派克比例閥D31FBA31CC4NKW0結(jié)構(gòu)原理:輸入信號增大,供氣用電磁閥先導(dǎo)閥1換向,而排氣用電磁先導(dǎo)閥7處于復(fù)位狀態(tài),則供氣壓力從SUP口通過閥1進入先導(dǎo)室5,先導(dǎo)室壓力上升,氣壓力作用在膜片2的上方,則和膜片2相連的供氣閥芯4便開啟,排氣閥芯3關(guān)閉,產(chǎn)生輸出壓力。此輸出壓力通過壓力傳感器6反饋至控制回路8。在這里,與目標(biāo)值進行快速比較修正,知道輸出壓力與輸入信號成一定比例為止,從而得到輸出壓力與輸入信號的變化成比例的變化。由于沒有噴嘴擋板機構(gòu),故閥對雜質(zhì)不敏感,可靠性高。
派克比例閥D31FBA31CC4NKW0特點:可實現(xiàn)壓力、速度的無極調(diào)節(jié),避免了常通的開關(guān)式氣閥換向時的沖擊現(xiàn)象。能實現(xiàn)遠程控制和程序控制。與斷續(xù)控制相比,系統(tǒng)簡化,元件大大減少。與液壓比例閥相比,體積小、重量輕、結(jié)構(gòu)簡單、成本較低,但響應(yīng)速度比液壓系統(tǒng)慢得多,對負載變化也比較敏感。使用功率小、發(fā)熱少、噪聲低。不會發(fā)生火災(zāi),*。受溫度變化的影響小。

派克比例閥先導(dǎo)式比例方向閥有4個尺寸:
D31FB NG10 (CETOP 5)
D41FB NG16 (CETOP 7)
D91FB NG25 (CETOP 8)
D111FB NG32 (CE*0)
派克比例閥或伺服閥的目的就是:以電控方式實現(xiàn)對流量的節(jié)流控制(當(dāng)然經(jīng)過結(jié)構(gòu)上的改動也可實現(xiàn)壓力控制等),既然是節(jié)流控制,就必然有能量損失,伺服閥和其它閥不同的是,它的能量損失更大一些,因為它需要一定的流量來維持前置級控制油路的工作。
