Description

Technical Field

[0001] This utility model belongs to the field of valve ball technology, and in particular relates to a combined valve ball. Background Technology

[0002] The valve ball is a component of a ball valve, which is commonly used in pipelines to control the flow of substances within them. The main function of the valve ball is to control the flow and stop of substances in the pipeline. The valve ball is typically spherical with a flow hole on its arc surface. Rotation of the valve ball controls the flow and stop of substances in the pipeline. A search revealed patent application number 202421036562.7, which discloses a combined valve ball, including a hemisphere one, a hemisphere two located on the right side of the hemisphere one, and a handle at the top of both hemispheres. A disassembly / assembly mechanism is located at the bottom of the handle, comprising a groove, a fixing block, a slot, an insert block, a connecting piece, a limit rod, a spring, and a lever. The groove is located at the top of both hemispheres, the fixing block is inserted into the groove, and the handle is fixedly mounted on top of the fixing block. The slot is located on one side of the inner wall of the groove, and the insert block is inserted into the slot.

[0003] However, in actual use, the applicant found that when replacing the rotary handle, personnel need to turn a lever, which moves the connecting plate to compress the spring. The connecting plate then moves the insert block out of the slot, allowing the fixing block to be pulled out and the rotary handle to be replaced. Although this makes it convenient for personnel to replace the rotary handle, its structure is relatively complex and therefore inconvenient to process. In view of this, we propose a combined valve ball. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A combined valve ball includes a ball 1 and a valve stem 4. A connecting post 2 is fixedly connected to the top of the ball 1. A rectangular slot 21 is formed on the top of the connecting post 2. A rectangular insert 8 is fixedly connected to the lower end of the valve stem 4. The rectangular insert 8 is inserted into the rectangular slot 21. A limiting circular plate 41 is fixedly installed on the valve stem 4 above the rectangular insert 8. A connecting cap 3 is movably sleeved on the valve stem 4 above the limiting circular plate 41. The valve stem 4 is detachably connected to the connecting post 2 through the connecting cap 3. An external thread 22 is formed on the outer wall of the upper end of the connecting post 2. The external thread 22 is threaded into the internal thread formed on the inner wall of the connecting cap 3. The upper end of the valve stem 4 is fixed. The rotary handle 5 is connected. By unscrewing the connecting cap 3 counterclockwise from the upper end of the connecting post 2, the rectangular insert 8 can be pulled out from the rectangular slot 21 to replace the rotary handle 5. The operation is convenient and the structure is simple and easy to process. During use, when the valve stem 4 breaks and the rotary handle 5 needs to be replaced, the connecting cap 3 can be manually unscrewed from the upper end of the connecting post 2 to pull out the rectangular insert 8 from the rectangular slot 21. Then, the rectangular insert 8 at the lower end of the new valve stem 4 is inserted into the rectangular slot 21, and the connecting cap 3 is screwed onto the upper end of the connecting post 2. The connecting cap 3 presses the limiting circular plate 41, thus completing the quick replacement of the rotary handle 5.

[0022] A column cylinder 7 is fixedly connected to the middle of the sphere 1 by bolts 6. A through groove 11 is formed through the middle of the sphere 1. T-shaped connecting blocks 12 are arranged in a circular array on the inner wall of the through groove 11. T-shaped connecting slots 71 are arranged in a circular array on the outer wall of the column cylinder 7. The T-shaped connecting blocks 12 slide with the T-shaped connecting slots 71. A stepped hole 13 is formed on the outer wall of the sphere 1 above the through groove 11. A threaded hole 72 is formed on the outer wall of the column cylinder 7. The lower end of the bolt 6 passes through the stepped hole 13 and is screwed into the threaded hole 72. The through groove 11, the T-shaped connecting blocks 12 and the column cylinder 7 are of the same length. A column 7 is installed inside the sphere 1. By selecting column 7s with different inner diameters and combining them with the sphere 1, it is convenient for personnel to flexibly assemble and combine them into spheres 1 with flow channels of different diameters. When assembling the sphere 1, a column 7 with the required inner diameter can be selected according to the needs. The T-shaped connecting groove 71 on the column 7 is aligned with the T-shaped connecting block 12 on the sphere 1, and the column 7 is inserted into the through groove 11. Finally, the bolt 6 is passed through the stepped hole 13 and screwed into the threaded hole 72 to fix the column 7 in the through groove 11. This allows for quick assembly and combination into spheres 1 with flow channels of different diameters.

[0023] Working principle: When the valve stem 4 breaks and the handle 5 needs to be replaced, the connecting cap 3 can be manually unscrewed from the upper end of the connecting post 2, the rectangular insert 8 can be pulled out from the rectangular slot 21, the rectangular insert 8 at the lower end of the new valve stem 4 can be inserted into the rectangular slot 21, and the connecting cap 3 can be screwed onto the upper end of the connecting post 2. The connecting cap 3 can be used to press the limiting circular plate 41, thus completing the quick replacement of the handle 5. When assembling the ball 1, a column 7 with the required inner diameter can be selected according to the requirements. The T-shaped connecting groove 71 on the column 7 can be aligned with the T-shaped connecting block 12 on the ball 1, and the column 7 can be inserted into the through groove 11. Finally, the bolt 6 can be passed through the stepped hole 13 and screwed into the threaded hole 72 to fix the column 7 in the through groove 11. This allows for quick assembly and combination of the ball 1 with different diameter flow channels.
