The fluid channel 511 is communicated with the interior of the first tube body 2, and the switching port 512 is communicated with the fluid channel 511. The valve port regulating member 5 moves along the axial direction of the first tube body 2 so that the switching port 512 is communicated with the first opening 21 or the second opening 22, so that the first tube body 2 is selectively communicated with the second tube body 3 or the third tube body 4. It can be understood that the valve port regulating member 5 blocks both the first opening 21 and the second opening 22 on the first tube body 2, and the first tube body 2 can be communicated with the second tube body 3 or the third tube body 4 only when the switching port 512 on it overlaps with one of the first opening 21 or the second opening 22.

[0044] In one embodiment, a first thread 23 is further provided on the inner wall of the first tube body 2, and a second thread 521 cooperating with the first thread 23 is provided on the outer wall of the valve port adjusting member 5.

The switch valve body 1 can be a common switch valve structure in the field, such as a ball valve, a gate valve, etc. The shell of the switch valve body 1 can be formed with the first tube body 2 by welding. Here, it should be noted that Figure 3 The specific structure inside the switch valve body 1 is not shown.

[0057] Furthermore, a corresponding limit portion and connecting thread may be provided on the outer wall of the end portion of the fourth tube body connected to the first inlet 11 to facilitate connection with the refrigerant outlet pipeline of the air conditioner outdoor unit.

[0058] In one embodiment, the axis of the first inlet 11 and the axis of the first outlet 12 are in the same plane and the included angle is 120-135°.

[0059] In one embodiment, if Figure 1-Figure 3 As shown, the projections of the second tube body 3 and the third tube body 4 along the axis of the first tube body 2 overlap. That is, the second tube body 3 and the third tube body 4 have the same orientation, and only have different positions in the axial direction of the first tube body 2.
