先導式減壓閥結(jié)構(gòu)與工作原理
一般在液壓系統(tǒng) 中,往往一個液壓油泵需要同時向幾個執(zhí)行元件供油,而各執(zhí)行元件所需的工作壓力不盡相同。著某個執(zhí)行元件所需的工作壓力較液壓泵的供油壓力(即系統(tǒng)壓力)低時,可在該分支油路中串聯(lián)一減壓閥,所需壓力大小可用減壓閥來調(diào)節(jié)。
減壓閥是一種利用液流流過隙縫産生壓降的原理,使出口壓力低于進口壓力的壓力控制閥。根據(jù)調(diào)節(jié)性能的不同,減壓閥又可分爲定值減壓閥、定比減壓閥和定差減壓閥三種。其中定值減壓閥應(yīng)用廣,它可以保持出口壓力爲定值,使液壓系統(tǒng)中某一支路的壓力低于系統(tǒng)壓力且保持壓力穩(wěn)定。
減壓閥也分直動式和先導式兩種,直動式減壓閥在系統(tǒng)中較少單獨使用,先導式減壓閥則應(yīng)用較多,直動式減壓閥與先導式減壓閥特點的比較可以參考下表:
下圖爲先導式減壓閥的結(jié)構(gòu)。它由先導閥和主閥兩部分組成。先導閥閥芯5在調(diào)壓彈簧4的作用下,緊壓在先導閥閥座6上,調(diào)節(jié)螺母1可改變彈簧4對先導閥作用的預(yù)緊其作用是克服摩擦力、將主閥芯壓向最左端。減壓閥的作用有兩個:一是將較高的入口壓力(通常稱爲一次壓力)p1減低爲較低的出口壓力(通常稱爲二次壓力)p2;二是保持p2的穩(wěn)定。簡單地說,就是減壓和穩(wěn)壓的作用。
