力士樂(lè)單向閥SL6PB1-64大量庫(kù)存 力士樂(lè)單向閥是流體只能沿進(jìn)水口流動(dòng),出水口介質(zhì)卻無(wú)法回流,俗稱(chēng)單向閥。單向閥又稱(chēng)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。

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(chēng)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。 R900590409SL6PB2-6X/
