美國(guó)威格士VICKERS比例控制閥、*/上海一級(jí)
美國(guó)威格士VICKERS比例控制閥主要用於開(kāi)回路控制（open loop control）;比例控制閥的輸出量與輸入信號(hào)成比例關(guān)系,且比例控制閥內(nèi)電磁線圈所產(chǎn)生的磁力大小與電流成正比.在傳統(tǒng)型式的液壓控制閥中,只能對(duì)液壓進(jìn)行定值控制,例如:壓力閥在某個(gè)設(shè)定壓力下作動(dòng),流量閥保持通過(guò)所設(shè)定的流量,方向閥對(duì)於液流方向通/斷的切換.因此這些控制閥組成的系統(tǒng)功能都受到一些限制,隨著技術(shù)的進(jìn)步,許多液壓系統(tǒng)要求流量和壓力能連續(xù)或按比例地隨控制閥輸入信號(hào)的改變而變化.液壓伺服系統(tǒng)雖能滿足其要求,而且精度很高,但對(duì)於大部分的工業(yè)來(lái)說(shuō),他們并不要求系統(tǒng)有如此高的品質(zhì),而希望在保證一定控制性能的條件下,同時(shí)價(jià)格低廉,工作可靠,維護(hù)簡(jiǎn)單,所以比例控制閥就是在這種背景下發(fā)展起來(lái)的.
比例控制閥可分為壓力控制閥,流量控制及方向控制閥三類.
壓力控制閥:用比例電磁閥取代引導(dǎo)式溢流閥的手調(diào)裝置便成為引導(dǎo)式比例溢流閥,其輸出的液壓壓力由輸入信號(hào)連續(xù)或按比例控制.
流量:用比例電磁閥取代節(jié)流閥或調(diào)速閥的手調(diào)裝置而以輸入信號(hào)控制節(jié)流閥或調(diào)速閥之節(jié)流口開(kāi)度,可連續(xù)或按比例地控制其輸出流量.故節(jié)流口的開(kāi)度便可由輸入信號(hào)的電壓大小決定.
方向控制閥:比例電磁閥取代方向閥的一般電磁閥構(gòu)成直動(dòng)式比例方向閥,其滑軸不但可以換位,而且換位的行程可以連續(xù)或按比例地變化,因而連通油口間的通油面積也可以連續(xù)或按比例地變化,所以比例方向控制閥不但能控制執(zhí)行元件的運(yùn)動(dòng)方向外,還能控制其速度.
