?力士樂比例閥 　電液比例閥簡稱比例閥。普通液壓閥只能通過預調(diào)的方式對液流的壓力、流量進行定值控制。但是當設(shè)備機構(gòu)在工作過程中要求對液壓系統(tǒng)的壓力、流量參數(shù)進行調(diào)節(jié)或連續(xù)控制，例如.要求工作臺在工作進給時按慢、快、慢連續(xù)變化的速度實現(xiàn)進給，或按一定精度模擬某個控制曲線實現(xiàn)旅力控制.普通液壓閥則實現(xiàn)不了。這時可以用電液比例閥對液壓系統(tǒng)進行控制。

電液比例閥是一種按輸入的電信號連續(xù)地、按比例地控制液壓系統(tǒng)的液流方向、流量和壓力的閥類。它山電-機械比例轉(zhuǎn)換裝置和液壓控制閥本體兩大部分構(gòu)成.前者將輸入的電信號連續(xù)地按比例地轉(zhuǎn)換為機械力和位移輸出，后者在接受這種機械力和位移之后、按比例連續(xù)地輸出壓力和流量.

電液比例閥的發(fā)展主要有兩個途徑一是用比例電磁鐵取代傳統(tǒng)液壓閥的手動調(diào)節(jié)裝置或取代普通電磁鐵發(fā)展起來的;二是由電液伺服閥簡化結(jié)構(gòu)、降低精度發(fā)展起來的。下面介紹的比例閥均指前者，它是當今比例閥的主流。與普通液壓閥可以互換。
