4WREE10E50-2X/G24K31/A1V比例換向閥

4WREE10E50-2X/G24K31/A1V比例換向閥 德國原裝博世力士樂REXROTH比例方向閥 比例換向閥

舉例型號：4WREE10E75-2X/G24K31/A1V  

4WRE →直控式比例換向閥，板式結(jié)構(gòu)

E    →帶內(nèi)置放大器（無E可通過連接外部放大器）

10   → 10通經(jīng)（也有6通經(jīng)等）

E    →機能符號（也有E1-、V、W、W1-、EA、WA等）

75   →閥的壓差為10bar時的額定流量(NS10) 75 L/min 

       （也有(NS6)08、16、32，(NS10)25、50、75等）

2X   →20至29系列（20至29：安裝和連接尺寸不變）

G24  →24V直流電源

K31  →帶符合E DIN 43 563-AM6-3的插座,不帶插頭 插頭       需單獨訂貨(K4指帶符合DIN 43 650-AM2的插座 不       帶插頭)

A1   →WREE型A1或F1接口：給定值輸入±10 V(F1=給定值        輸入4至20mA)

V    →氟橡膠矩形密封圈 符合DIN 51 524 標(biāo)準(zhǔn)的液壓油       （HL,HLP）

比例閥按功能分為三大類

(1)比例壓力閥。有溢流閥減壓閥,分別有直動和先導(dǎo)兩種結(jié)構(gòu);可連續(xù)地或按比例地遠(yuǎn)程控制其輸出油液壓力;

(2)比例換向閥。有直動和先導(dǎo)兩種結(jié)構(gòu),直動閥有帶位移傳感器和不帶位移傳感器兩類。由于使用了比例電磁鐵閥芯不僅可以換位，而且換位的行程可以連續(xù)地或按比例地變化。因而連通油口間的通流面積也可以連續(xù)或按比例地變化。所以比例換向閥不僅能夠控制執(zhí)行元件的方向而且能夠控制其速度。因為這個原因比例閥中的比例換向閥應(yīng)用也普遍;

(3)比例流量閥。有比例調(diào)速閥和比例溢流流量控制閥,可連續(xù)地或按比例地遠(yuǎn)程控制其輸出流量。

比例閥的輸入單元是電-機械轉(zhuǎn)換器,它將輸入的電信號轉(zhuǎn)換成機械量轉(zhuǎn)換器有伺服電機和步進(jìn)電機力馬達(dá)和力矩馬達(dá)比例電磁鐵等形式。但常用的比例閥大都采用了比例電磁鐵，比例電磁鐵根據(jù)電磁原理設(shè)計,能使其產(chǎn)生的機械量(力或力矩和位移)與輸入電信號(電流)的大小成比例,再連續(xù)地控制液壓閥閥芯的位置，進(jìn)而實現(xiàn)連續(xù)地控制液壓系統(tǒng)的壓力方向和流量。比例電磁鐵的結(jié)構(gòu)，它由線圈、銜鐵推桿等組成,當(dāng)有信號輸入線圈時,線圈內(nèi)磁場對銜鐵產(chǎn)生作用力,銜鐵在磁場中按信號電流的大小和方向成比例連續(xù)地運動,再通過固連在一起的銷釘帶動推桿運動,從而控制滑閥閥芯的運動。應(yīng)用的比例電磁鐵是耐高壓直流比例電磁鐵。

型號 4WREE...-2X/...

在閥板設(shè)計中兩位四通及三位四通比例方向閥用作直動式設(shè)備。通過帶對中螺紋和可拆卸線圈的比例電磁鐵進(jìn)行操作。通過集成電子元件控制線圈。

設(shè)置：

閥門的基本構(gòu)成包括：

帶連接面的殼體 (1)

帶有壓縮彈簧（3 和 4）與彈簧座（5 和 6）的控制閥芯 (2)

帶對中螺紋的線圈（7 和 8）

位置傳感器 (9)

集成電子元件 (13)

可通過 Pg7 進(jìn)行電氣零電位調(diào)節(jié) (12)

功能：

線圈（7 和 8）斷電后，位于彈簧座（5 和 6）之間的壓縮彈簧（3 和 4）可將控制閥芯 (2) 置于中心位置

可通過控制比例電磁鐵（例如，線圈“b”(8)）直接操作控制閥芯 (2)

→ 控制閥芯 (2) 與電氣輸入信號成比例地向左移動

→ 通過具有漸進(jìn)

流體特性的節(jié)流橫截面，進(jìn)行從 P 到 A 及從 B 到 T 的連接

關(guān)閉線圈 (8)

→ 控制閥芯 (2) 在壓縮彈簧 (3) 的作用下返回至中心位置

在斷電狀態(tài)下，線圈的復(fù)位彈簧使得控制閥芯 (2) 保持在機械中心位置。使用帶有符號“V”的控制閥芯時，此位置與液壓中心位置不對應(yīng)！電動閥控制環(huán)關(guān)閉時，控制閥芯將位于液壓中心位置。

重要注意事項：

PG 裝配 (11) 不得打開。位于下方的調(diào)節(jié)螺母的機械調(diào)節(jié)已禁用，該操作會損壞閥門！

帶兩個閥芯位置的閥門：（型號 4WREE...A...）

基本上，此型號閥的功能與帶三個閥芯位置的閥門功能相對應(yīng)。但是，此雙閥芯位置閥僅配有線圈“a”(7)。它配有保護(hù)塞 (10) 來代替第二個比例電磁鐵。

注意：

由于設(shè)計原理，閥內(nèi)固有內(nèi)部泄漏，泄漏量可能隨著使用年限而增加。

注意：

不得讓油箱管路排空運行。在相應(yīng)的安裝條件下，必須安裝一個預(yù)載閥（預(yù)載壓力約為 2 bar）。
