SV10PA1-4X/力士樂(lè)液控單向閥
單向閥 Check Valve?
單向閥又稱止回閥或逆止閥。液控單向閥也稱閉鎖閥或保壓閥，它與單向閥相同，用以防止油液反向流動(dòng)。但在液壓回路中需要油流反向流動(dòng)時(shí)又可利用控制油壓，打開(kāi)單向閥，使油流在兩個(gè)方向都可流動(dòng)。液控單向閥采用錐形閥芯，因此密封性能好。在要求封閉油路時(shí)，可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無(wú)背壓的油路中可用內(nèi)泄式；否則需用外泄式，以降低控制油壓力。

（1）結(jié)構(gòu)原理
1）MK型單向節(jié)流閥 圖27是MK型單向節(jié)流閥的結(jié)構(gòu)原理圖。該閥是管式聯(lián)接的單向節(jié)流閥，其節(jié)流口采用軸向三角槽式結(jié)構(gòu)。旋轉(zhuǎn)調(diào)節(jié)螺母3，可改變節(jié)流口通流面積的大小，以調(diào)節(jié)流量。正向流動(dòng)時(shí)起節(jié)流閥作用；反向流動(dòng)時(shí)起單向閥作用，這時(shí)由于有部分油液可在環(huán)形縫隙中流動(dòng)，可以清除節(jié)流口上的沉積物。在閥體2左端有刻度槽，調(diào)節(jié)螺母3上有刻度，用以標(biāo)志調(diào)節(jié)流量的大小。
2）F型精密節(jié)流閥 圖28是F型精密節(jié)流閥的結(jié)構(gòu)原理圖。該閥主要由閥體1，調(diào)節(jié)件2和節(jié)流套3組成。在節(jié)流口4處實(shí)現(xiàn)對(duì)從A到B的流動(dòng)的節(jié)流。轉(zhuǎn)動(dòng)節(jié)流桿5，可調(diào)節(jié)節(jié)流斷面。由于節(jié)流口制成薄壁孔，故節(jié)流不易受溫度的影響。
