D634-371C?R24K02MONSS2電液比例閥簡稱比例閥。普通液壓閥只能通過預(yù)調(diào)的方式對液流的壓力、流量進行定值控制。但是當(dāng)設(shè)備機構(gòu)在工作過程中要求對液壓系統(tǒng)的壓力、流量參數(shù)進行調(diào)節(jié)或連續(xù)控制，例如.要求工作臺在工作進給時按慢、快、慢連續(xù)變化的速度實現(xiàn)進給，或按一定精度模擬某個最佳控制曲線實現(xiàn)旅力控制.普通液壓閥則實現(xiàn)不了。這時可以用電液比例閥對液壓系統(tǒng)進行控制。

電液比例閥是一種按輸入的電信號連續(xù)地、按比例地控制液壓系統(tǒng)的液流方向、流量和壓力的閥類。它山電-機械比例轉(zhuǎn)換裝置和液壓控制閥本體兩大部分構(gòu)成.前者將輸入的電信號連續(xù)地按比例地轉(zhuǎn)換為機械力和位移輸出，后者在接受這種機械力和位移之后、按比例連續(xù)地輸出壓力和流量.VT-NE502-1X/V0/0 0811405152 VT-VARAP1-527-20/V0 0811405153 VT-VARAP1-537-20/V0 0811405154 VT-VARAP1-537-20/V0/5/3V 0811405155 VT-VARAP1-527-20/V0/2STV 0811405156 VT-VARAP1-527-20/V0/3/2VAX 0811405157 VT-VACAP-500-20/V0 0811405158 VT-VACAP-500-20/V0/2CH 0811405162 VT-SSPA1-508-20/V0/1 0811405164 VT-SWMA5-5-1X/V0/0 0811405169 VT-SSBD1-500-10/V0/A 0811405170 VT-SSBD2-500-10/V0/A 0811405171 VT-SSBD2-500-10/V0/A-2F 0811405174 LEITDRPLBESTUECKT 0811405531 HM18-1X/210-V-R/V0/0 0811405532 HM18-1X/350-V-R/V0/0 0811405533 HM18-1X/080-V-S/V0/0 0811405534 HM18-1X/200-N-B/V0/0 0811405535 HM18-1X/350-N-B/V0/0 0811405536 HM18-1X/200-N-S/V0/0 0811405537 HM18-1X/100-N-S/V0/0 0811405538 HM18-1X/350-N-S/V0/0 0811405539 HM18-1X/160-C-B/V0/0 0811405540 HM18-1X/210-V-S/V0/0 0811405541

電液比例閥的發(fā)展主要有兩個途徑一是用比例電磁鐵取代傳統(tǒng)液壓閥的手動調(diào)節(jié)裝置或取代普通電磁鐵發(fā)展起來的;二是由電液伺服閥簡化結(jié)構(gòu)、降低精度發(fā)展起來的。下面介紹的比例閥均指前者，它是當(dāng)今比例閥的主流4WRSE10V50-3X/G24K0/A1V

設(shè)計中就使比例電磁鐵的銜鐵在這段行程中工作。因此。改變線圈中的電流，即可在銜鐵上得到與其成正比的吸力。用比例電磁鐵代替螺旋手柄來調(diào)整液壓閥，就能使輸出樂力或流量與輸人電流對應(yīng)成比例地發(fā)生變化。HMP-013/350
