SV10PA1-4X/力士樂液控單向閥
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。但在液壓回路中需要油流反向流動時又可利用控制油壓，打開單向閥，使油流在兩個方向都可流動。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，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泄式和外泄式二種。在油流反向出口無背壓的油路中可用內泄式；否則需用外泄式，以降低控制油壓力。

（1）結構原理
1）MK型單向節流閥 圖27是MK型單向節流閥的結構原理圖。該閥是管式聯接的單向節流閥，其節流口采用軸向三角槽式結構。旋轉調節螺母3，可改變節流口通流面積的大小，以調節流量。正向流動時起節流閥作用；反向流動時起單向閥作用，這時由于有部分油液可在環形縫隙中流動，可以清除節流口上的沉積物。在閥體2左端有刻度槽，調節螺母3上有刻度，用以標志調節流量的大小。
2）F型精密節流閥 圖28是F型精密節流閥的結構原理圖。該閥主要由閥體1，調節件2和節流套3組成。在節流口4處實現對從A到B的流動的節流。轉動節流桿5，可調節節流斷面。由于節流口制成薄壁孔，故節流不易受溫度的影響。
