[0030] The diverter valve is an important fluid control component, which is widely used in many industrial fields such as petroleum, chemical industry, water treatment, and medicine. Its main function is to divert part of the fluid from the main line to meet different working requirements or achieve specific process purposes. The working principle of the diverter valve is based on the change of the fluid flow channel, and the flow direction and flow rate of the fluid are adjusted by controlling the position of the valve core. In order to achieve the diversion control of a variety of different liquids or gases, it is usually necessary to use a diverter valve body with multiple channels. The existing multi-channel diverter valve is usually equipped with multiple individually controlled valve cores in a valve body. The structure of the valve core is relatively complex, which is not easy to install and will also increase the cost of fluid control.

[0031] In order to solve the above problems, the present invention proposes a diverter valve 1000 with switchable number of flow channels, comprising a valve body 1 and a valve core structure 2, wherein the valve body 1 is formed with an installation cavity, a water inlet 111 and a plurality of external channels 112; the valve core structure 2 is rotatably arranged in the installation cavity and abuts against the inner wall of the valve body 1, and an end portion of the valve core structure 2 away from the water inlet 111 extends out of the valve body 1, and the valve core structure 2 is formed with a through cavity and a plurality of internal channels, and the through cavity connects the water inlet 111 with the internal channels; the valve core structure 2 rotates relative to the valve body 1 to control the corresponding connection or disconnection of an internal channel and an external channel 112, so that a plurality of groups of fluid channels are formed in the diverter valve 1000 with switchable number of flow channels.

[0032] The technical solution of the present invention proposes a diverter valve 1000 with switchable flow channels. By rotating the valve core structure 2, the connection or disconnection between a specific inner channel and an outer channel 112 can be controlled, thereby forming multiple groups of fluid channels inside the diverter valve 1000 with switchable flow channels, and realizing multi-channel regulation of the fluid. Avoiding the need for multiple valve core combinations to achieve fluid regulation, which leads to the structure of the diverter valve 1000 with switchable flow channels being too complicated, simplifies the structure of the diverter valve 1000 with switchable flow channels, and allows the flow direction of the fluid to be adjusted by changing the position of the valve core, providing a dynamic fluid control method. The path of the fluid can be easily changed by rotating the valve core structure 2, without complex mechanical operations, simplifying the fluid control process. At the same time, switching of the fluid channel by rotation helps to reduce the resistance of the fluid flow, which can reduce energy consumption and maintenance costs. In addition, the contact between the valve core structure 2 and the inner wall of the valve body 1 helps to ensure the sealing of the fluid during the switching process, avoid leakage, and improve the safety and reliability of the system.

[0033] In an optional embodiment, in order to realize the flow diversion control of the external channel 112, the external channel 112 includes a first external channel 112a and a second external channel 112b, and the first external channel 112a and the second external channel 112b are arranged at intervals along the axial direction of the valve body 1; the valve core structure 2 includes a first rotating shaft 21 and a second rotating shaft 22, and the second rotating shaft 22 is sleeved on the end of the first rotating shaft 21 away from the water inlet 111, and the first rotating shaft 21 and the second rotating shaft 22 can both rotate relative to the valve body 1, and the first rotating shaft 21 forms a first inner channel 211, and the second rotating shaft 22 forms a second inner channel 221, and a first inner channel 211 is correspondingly connected to a first external channel 112a, and a second inner channel 221 is correspondingly connected to a second external channel 112b. This dual rotating shaft design provides a more complex fluid control path, so that the diverter valve 1000 with switchable flow channel number can control two different groups of fluid channels at the same time. In practical applications, this design can improve the flexibility and accuracy of fluid control, because the two groups of channels can be controlled independently, which is suitable for occasions where multiple fluids need to be controlled simultaneously. In addition, the design of the dual rotating shaft also means that the diverter valve 1000 with switchable number of flow channels can adapt to more complex fluid systems, improving its applicability in industrial applications. In this embodiment, by separately setting the first rotating shaft 21 and the second rotating shaft 22, and controlling both separately, it is convenient to realize the diversion control of the fluid in the through cavity, so as to achieve a better separation effect, meet the requirements of the azimuth control of the fluid, and improve the practicality of the diverter valve 1000 with switchable number of flow channels.

[0034] Specifically, the first outer channel 112a includes four channels, and the second outer channel 112b includes three channels, and each first outer channel 112a and each second outer channel 112b are distributed at intervals along the circumference of the valve body 1. This design enables the diverter valve 1000 with a switchable number of channels to handle more fluid channels, increasing the diversity and flexibility of fluid distribution. In practical applications, this design can enable the diverter valve 1000 with a switchable number of channels to adapt to more complex fluid systems. For example, in a system that needs to control multiple output paths at the same time, this design can ensure that each output path can be independently controlled, thereby improving the control accuracy and efficiency of the entire system. In addition, the design of circumferentially spaced channels allows the fluid to be more evenly distributed to each channel, which helps to reduce the turbulence and pressure loss of the fluid in the valve body 1. This design can also reduce the residence time of the fluid in the valve body 1, reducing the risk of corrosion or blockage that may be caused by fluid retention. In this embodiment, the number of the first outer channels 112a is four, and the number of the second outer channels 112b is three, that is, through this design, the structural effects similar to those of a four-way valve and a three-way valve are respectively formed to realize the diversion control of the fluid. This is equivalent to integrating a four-way valve and a three-way valve into a diverter valve 1000 with switchable flow channels, which not only improves the control effect on the fluid, but also reduces the overall volume of the diverter valve 1000 with switchable flow channels. In the process of use, the diverter valve 1000 with switchable flow channels can also be switched between the three-way valve and the four-way valve by controlling the rotation of the first rotating shaft 21 and the second rotating shaft 22, and both can be used at the same time, which improves the diversified control effect of the diverter valve 1000 with switchable flow channels on the fluid. In other embodiments, the number of the first outer channels 112a and the second outer channels 112b can also be other numbers, which can be selected according to actual needs.

[0035] In an optional embodiment, in order to improve the stability of the diverter valve 1000 with switchable flow channels during use, the outer peripheral wall of the first rotating shaft 21 is formed with a first flow channel groove 212, and the first flow channel groove 212 is extended along the axial direction of the first rotating shaft 21. The outer peripheral wall of the second rotating shaft 22 is formed with a second flow channel groove 222, and the second flow channel groove 222 is extended along the axial direction of the second rotating shaft 22. A first inner channel 211 is located at the bottom wall of a first flow channel groove 212, and a second inner channel 221 is located at the bottom wall of a second flow channel groove 222. This design of the flow channel groove makes the fluid channel clearer and smoother, reduces the resistance to fluid flow, and improves the efficiency of fluid passage. In practical applications, the fluid can flow more directly through the flow channel groove, which can reduce the pressure loss of the fluid in the valve body 1. In addition, the design of the flow channel groove also helps to reduce noise and vibration during fluid flow because the fluid flows more smoothly. Moreover, since the first flow channel groove 212 and the second flow channel groove 222 are respectively opened in the circumferential direction of the first rotating shaft 21 and the second rotating shaft 22 facing the inner wall of the valve body 1, the contact area between the first rotating shaft 21 and the second rotating shaft 22 and the valve body 1 is reduced, so that the friction force at the contact position can be reduced when the two rotate, the resistance generated by the inner wall of the valve body 1 is reduced, and the smoothness of the rotation of the first rotating shaft 21 and the second rotating shaft 22 is improved. This design can also improve the durability of the diverter valve 1000 with switchable flow channels. The flow channel groove can serve as a guide for fluid flow, reduce the direct impact of the fluid on the inside of the valve body 1, and thus reduce wear. At the same time, the design of the flow channel groove also helps to simplify the manufacturing process of the valve core structure 2. The flow channel groove can be directly processed on the outer peripheral wall of the rotating shaft, reducing additional components and assembly steps.

[0036] In an optional embodiment, in order to facilitate the rotational adjustment of the position of the valve core structure 2, the diverter valve 1000 with switchable number of flow channels also includes a limiter, which is arranged on the valve body 1 and abuts against the valve core structure 2 to limit the rotation angle of the valve core structure 2. This design ensures that the valve core does not exceed the preset angle range when rotating, thereby ensuring the accuracy of fluid control. By limiting the rotation angle of the valve core structure 2, excessive rotation caused by improper operation or mechanical failure can be avoided, which may damage the valve core structure 2 or affect the normal flow of the fluid. In addition, the presence of the limiter can also reduce the additional stress caused by excessive rotation of the valve core structure 2, and extend the service life of the valve core structure 2 and the valve body 1. The operational safety of the diverter valve 1000 with switchable number of flow channels is improved, the maintenance cost is reduced, and the stability of the fluid control system is ensured.

[0037] In an optional embodiment, in order to facilitate the disassembly and assembly of the diverter valve 1000 with switchable number of flow channels, the valve body 1 includes a first valve body 11 and a second valve body 12, the first valve body 11 and the second valve body 12 are screwed together to form an installation cavity, the water inlet 111 is provided on the first valve body 11, and the end of the valve core structure 2 away from the water inlet 111 extends out of the second valve body 12. This split design allows each part of the valve body 1 to be manufactured and maintained independently, simplifying the production and maintenance process. If a part of the valve body 1 is damaged, only the part needs to be replaced without replacing the entire valve body 1, which reduces maintenance costs and downtime. In addition, the split design allows more flexible size adjustment and customization to adapt to different installation spaces and application requirements. The threaded connection provides a simple and effective connection method, which ensures the connection strength between the first valve body 11 and the second valve body 12 and ensures that the fluid will not leak at the connection. In addition, by designing the valve body 1 as a split structure, the assembly of the first rotating shaft 21 and the second rotating shaft 22 is facilitated, and the ends of the first rotating shaft 21 and the second rotating shaft 22 that are away from the water inlet 111 extend out of the second valve body 12 to facilitate the connection of a force arm or a driving member, thereby achieving the effect of manual adjustment by human or automatic adjustment by controlling the driving member through a controller, thereby improving the flexibility of rotation adjustment.

[0038] Furthermore, in order to facilitate the rotation of the second rotating shaft 22 relative to the valve body 1, the diverter valve 1000 with switchable flow channel number further includes a first thrust bearing 3, which is sleeved on the second rotating shaft 22, and the two axial sides of the first thrust bearing 3 respectively abut against the second rotating shaft 22 and the inner wall of the valve body 1. The design of the thrust bearing helps to support the second rotating shaft 22, reduce its deformation or displacement under the action of fluid pressure, and ensure the precise alignment of the fluid channel. In a high-pressure system, the valve core may be subjected to a large axial force, which may cause the sealing surface between the second rotating shaft 22 and the valve body 1 to wear or be damaged. The thrust bearing protects the second rotating shaft 22 and the valve body 1 by evenly distributing these forces, thereby extending their service life. In addition, the thrust bearing can also reduce the friction when the second rotating shaft 22 of the valve core rotates, and improve the smoothness and response speed of the operation. The performance and reliability of the diverter valve 1000 with switchable flow channel number under high-pressure environment are improved, ensuring long-term stable operation.

[0039] In an optional embodiment, in order to ensure the smoothness of rotation between the first rotating shaft 21 and the second rotating shaft 22, the first rotating shaft 21 is in a stepped structure, and a second thrust bearing 4 is provided at the step of the first rotating shaft 21, and the second thrust bearing 4 is respectively abutted against the first rotating shaft 21 and the second rotating shaft 22 on both sides of the axial direction. The design of this stepped structure and the second thrust bearing 4 enables the diverter valve 1000 with a switchable number of flow channels to withstand a larger axial force while maintaining the stability of the valve core structure 2. The stepped structure provides additional support points, so that the axial force can be more evenly distributed on the first rotating shaft 21, reducing the risk of damage caused by force concentration. The presence of the second thrust bearing 4 further enhances the resistance to axial force, especially in high pressure or high flow applications. The durability and reliability of the diverter valve 1000 with a switchable number of flow channels are improved, so that it can work stably under a wider range of working conditions, reducing the failure and maintenance requirements caused by axial force. In addition, the design of the second thrust bearing 4 also facilitates reducing the rotational friction between the first rotating shaft 21 and the second rotating shaft 22, reducing the noise and wear generated by the two during rotation, which is beneficial to increasing the service life of the diverter valve 1000 with a switchable number of flow channels.

[0040] Furthermore, a ball bearing 5 is provided on the inner wall of the second rotating shaft 22 facing the first rotating shaft 21, and the inner and outer sides of the ball bearing 5 are respectively in contact with the first rotating shaft 21 and the second rotating shaft 22. The ball bearing 5 reduces friction and wear by reducing direct contact between the first rotating shaft 21 and the second rotating shaft 22, thereby improving the efficiency and life of the rotation between the first rotating shaft 21 and the second rotating shaft 22. In addition, the design of the ball bearing 5 also helps to improve the positioning accuracy of the valve core structure 2, because it can evenly transmit torque and reduce rotation deviation caused by uneven torque.

[0041] In an optional embodiment, in order to achieve axial sealing of the first rotating shaft 21, the diverter valve 1000 with switchable number of flow channels further includes a seal 6 and an end cover 7. The seal 6 is sleeved on the end of the first rotating shaft 21 away from the water inlet 111, the outer periphery of the seal 6 is in contact with the second rotating shaft 22, and the end cover 7 is sleeved on the first rotating shaft 21 and axially presses the seal 6. This sealing design ensures the sealing of the fluid between the valve core structure 2 and the valve body 1, and prevents fluid leakage. The combination of the seal 6 and the end cover 7 provides an effective sealing solution. The design of the seal 6 can also reduce the friction when the valve core rotates and increase the service life of the valve core. The design of the end cover 7 helps to fix the seal 6 to ensure that it does not shift during operation, thereby maintaining the integrity of the seal. This design improves the safety and environmental friendliness of the diverter valve 1000 with switchable number of flow channels, and reduces environmental pollution and operational risks caused by leakage.
