flow channels

102, and 12 inner ports 102a are provided, so that 5

first switching channels

201 and 1 second switching channel 202 may be provided in the valve core 20 to satisfy the switching of different flow channel modes.

Optionally, the first switching channel 201 (i.e. the flow guiding cavity) is arranged in a semi-circular like structure to reduce the medium flow resistance. The second switching passage 202 includes a flow guide inner flow passage 202a and two communication ports 202b, the flow guide inner flow passage 202a is disposed in the valve body 21, and the two communication ports 202b are both located on the outer circumferential surface of the valve body 21 and are communicated with each other through the flow guide inner flow passage 202 a. In this manner, the two communication ports 202b of the second switching passage 202 are made far apart so as to communicate the non-adjacent two inner ports 102a; meanwhile, the flow guide inner flow passage 202a is arranged in the valve core body 21, so that the inner space of the valve core body 21 can be fully utilized. Optionally, the flow guiding inner channel 202a is arranged in an arc-shaped channel to reduce the medium flow resistance.
