For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] See also Figure 1-4 As shown, this embodiment provides a spliced ​​combined valve ball, including a first hemisphere 110 and a second hemisphere 120, the first hemisphere 110 and the second hemisphere 120 are connected to form a sphere 100, and a channel 130 is arranged inside the sphere 100; a sleeve 200 is arranged in the channel 130; two annular grooves 140 are provided, and the annular grooves 140 are arranged on the sphere 100 along the circumference of both ends of the channel 130; a fixing ring 300 is inserted in the annular groove 140, and one end of the fixing ring 300 is also fixed to the sleeve 200.

[0038] It can be understood that by providing the first hemisphere 110 and the second hemisphere 120, the sphere 100 can be easily split into two parts, thereby facilitating disassembly, cleaning and maintenance. By providing the bushing 200, the first hemisphere 110 and the second hemisphere 120 can be easily connected, and the bushing 200 can also be brought into contact with the transport medium in the channel 130, thereby preventing the channel 130 from directly contacting the transport medium and causing contamination and corrosion to the sphere 100. When the bushing 200 is contaminated and corroded, it only needs to be removed for cleaning or replacement, thereby reducing maintenance costs and being highly practical. By providing the annular groove 140 and the fixing ring 300, the bushing 200 can be more firmly connected to the sphere 100.

[0039] In a specific embodiment of the present application, the cross-section of the fixing ring 300 is L-shaped, so that one end of the fixing ring 300 is inserted into the annular groove 140 and the other end is bent toward the bushing 200 and fixed to the end of the bushing 200 .

[0040] It is understandable that the cross section of the fixing ring 300 is set to be L-shaped, which can facilitate fixing the bushing 200 on the sphere 100, so that the bushing 200 is firmly installed, and can also make the connection between the first hemisphere 110 and the second hemisphere 120 more rigorous and firm.

[0041] In a specific embodiment of the present application, the spliced ​​assembly valve ball further includes a sealing ring 141 , which is disposed on the inner side wall of the annular groove 140 , and is used to reinforce the connection between the fixing ring 300 and the annular groove 140 .

[0042] It is understandable that the sealing ring 141 is provided on the inner wall of the annular groove 140 , so that the connection between the fixing ring 300 and the sphere 100 can be tighter, thereby strengthening the connection between the bushing 200 and the sphere 100 , and also strengthening the connection between the first hemisphere 110 and the second hemisphere 120 .

[0043] In a specific embodiment of the present application, the spliced ​​combination valve ball also includes a groove 400, which is arranged on the ball 100 and is perpendicular to the annular groove 140; a positioning pin 410, which is arranged in the groove 400, and the positioning pin 410 passes through the fixing ring 300 and is inserted into the ball 100, and the positioning pin 410 is used to fix the fixing ring 300.

[0044] It is understandable that the groove 400 is provided to facilitate the installation of the fixing pin, so that the fixing pin passes through the fixing ring 300 and is inserted into the sphere 100, which can strengthen the connection between the fixing ring 300 and the sphere 100, thereby further strengthening the connection between the bushing 200 and the sphere 100, making the connection between the first hemisphere 110 and the second hemisphere 120 more tight.

[0045] In a specific embodiment of the present application, a convex strip 121 and a concave strip 122 are provided at the connection between the first hemisphere 110 and the second hemisphere 120. The convex strip 121 of the first hemisphere 110 and the concave strip 122 of the second hemisphere 120 are provided correspondingly and fit together, and the concave strip 122 of the first hemisphere 110 and the convex strip 121 of the second hemisphere 120 are provided correspondingly and fit together, so that the first hemisphere 110 and the second hemisphere 120 are tightly connected.

[0046] It is understandable that the provision of the convex strips 121 and the concave strips 122 can increase the friction between the first hemisphere 110 and the second hemisphere 120, so that the first hemisphere 110 and the second hemisphere 120 fit precisely, the connection is not prone to deflection, and the first hemisphere 110 and the second hemisphere 120 are connected accurately and tightly.

[0047] In a specific embodiment of the present application, the spliced ​​assembly valve ball further includes a connection groove 150 , which is disposed on the top of the ball 100 , and the connection groove 150 is used to connect the valve stem.

[0048] In a specific embodiment of the present application, the spliced ​​combined valve ball further includes a sealing cover 151 , which is disposed on the inner bottom surface of the connecting groove 150 , so that the first hemisphere 110 and the second hemisphere 120 are tightly connected.

[0049] It can be understood that the sealing cover 151 is arranged on the inner bottom surface of the connecting groove 150, which can not only strengthen the connection between the first hemisphere 110 and the second hemisphere 120, but also prevent dirt from falling from the connecting groove 150 into the gap between the first hemisphere 110 and the second hemisphere 120, thereby avoiding affecting the normal operation of the valve.

[0050] In a specific embodiment of the present application, the spliced ​​combined valve ball further includes a buffer layer 500 which is arranged in an annular shape. The buffer layer 500 is sleeved on the outer wall of the bushing 200 and is located between the bushing 200 and the ball 100 .

The buffer layer 500 can be made of elastic materials such as rubber and plastic, has good buffering effect and corrosion resistance, and can adapt to various environments and usage scenarios.

[0052] In a specific embodiment of the present application, the inner diameter of the buffer layer 500 is less than or equal to the outer diameter of the bushing 200 .

[0053] It is understandable that the inner diameter of the buffer layer 500 is less than or equal to the outer diameter of the bushing 200, so that the connection between the buffer layer 500 and the bushing 200 is tighter and less likely to loosen, thereby ensuring the buffering effect.

[0054] In a specific embodiment of the present application, the outer diameter of the buffer layer 500 is greater than or equal to the diameter of the channel 130 .

[0055] It is understandable that the outer diameter of the buffer layer 500 is greater than or equal to the diameter of the channel 130, so that the buffer layer 500 is in closer contact with the inside of the channel 130 and is not prone to loosening, thereby ensuring the buffering effect.

[0056] The working principle of the utility model is as follows: a buffer layer 500 is sleeved on the outer wall of the bushing 200, the first hemisphere 110 and the second hemisphere 120 are installed on the outside of the buffer layer 500, the fixing ring 300 is inserted into the annular groove 140 and fixed to the bushing 200, and the positioning pin 410 is fixed to complete the splicing combination of the sphere 100. When the bushing 200 needs to be cleaned or replaced, the positioning pin 410, the fixing ring 300, etc. are removed in sequence to complete the disassembly, and then the bushing 200 can be cleaned or replaced.

[0057] In summary, the first hemisphere 110 and the second hemisphere 120 are provided, so that the sphere 100 can be conveniently split into two parts, thereby facilitating disassembly, cleaning and maintenance. The bushing 200 is provided, so that the first hemisphere 110 and the second hemisphere 120 can be conveniently connected, and the bushing 200 can also be made to contact with the transport medium in the channel 130, thereby preventing the channel 130 from directly contacting with the transport medium and causing pollution and corrosion to the sphere 100. When the bushing 200 is contaminated and corroded, it only needs to be removed for cleaning or replacement, thereby reducing maintenance costs and being highly practical. The annular groove 140 and the fixing ring 300 can make the connection between the bushing 200 and the sphere 100 more firmly.

[0058] Furthermore, the cross section of the fixing ring 300 is set to be L-shaped, which can facilitate the fixing of the bushing 200 on the sphere 100, so that the bushing 200 is firmly installed, and the connection between the first hemisphere 110 and the second hemisphere 120 is more tight and firm. The sealing ring 141 is arranged on the inner side wall of the annular groove 140, which can make the connection between the fixing ring 300 and the sphere 100 more tight, thereby reinforcing the connection between the bushing 200 and the sphere 100, and also reinforcing the connection between the first hemisphere 110 and the second hemisphere 120. The groove 400 is arranged to facilitate the installation of the fixing pin, so that the fixing pin passes through the fixing ring 300 and is inserted into the sphere 100, which can reinforce the connection between the fixing ring 300 and the sphere 100, thereby reinforcing the connection between the bushing 200 and the sphere 100 again, and making the connection between the first hemisphere 110 and the second hemisphere 120 more tight.

[0059] Furthermore, the convex strips 121 and the concave strips 122 are provided to increase the friction between the first hemisphere 110 and the second hemisphere 120, so that the first hemisphere 110 and the second hemisphere 120 fit precisely and the connection is not easily deflected, so that the first hemisphere 110 and the second hemisphere 120 are connected precisely and tightly. The sealing cover 151 is provided on the inner bottom surface of the connecting groove 150, which can not only strengthen the connection between the first hemisphere 110 and the second hemisphere 120, but also prevent dirt from falling from the connecting groove 150 into the gap between the first hemisphere 110 and the second hemisphere 120, so as to avoid affecting the normal operation of the valve.

[0060] Furthermore, the setting of the buffer layer 500 can effectively reduce the impact force of the transport medium on the bushing 200 and the ball 100, and improve the service life of the bushing 200 and the ball 100. At the same time, it can also play a role in heat insulation and heat preservation, thereby improving the performance of the valve. The inner diameter of the buffer layer 500 is less than or equal to the outer diameter of the bushing 200, and the outer diameter of the buffer layer 500 is greater than or equal to the diameter of the channel 130, so that the connection between the buffer layer 500 and the bushing 200 is more tightly and not easy to loosen, thereby ensuring the buffer effect.
