德國REXROTH力士樂比例閥工作原理,力士樂比例閥技術參數,德國REXROTH力士樂比例閥力士樂Rexroth電磁閥
德國rexroth比例閥VT-NE30-2X比例閥是螺紋將電磁比例插裝件固定油路集成塊上元件,德國REXROTH力士樂比例閥螺旋插裝閥具有應用靈活、德國REXROTH力士樂比例閥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。
REXROTH力士樂比例閥一般采用兩端承壓面積不等的差徑活塞結構。比例閥不工作時,差徑活塞2在彈簧3的作用下處于上極限位置,此時閥門1保持開啟,因而在輸入控制壓力P1與輸出壓力P2從零同步增長的初始階段,總是P1等于P2。但是壓力P1的作用面積A1為π(D2-d2)/4,壓力P2的作用面積A2為πD2/4,因而A2大于A1,故活塞上方液壓作用力大于活塞下方液壓作用力。在P1、P2同步增長過程中,當活塞上、下兩端液壓作用之差超過彈簧3的預緊力時,活塞便開始下移。當P1和P2增長到一定值PS時活塞2內腔中的閥座與閥門1接觸,進油腔與出油腔即為隔絕,使比例閥進入平衡狀態。若進一步提高P1則活塞將回升,閥門再度開啟,油液繼續流入出油腔而使P2不斷升高,但由于A2大于A1,P2尚未增長到新的P1值,活塞又下降到平衡位置。在任一平衡狀態下,差徑活塞的力的平衡方程為:P2路A2=P1路A1+F(此處F為平衡狀態下的彈簧力)。
從而保證P2的增量小于P1的增量,若彈簧3的彈力F不變,則PS點不變,即比例閥節制后輪管路壓力的工作點與汽車的載荷無關,這就是非感比例閥。若要使其工作點與汽車載荷的大小相適應,就必須能改變彈簧力的大小,這就是感載比例閥。閥體安裝在車架上,其中的活塞4右部的空腔內有閥門2。不制動時,活塞在感載拉力彈簧6通過杠桿5施加的推力F作用下處于右端極限位置,閥門2因其桿部頂觸螺塞1而開啟。
