單向閥又稱止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動(dòng),或者用于氣動(dòng)系統(tǒng)中防止壓縮空氣逆向流動(dòng)。
單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。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。                                                       R900523244 SL6PB2-6X/V
