液壓系統充液閥分類及其産品特性
充液閥分類:
充液閥從是否可控制上來分,可分爲:可控式充液閥(相當于液控單向閥)和不可控充液閥(相當于普通單向閥),實際上用的較多的是可控式充液閥。可控式充液閥又可分爲:不帶卸荷裝置的普通型充液閥和帶卸荷裝置的先導型充液閥。裝有普通型充液閥的液壓系統在設計時必須考慮增加單獨的卸壓裝置,而先導型充液閥在理論上可以不單獨增設卸壓裝置,但在實際應用中發現,其卸壓效果并不理想,因此往往在系統衆增設獨立的卸壓裝置來減小液壓沖擊。
充液閥從閥口的工作狀態上來分,可分爲:常開式(即正常狀態時,閥口打開,充液閥處于開啓狀態)和常閉式(正常狀態下,閥口關閉,充液閥處于關閉狀態)。常開式優點在于吸油充液過程中不需要克服彈簧力,減小吸油阻力,但結構複雜,制造要求也較高,一般情況下很少采用。
充液閥産品特性:
1、充液閥一般作爲液壓缸和油箱間的吸排油閥使用,大型壓力機的快進行程,要從油缸向油箱吸油,加壓時防止從油缸流入油箱,反向時從油缸排油到油箱。
2、法蘭型充液閥體積小,通過流量大且無洩漏,可直接焊接或用法蘭固定。
3、充液材質分別有合金鋼和鑄鐵。
4、充液閥常用于大型壓機和注塑機中用于當油箱向缸補油,從而可在使用小泵條件下實現快速運動。在缸快進時,從油箱向缸大量充液,在加壓過程,可切斷缸到油箱的回流,當缸返回時,先導控制壓力油迫使充液閥打開,使缸內油排回油箱。
