力士樂REXROTH液控單向閥應用
(1)保持壓力。
滑閥式換向閥都有間隙泄漏現象,只能短時間保壓。當有保壓要求時,可在油路上加一個液控單向閥,利用錐閥關閉的嚴密性,使油路長時間保壓。
(2)液壓缸的“支承”。
在立式液壓缸中,由于滑閥和管的泄漏,在活塞和活塞桿的重力下,可能引起活塞和活塞桿下滑。將液控單向閥接于液壓缸下腔的油路,則可防止液壓缸活塞和滑塊等活動部分下滑。
(3)實現液壓缸鎖緊。
當換向閥處于中位時,兩個液控單向閥關閉,可嚴密封閉液壓缸兩腔的油液,這時活塞就不能因外力作用而產生移動。
(4)大流量排油。
液壓缸兩腔的有效工作面積相差很大。在活塞退回時,液壓缸右腔排油量驟然增大,此時若采用小流量的滑閥,會產生節流作用,限制活塞的后退速度;若加設液控單向閥,在液壓缸活塞后退時,控制壓力油將液控單向閥打開,便可以順利地將右腔油液排出。
(5)作充油閥。
立式液壓缸的活塞在高速下降過程中,因高壓油和自重的作用,致使下降迅速,產生吸空和負壓,必須增設補油裝置。液控單向閥作為充油閥使用,以完成補油功能。
(6)組合成換向閥。
