摘　　要：在分析教材中典型现有基本回路的基础上 ,提出了一种二调速阀串联两工进速度换接新回路 ,本文对其来源、组成、原理、特点及其应用进行了阐述。新回路具有各调速阀可独自调节及能耗低等新特点 (而现有回路则刚好相反 )On basic of analysing hydraulic circuit of nowadays, a new hydraulic circuit has been designed. There are double speed control values and changes of two work speeds in the new hydraulic circuit. This paper introduces origin, formation, principal, feature and application of the new hydraulic circuit of consisting by two speed control valuves series. Every value is adjusted alone. The useless power of new circuit is lower than the circuit nowadays.
