Usually, multiple common water valves such as two-way valves, three-way valves and four-way valves are selected and used in combination, resulting in a large number of water valves in the thermal management system and high costs.

[0039] like Figure 1 As shown, Figure 1 It is a structural schematic diagram of a control valve capable of switching multiple channel flow states disclosed in an embodiment of the present application; on the first aspect, the present application provides a control valve capable of switching multiple channel flow states, comprising: a control valve mechanism 100, a valve core body 200 and a driving mechanism 300, the valve core body 200 being arranged inside the control valve mechanism 100, the driving mechanism 300 being arranged at the upper end of the control valve mechanism 100, and the driving mechanism 300 being used to drive the valve core body 200 to rotate along the axial direction of the control valve mechanism 100 to realize the switching of multiple channel states of the control valve mechanism 100.

[0040] Specifically, the control valve mechanism 100 has an accommodating cavity, and the outer edge of the control valve mechanism 100 is spaced apart with a first interface structure 101 and a second interface structure 102, the first interface structure 101 is provided with a plurality of first interface parts 1011, and the second interface structure is provided with a plurality of second interface parts 1021; the valve core body 200 is arranged in the accommodating cavity, and the valve core body 200 has at least one channel 201; the driving mechanism 300, at least a part of its structure is arranged in the accommodating cavity, so that when driving the valve core body 200 to rotate, the channel 201 connects the two first interface parts 1011, the two second interface parts 1021 and / or the first interface part 1011 with the second interface part 1021.

[0041] Exemplarily, the first interface structure 101 and the second interface structure 102 are arranged on opposite sides of the control valve mechanism 100, wherein the number of first interface parts 1011 set on the first interface structure 101 and the number of second interface parts 1021 set on the second interface structure 102 can be the same or different, and can be set according to actual application conditions.

[0043] In the above-mentioned implementation process, a first interface structure 101 and a second interface structure 102 are set on the outer edge of the control valve mechanism 100, the first interface structure 101 has a plurality of first interface parts 1011, and the second interface structure 102 has a plurality of second interface parts 1021. The valve core body 200 is arranged inside the control valve mechanism 100, and the valve core body 200 has a channel 201.

[0044] Please refer to Figure 1 The first interface structure 101 is protruded from the outer edge of the control valve mechanism 100, and several first interface parts 1011 are staggered and distributed at intervals, which can reduce the size of the control valve mechanism 100 and the valve core body 200, and through the integrated design of several first interface parts 1011, portable installation of the pipeline is achieved.

[0045] Illustratively, one end of the first interface structure 101 is connected to the control valve mechanism 100, and the other end of the first interface structure 101 is provided with the first interface part 1011, and the first interface part 1011 is connected to the accommodating cavity of the control valve mechanism 100. Several first interface parts 1011 can be arranged into an upper and lower structure, and two adjacent first interface parts 1011 are arranged at intervals, and the directions of several first interface parts 1011 are consistent, so that when arranging, there is no need to reserve a large amount of space for the connected pipelines.

The channels 201 can realize the switching of the connection state between two first interface parts 1011, two second interface parts 1021 and / or the first interface part 1011 and the second interface part 1021, thereby improving the integration of parts, reducing the number of parts, and thus reducing the cost investment; it should be noted that in order to facilitate the circulation of fluid and reduce flow resistance, the channel 201 is set to be high at one end and low at the other end.

[0049] like Figure 4-Figure 6 As shown, Figure 4 This is the working mode when the control valve is a six-position seven-way valve. Figure 5 This is the working mode when the control valve is a three-position six-way valve. Figure 6This is the working mode when the control valve is a four-position eight-way valve. Taking a six-position seven-way valve as an example, four first interface parts 1011 are provided, three second interface parts 1021 are provided, and three channels 201 are provided, wherein two channels 201 are provided in an arc shape, and one channel 201 is provided in a straight line.

[0052] In the above implementation process, the first flow channel structure 1012 is set to be an arc shape, and the height of the first flow channel structure 1012 gradually decreases from the first end to the second end, which is beneficial to the circulation of the fluid and also reduces the flow resistance.

[0055] In the above implementation process, the second flow channel structure 1022 is set to be an arc shape, and the height of the second flow channel structure 1022 gradually decreases from the third end to the fourth end, which is conducive to the circulation of the fluid and also reduces the flow resistance.

[0056] Please refer to Figure 3The control valve mechanism 100 includes a control valve body, a seal 103 and a sealing ring 104. The seal 103 is arranged between the control valve body and the valve core body 200 to seal the control valve body and the valve core body 200. The seal 103 is communicated with the first interface part 1011 and the second interface part 1021. The sealing ring 104 is arranged at the upper end of the control valve mechanism 100 to seal the control valve body and the driving mechanism 300. The driving mechanism 300 includes but is not limited to an actuator, and the driving mechanism 300 can be connected to the upper end of the control valve body by fixing parts such as screws.

The sealing ring 104 is arranged at the upper end of the control valve body, which can achieve sealing between the control valve body and the driving mechanism 300, thereby ensuring the normal operation of the control valve.
