Abstract
The invention discloses a structure of a high and low pressure vacuum distribution pipe. The structure comprises a high pressure vacuum pipe and a low pressure vacuum pipe, and further comprises a rotor block and a stator block each provided with multiple separated through holes, wherein the rotor block and the stator block are concentrically arranged and communication and communication interruption can be achieved.
