直動式溢流閥

調(diào)壓范圍:在規(guī)定的范圍內(nèi)調(diào)節(jié)時，閥的輸出壓力能平穩(wěn)的升降，無突跳或遲滯現(xiàn)象。

壓力流量特性:

溢流閥的進口壓力隨流量變化而波動的性能;又稱為啟閉特性。

(p;-Pk)、(p;-Pp) 稱為調(diào)壓偏差，調(diào)壓偏差小好

nk=P/p。稱為開啟壓力比，

np=P/p。稱為閉合壓力比，nk、n,大好。

壓力損失和卸載壓力:當(dāng)調(diào)壓彈簧預(yù)壓縮量等于零或主閥上腔經(jīng)遙控口直接接回油箱時，流經(jīng)閥的流量為額定值時，溢流閥的進口壓力。壓力損失略高于卸載壓力。

溢流閥的功用

溢流閥旁接在泵的出口，用來保證系統(tǒng)壓力恒定，稱為定壓閥。

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

電磁溢流閥還可以在執(zhí)行機構(gòu)不工作時使泵卸載。

溢流閥遙控口接法

先導(dǎo)閥前腔有一遙控口，在該控制口接遠程調(diào)壓閥可實現(xiàn)遠控，接電磁閥通回油箱可實現(xiàn)卸載。

遠程調(diào)壓閥實際上是一個單獨的壓力先導(dǎo)閥，旁接在先導(dǎo)型溢流閥遙控口起遠程調(diào)壓作用，其調(diào)定壓力必須低于先導(dǎo)閥的調(diào)定壓力。無論哪個起作用，泵的溢流量始終經(jīng)主閥閥口回油箱。

力士樂溢流閥ZDB10VA1-4X/200V

ZDB和Z2DB型壓力閥是采用夾心板設(shè)計的先導(dǎo)式溢流閥。它們用于限制系統(tǒng)壓力。這些閥主要由殼體（7）和一個或兩個壓力閥芯組成。可以通過調(diào)節(jié)類型（4）設(shè)置系統(tǒng)壓力。

在初始位置，閥門關(guān)閉。通道A中的壓力作用在閥芯（1）上。同時，壓力通過噴嘴（2）施加到閥芯（1）的彈簧加載側(cè)，并通過噴嘴（3）施加到先導(dǎo)閥芯（6）。

如果通道A中的壓力超過在彈簧（5）上設(shè)定的值，則先導(dǎo)提升閥（6）打開。液壓油從閥芯（1），噴嘴（3）和通道（8）的彈簧加載側(cè)流入通道T（TA）。由此產(chǎn)生的壓降使閥芯（1）移動，并打開了從A到T（TA）的連接。在通道A中，設(shè)定在彈簧（5）上的壓力穩(wěn)定下來。

力士樂先導(dǎo)式溢流閥DB(C/T)

安全閥一般按結(jié)構(gòu)形式分為彈簧式安全閥和杠桿式安全閥、脈沖式安全閥，其中彈簧式安全閥應(yīng)用為普遍;按連接方式分為螺紋安全閥和法蘭安全閥。安全閥口徑一般都不大，常用的都在DN15mm-DN80mm之間，超過150mm一般都稱為大口徑安全閥
