充液閥的基本結(jié)構(gòu)主要包括閥芯、閥體和驅(qū)動(dòng)閥芯在閥體內(nèi)作相對(duì)運(yùn)動(dòng)的操縱控制機(jī)構(gòu)。閥芯的結(jié)構(gòu)形式多樣;閥體上開(kāi)設(shè)有與閥芯配合的閥體（套）孔或閥座孔，還有外接油管的進(jìn)、出油口；閥芯的操縱控制機(jī)構(gòu)有手調(diào)（動(dòng)）式、機(jī)械式、電動(dòng)式以及液動(dòng)式或電液動(dòng)式等。

液壓閥的基本工作原理是：利用閥芯相對(duì)于閥體的運(yùn)動(dòng)來(lái)控制閥口的通斷及開(kāi)度的大小（實(shí)質(zhì)是對(duì)閥口的流動(dòng)阻尼進(jìn)行控制），實(shí)現(xiàn)對(duì)液流方向、壓力和流量的控制。液壓閥工作時(shí)，所有閥的通過(guò)流量與閥的進(jìn)、出油口間的壓力差以及開(kāi)度的大小間的關(guān)系都符合如下空口壓力流量特性公式G761-3004B
