F系列PARKER派克單向節(jié)流閥
派克單向節(jié)流閥的應(yīng)用
由于節(jié)流閥的流量不僅取決于節(jié)流口面積的大小,還與節(jié)流口前后的壓差有關(guān),閥的剛度小,故只適用于執(zhí)行元件負(fù)載變化很小且速度穩(wěn)定性要求不高的場(chǎng)合。
對(duì)于執(zhí)行元件負(fù)載變化大及對(duì)速度穩(wěn)定性要求高的節(jié)流調(diào)速系統(tǒng),必須對(duì)節(jié)流閥進(jìn)行壓力補(bǔ)償來(lái)保持節(jié)流閥前后壓差不變,從而達(dá)到流量穩(wěn)定
Parker派克F系列單向節(jié)流閥可以在規(guī)定的流動(dòng)方向上進(jìn)行流量調(diào)節(jié)。在反方向上油液克服很小的流動(dòng)阻力流過(guò)所裝的單向閥。兩級(jí)的針閥在調(diào)節(jié)旋鈕的前3圈可以對(duì)小流量進(jìn)行很精確的調(diào)節(jié)。后3圈閥全部被打開(kāi)。通過(guò)定位螺栓可以將閥的調(diào)節(jié)結(jié)果鎖定。
