Description

Technical Field

[0001] This utility model relates to the field of ball valve body technology, and in particular to an assembled ball valve body. Background Technology

[0002] The ball body is a key component of a ball valve, typically spherical with a central circular orifice. It primarily controls the flow of fluid, opening or closing the valve by rotating 90 degrees. The smooth surface of the ball reduces fluid resistance and improves sealing performance. Common ball materials include stainless steel, brass, and plastic, with the choice depending on the valve's application and the working medium. Its unique structural design gives ball valves advantages such as ease of operation, rapid switching, and reliable sealing, making them widely used in petroleum, chemical, natural gas, and water treatment industries for controlling and regulating the flow rate of media in pipelines.

[0003] However, the ball in ball valves is currently mainly obtained by cutting and milling, which results in poor production efficiency. The ball valve ball cannot be obtained as a complete whole through casting and assembly.

[0004] Therefore, an assembled ball valve ball is proposed to solve or alleviate the above problems. Utility Model Content

[0025] A type of assembled ball valve ball, such as Figures 1 to 3 As shown, it includes an inner ring channel 6, and a superior arc portion 1 and a inferior arc portion 3 that are sleeved on the outer ring of the inner ring channel 6 and detachably connected to each other. There is a gap between the inner ring channel 6 and the superior arc portion 1 and the inferior arc portion 3, and the gap is filled with sealant.

[0026] The outer ring of the inferior arc portion 3 has recesses 4 at both ends. The inferior arc portion 3 located on both sides of the recesses 4 forms limiting portions 5. The two ends of the superior arc portion 1 are fixedly connected to protrusions 2 that can be embedded in the recesses 4. The protrusions 2 are restricted between the limiting portions 5 on both sides. The outer ring of the inner ring channel 6 has a cylindrical groove 7. The inner ring of the superior arc portion 1 is fixedly connected to a superior arc insert 14 that can be embedded in the cylindrical groove 7. The inner ring of the inferior arc portion 3 is fixedly connected to an inferior arc insert 15 that can be embedded in the cylindrical groove 7.

[0027] The inner ring of the inferior arc insert 15 is provided with a groove 8, and the bottom of the groove 8 is provided with a through hole 9 that penetrates the inferior arc insert 3. An insert block 10 is detachably connected in the groove 8. The bottom surface of the insert block 10 is flush with the inner ring of the inferior arc insert 15. A valve stem 11 that penetrates the through hole 9 is fixedly connected to the top surface of the insert block 10. A connecting part 12 is fixedly connected to the end of the valve stem 11 away from the insert block 10. A through hole 9 is provided on the connecting part 12.

[0028] When this utility model is actually assembled, the inner ring channel 6 is simply inserted into the superior arc portion 1 through the opening between the protrusions 2 at the top of the superior arc portion 1. At this time, the superior arc insert 14 of the inner ring of the superior arc portion 1 can be inserted into the cylindrical groove 7 on the outside of the inner ring channel 6. Then, the operator inserts the valve stem 11 through the groove 8 and the through hole 9, so that the insert 10 is inserted into the groove 8. Then, the inferior arc portion 3 is aligned with the two protrusions 2 at both ends of the superior arc portion 1 along the length of the central axis of the inner ring channel 6, and slides into it. At first, the limiting portion 5 will abut against the protrusion 2. With further pressure, the protrusion 2 undergoes a certain degree of elastic deformation, so that the protrusion 2 can be inserted into the recess 4 between the two limiting portions 5. Thus, the inferior arc insert 15 can also be inserted into the cylindrical groove 7 on the outside of the inner ring channel 6. Finally, the operator only needs to fill the gap with sealant to obtain a complete sphere.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
