Rexroth比例閥的用途:
Rexroth比例控制閥的輸出量(流量、壓力)可以按照輸入信號的變化規律連續成比例地進行調節。通常是采用比例電磁鐵將輸入的電信號轉換成力或者閥的機械位移量進行控制。
主要用于成比例的控制液壓系統中的壓力或者流量。
Rexroth比例閥簡介:
Rexroth電液比例閥簡稱比例閥。普通液壓閥只能通過預調的方式對液流的壓力、流量進行定值控制。但是當設備機構在工作過程中要求對液壓系統的壓力、流量參數進行調節或連續控制,例如.要求工作臺在工作進給時按慢、快、慢連續變化的速度實現進給,或按一定精度模擬某個*控制曲線實現旅力控制.普通液壓閥則實現不了。這時可以用電液比例閥對液壓系統進行控制。
Rexroth電液比例閥是一種按輸入的電信號連續地、按比例地控制液壓系統的液流方向、流量和壓力的閥類。它山電-機械比例轉換裝置和液壓控制閥本體兩大部分構成.前者將輸入的電信號連續地按比例地轉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、按比例連續地輸出壓力和流量.
電液比例閥的發展主要有兩個途徑一是用比例電磁鐵取代傳統液壓閥的手動調節裝置或取代普通電磁鐵發展起來的;二是由電液伺服閥簡化結構、降低精度發展起來的。下面介紹的比例閥均指前者,它是當今Rexroth比例閥的主流。與普通液壓閥可以互換。
Rexroth電液比例閥是閥內比例電磁鐵輸入電壓信號產生相應動作,使工作閥閥芯產生位移,閥口尺寸發生改變并以此完成與輸入電壓成比例壓力、流量輸出元件。閥芯位移也可以以機械、液壓或電形式進行反饋。電液比例閥具有形式種類多樣、容易組成使用電氣及計算機控制各種電液系統、控制精度高、安裝使用靈活以及抗污染能力強等多方面優點,應用領域日益拓寬。近年研發生產插裝式比例閥和比例多路閥充分考慮到工程機械使用特點,具有先導控制、負載傳感和壓力補償等功能。它出現對移動式液壓機械整體技術水平提升具有重要意義。特別是電控先導操作、無線遙控和有線遙控操作等方面展現了其良好應用前景。 
2 工程機械電液比例閥種類和形式 
電液比例閥包括比例流量閥、比例壓力閥、比例換向閥。工程機械液壓操作特點,以結構形式劃分電液比例閥主要有兩類:一類是螺旋插裝式比例閥(screwin cartridge proportional valve),另一類是滑閥式比例閥(spool proportional valve)。 
螺旋插裝式比例閥是螺紋將電磁比例插裝件固定油路集成塊上元件,螺旋插裝閥具有應用靈活、節省管路和成本低廉等特點,近年來工程機械上應用越來越廣泛。常用螺旋插裝式比例閥有二通、三通、四通和多通等形式,二通式比例閥主比例節流閥,它常它元件一起構成復合閥,對流量、壓力進行控制;三通式比例閥主比例減壓閥,也是移動式機械液壓系統中應用較多比例閥,它主對液動操作多路閥先導油路進行操作。利用三通式比例減壓閥可以代替傳統手動減壓式先導閥,它比手動先導閥具有更多靈活性和更高控制精度。可以制成如圖1所示比例伺服控制手動多路閥,不同輸入信號,減壓閥使輸出活塞具有不同壓力或流量進而實現對多路閥閥芯位移進行比例控制。四通或多通螺旋插裝式比例閥可以對工作裝置實現單獨控制。
