液壓系統(tǒng)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(wèi):可控式充液閥(相當(dāng)于液控單向閥)和不可控充液閥(相當(dāng)于普通單向閥),實(shí)際上用的較多的是可控式充液閥。可控式充液閥又可分爲(wèi):不帶卸荷裝置的普通型充液閥和帶卸荷裝置的先導(dǎo)型充液閥。裝有普通型充液閥的液壓系統(tǒng)在設(shè)計(jì)時(shí)必須考慮增加單獨(dú)的卸壓裝置,而先導(dǎo)型充液閥在理論上可以不單獨(dú)增設(shè)卸壓裝置,但在實(shí)際應(yīng)用中發(fā)現(xiàn),其卸壓效果并不理想,因此往往在系統(tǒng)衆(zhòng)增設(shè)獨(dú)立的卸壓裝置來減小液壓沖擊。
充液閥從閥口的工作狀態(tài)上來分,可分爲(wèi):常開式(即正常狀態(tài)時(shí),閥口打開,充液閥處于開啓狀態(tài))和常閉式(正常狀態(tài)下,閥口關(guān)閉,充液閥處于關(guān)閉狀態(tài))。常開式優(yōu)點(diǎn)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(jié)構(gòu)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(wèi)液壓缸和油箱間的吸排油閥使用,大型壓力機(jī)的快進(jìn)行程,要從油缸向油箱吸油,加壓時(shí)防止從油缸流入油箱,反向時(shí)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(zhì)分別有合金鋼和鑄鐵。
4、充液閥常用于大型壓機(jī)和注塑機(jī)中用于當(dāng)油箱向缸補(bǔ)油,從而可在使用小泵條件下實(shí)現(xiàn)快速運(yùn)動(dòng)。在缸快進(jìn)時(shí),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(dāng)缸返回時(shí),先導(dǎo)控制壓力油迫使充液閥打開,使缸內(nèi)油排回油箱。
