4WRTE16E1-125L-4X/6EG24K31/A1M比例方向閥

結(jié)構(gòu)原理

輸入信號加大，供氣用電磁閥先導(dǎo)閥1換向，而排氣用電磁先導(dǎo)閥7處于復(fù)位狀態(tài)，則供氣壓力從SUP口通過閥1進(jìn)入先導(dǎo)室5，先導(dǎo)室壓力上升，氣壓力作用在膜片2的上方，則和膜片2相連的供氣閥芯4便開啟，排氣閥芯3關(guān)閉，產(chǎn)生輸出壓力。此輸出壓力通過壓力傳感器6反饋至控制回路8。在這里，與目標(biāo)值進(jìn)行快速比較修正，知道輸出壓力與輸入信號成一定比例為止，從而得到輸出壓力與輸入信號的變化成比例的變化。由于沒有噴嘴擋板機(jī)構(gòu)，故閥對雜質(zhì)不敏感，可靠性高。

 

特點(diǎn)

1)可實(shí)現(xiàn)壓力、速度的無較調(diào)節(jié)，避免了常通的開關(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)簡單、成本較低，但響應(yīng)速度比液壓系統(tǒng)慢得多，對負(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。

比例閥三種形態(tài)

（1）電磁式 電磁式是指采用比例電磁鐵作為電氣一機(jī)械轉(zhuǎn)換元件的比例閥，比例電磁鐵將輸入的電流信號轉(zhuǎn)換成力、位移機(jī)械信號輸出．進(jìn)而控制壓力、流量及方向等參數(shù)。

（2）電動(dòng)式 電動(dòng)式是指采用直流伺服電動(dòng)機(jī)作為電氣一機(jī)械轉(zhuǎn)換元件的比例閥，直流伺服電動(dòng)機(jī)將輸入的電信號．轉(zhuǎn)換成旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)速，再經(jīng)絲桿螺母、齒輪齒條或齒輪凸輪等減速裝置和變換機(jī)構(gòu)，輸出力與位移，進(jìn)一步控制液壓參數(shù)。

（3）電液式 電液式是指采用力矩馬達(dá)和噴嘴擋板的結(jié)構(gòu)為先導(dǎo)控制級的比例閥。對力矩馬達(dá)輸入不同的電信號，并通過同它連接在一起的擋板（有時(shí)力矩馬達(dá)的銜鐵就是擋板）輸出位移或角位移，改變擋板和噴嘴之間的距離，使噴嘴噴出的油液流阻產(chǎn)生變化，進(jìn)而控制輸小參數(shù)。

比例閥是氣流只能一個(gè)方向流動(dòng)而不能反向流動(dòng)的方向控制閥。其工作原理與液壓單向閥一樣。壓縮空氣從P口進(jìn)入，克服彈簧力和摩擦力使單向閥閥口開啟，壓縮空氣從P流至A；當(dāng)P口無壓縮空氣時(shí)，在彈簧力和A口（腔）余氣力作用下；閥口處于關(guān)閉狀態(tài)，使從A至P氣流不通。

比例閥應(yīng)用于不允許氣流反向流動(dòng)的場合，如空壓機(jī)向氣罐充氣時(shí)，在空壓機(jī)與氣罐之間設(shè)置一單向閥，當(dāng)空壓機(jī)停止工作時(shí)，可防止氣罐中的壓縮空氣回流到空壓機(jī)。比例閥還常與節(jié)流閥、順序閥等組合成比例閥使用。

4WRD E..型比例伺服控制閥(高頻響閥)

結(jié)構(gòu)和功能

4WRDE型閥是三級高頻響方向閥。該閥可用于開環(huán)控制或閉環(huán)調(diào)節(jié)液流的大小和方向，但主要用于閉環(huán)調(diào)節(jié)回路中。

閥主要由下列部分組成:

1.二級先導(dǎo)控制閥由力矩馬達(dá)( 1 )和由噴嘴擋板閥構(gòu)成的液壓放大器( 5),和用作流量放大級的閥芯襯套組件(6 )(用以控制第三級(7 ))組成。

2.第三級(7)用于流量控制。

3.感應(yīng)式位移傳感器( 8),連接第三級主閥芯( 10)的磁芯(9 )

通過內(nèi)置電子放大器實(shí)現(xiàn)閥閉環(huán)控制信號邏輯連接,位置檢測系統(tǒng)反饋,和先導(dǎo)閥的控制。

給定值/實(shí)際值比較得到的差動(dòng)電壓經(jīng)過電子控制器放大, 并作為控制偏差量傳遞到閥的一級。這個(gè)信號推動(dòng)兩個(gè)控制噴嘴( 3.1, 3.2) 之間的擋板( 2)因而在兩個(gè)控制腔(11.1.11.2)產(chǎn)生了壓差�？刂崎y芯(4 )因此被推動(dòng),并通過相應(yīng)的液流流到彈簧腔(12.1or12.2)閥芯(10)和帶磁芯(9)的位移傳感器(8)-直運(yùn)動(dòng),直到實(shí)際值和給定值信號再一次相等。在控制條件下;主閥芯( 10 )一直被保持在給定值所對應(yīng)的位置。

閥芯行程和給定值成正比。通過閥芯( 10 )相對于控制邊( 13 )的位置,形成相應(yīng)的與流量成正比的閥口開度。

閥的動(dòng)態(tài)特性通過電子放大器優(yōu)化。電子放大器內(nèi)置于閥上(振蕩器,解調(diào)器)

零點(diǎn)調(diào)節(jié)由廠家預(yù)先設(shè)定,通過閉環(huán)控制電子放大器內(nèi)的電位器, 零點(diǎn)能在名義行程士10%范圍內(nèi)調(diào)整。移去閥蓋尾部的插頭,可以對內(nèi)置閉環(huán)電子放大器進(jìn)行操作。

力士樂REXROTH三位三通方向高響應(yīng)閥，先導(dǎo)操作，電感位置傳感器3WRCBH

二通插裝閥與普通液壓閥的功能相同，都是用來控制液壓系統(tǒng)工作介質(zhì)的壓力、流量和流動(dòng)方向的。二通插裝閥由插入元件、先導(dǎo)元件、控制蓋板和插裝塊體四部分組成。插入元件主要由閥芯、閥套、彈簧和密封件組成，圖1為其示意圖。控制蓋板上,根據(jù)插裝閥的不同控制功能，安裝有相應(yīng)的先導(dǎo)控制級元件，以實(shí)現(xiàn)對液壓系統(tǒng)壓力、流量和方向的控制,插裝塊體則既是嵌入插入元件及安裝控制蓋板的基礎(chǔ)閥體，又是主油路和控制油路的通道體。
