Abstract：

The article introduces mainly about the mechanical structure of twin\|screw\|stem valve leveler,analyzes stress of the valve and the alignment principle,and discusses about effect of three alignment technical parameter(lowering amount of the valve center,closest distance for two opposed stems,operating pressure of the hydraulic sliding table) on alignment quality and efficiency.And also discusses effect of taper structure of the stem.Finally,explains the difference between mechanical alignment and artificial alignment by pilot production in volume.
