The inventors of the present application noticed that a multi-way valve comprises a valve seat and a valve core. By rotating the valve core, the multi-way valve can combine into a variety of different connection states. However, in the prior art, most multi-way valves adopt a roller-shaped design with a large axial dimension. The torque required for the rotation of the valve core is large. The practicality and adaptability of the multi-way valve need to be improved.

The inventor has found through research that the valve port group of the drum-shaped multi-way valve is arranged axially, and the valve port group refers to at least two valve ports connected by a conducting pipe. Influenced by the valve seat structure, the conducting pipe on the valve core also needs to be arranged axially to connect the valve port group, and due to the limitations of the valve seat and valve core structure, the axial dimension of the drum-shaped multi-way valve is large, and the torque required for the valve core to rotate is also large.

Based on the above problems discovered by the inventors, the inventors have designed a multi-way valve, which includes a valve core and a valve seat. The valve core includes a conducting line. The valve seat is arranged around the valve core and valve ports are arranged at intervals along the circumference of the valve core. The conducting line is used to connect at least two valve ports arranged at intervals in the circumferential direction. The valve core is rotatable relative to the valve seat. Rotating the valve core can change the conducting state between the conducting line and the valve ports to achieve multi-way control, integrate the functions of multiple control valves, simplify the piping system, and reduce system costs; and the valve seat is arranged around the valve core and at least three valve ports are arranged at intervals along the circumference of the valve core, so that the multi-way valve can complete a combination of multiple flow states of adjacent valve ports and non-adjacent valve ports in the circumferential direction, which reduces the space limitation of the multi-way valve in the axial direction and the torque limitation of driving the valve core to rotate, so that the multi-way valve in the present application can be applied to a variety of environments, thereby improving the adaptability and practicality of the multi-way valve.

Please refer to Figures 1 and 2. Figure 1 is a schematic structural diagram of a multi-way valve 1 provided in an embodiment of the present application, and Figure 2 is a cross-sectional view at A-A of the multi-way valve 1 in Figure 1 when it is in a first connected state.

The flow state refers to the connection relationship between the conducting pipeline 21 and the valve port group in the valve core 2, and the valve port group refers to at least two valve ports 31 connected through a conducting pipeline 21. As the valve core 2 rotates, the valve port group connected by each conducting pipeline 21 changes, and the distribution relationship of the valve port groups in the multi-way valve 1 also changes, and the flow state of the multi-way valve 1 also changes accordingly.

The above is only an example. In actual production, the number of valve ports 31 on the valve seat 3 and the combination of the conducting pipes in the valve core 2 can be reasonably selected according to system requirements.

In the technical solution of the embodiment of the present application, the conducting pipeline 21 includes a first pipeline 211 that connects two valve ports 31 and is adjacent to each other in the circumferential direction, and a second pipeline 212 with other valve ports 31 arranged between the two connected valve ports 31. When one conducting pipeline 21 is arranged in a valve core 2, the process difficulty of the valve core 2 can be reduced; when two conducting pipelines 21 are arranged in a valve core 2, compared with the case where only one conducting pipeline 21 is arranged, the combination of the two conducting pipelines 21 can make a single multi-way valve 1 have more different conducting states, so that the multi-way valve 1 can adapt to a variety of different environments, thereby improving the adaptability and practicality of the multi-way valve 1.

In some embodiments, as shown in FIG. 11 , 2n valve ports 31 are provided between two valve ports 31 communicating with the second pipeline 212 , where n≥1.

Each valve port group requires two valve ports 31. When there are an odd number of valve ports 31 between two valve ports 31 connected by a second pipeline 212, this means that there will be a separate valve port 31 in the valve seat 3 that cannot be connected to other valve ports 31. Then this valve port 31 will not play the role of transmitting the medium. As the valve core 2 rotates, there will be an independent valve port 31 that does not have a transmission function in each connected state. This valve port 31 reduces the utilization rate of the multi-way valve 1.

In the technical solution of the embodiment of the present application, 2n valve ports 31 are arranged between the two valve ports 31 connected to the second pipeline 212, where n≥1, so that each valve port 31 of the multi-way valve 1 can be connected to the conducting pipeline 21 in each conducting state, which improves the utilization rate of the multi-way valve 1.

Please refer to FIG. 12 , which is a cross-sectional view of a multi-way valve provided in another embodiment of the present application.

In some embodiments, as shown in FIG. 12 , at least three valve ports 31 can be connected via a conducting line 21 .

At least three valve ports 31 can be connected through a conducting pipe 21 , that is, a valve port group can include multiple valve ports 31 , and the medium flows into the multi-way valve 1 from N valve ports 31 and flows out of the multi-way valve 1 from M valve ports 31 , N≠M≠0.

In the technical solution of the embodiment of the present application, multiple valve ports 31 can be connected through a conducting pipe 21, so that the multi-way valve 1 can integrate the function of a proportional valve, increase the applicable environment of the multi-way valve 1, and improve the adaptability and practicality of the multi-way valve 1.

In some embodiments, as shown in FIG. 12 , the minimum distance L between two adjacent valve ports 31 along the circumferential direction of the valve core 2 is greater than or equal to 2 mm.

Optionally, the minimum distance L between two adjacent valve ports 31 along the circumferential direction of the valve core 2 is 2 mm, 3 mm or 5 mm.

In the technical solution of the embodiment of the present application, the minimum distance L between two adjacent valve ports 31 along the circumferential direction of the valve core 2 is greater than or equal to 2 mm. This reduces the risk of the external flow channels connected to the valve ports 31 being concentrated due to the small distance between the valve ports 31, the media in different flow channels affecting each other, and the working efficiency of the media being reduced, thereby improving the reliability of the multi-way valve 1.

Please refer to FIG. 13 , which is an exploded view of a multi-way valve 1 provided in an embodiment of the present application.

In some embodiments, as shown in FIG. 13 , the multi-way valve 1 further includes an external pipeline 32 , which includes a connecting section 321 and an extension section 322 , wherein the extension section 322 is connected to the valve port 31 through the connecting section 321 , and the extension section 322 is extended away from the valve core 2 .

Optionally, one end of the extension section 322 away from the connection section 321 is provided with a structure such as a thread or a notch for connecting to an external pipeline.

Optionally, the external pipeline 32 and the valve port 31 are detachably connected, and the shape of the port where the extension section 322 is connected to the external pipeline is the same as or different from the shape of the valve port.

Optionally, the extension distances of the extension sections 322 are the same or different.

In the technical solution of the embodiment of the present application, the external pipeline 32 includes a connecting section 321 connected to the valve port 31 and an extension section 322 connected to the connecting section 321 and extending away from the valve core 2. The extension section 322 makes it easier for the multi-way valve 1 to match with the external system, thereby improving the practicality of the multi-way valve 1.
