ZDB10VA2-4X/200V力士樂溢流閥
DBD 類型的溢流閥是直接操作式座閥。
它們用于限制系統(tǒng)壓力。
這些閥門的基本組成部件為:套筒(1),彈簧(2),帶阻尼
活塞的提升閥(3)(壓力等級 25 到 400 bar)或滾珠(4)
(壓力等級 630 bar)以及調(diào)節(jié)元件(5)。系統(tǒng)壓力可由調(diào)節(jié)
元件(5)不斷地改變。彈簧(2)將提升閥(3)或滾珠(4)
按壓到其座上。通道 P 與系統(tǒng)連接。系統(tǒng)中的主要壓力作用于
提升閥區(qū)域(或滾珠)。
如果通道 P 中的壓力上升并超過彈簧(2)上設(shè)定的值,則提
升閥(3)或滾珠(4)背向彈簧(2)打開。液壓油現(xiàn)在可以
從通道 P 流入通道 T。提升閥(3)的位移受到凸起(6)的
限制。
為了在整個壓力范圍上得到良好壓力設(shè)置,將整個壓力范圍再
分為了 7 個壓力等級。一個壓力等級對應(yīng)一個特定的彈簧,該
彈簧可用于設(shè)置較大工作壓力。

溢流閥是一種液壓壓力控制閥。在液壓設(shè)備中主要起定壓溢流作用,穩(wěn)壓,系統(tǒng)卸荷和安全保護作用。 定壓溢流作用:在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中,定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力加大時,會使流量需求減小。此時溢流閥開啟,使多余流量溢回油箱,保證溢流閥進口壓力,即泵出口壓力恒定(閥口常隨壓力波動開啟)。
穩(wěn)壓作用:溢流閥串聯(lián)在回油路上,溢流閥產(chǎn)生背壓運動部件平穩(wěn)性增加。
系統(tǒng)卸荷作用:在溢流閥的遙控口串接溢小流量的電磁閥,當(dāng)電磁鐵通電時,溢流閥的遙控口通油箱,此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。
安全保護作用:系統(tǒng)正常工作時,閥門關(guān)閉。只有負載超過規(guī)定的較限(系統(tǒng)壓力超過調(diào)定壓力)時開啟溢流,進行過載保護,使系統(tǒng)壓力不再增加(通常使溢流閥的調(diào)定壓力比系統(tǒng)較高工作壓力高10%~20%)。

先導(dǎo)式溢流閥有一個遠程控制口K,如果將K口用油管接到另一個遠程調(diào)壓閥(遠程調(diào)壓閥的結(jié)構(gòu)和溢流閥的先導(dǎo)控制部分一樣),調(diào)節(jié)遠程調(diào)壓閥的彈簧力,即可調(diào)節(jié)溢流閥主閥芯上端的液壓力,從而對溢流閥的溢流壓力實現(xiàn)遠程調(diào)壓。但是,遠程調(diào)壓閥所能調(diào)節(jié)的較高壓力不得超過溢流閥本身導(dǎo)閥的調(diào)整壓力。當(dāng)遠程控制口K通過二位二通閥接通油箱時,主閥芯上端的壓力接近于零,主閥芯上移到較高位置.閥口開得很大。由于主閥彈簧較軟,這時溢流閥p口處壓力很低,系統(tǒng)的油在低壓下通過溢流閥流回油箱,實現(xiàn)卸荷。

方向控制閥
類型:單向閥、換向閥
一、單向閥
類型:普通單向閥、液控單向閥
1、普通單向閥
作用:只允許油液沿一個方向流動,不允許油液反向倒流(起止回作用)
對單向閥的性能要求:
(1) 正向?qū)〞r,壓力損失要小;
(2)反向截止時,密封性要好。
2、
液控單向閥
作用:
(1)起止回作用;
(2)必要時解除逆止,允許油液反向通過。
3、單向閥用途
(1)止回作用:安裝在泵的出口,p.=0.3~0.5 bar
(2)作背壓閥用:防止液壓缸前沖或爬行,使系統(tǒng)作平穩(wěn)。
(3)作鎖緊裝置用:起重機支腿、夾緊回路等。
(4)保持控制油路有必要的壓力: Pr≥P液挖
(5)作復(fù)合閥使用:單向節(jié)流閥、單向順序閥、單向減壓閥、單向調(diào)速閥等。
(6)局部回路作安全閥使用: Ppr>P換熱器正常工作的距力
