德國(guó)寶德(螺旋插裝式)burkert比例閥是通過螺紋將電磁比例插裝件固定在油路集成塊上的元件,螺旋插裝閥具有應(yīng)用靈活、節(jié)省管路和成本低廉等特點(diǎn),近年來在工程機(jī)械上的應(yīng)用越來越廣泛。常用的螺旋插裝式burkert比例閥有二通、三通、四通和多通等形式,二通式burkert比例閥主要是比例節(jié)流閥,它常與其它元件一起構(gòu)成復(fù)合閥,對(duì)流量、壓力進(jìn)行控制;三通式burkert比例閥主要是比例減壓閥,也是移動(dòng)式機(jī)械液壓系統(tǒng)中應(yīng)用較多的burkert比例閥,它主要是對(duì)液動(dòng)操作多路閥的先導(dǎo)油路進(jìn)行操作。利用三通式比例減壓閥可以代替?zhèn)鹘y(tǒng)的手動(dòng)減壓式先導(dǎo)閥,它比手動(dòng)的先導(dǎo)閥具有更多的靈活性和更高的控制精度煤泥烘干機(jī)。可以制成如圖1所示的比例伺服控制手動(dòng)多路閥,根據(jù)不同的輸入信號(hào),減壓閥使輸出活塞具有不同的壓力或流量進(jìn)而實(shí)現(xiàn)對(duì)多路閥閥芯的位移進(jìn)行比例控制。四通或多通的螺旋插裝式burkert比例閥可以對(duì)工作裝置實(shí)現(xiàn)單獨(dú)的控制振動(dòng)篩。
電液burkert比例閥是閥內(nèi)比例電磁鐵根據(jù)輸入的電壓信號(hào)產(chǎn)生相應(yīng)動(dòng)作,使工作閥閥芯產(chǎn)生位移,閥口尺寸發(fā)生改變并以此完成與輸入電壓成比例的壓力、流量輸出的元件。閥芯位移也可以以機(jī)械、液壓或電的形式進(jìn)行反饋礦山設(shè)備。由于電液burkert比例閥具有形式種類多樣、容易組成使用電氣及計(jì)算機(jī)控制的各種電液系統(tǒng)、控制精度高、安裝使用靈活以及抗污染能力強(qiáng)等多方面優(yōu)點(diǎn),因此應(yīng)用領(lǐng)域日益拓寬。近年研發(fā)生產(chǎn)的插裝式burkert比例閥和比例多路閥充分考慮到工程機(jī)械的使用特點(diǎn),具有先導(dǎo)控制、負(fù)載傳感和壓力補(bǔ)償?shù)裙δ芷扑闄C(jī)價(jià)格。它的出現(xiàn)對(duì)移動(dòng)式液壓機(jī)械整體技術(shù)水平的提升具有重要意義。特別是在電控先導(dǎo)操作、無(wú)線遙控和有線遙控操作等方面展現(xiàn)了其良好的應(yīng)用前景水泥廠設(shè)備。
