Differential pressure reducing device and vertical mill pressurizing station applying same

The utility model relates to a differential pressure reducing device and a vertical mill pressurizing station applying the same, and belongs to the technical field of reducing the differential pressure when a vertical mill pressurizing oil cylinder stops oil supply and pressure maintaining, the differential pressure reducing device comprises a pipe body, and the pipe body comprises an inlet pipe, a reducer pipe and an outlet pipe which are communicated in sequence; the reducer pipe comprises a pressure storage pipe and buffer pressure pipes symmetrically arranged on the two sides of the pressure storage pipe, and the diameter of the pressure storage pipe is larger than that of the buffer pressure pipes on the two sides. Through the arrangement of the reducer pipe, hydraulic oil flows into the buffer pipe from the inlet pipe to achieve pressure accumulation. 本申请涉及一种减小压差装置及应用该装置的立磨加压站，属于立磨加压油缸停止供油保压时减小压力差的技术领域，其包括管体，所述管体包括依次连通的进口管、变径管及出口管，所述变径管包括蓄压管及对称设置在所述蓄压管两侧的缓冲压力管，所述蓄压管的直径大于两侧所述缓冲压力管。本申请通过变径管的设置，液压油从进口管流入到缓
