REXROTH比例減壓閥、Rexroth蓄能器、電磁閥
德國(guó)力士樂(lè)比例閥又稱分配閥，是移動(dòng)式機(jī)械液壓系統(tǒng)基本的元件之一，是能實(shí)現(xiàn)方向與流量調(diào)節(jié)的復(fù)合閥。電液滑閥式比例多路閥是比較理想的電液轉(zhuǎn)換控制元件，它不僅保留了手動(dòng)多路閥的基本功能，還增加了位置電反饋的比例伺服操作和負(fù)載傳感等*的控制手段
REXROTH比例減壓閥、Rexroth蓄能器、電磁閥
REXROTH力士樂(lè)比例閥一般采用兩端承壓面積不等的差徑活塞結(jié)構(gòu)。比例閥不工作時(shí)，差徑活塞2在彈簧3的作用下處于上極限位置，此時(shí)閥門1保持開(kāi)啟，因而在輸入控制壓力P1與輸出壓力P2從零同步增長(zhǎng)的初始階段，總是P1等于P2。但是壓力P1的作用面積A1為π（D2-d2）/4，壓力P2的作用面積A2為πD2/4，因而A2大于A1，故活塞上方液壓作用力大于活塞下方液壓作用力。在P1、P2同步增長(zhǎng)過(guò)程中，當(dāng)活塞上、下兩端液壓作用之差超過(guò)彈簧3的預(yù)緊力時(shí)，活塞便開(kāi)始下移。當(dāng)P1和P2增長(zhǎng)到一定值PS時(shí)活塞2內(nèi)腔中的閥座與閥門1接觸，進(jìn)油腔與出油腔即為隔絕，使比例閥進(jìn)入平衡狀態(tài)。若進(jìn)一步提高P1則活塞將回升，閥門再度開(kāi)啟，油液繼續(xù)流入出油腔而使P2不斷升高，但由于A2大于A1，P2尚未增長(zhǎng)到新的P1值，活塞又下降到平衡位置。在任一平衡狀態(tài)下，差徑活塞的力的平衡方程為：P2路A2=P1路A1+F（此處F為平衡狀態(tài)下的彈簧力）

它是工程機(jī)械分配閥的更新?lián)Q代產(chǎn)品。出于制造成本的考慮和工程機(jī)械控制精度要求不高的特點(diǎn)，一般比例多路閥內(nèi)不配置位移感應(yīng)傳感器，也不具有電子檢測(cè)和糾錯(cuò)功能。所以，閥芯位移量容易受負(fù)載變化引起的壓力波動(dòng)的影響，操作過(guò)程中要靠視覺(jué)觀察來(lái)保證作業(yè)的完成。在電控、遙控操作時(shí)更應(yīng)注意外界干涉的影響。近來(lái)，由于電子技術(shù)的發(fā)展，人們?cè)絹?lái)越多地采用內(nèi)裝的差動(dòng)變壓器（ＬＤＶＴ）等位移傳感器構(gòu)成閥芯位置移動(dòng)的檢測(cè)，實(shí)現(xiàn)閥芯位移閉環(huán)控制。這種由電磁比例閥、位置反饋傳感器、驅(qū)動(dòng)放大器和其它電子電路組成的高度集成的比例閥，具有一定的校正功能，可以有效地克服一般比例閥的缺點(diǎn)，使控制精度得到較大提高。
