功能特點:

電(dian)(dian)(dian)(dian)液(ye)比例(li)閥(fa)(fa)(fa)(fa)是閥(fa)(fa)(fa)(fa)內比例(li)電(dian)(dian)(dian)(dian)磁鐵(tie)輸入電(dian)(dian)(dian)(dian)壓(ya)信(xin)號產生相(xiang)應(ying)動(dong)(dong)作，使(shi)工(gong)作閥(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)芯(xin)產生位移，閥(fa)(fa)(fa)(fa)口尺寸發生改變并以(yi)(yi)此完(wan)成與輸入電(dian)(dian)(dian)(dian)壓(ya)成比例(li)壓(ya)力(li)(li)、流量輸出(chu)元(yuan)件。閥(fa)(fa)(fa)(fa)芯(xin)位移也可以(yi)(yi)以(yi)(yi)機(ji)械、液(ye)壓(ya)或電(dian)(dian)(dian)(dian)形式進(jin)行反饋。電(dian)(dian)(dian)(dian)液(ye)比例(li)閥(fa)(fa)(fa)(fa)具(ju)(ju)有(you)(you)(you)(you)形式種類(lei)多樣、容易組成使(shi)用(yong)電(dian)(dian)(dian)(dian)氣(qi)及計(ji)算機(ji)控(kong)制(zhi)各種電(dian)(dian)(dian)(dian)液(ye)系(xi)統(tong)、控(kong)制(zhi)精度高、安裝使(shi)用(yong)靈活以(yi)(yi)及抗污染能(neng)力(li)(li)強等多方面優(you)點(dian)(dian)，應(ying)用(yong)領域日(ri)益拓寬。電(dian)(dian)(dian)(dian)氣(qi)比例(li)閥(fa)(fa)(fa)(fa)快易優(you)自動(dong)(dong)化(hua)選型與收錄(lu)，研(yan)發生產插裝式比例(li)閥(fa)(fa)(fa)(fa)和比例(li)多路閥(fa)(fa)(fa)(fa)充(chong)分考慮到工(gong)程機(ji)械使(shi)用(yong)特點(dian)(dian)，具(ju)(ju)有(you)(you)(you)(you)先導(dao)(dao)控(kong)制(zhi)、負載傳(chuan)感和壓(ya)力(li)(li)補償(chang)等功(gong)能(neng)。它出(chu)現對移動(dong)(dong)式液(ye)壓(ya)機(ji)械整體技術(shu)水平(ping)提(ti)升具(ju)(ju)有(you)(you)(you)(you)重要意義。特別是電(dian)(dian)(dian)(dian)控(kong)先導(dao)(dao)操作、無線(xian)遙控(kong)和有(you)(you)(you)(you)線(xian)遙控(kong)操作等方面展現了其(qi)良好(hao)應(ying)用(yong)前(qian)景。

靈敏度0.2%F.S.

溫度特性±0.12%F.S.

電源電壓0DC24V

輸入信號3電壓型DC0～10V

監控輸出1模擬輸出DC1～5V

環境溫度及使用流體溫度0~50℃

輸出壓力顯示精度±2%F.S.±1digit

輸入信號增大時，1供氣(qi)電磁閥變(bian)為(wei)ON，2排氣(qi)電磁閥變(bian)為(wei)OFF。

因此，供(gong)給壓力通(tong)過(guo)1供(gong)氣電磁閥作用在3先(xian)(xian)導室。并且，3先(xian)(xian)導室的(de)壓力上(shang)升，作用在4膜片上(shang)面。

由此結果，與4膜片連動的5供(gong)氣(qi)閥打開(kai)，一部分供(gong)給壓力(li)成為輸出壓力(li)。

此輸出(chu)壓(ya)力，通過(guo)7壓(ya)力傳感器(qi)反饋到8控制回(hui)路。

在(zai)此，會進行(xing)壓(ya)力(li)調節，直至(zhi)輸出壓(ya)力(li)與輸入信號(hao)成比例(li)，因此，可以穩定(ding)地得到與輸入信號(hao)成比例(li)的輸出壓(ya)力(li)。
