武穴黎翔機電設(shè)備有限公司REXROTH力士樂銷售部

廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機械、食

比例閥采用閥芯+閥體結(jié)構(gòu)。伺服閥和伺服比例閥主要應(yīng)用在閉環(huán)控制系統(tǒng)，比例閥的驅(qū)動裝置是比例電磁鐵。
伺服閥的驅(qū)動裝置是力馬達(dá)或力矩馬達(dá).閥體兼作閥套。
驅(qū)動裝置不同.所以近些年出現(xiàn)了比例伺服閥。
比例閥一般較高幾十Hz，伺服閥中位沒有死區(qū)，伺服閥對液壓油液的要求更高.性能參數(shù)不同；否則容易堵塞，
用來控制流量和流向，比例閥要求低一些.比例閥有中位死區(qū)；
比例閥和伺服閥的區(qū)別主要體現(xiàn)在以下幾點：
逐漸向伺服閥靠近，
比例換向閥屬于比例閥的一種，滯環(huán)、中位死區(qū)、頻寬、過濾精度等特性不同.閥的額定壓降不同；比例換向閥具有與普通換向閥相似的中位機能，
而比例伺服閥性能介于伺服閥和比例閥之間，因此應(yīng)用場合不同，伺服閥和伺服比例閥采用閥芯+閥套的結(jié)構(gòu)。中位機能種類不同.其它結(jié)構(gòu)的比例閥主要應(yīng)用在開環(huán)控系統(tǒng)及閉環(huán)速度控制系統(tǒng)；因為比例閥的性能越來越好；2伺服閥的頻響（響應(yīng)頻率）更高。閥芯結(jié)構(gòu)及加工精度不同.伺服閥與比例閥之間的差別并沒有嚴(yán)格的規(guī)定。
，可以高達(dá)200Hz左右，需要精過濾才行，而伺服閥中位機能只有O型（Rexroth產(chǎn)品的E型）。

 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(jìn)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(fù)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(jìn)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%）。 　　
實際應(yīng)用中一般有：作卸荷閥用，作遠(yuǎn)程調(diào)壓閥，作高低壓多級控制閥，作順序閥，用于產(chǎn)生背壓（串在回油路上）。 　　
溢流閥一般有兩種結(jié)構(gòu)：1、直動型溢流閥 。2、先導(dǎo)型溢流閥。 　　
對溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。DBW20B2-5X/3506EG24N9K4
