[0002] The ball valve is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the media on the pipeline, but also close any channel to connect the other two channels.

[0003] The existing ball valves have the problem of inaccuracy in flow regulation and cannot meet the precise flow requirements of some specific usage scenarios. After adjusting the flow, the traditional ball valve is prone to change position due to water flow impact or external vibration due to the lack of an effective fixed structure, resulting in unstable flow. Therefore, a flow regulating ball valve is proposed. Utility Model Content

The shaft 8 and the valve core 11 are both provided with a first slide groove 9. The second handle 7 is rotated 90 degrees clockwise, so that the valve core 11 rotates accordingly, so that the valve core 11 is blocked inside the ball valve body 1. At this time, the two ends of the water inlet pipe 2 and the water outlet pipe 4 are not connected. At this time, the first handle 66 and the second handle 7 are parallel, and the baffle 610 blocks the inside of the through groove 10 so that the outside of the sealing ring 69 is seamlessly attached to the inside of the through groove 10. The second handle 7 is fixed to the outside of the top of the second rotating shaft 8, and the valve core 11 seamlessly rotatably connected to the inner wall of the ball valve body 1 is fixed at one end of the bottom of the second rotating shaft 8. An adjustment component 6 is provided on one side of the valve core 11;

[0028] In order to facilitate the adjustment of the flow rate, an adjustment component 6 is provided, which includes a limit plate 61 and a first rotating shaft 68. A first handle 66 is fixed on the top of the first rotating shaft 68. A plurality of limit grooves 62 are provided on one side of the limit plate 61. When the pull block 67 is pulled upward, the limit rod 63 leaves the inner side of the limit groove 62. At the same time, the limit block 64 compresses the spring 65. Then the first handle 66 can be rotated clockwise. A baffle plate 610 is fixed to the bottom of the first rotating shaft 68. The outer side of the first rotating shaft 68 is seamlessly rotatably connected to the inner side of the first slide groove 9. A sealing ring 69 is bonded to the outer side of the baffle plate 610. The outer side of the sealing ring 69 is attached to the inner side wall of the through groove 10. One side of the limit plate 61 is fixed to the outer side of the connecting frame 5. One side of the first handle 66 movably passes through the limit rod 63. The bottom of the limit rod 63 The outer side of the limit rod 63 is adapted to the inner side of the limit groove 62, and a pull block 67 is fixed on the top of the limit rod 63. The angle of the limit groove 62 is fixed. After the first handle 66 is rotated, the pulling force of the pull block 67 is released. At this time, under the elastic force of the spring 65, the limit block 64 and the limit rod 63 are pushed downward, and the limit rod 63 is inserted into the inner side of the limit groove 62 on the lower side of the rotated first handle 66. The outer side of the limit rod 63 is fixed with a limit block 64 located on the top of the limit plate 61, and the outer side of the limit rod 63 is sleeved with a spring 65, and the two ends of the spring 65 are respectively connected to one side of the first handle 66 and the limit block 64. When the limit rod 63 is inserted into the inner side of the limit groove 62, the flow rate will not change due to the larger and larger channel between the baffle 610 and the through groove 10 when the water flow hits one side of the baffle 610.

[0029] Working principle: When the ball valve body 1 is needed, the water inlet pipe 2 and the water outlet pipe 4 only need to be connected to the ball valve body 1 through the hexagonal nut 3 and the raw material tape seal. Figure 1 The position shown by the middle locking second handle 7 is the valve core 11 open state, so that the water inlet pipe 2 and the water outlet pipe 4 are in a connected state, and the second handle 7 is rotated 90 degrees clockwise, so that the valve core 11 follows the rotation, so that the valve core 11 is blocked inside the ball valve body 1, and the two ends of the water inlet pipe 2 and the water outlet pipe 4 are in a disconnected state. At this time, the first handle 66 and the second handle 7 are parallel, and the baffle 610 blocks the inner side of the through groove 10 so that the outer side of the sealing ring 69 is seamlessly attached to the inner side of the through groove 10;

[0030] When the water inlet pipe 2 and the water outlet pipe 4 are in a connected state, in order to adjust the flow of the valve core 11 of the ball valve body 1, it is only necessary to pull the pull block 67 upwards. At this time, the limit rod 63 leaves the inner side of the limit groove 62, and the limit block 64 compresses the spring 65. Then the first handle 66 can be rotated clockwise. The angle of each limit groove 62 is fixed. After rotating the first handle 66, the pulling force of the pull block 67 is released. At this time, under the elastic force of the spring 65, the limit block 64 and the limit rod 63 are pushed downward, so that the limit rod 63 is inserted into the inner side of the limit groove 62 on the lower side of the rotated first handle 66. At this time, the flow adjustment of the ball valve body 1 is completed. At the same time, when the limit rod 63 is inserted into the inner side of the limit groove 62, the flow will not change due to the larger and larger channel between the baffle 610 and the through groove 10 when the water flow hits one side of the baffle 610.

[0031] The rotation angle of the first handle 66 corresponds to the angle of the limit groove 62. The user can adjust the flow of the valve core 11 by precisely controlling the rotation angle of the first handle 66, avoiding the problem of inaccurate flow regulation in the traditional ball valve body 1 and meeting the precise flow requirements of different usage scenarios. After adjusting the flow, the limit rod 63 is inserted into the new limit groove 62 through the elastic force of the spring 65, thereby fixing the position of the first handle 66 and ensuring stability after adjustment. Even under the impact of water flow or external vibration, the position of the baffle 610 will not change easily.
