding side pressure fixing grooves 24 at the same time to achieve rapid matching between the spherical body 11 and the valve stem 13.

[0031] Among them, the side compression assembly also includes a balancing block 31 fixed on the outside of the side compression block 23, and the balancing block 31 and the side compression block 23 are fixed by screws; the width of the balancing block 31 is adapted to the side mounting groove 21 so that the side compression block 23 can move horizontally smoothly; the internal pressure spring 22 is squeezed between the balancing block 31 and the bottom of the side mounting groove 21; a filling block 41 is fixed at the groove of the side mounting groove 21 by screws, and the filling block 41 is in contact with the lower end surface of the side mounting groove 21 and forms a space between the filling block 41 and the upper end surface of the side mounting groove 21 for the side compression block 23 to move horizontally; the filling block 41 will collide with the balancing block 31 to limit the side compression block 23.

[0032] An inner sleeve seat 42 is fixedly mounted at the bottom of the side mounting groove 21, and an internal pressure spring 22 is sheathed around the outer periphery of the inner sleeve seat 42. A force-applying pull block 51 is fixedly mounted on the outer side of the balancing weight 31, extending outward. A first inner hole 61 and a second inner hole 62 are respectively defined within the inner sleeve seat 42 and within the spherical body 11, allowing the force-applying pull block 51 to extend outside the spherical body 11. An arc-shaped cover plate 71 is fixedly mounted on the outer side of the force-applying pull block 51 via screws. When the side pressure-fixing block 23 is pressed into the corresponding side pressure-fixing groove 24, the outer surface of the arc-shaped cover plate 71 and the surface of the spherical body 11 become smooth.

[0033] The outer side of the arc-shaped cover plate 71 is provided with a recessed area 72 for fingers to insert into and apply force.

[0034] Two symmetrical side grooves 81 are formed between the arc-shaped cover plate 71 and the force-applying pull block 51. A locking block 82 and a locking spring 83 are provided in each of the side grooves 81. Under the elastic force of the locking spring 83, the locking block 82 has a tendency to move away from the center of the arc-shaped cover plate 71 and leave the side groove 81.

[0035] When the force-applying pull block 51 is pulled out of the second inner hole 62 , the two blocking blocks 82 can partially leave the side groove 81 and collide with the surface of the spherical body 11 to limit the position of the force-applying pull block 51 ;

[0036] When the two locking blocks 82 partially leave the side groove 81 and collide with the surface of the spherical body 11 , the side pressing block 23 is in a state of retreating into the side installation groove 21 .

[0037] Among them, an anti-drop rope 84 is fixedly provided between the bottom of the side groove 81 and the blocking block 82.

[0038] The working principle of this embodiment is:

[0039] 1. When assembling the spherical body 11, align the valve stem 13 with the main mounting groove 12 at the upper end of the spherical body 11 and extend it downward; during this process, the avoidance inclined surface 231 on the side pressure fixing block 23 will be gradually pushed outward by the valve stem 13 so that the side pressure fixing block 23 is completely retracted into the side mounting groove 21, thereby realizing the automatic inward movement of the side pressure fixing block 23, allowing the valve stem 13 to smoothly extend downward to the bottom of the main mounting groove 12.

[0040] 2. When the valve stem 13 extends to the bottom of the main installation groove 12 , the two side pressing blocks 23 will correspond to the positions of the two side pressing grooves 24 .

[0041] 3. After pressing the two locking blocks 82 with your hands, the two locking blocks 82 move inward to the inside of the side groove 81; then, based on the internal pressure of the internal pressure spring 22, the side pressure fixing block 23 moves inward and is pressed into the corresponding side pressure fixing groove 24, realizing quick matching between the spherical body 11 and the valve stem 13.

[0042] 4. When disassembling the ball body 11, insert your fingers into the recessed area 72 and apply force to pull the arc-shaped cover plate 71 outwards. The side pressure fixing block 23 will then move outwards and leave the corresponding side pressure fixing groove 24. Then, the two locking blocks 82 will partially leave the side groove 81 under the elastic force of the corresponding locking spring 83 and collide with the surface of the ball body 11 to limit the position of the force-applying pulling block 51. After that, the two side pressure fixing blocks 23 can remain in the state of leaving the corresponding side pressure fixing groove 24, releasing the assembly of the ball body 11 and the valve stem 13, and facilitating the subsequent disassembly of the ball body 11. This specific embodiment is merely an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment as needed without creative contribution, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
