[0002] In existing technologies, traditional ball valves often employ a one-piece structure design, which presents numerous inconveniences during manufacturing and installation. On one hand, the large size of one-piece ball valves during transportation makes them susceptible to damage, increasing transportation costs and risks. On the other hand, during installation, the complex valve structure often requires significant time and effort for positioning and adjustment, impacting installation efficiency and potentially leading to decreased sealing performance and affecting overall usability due to improper installation. To address these issues, split-type ball valve designs have gradually emerged in the market. However, early split-type ball valves still have several shortcomings in positioning and installation. For example, the connection methods of some split-type ball valves are not robust enough, easily leading to loosening or leakage during use; furthermore, the positioning accuracy of some split-type ball valves is not high, requiring repeated adjustments during installation, increasing installation difficulty and time costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution:

[0020] As attached Figure 1-3 As shown, this utility model discloses a split-type ball valve that facilitates positioning and installation, including a main valve body 1 and a side valve body 2 disposed on at least one side of the main valve body 1. A valve cavity 3 is formed within the main valve body 1, and a water flow channel 4 communicating with the valve cavity 3 is formed within the side valve body 2. A positioning annular groove 5 is formed on the end of the side valve body 2 closest to the main valve body 1. At least two positioning ends 6 of different shapes are provided within the positioning annular groove 5. A positioning protrusion 7 is provided on the main valve body 1 corresponding to the positioning annular groove 5. A positioning hole 8 corresponding to the positioning end 6 is formed on the positioning protrusion 7. The positioning protrusion 7 extends into the positioning annular groove 5 and connects to the side valve body 2. The positioning end 6 extends into the corresponding positioning hole 8 to position the side valve body 2 on the main valve body 1. Specifically, in this design, by setting the ball valve body as a split structure composed of a main valve body 1 and a side valve body 2, not only is the installation process simplified, but the accuracy and flexibility of installation are also significantly improved. The positioning ring groove 5 on the side valve body 2 can mate with the positioning protrusion 7 on the main valve body 1 to achieve precise docking and ensure a seamless connection between the water flow channel 4 and the valve cavity 3. This design not only improves the sealing performance of the valve but also greatly enhances the overall structural stability. Furthermore, positioning ends 6 of various shapes are set in the positioning ring groove 5, and the positioning protrusion 7 on the main valve body 1 is equipped with positioning holes 8 of corresponding shapes. This ensures that during the connection process, each positioning end 6 can be accurately embedded into the corresponding positioning hole 8, forming a stable locking mechanism. At the same time, it ensures that after each positioning end 6 mates with the positioning hole 8, the side valve body 2 and the main valve body 1 are in the accurate installation position without the need for fine-tuning, thus facilitating the subsequent fixing of the two with bolts.

[0021] Furthermore, the positioning end 6 includes an upper positioning end 9 and a lower positioning end 10. The upper positioning end 9 has a triangular cross-section, and the lower positioning end 10 has a semi-circular cross-section. The positioning holes 8 are provided with an upper positioning hole 11 and a lower positioning hole 12 corresponding to the upper positioning end 9 and the lower positioning end 10, respectively. The shapes of the upper positioning hole 11 and the lower positioning hole 12 correspond to the upper positioning end 9 and the lower positioning end 10. Specifically, in this embodiment, the triangular upper positioning end 9, due to its stable geometric characteristics, can effectively resist lateral stress and prevent the side valve body 2 from shifting or loosening during installation or use. The semi-circular design of the lower positioning end 10 utilizes the smooth transition characteristics of a circle, reducing friction with the positioning hole 8, making the connection process smoother, and also buffering to a certain extent the minor deformation that may be caused by water flow fluctuations or temperature changes, ensuring the long-term stable operation of the valve.

[0022] Furthermore, the positioning ring groove 5 and the water flow channel 4 are arranged in a concentric circle structure. A sealing ring groove 13 is also provided between the positioning ring groove 5 and the water flow channel 4. A sealing ring 14 is provided inside the sealing ring groove 13. The sealing ring 14 is made of plastic, and its two sides are respectively sealed to the inside of the sealing ring groove 13 of the main valve body 1 and the side valve body 2. Specifically, in this embodiment, by adopting a concentric circle structure design, the positioning ring groove 5 and the water flow channel 4 not only maintain structural harmony and unity, but also further enhance the connection strength between the side valve body 2 and the main valve body 1. This design not only facilitates the smooth flow of water in the channel, but also ensures that the positioning ring groove 5, as a key connection part, can evenly bear the force from all directions, preventing damage caused by stress concentration.

[0023] Furthermore, a main sealing groove 15 is provided on the main valve body 1 at the position corresponding to the sealing ring groove 13. The side of the sealing ring 14 away from the side valve body 2 extends into the main sealing groove 15 and connects to the main valve body 1. Several sealing ring fixing ends 16 protrude from the groove wall of the sealing ring groove 13 and are evenly spaced on the groove wall of the sealing ring groove 13. A positioning port 17 corresponding to the sealing ring fixing end 16 is opened on the side of the sealing ring 14 near the side valve body 2, and the sealing ring fixing end 16 extends into the corresponding positioning port 17 and connects to the sealing ring 14. Specifically, in this embodiment, the sealing ring 14 is sealed to the main sealing groove 15 on the main valve body 1 and the sealing ring groove 13 on the side valve body 2, which can enhance the overall sealing performance of the ball valve, effectively prevent media leakage, and ensure stable system operation. The positioning port 17 on the sealing ring 14 cooperates with the sealing ring fixing end 16 on the groove wall of the sealing ring groove 13, which can prevent the sealing ring 14 from rotating in the sealing ring groove 13, further enhancing the stability and reliability of the sealing ring 14.

[0024] Furthermore, a main positioning part 18 protrudes from the main valve body 1, and a side positioning part 19 is provided on the side valve body 2 corresponding to the main positioning part 18. A main connecting hole 20 and a side connecting hole 21 are respectively formed on the main positioning part 18 and the side positioning part 19, and a connecting bolt 22 is provided between the main connecting hole 20 and the side connecting hole 21. Specifically, in this embodiment, at least two main positioning parts 18 are provided, and the main positioning parts 18 are symmetrically arranged on both sides of the top end of the main valve body 1.
