派克取力器圖片489ZLDAX-A5XD華東總：PARKER比例閥具有應(yīng)用靈活、節(jié)省管路和成本低廉等特點(diǎn)，近年來(lái)工程機(jī)械上應(yīng)用越來(lái)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(jié)流閥，它常它元件一起構(gòu)成復(fù)合閥，對(duì)流量、壓力進(jìn)行控制；三通式比例閥主比例減壓閥，也是移動(dòng)式機(jī)械液壓系統(tǒng)中應(yīng)用較多比例閥，它主對(duì)液動(dòng)操作多路閥先導(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)手動(dòng)減壓式先導(dǎo)閥，它比手動(dòng)先導(dǎo)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(dòng)多路閥，不同輸入信號(hào)，減壓閥使輸出活塞具有不同壓力或流量進(jìn)而實(shí)現(xiàn)對(duì)多路閥閥芯位移進(jìn)行比例控制。四通或多通螺旋插裝式比例閥可以對(duì)工作裝置實(shí)現(xiàn)單獨(dú)控制。 滑閥式比例閥又稱分配閥，是移動(dòng)式機(jī)械液壓系統(tǒng)zui基本元件之一，是能實(shí)現(xiàn)方向與流量調(diào)節(jié)復(fù)合閥。電液滑閥式比例多路閥是比較理想電液轉(zhuǎn)換控制元件，它保留了手動(dòng)多路閥基本功能，還增加了位置電反饋比例伺服操作和負(fù)載傳感等*控制手段。它是工程機(jī)械分配閥更新?lián)Q代產(chǎn)品。
