带自封装置的液压换向转阀的研究

Research of Hydraulic Reversing Valve with Self-installation

传统的液压换向转阀、配油阀口之间采用平面间隙密封结构,液体压力增大时,容易发生内泄漏现象。本文介绍一种带自封装置的液压换向转阀,利用液压力平衡的原理,实现配油阀口之间的间隙转移到非工作面之间,避免了液体的内泄漏,使用安全可靠。

Slit seal between valve ports is adopted in existing hydraulic reversing valves, so internal leakage will happen easily with the increase of liquid pressure A new hydraulic reversing valve with selfsealing structure is introduced in this article Working according to principles of balance of hydraulic pressure to realize the valve port slit shift to nomwork plane and avoid internal leakage If s safe and reliable to use
