直動(dòng)式溢流閥

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

壓力流量特性:

溢流閥的進(jìn)口壓力隨流量變化而波動(dòng)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(shí)，流經(jīng)閥的流量為額定值時(shí)，溢流閥的進(jìn)口壓力。壓力損失略高于卸載壓力。

安全溢流閥有彈簧式和桿式兩大類。另外還有沖量式安全閥、先導(dǎo)式安全閥、安全切換閥、安全解壓閥、靜重式安全閥等。彈簧式安全閥主要依靠彈簧的作用力而工作，彈簧式安全閥中又有封閉和不封閉的，一般易燃、易爆或有毒的介質(zhì)應(yīng)選用封閉式，蒸汽或惰性氣體等可以選用不封閉式，在彈簧式安全閥中還有帶扳手和不帶扳手的。扳手的作用主要是檢查閥瓣的靈活程度，有時(shí)也可以用作手動(dòng)緊急泄壓用。杠桿式安全閥主要依靠杠桿重錘的作用力而工作，但由于杠桿式安全閥體積龐大往往限制了選用范圍。溫度較高時(shí)選用帶散熱器的安全閥。

溢流閥的性能指標(biāo)

�。�1）溢流閥靜態(tài)調(diào)壓偏差 閥的調(diào)定壓力與開啟壓力之差稱為靜態(tài)調(diào)壓偏差。溢流流量對(duì)系統(tǒng)壓力的影響一般在2~4kgf/cm2左右。調(diào)壓偏差越大，系統(tǒng)的壓力波動(dòng)也越大。

�。�2）溢流閥壓力振擺它是溢流閥在系統(tǒng)較大額定流量和較大壓力下工作時(shí)，所控制的壓力變動(dòng)。一般應(yīng)在±1~±3kgf/cm2左右。

�。�3）溢流閥卸載壓力當(dāng)系統(tǒng)的全部流量從溢流閥卸荷時(shí)，閥的壓力損失為卸載壓力，卸載壓力越小越好。

�。�4）溢流閥動(dòng)態(tài)指標(biāo)溢流閥調(diào)整好以后，從開始工作到穩(wěn)定工作一段的很短的過(guò)渡時(shí)間內(nèi)，被控制的油壓首先以衰減振蕩的形式圍繞所調(diào)定的工作壓力值上下波動(dòng)，然后才變?yōu)榉�(wěn)壓溢流狀態(tài)，當(dāng)工作機(jī)構(gòu)受沖擊載荷而系統(tǒng)壓力突然升高時(shí)，會(huì)出現(xiàn)壓力峰值。峰值壓力與調(diào)定壓力的差值稱為壓力超調(diào)量。超調(diào)量與調(diào)定壓力之比稱為超調(diào)值。超調(diào)值越小越好，高壓溢流閥超調(diào)值一般小于20%，中、低壓溢流閥一般小于50%，另外，它的振擺次數(shù)和過(guò)渡過(guò)程時(shí)間也愈小愈好。

溢流閥是壓力控制閥。其作用主要是控制系統(tǒng)壓力，以保護(hù)油泵和油路系統(tǒng)的安全及保持油路系統(tǒng)的壓力恒定。通經(jīng)為8毫米的溢流閥是一個(gè)小型的直接動(dòng)作的溢流閥，可以和主溢流閥的遙控口連接，對(duì)主溢流閥實(shí)現(xiàn)遠(yuǎn)程壓力調(diào)節(jié)。溢流閥的遙控口經(jīng)換向閥和油箱連接時(shí)，可使油路卸荷。此時(shí)溢流閥起卸荷作用。溢流閥的遙控口串聯(lián)換向閥和通經(jīng)為8毫米的溢流閥時(shí)，可實(shí)現(xiàn)壓力的多級(jí)控制。更換溢流閥的調(diào)節(jié)彈簧，可改變其壓力調(diào)節(jié)范圍。手輪順時(shí)針轉(zhuǎn)動(dòng)時(shí)，壓力升高。反之壓力降低。

先導(dǎo)式安全閥是依靠從導(dǎo)閥排出的介質(zhì)來(lái)驅(qū)動(dòng)或控制的。而導(dǎo)閥本身是一個(gè)直接作用式安全閥，有時(shí)也采用其他形式的閥門。先導(dǎo)式安全閥適用于高壓、大口徑的場(chǎng)合。先導(dǎo)式安全閥的主閥還可以設(shè)計(jì)成依靠工作介質(zhì)來(lái)密封的形式，或者可以對(duì)閥瓣施加比直接作用式安全閥大得多的機(jī)械載荷，因而具有良好的密封性能。同時(shí)，它的動(dòng)作很少受背壓的影響。這種安全閥的缺點(diǎn)在于它的可靠性同主閥和導(dǎo)閥有關(guān)，動(dòng)作不如直接作用式安全閥那樣迅速、可靠，而且結(jié)構(gòu)較復(fù)雜。
