特點(diǎn)

1)可實(shí)現(xiàn)壓力、速度的無(wú)較調(diào)節(jié)，避免了常通的開(kāi)關(guān)式氣閥換向時(shí)的沖擊現(xiàn)象。

2)能實(shí)現(xiàn)遠(yuǎn)程控制和程序控制。

3)與斷續(xù)控制相比，系統(tǒng)簡(jiǎn)化，元件大大減少。

4)與液壓比例閥相比，體積小、重量輕、結(jié)構(gòu)簡(jiǎn)單、成本較低，但響應(yīng)速度比液壓系統(tǒng)慢得多，對(duì)負(fù)載變化也比較敏感。

5)使用功率小、發(fā)熱少、噪聲低。

6)不會(huì)發(fā)生火災(zāi)，不污染環(huán)境。受溫度變化的影響小。

電液比例閥是采用了比例控制技術(shù),介于開(kāi)關(guān)型液壓閥和電液伺服閥之間的-種液壓元件,在工業(yè)生產(chǎn)中獲得了廣泛的應(yīng)用,輸入的電信號(hào)有模擬式和數(shù)字式兩大類(lèi),可以用于控制位置(轉(zhuǎn)角)、速度(轉(zhuǎn)速)、加速度(角加速度)、壓力(壓差)、力(力矩)等參數(shù)。電液比例閥等元件可以組成如下三類(lèi)控制回路和系統(tǒng)

(1)電液比例壓力控制回路和系統(tǒng)。例如:用于帶鋼熱連軋機(jī)卷取機(jī)液壓輔助系統(tǒng)的電液比例壓力控制回路,用于板帶軋機(jī)輥縫控制的液壓推上系統(tǒng)電液比例壓力控制回路,用于帶材卷取設(shè)備恒張力的閉環(huán)電液比例壓力控制回路;

(2)電液比例流量控制回路和系統(tǒng)。例如:用于帶鋼熱連軋機(jī)精軋機(jī)平衡液壓系統(tǒng)的電液比例壓力控制回路,用于機(jī)床微進(jìn)給的電液比例控制回路,用于旋壓機(jī)折板機(jī)同步的電液比例控制回路,用于電梯的電液比例控制回路;

(3)電液比例多參數(shù)控制回路和系統(tǒng)。例如:用于帶鋼熱連軋機(jī)精軋換輥液壓系統(tǒng)的電液比例壓力控制回路,用于液壓缸垂直配置而采用wI型閥芯的比例控制回路,用于熱軋鋼卷步進(jìn)鏈?zhǔn)竭\(yùn)輸機(jī)的速度、加減速度控制回路。

符號(hào) E. 和 W.

4WRLE 型閥門(mén)是一個(gè)帶電氣位置反饋和集成電子元件 (OBE) 的先導(dǎo)式方向控制閥。

結(jié)構(gòu)

閥門(mén)基本構(gòu)成包括 3 個(gè)主要組件：

先導(dǎo)控制閥 (1) 帶有控制閥芯和套筒、復(fù)位彈簧、控制線(xiàn)圈和感應(yīng)式位置傳感器（可選配電子元件保護(hù)膜 (5) 和衰減閥板 (4)）

帶對(duì)中彈簧和位置反饋的主閥 (2)

帶模擬 (6) 或 IO-Link 接口的集成電子元件 (OBE) (3)

功能

當(dāng)集成控制電子元件 (OBE) 被關(guān)閉或處于不活動(dòng)狀態(tài)時(shí)，則先導(dǎo)控制閥的控制閥芯在彈簧作用下置于"故障安全"位置。主閥的控制閥芯位于其彈簧對(duì)中中心位置。

集成控制電子元件 (OBE) 將****控制值與主閥控制閥芯的位置實(shí)際值進(jìn)行比較。在有控制偏差的情況下，將激活控制線(xiàn)圈。由于磁力發(fā)生改變，先導(dǎo)控制閥芯將扺住彈簧進(jìn)行調(diào)節(jié)。

通過(guò)控制剖面激活的流量會(huì)導(dǎo)致主控制閥芯的調(diào)整。主控制閥芯的行程/控制剖面通過(guò)與控制值的比例進(jìn)行調(diào)節(jié)。

先導(dǎo)油可通過(guò)油口 P 從內(nèi)部供給先導(dǎo)控制閥，也可通過(guò)油口 X 從外部供給先導(dǎo)控制閥�？赏ㄟ^(guò)油口 T 從內(nèi)部實(shí)現(xiàn)到油箱的反饋，也可以通過(guò)油口 Y 從外部實(shí)現(xiàn)。

控制線(xiàn)圈斷電

在以下錯(cuò)誤情況下，集成電子元件 (OBE) 使控制線(xiàn)圈斷電，先導(dǎo)控制閥芯將設(shè)置為"故障安全"位置，并將卸載主閥的先導(dǎo)油腔。通過(guò)彈簧操作，主閥控制閥芯將移動(dòng)至中心位置。

低于較小電源電壓

僅在接口 "F1" 處：

低于較小電流控制值 2 mA（包括控制值線(xiàn)的電纜中斷（電流環(huán)））。

僅在接口 "L1" 處：

使能未激活，通訊中斷（看門(mén)狗）

內(nèi)部 IO-Link 發(fā)生故障時(shí)

僅在接口 "C6" 處：

額外使能未激活

衰減閥板 "D"

衰減閥板 (4) 降低集成電子元件上的加速振幅（頻率 >300 Hz）。

注意：

對(duì)于主要為低激勵(lì)頻率 (<300 Hz) 的應(yīng)用，不建議使用衰減閥板。

電子元件保護(hù)膜 "-967"

為避免在集成電子元件 (OBE) 殼體中出現(xiàn)冷凝液，可使用電子元件保護(hù)膜 (5)。

建議用于空氣濕度高且周期溫度變化明顯的外部工業(yè)標(biāo)準(zhǔn)條件（例如室外）。

注意：

具有正遮蓋的先導(dǎo)式三位四通方向控制閥適用于可控制或可調(diào)節(jié)的軸。斷電狀態(tài)下的遮蓋約為控制閥芯行程的 20 %。關(guān)閉電氣電源電壓時(shí)，驅(qū)動(dòng)器可在功能方向 P 至 B 上短時(shí)間加速。

比例控制技術(shù)是在開(kāi)關(guān)控制技術(shù)和伺服控制技術(shù)之間的過(guò)渡技術(shù)，采用比例放大器控制比例電磁鐵，實(shí)現(xiàn)對(duì)比例閥的連續(xù)控制，從而實(shí)現(xiàn)對(duì)液壓系統(tǒng)壓力、流量、方向的無(wú)級(jí)調(diào)節(jié)；但是用比例方向閥進(jìn)行速度控制時(shí)，如果負(fù)載是變化的，那么執(zhí)行元件的速度就會(huì)受負(fù)載變化的影響（負(fù)載小時(shí)速度快，負(fù)載大時(shí)速度慢）；于是在系統(tǒng)設(shè)計(jì)時(shí)，人們引入了壓力補(bǔ)償器，它可以使比例閥閥口的壓差保持恒定，使執(zhí)行元件的速度不受負(fù)載變化的影響。

通過(guò)節(jié)流口的流量只與節(jié)流口的開(kāi)口面積成正比。 對(duì)比例方向閥而言, 進(jìn)油節(jié)流口的開(kāi)口面積與比例方向閥的輸入電流信號(hào)有關(guān),而與負(fù)載的變化無(wú)關(guān)。 亦即升降油缸的供油流量 Q 只與比例方向閥的輸入電流信號(hào)有關(guān),與負(fù)載的變化無(wú)關(guān)。

補(bǔ)償器主要用于節(jié)流調(diào)速系統(tǒng) ，即補(bǔ)償比例閥口的壓差，在定量泵系統(tǒng)中得到了廣泛的應(yīng)用；但這種應(yīng)用不可避免地會(huì)產(chǎn)生一定的溢流損失；如果二通壓力補(bǔ)償器與泵控壓力補(bǔ)償器配合使用，則可以實(shí)現(xiàn)容積節(jié)流調(diào)速。
