This utility model discloses an automatic diverting valve for vacuum pipelines, relating to the field of fluid control technology. The utility model includes a main pipeline with a flow-direction changing mechanism and a disassembly mechanism on its outer wall. By incorporating a valve plate, when the fluid direction needs to be changed, a controller starts a motor, which rotates a threaded rod.
