For those of ordinary skill in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0035] At present, when connecting the pipeline of the vehicle-mounted air conditioning system, a plurality of three-way valves or a plurality of four-way valves are combined to adjust the communication state of the pipeline, so as to realize the flow of medium in different circuits. Since the number of three-way valves and four-way valves is large, each three-way valve needs to be adjusted, which is inconvenient to operate and low in efficiency. Moreover, the installation space required by multiple valves is large, which is not conducive to layout.

[0036] In view of this, the designer designs a control valve, which can realize the adjustment of the connection state of different pipelines through one valve, is convenient and flexible to operate, and is high in efficiency. Moreover, one valve requires small installation space, which is beneficial to layout.

[0037] Please refer to Figure 1 In the embodiment, the control valve comprises a valve seat 100 and a valve core 200. Eight interfaces are arranged on the valve seat 100, and the eight interfaces are divided into two groups. Four interfaces in the same group are arranged at intervals in the circumferential direction of the preset axis, and the two groups of interfaces are arranged at intervals in the extension direction of the preset axis. The valve core 200 is provided with a plurality of flow channels, and the valve core 200 is rotatably connected with the valve seat 100, for adjusting the connection state of the eight interfaces; wherein, when the eight interfaces are in the connection state, the eight interfaces are divided into four groups, and two interfaces in each group are connected through the corresponding flow channel.

[0038] The control valve provided in the embodiment can realize the adjustment of the connection state of the eight interfaces by rotating the valve core 200, so as to ensure that the eight interfaces can always be kept in the state of two-by-two interface connection, that is, when the control valve is in the working process, there are always four channels in the connection state, the use range is wide, and the control valve can adapt to different scene requirements, and only the valve core 200 needs to be rotated, so the operation is convenient and flexible, and the efficiency is high. Since the control valve integrates the functions of multiple three-way valves and multiple four-way valves, the overall structure is compact, the volume is small, the occupied space is small, and the layout is beneficial. Moreover, the eight interfaces on the valve seat 100 of the control valve are arranged in double rows, the longitudinal space is reasonably utilized, the interfaces are more concentrated compared with the eight interfaces arranged in a ring shape, the pipeline is convenient to butt joint, the space occupied after the pipeline butt joint is small, and the pipeline layout is beneficial.
