ZDB6VP2-4X/50V溢流閥使用要求

先導(dǎo)型溢流閥的特點(diǎn)

先導(dǎo)閥和主閥閥芯分別處于受力平衡，其閥口都滿足壓力流量方程。閥的進(jìn)口壓力由兩次比較得到，壓力值主要由先導(dǎo)閥調(diào)壓彈簧的預(yù)壓縮量確定，主閥彈簀起復(fù)位作用。

通過(guò)先導(dǎo)閥的流量很小，是主閥額定流量的1%因此其尺寸很小，即使是高壓閥，其彈簧剛度也不大。這樣一來(lái)閥的調(diào)節(jié)性能有很大改善。

主閥芯開(kāi)啟是利用液流流經(jīng)阻力孔形成的壓力差。阻力孔一般為細(xì)長(zhǎng)孔，孔徑很小0=0.8~1.2mm,孔長(zhǎng)I = 8~12mm,因此工作時(shí)易堵塞，一旦堵塞則導(dǎo)致主閥口常開(kāi)無(wú)法調(diào)壓。

溢流閥的功用

溢流閥旁接在泵的出口，用來(lái)保證系統(tǒng)壓力恒定，稱為定壓閥。

溢流閥旁接在泵的出口，用來(lái)限制系統(tǒng)壓力的較大值，對(duì)系統(tǒng)起保護(hù)作用，稱為安全閥。

電磁溢流閥還可以在執(zhí)行機(jī)構(gòu)不工作時(shí)使泵卸載。

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，穩(wěn)壓，系統(tǒng)卸荷和安全保護(hù)作用。溢流閥在裝配或使用中，由于O形密封圈、組合密封圈的損壞，或者安裝螺釘、管接頭的松動(dòng)，都可能造成不應(yīng)有的外泄漏。如果錐閥或主閥芯磨損過(guò)大，或者密封面接觸不良，還將造成內(nèi)泄漏過(guò)大，甚至影響正常工作。

DB 型溢流閥當(dāng)由于各種原因， 空氣被吸入油液中， 或者在油液壓力低于大氣壓時(shí)， 溶解在油液中的部分空氣就會(huì)析出形成氣泡， 這些氣泡在低壓區(qū)時(shí)體積較大， 當(dāng)隨油液流到高壓區(qū)時(shí)， 受到壓縮， 體積突然變小或氣泡消失 而當(dāng)流到低壓區(qū)時(shí)， 體積突然加大， 油中氣泡體積這種急速改變的現(xiàn)象。 氣泡體積的突然改變會(huì)產(chǎn)生噪聲， 又由于這一過(guò)程發(fā)生在瞬間， 將引起局部液壓沖擊而產(chǎn)生振動(dòng)。 先導(dǎo)型溢流閥的導(dǎo)閥口和主閥口， 油液流速和壓力的變�；�很大， 很容易出現(xiàn)空穴現(xiàn)象， 由此而產(chǎn)生噪聲和振動(dòng)。

ZDB6VP2-4X/50V溢流閥使用要求

ZDB 和 Z2DB 型壓力閥是一種采用疊加閥板設(shè)計(jì)的先導(dǎo)式溢流閥。

這些閥用于限制系統(tǒng)壓力。

這些閥門(mén)主要由殼體 (7) 和一個(gè)或兩個(gè)壓力閥閥芯組成。

可通過(guò)調(diào)整類型 (4) 設(shè)置系統(tǒng)壓力。

示例型號(hào)“VA”：

在初始位置時(shí)閥關(guān)閉。通道 A 中的壓力作用于閥芯 (1)。同時(shí)，壓力還通過(guò)噴嘴 (2) 施加于閥芯 (1) 的彈簧負(fù)載側(cè)并通過(guò)噴嘴 (3) 施加于先導(dǎo)座 (6)。如果通道 A 中的壓力超過(guò)彈簧 (5) 上設(shè)定的值，則先導(dǎo)座 (6) 開(kāi)啟。

液壓油從閥芯 (1) 的彈簧負(fù)載側(cè)、噴嘴 (3) 和通道 (8) 流入通道 T。所產(chǎn)生的壓降使閥芯 (1) 移動(dòng)，從而打開(kāi)從 A 到 T 的連接，同時(shí)維持彈簧 (5) 處設(shè)定的壓力。

兩個(gè)彈簧腔的先導(dǎo)泄油通過(guò)通道 T 于外部實(shí)現(xiàn)。

減壓：

在控制腔 (16) 中建立先導(dǎo)壓力，作為控制值的功能。

主控制閥芯 (4) 向右移動(dòng)，液壓油從 P 流向 P1。

施加于油口 P1 中的執(zhí)行機(jī)構(gòu)壓力通過(guò)通道 (13) 和噴嘴 (14) 對(duì)彈簧腔 (15) 分流。

如果油口 P1 中的壓力升高到先導(dǎo)控制閥 (1) 的調(diào)定壓力，則主控制閥芯 (4) 向左移動(dòng)。油口 P1 中的壓力與先導(dǎo)控制閥 (1) 處的調(diào)定壓力幾乎完全相同。

壓力限制：

如果油口 P1 中的壓力超過(guò)先導(dǎo)控制閥 (1) 的調(diào)定壓力，主控制閥芯 (4) 將進(jìn)一步向左移動(dòng)。

這樣即可開(kāi)啟從 P1 到 T 的連接，進(jìn)而將油口 P1 中的壓力限制到調(diào)定控制值。

力士樂(lè)REXROTH先導(dǎo)式溢流閥ZDB 10, Z2DB 10

蝶閥(英文：butterfly valve)是指關(guān)閉件(閥瓣或蝶板)為圓盤(pán)，圍繞閥軸旋轉(zhuǎn)來(lái)達(dá)到開(kāi)啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個(gè)圓盤(pán)形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥全開(kāi)到全關(guān)通常是小于90° ，蝶閥和蝶桿本身沒(méi)有自鎖能力，為了蝶板的定位，要在閥桿上加裝蝸輪減速器。采用蝸輪減速器，不僅可以使蝶板具有自鎖能力，使蝶板停止在任意位置上，還能改善閥門(mén)的操作性能。工業(yè)專項(xiàng)使用蝶閥的特點(diǎn)：能耐高溫，適用壓力范圍也較高，閥門(mén)公稱通徑大，閥體采用碳鋼制造，閥板的密封圈采用金屬環(huán)代替橡膠環(huán)。
