Of course, the number of the branch pipes may be three, four or more, and the specific number may be selected according to the actual application scenario; if the plurality of branch pipes are perpendicular to the pipe housing, the number of the hole passages on the valve core may be one, and if the plurality of branch pipes have a perpendicular pipe housing and a non-perpendicular pipe housing, corresponding hole passages, such as 2 or more than 2, are provided on the valve core, and the number of the hole passages does not exceed the number of the branch pipes at most. The shape of the duct is not particularly limited as long as the main duct and the branch duct can be communicated through the duct.

In this embodiment, the driving device includes a hydraulic cylinder 11, a right end of a piston rod 12 of the hydraulic cylinder is connected to a left end of a connecting rod 13, and a right end of the connecting rod 13 is connected to a left end of the valve core 3. The piston rod 12 and the connecting rod 13 are parallel to the axis of the valve core 3; in the present embodiment, the connecting rod 13 is screwed to the valve element 3, but may be welded to the valve element.

As can be seen from fig. 2, the drive device 11 is connected to the left end of the line housing 2 via a connecting socket 5, which is fastened to the line housing by means of bolts.

In order to detect which branch pipe the material flows out,

position detection switches

61 and 62 are provided on the connecting base in the present embodiment, and it is possible to determine whether the material flows out through the branch pipe B or the branch pipe C by detecting whether the cylinder rod is in the extended state or the retracted state.

The number of position detection switches is of course matched to the number of branch lines.

When the piston rod 12 of the oil cylinder 11 extends, the material in the main pipeline a is guided to flow out of the branch pipeline C through the second pore channel 32 of the valve core 3, as shown in fig. 3 in particular; when the piston rod 12 of the oil cylinder 11 retracts, the material in the main pipeline a is guided to flow out from the opening of the branch pipeline B through the first pore channel 41 of the valve core 3, as shown in fig. 4 in particular; that is, the material entering from the main pipe a can flow out from the branch pipe B, C after being guided by the valve core, so as to realize the arbitrary switching of the pipelines.
