A switching valve comprises a main valve, a guide valve and a communicating assembly, and the communicating assembly and the main valve are fixedly connected or connected in a limiting mode or are of an integrated structure. The communicating assembly comprises a first connecting part and is provided with at least two hole channels, the main valve comprises a first cavity, one end of each hole channel is communicated with the first cavity, the other end of each hole channel is provided with a first opening in the first connecting part, the pilot valve is provided with a second cavity, and the first opening can be communicated with the second cavity; the guide valve is fixedly connected or in limited connection with the first connecting part; the communicating assembly comprises at least one connecting part, the pilot valve is provided with at least one limiting hole, the limiting hole is sunken into the pilot valve from the periphery of the pilot valve, and at least part of the connecting part is located in the limiting hole and matched with the wall forming the limiting hole. When the pilot valve is connected with the communicating assembly, the connecting part can enable the relative position of the pilot valve and the hole channel of the communicating assembly to be more accurate.
