Description

Technical Field

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

[0002] Currently, most ball valves consist of a ball valve core, a valve seat, and a valve stem. A cylindrical through hole is opened in the middle of the ball valve core, which divides the valve into a first chamber that communicates with the inlet and a second chamber that communicates with the outlet. Rotating the valve stem can drive the ball to rotate, selectively connecting or disconnecting the first and second chambers, and can be used for fluid regulation and control.

[0003] In the existing technology, most ball valve cores used in ball valves have simple structures and can only play the role of regulating and controlling fluids. However, they cannot play a filtering role when regulating and controlling fluids containing a small amount of impurities, and the impurities can only be discharged together with the fluid.

[0014] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0016] Example 1: This embodiment provides a valve ball assembly, including: The upper spherical shell 1 includes a mounting hole 11 and a liquid outlet hole 12. The mounting hole 11 is located on the top of the upper spherical shell 1, and the liquid outlet hole 12 is located on the periphery of the upper spherical shell 1. The lower spherical shell 2 includes a fixing post 21 and a liquid inlet 22. The fixing post 21 is disposed in the lower spherical shell 2 along the Z direction and a fixing hole 23 is provided on the top of the fixing post 21. The liquid inlet 22 is provided on the periphery of the lower spherical shell 2. The filter element 3 includes a base frame 31 and a filter screen 32. The base frame 31 is mounted on the fixed column 21 and is disposed between the upper spherical shell 1 and the lower spherical shell 2. The filter screen 32 is disposed on the base frame 31. The valve stem 4 is provided with a first connecting section 41 and a second connecting section 42. The first connecting section 41 is adapted to be connected to the fixing hole 23, and the second connecting section 42 is adapted to be connected to the mounting hole 11.

[0017] In this technical solution, the filter element 3 is first installed on the lower ball shell 2, and then the upper ball shell 1 and the lower ball shell 2 are installed together along the Z direction, so that the filter element 3 is located between the lower ball shell 2 and the upper ball shell 1, so that the filter element 3 divides the interior of the spherical valve body composed of the lower ball shell 2 and the upper ball shell 1 into an inlet chamber and an outlet chamber.

[0018] Then, the spherical valve body is installed into the valve body for use. The inlet pipe of the valve body is connected to the inlet hole 22, and the outlet pipe of the valve body is connected to the outlet hole 12. The valve stem 4 is installed on the valve body along the Z direction. The first connecting section 41 of the valve stem 4 is inserted into the fixing hole 23 on the fixing column 21 in the lower ball shell 2. The second connecting section 42 of the valve stem 4 is inserted into the mounting hole 11 of the upper ball shell 1. This structural design allows the valve stem 4 to drive the upper ball shell 1 and the lower ball shell 2 to rotate together in a circumferential direction when rotating, thereby realizing the control and regulation of the fluid.

[0019] When the fluid enters the lower spherical shell 2 through the inlet hole 22, it flows upward to the upper spherical shell 1 along the Z direction. It passes through the filter screen 32 on the filter element 3 to filter the impurities in the fluid. The filtered fluid then exits through the outlet hole 12 of the upper spherical shell 1, thereby achieving the filtration and purification of the fluid.

[0020] In summary, by designing the valve ball assembly as a detachable upper ball shell 1 and lower ball shell 2, and installing and fixing the filter element 3 between the upper ball shell 1 and the lower ball shell 2, the fluid flowing from the lower ball shell 2 to the upper ball shell 1 is filtered. This allows the valve ball assembly to have a filtering function when installed in the valve body, enabling it to filter and purify impurities in the fluid, thus demonstrating high practicality.

[0021] Example 2: This embodiment provides a valve ball assembly, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0022] Furthermore, a positioning part 24 is provided on the top of the fixed column 21, and a positioning hole is provided on the base frame 31. The positioning part 24 and the positioning hole are inserted and fitted together along the Z direction. When the first connecting section 41 of the valve stem 4 is connected to the fixing hole 23, the valve stem 4 abuts against the base frame 31 along the Z direction.

[0023] In this technical solution, the positioning part 24 can be prismatic in shape, while the positioning hole is adapted to the structure of the positioning part 24. The insertion and engagement between the positioning part 24 on the fixed post 21 and the positioning hole on the base frame 31 ensures that the base frame 31 can be mounted on the fixed post 21 without circumferential rotation. Furthermore, when the first connecting section 41 of the valve stem 4 is connected to the fixed hole 23, the valve stem 4 abuts against the base frame 31 along the Z-direction, pressing the base frame 31 firmly against the fixed post 21, thus enhancing stability.

[0024] Example 3: This embodiment provides a valve ball assembly, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] Furthermore, the base frame 31 also includes: A plurality of first connecting blocks 33 are arranged in a ring array on the base frame 31; A plurality of connecting holes 34 are provided on the base frame 31 along the Z direction, and are provided one-to-one between adjacent first connecting blocks 33; The lower spherical shell 2 has an annular groove 25, the upper spherical shell 1 has a number of second connecting blocks 13, a number of first connecting blocks 33 are inserted into the annular groove 25, and the number of second connecting blocks 13 respectively pass through a number of connecting holes 34 and are inserted into the annular groove 25.

[0026] In this technical solution, the base frame 31 is installed on the lower spherical shell 2 through the insertion and engagement of the first connecting block 33 and the annular groove 25, further enhancing the installation stability of the base frame 31 on the lower spherical shell 2. Then, the upper spherical shell 1 is inserted and engaged with the annular groove 25 through the connecting hole 34 via the second connecting block 13, realizing the splicing between the upper spherical shell 1 and the lower spherical shell 2, and also pressing the base frame 31 tightly onto the lower spherical shell 2. Furthermore, a magnetic block 26 is provided at the bottom of the annular groove 25, and both the first connecting block 33 and the second connecting block 13 are made of metal; wherein, both the first connecting block 33 and the second connecting block 13 are attracted to the magnetic block 26. By using the magnetic block 26 to attract the first connecting block 33 and the second connecting block 13, the connection stability between the base frame 31 and the lower spherical shell 2, as well as between the upper spherical shell 1 and the lower spherical shell 2, is enhanced, thereby making the structure between the upper spherical shell 1, the filter element 3, and the lower spherical shell 2 more stable and highly practical.

[0027] In addition, annular extension sections are provided on the periphery of both the upper ball shell 1 and the lower ball shell 2. The two annular extension sections are connected together by fasteners, and a rubber sealing gasket is provided between them to ensure the connection is sealed. This structural design enhances the connection between the upper ball shell 1 and the lower ball shell 2 and also facilitates the assembly and use of the valve ball assembly in the valve body.

[0028] Example 4: This embodiment provides a valve ball assembly, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] Furthermore, a support frame 27 is provided at the bottom of the lower spherical shell 2.

[0030] Furthermore, the lower spherical shell 2 also includes: Drainage hole 28 is provided at the bottom of the lower spherical shell 2; Drain plug 29 is detachably installed at the bottom of the lower spherical shell 2 to block the drain hole 28.

[0031] Furthermore, the drain plug 29 is threaded onto the bottom of the lower spherical shell 2.

[0032] In this technical solution, the support frame 27 can enhance the stability of the valve ball assembly when it is installed and used in the valve body, and the bottom of the drain plug 29 is higher than the bottom of the support frame 27, so that the drain plug 29 is located inside the support frame 27. After the ball valve has been used for a long time, the valve ball assembly can be removed from the valve body. By removing the drain plug 29 from the lower ball shell 2, the filtered impurities can be discharged from the lower ball shell 2, preventing the accumulation of impurities from affecting the regulation and control of the fluid.

[0033] Alternatively, a drain port structure can be directly provided at the bottom of the corresponding position of the valve body, and a removable sealing block can be set at the drain port. By first removing the sealing block, the drain plug 29 can be exposed from the valve body, and then the drain plug 29 can be removed to achieve the discharge of impurities. This way, it is not necessary to remove the entire valve ball assembly from the valve body.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
