液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號(hào)后,相應(yīng)輸出調(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件,也是功率放大元件,它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘?hào)轉(zhuǎn)換為大功率的液壓能(流量和壓力)輸出。在電液伺服系統(tǒng)中,它將電氣部分與液壓部分連接起來,實(shí)現(xiàn)電液信號(hào)的轉(zhuǎn)換與液壓放大。電液伺服閥是電液伺服系統(tǒng)控制的核心。
液控伺服閥是在伺服系統(tǒng)中將電信號(hào)輸入轉(zhuǎn)換為功率較大的壓力或流量壓力信號(hào)輸出的執(zhí)行元件。它是一種電液轉(zhuǎn)換和功率放大元件。伺服閥的靈敏度高,快速性好,能將很小的電信號(hào)(例如10毫安)轉(zhuǎn)換成很大的液壓功率(如幾十匹馬力以上),可以驅(qū)動(dòng)多種類型的負(fù)載。過去人們曾把噴嘴檔板閥、射流管或滑閥伺服馬達(dá)等液壓放大裝置都列入伺服閥范圍內(nèi)。20世紀(jì)70年代以來,伺服閥一般僅指電液伺服閥。

伺服閥的驅(qū)動(dòng)裝置是力馬達(dá)或力矩馬達(dá).閥體兼作閥套。
驅(qū)動(dòng)裝置不同.所以近些年出現(xiàn)了比例伺服閥。
比例閥一般最高幾十Hz,伺服閥中位沒有死區(qū),伺服閥對(duì)液壓油液的要求更高.性能參數(shù)不同;否則容易堵塞,
用來控制流量和流向,比例閥要求低一些.比例閥有中位死區(qū);
比例閥和伺服閥的區(qū)別主要體現(xiàn)在以下幾點(diǎn):
逐漸向伺服閥靠近,
比例換向閥屬于比例閥的一種,滯環(huán)、中位死區(qū)、頻寬、過濾精度等特性不同.閥的額定壓降不同;比例換向閥具有與普通換向閥相似的中位機(jī)能,
而比例伺服閥性能介于伺服閥和比例閥之間,因此應(yīng)用場合不同,伺服閥和伺服比例閥采用閥芯+閥套的結(jié)構(gòu)。中位機(jī)能種類不同.其它結(jié)構(gòu)的比例閥主要應(yīng)用在開環(huán)控系統(tǒng)及閉環(huán)速度控制系統(tǒng);因?yàn)楸壤y的性能越來越好;2伺服閥的頻響(響應(yīng)頻率)更高。閥芯結(jié)構(gòu)及加工精度不同.伺服閥與比例閥之間的差別并沒有嚴(yán)格的規(guī)定。
