4WRA6V30-22/G24N9K4/V-589力士樂比例閥

4WRA6V30-22/G24N9K4/V-589力士樂比例閥

功用：正向流通，反向受控流通

結(jié)構(gòu)：普通單向閥 液控裝置

工作原理：K不通壓力油，工作方式同普通單向閥；K通壓力油，閥口打開，可以反向流通

應(yīng)用：∵液控單向閥具有良好的反密封性

常用于保壓、鎖緊和平衡回路

圖形符號含義：

1、 位——用方格表示，幾位即幾個方格

2 、通——┴ 、┬ 箭頭首尾和堵截符號與一個方格有幾個交點即為幾通。

3 、油口有固定方位和含義，p——進油口(左下）， T——回油口（右下） ，A.B——與執(zhí)行元件連接的工作油口（左、右上）。

4 、彈簧——W、M，畫在方格兩側(cè)

5 、常態(tài)位置 ——原理圖中，油路應(yīng)該連接在常態(tài)位置。如三位閥在中間一格。

滑閥的中位機能：即滑閥處于常態(tài)時的狀態(tài)，有M型，H型，O型，P型，M型等。

 

電液比例閥是比例控制系統(tǒng)中的主要功率放大元件,按輸入電信號指令連續(xù)地成比例地控制液壓系統(tǒng)的壓辦流量等參數(shù)。與伺 服控制系統(tǒng)中的伺服閥相比,在某些方面還有一-定的性能差距(主要性能比較如表1所示),但它顯著的優(yōu)點是抗污染能力強,大大地減少了由污染而造成的工作故障,提高了液壓系統(tǒng)的工作穩(wěn)定性和可靠性。另一方面比例閥的成本比伺服閥低，結(jié)構(gòu)也簡單,已在許多場合獲得廣泛應(yīng)用。

 

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)用也為普遍;

(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電機力馬達和力矩馬達比例電磁鐵等形式。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)用廣泛的比例電磁鐵是耐高壓直流比例電磁鐵。

1.結(jié)構(gòu)和功能原理

該二位四通和三位四通比例方 向閥為直控,板式結(jié)構(gòu);由比例電磁操作,比例電磁.帶中心螺紋,圈可單獨拆卸,電磁的控制可通過外部放大器( WRA型)或內(nèi)置的放大器(WRAE型)實現(xiàn)。

結(jié)構(gòu):

該閥由下列部分組成:

帶安裝底面的閥體( 1 )

帶彈簧(3和4)的控制閥芯(2 )

帶中心螺紋的電磁鐵( 5和6 )

位移傳感器(7 )

可選帶內(nèi)置放大器( 8 )

機械零位調(diào)整(9 ),

工作原理:

電磁鐵(5和6 )不帶電時,對中彈簧(3和4 )將控制閥芯(2 )保持在中位

比例電磁鐵得電被激勵后,會直接推動控制閥芯( 2),例如:控制電磁"b" (6 )被激勵，控制閥芯(2)被推向左側(cè),位移與輸入電信號成比例,這時,P口至A口及B口至T口通過閥芯與閥體形成的節(jié)流溝通并具有漸進的流量特性。電磁鐵( 6 )失電控制.閥芯(2)被對中彈簧(3)重新推回中位。

在電磁鐵失電的情況下,閥芯( 2 )在電磁跌復(fù)位彈簧的作用保持在機械中位。這對機能符號”V”的閥芯來說,與液壓中位無關(guān)!當(dāng)閥用于閉環(huán)控制而關(guān)閉時,閥芯則置于液壓中位。

必須避免回油管路中的油全部排空, 必要時在回路中安裝背壓閥(背壓約2 bar)。

力士樂REXROTH三位四通比例方向閥，直接操作、集成式放大版（OBE）4WREEM

液壓比例控制系統(tǒng)

以比例控制元件完成動力與運動方向控制，分為比例壓力閥、比例流量閥、比例方向閥及比例方向流量閥，可為模擬量輸入或數(shù)字量輸入，視是否帶反饋分為開環(huán)控制與閉環(huán)控制，一般獲得頻率不是很高(10HZ)以內(nèi)，高頻響閥可實現(xiàn)較高頻率。

若精度要求不高可考慮使用電液比例控制系統(tǒng)，一般電液比例控制系統(tǒng)可達至以下精度

位置精度- 3 mm

速度精度帶壓力補償器- 3%

加減速斜坡時間-0.5秒

壓力帶位移傳感器的產(chǎn)品-比例壓力閥設(shè)定的0.3% (如壓力設(shè)定為200bar,精度可達0.6bar)

一般的多驅(qū)動器液壓系統(tǒng)皆要求流量及壓力控制，提供比例壓力及流量控制系統(tǒng)

開環(huán)式比例壓力及流量控制可用于定量泵及變量泵系統(tǒng)。

速度和流量比例控制的分別是:

流量控制只控制供油量,并不控制驅(qū)動元件的運動方向;

若系統(tǒng)負(fù)載及變速要求高，則要使用速度控制系統(tǒng)。

速度比例控制多用于自動化控制、注塑機、壓力機等
