DBDH10P1X/200 REXROTH溢流閥,德國力士樂REXROTH進(jìn)口品牌備件,德國產(chǎn)地,質(zhì)量保障,現(xiàn)貨庫存,價(jià)格優(yōu)勢供應(yīng);
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(hù)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)壓力增大時(shí),會(huì)使流量需求減小。此時(shí)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(dòng)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(yùn)動(dòng)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(shí),溢流閥的遙控口通油箱,此時(shí)液壓泵卸荷。溢流閥此時(shí)作為卸荷閥使用。
安全保護(hù)作用:系統(tǒng)正常工作時(shí),閥門關(guān)閉。只有負(fù)載超過規(guī)定的極限(系統(tǒng)壓力超過調(diào)定壓力)時(shí)開啟溢流,進(jìn)行過載保護(hù),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)最高工作壓力高10%~20%)。
實(shí)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)。

淺析先導(dǎo)式溢流閥與直動(dòng)型溢流閥的區(qū)別
溢流閥可分為直動(dòng)型和先導(dǎo)式兩類。直動(dòng)型溢流閥是作用在閥芯上的主油路液壓力與調(diào)壓彈簧力直接相平衡的溢流閥。根據(jù)閥口和測壓面結(jié)構(gòu)形式不同,形成三種基本結(jié)構(gòu)。
先導(dǎo)式溢流閥:主閥彈簧主要用于克服閥芯的摩擦力,彈簧剛度小。當(dāng)溢流量變化引起主閥彈簧壓縮量變化時(shí),彈簧力變化較小,因此閥進(jìn)口壓力變化也較小。調(diào)壓精度高,廣泛應(yīng)用于高壓、大流量系統(tǒng)。
溢流閥的閥芯在移動(dòng)過程中要受到摩擦力的作用,閥口開大和關(guān)小時(shí)的摩擦力方向剛好相反,使溢流閥開啟時(shí)的特性與關(guān)閉時(shí)的特性產(chǎn)生差異。

DBDH10P1X/200 REXROTH溢流閥
安全閥在系統(tǒng)中起安全保護(hù)作用。當(dāng)系統(tǒng)壓力超過規(guī)定值時(shí),安全閥打開,將系統(tǒng)中的一部分氣體/流體排入大氣/管道外,使系統(tǒng)壓力不超過允許值,從而保證系統(tǒng)不因壓力過高而發(fā)生事故。
安全閥結(jié)構(gòu)主要有兩大類:彈簧式和杠桿式。彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。杠桿式是靠杠桿和重錘的作用力。隨著大容量的需要,又有一種脈沖式安全閥,也稱為先導(dǎo)式安全閥,由主安全閥和輔助閥組成。當(dāng)管道內(nèi)介質(zhì)壓力超過規(guī)定壓力值時(shí),輔助閥先開啟,介質(zhì)沿著導(dǎo)管進(jìn)入主安全閥,并將主安全閥打開,使增高的介質(zhì)壓力降低。
按結(jié)構(gòu)分
按其整體結(jié)構(gòu)及加載機(jī)構(gòu)的不同可以分為重錘杠桿式、彈簧式和脈沖式三種。
1.重錘杠桿式安全閥
重錘杠桿式安全閥是利用重錘和杠桿來平衡作用在閥瓣上的力。根據(jù)杠桿原理,它可以使用質(zhì)量較小的重錘通過杠桿的增大作用獲得較大的作用力,并通過移動(dòng)重錘的位置(或變換重錘的質(zhì)量)來調(diào)整安全閥的開啟壓力。
重錘杠桿式安全閥結(jié)構(gòu)簡單,調(diào)整容易而又比較準(zhǔn)確,所加的載荷不會(huì)因閥瓣的升高而有較大的增加,適用于溫度較高的場合,過去用得比較普遍,特別是用在鍋爐和溫度較高的壓力容器上。但重錘杠桿式安全閥結(jié)構(gòu)比較笨重,加載機(jī)構(gòu)容易振動(dòng),并常因振動(dòng)而產(chǎn)生泄漏;其回座壓力較低,開啟后不易關(guān)閉及保持嚴(yán)密。
2.彈簧微啟式安全閥
彈簧微啟式安全閥是利用壓縮彈簧的力來平衡作用在閥瓣上的力。螺旋圈形彈簧的壓縮量可以通過轉(zhuǎn)動(dòng)它上面的調(diào)整螺母來調(diào)節(jié),利用這種結(jié)構(gòu)就可以根據(jù)需要校正安全閥的開啟(整定)壓力。彈簧微啟式安全閥結(jié)構(gòu)輕便緊湊,靈敏度也比較高,安裝位置不受限制,而且因?yàn)閷φ駝?dòng)的敏感性小,所以可用于移動(dòng)式的壓力容器上。這種安全閥的缺點(diǎn)是所加的載荷會(huì)隨著閥的開啟而發(fā)生變化,即隨著閥瓣的升高,彈簧的壓縮量增大,作用在閥瓣上的力也跟著增加。這對安全閥的迅速開啟是不利的。另外,閥上的彈簧會(huì)由于長期受高溫的影響而使彈力減小。用于溫度較高的容器上時(shí),常常要考慮彈簧的隔熱或散熱問題,從而使結(jié)構(gòu)變得復(fù)雜起來。
3.脈沖式安全閥
脈沖式安全閥由主閥和輔閥構(gòu)成,通過輔閥的脈沖作用帶動(dòng)主閥動(dòng)作、其結(jié)構(gòu)復(fù)雜,通常只適用于安全泄放量很大的鍋爐和壓力容器。

按介質(zhì)分
按照介質(zhì)排放方式的不同, 安全閥又可以分為全封閉式、半封閉式和開放式等三種。
1.全封閉安全閥
全封閉式安全閥排氣時(shí),氣體全部通過排氣管排放,介質(zhì)不能間外泄漏,主要用于介質(zhì)為有毒。易燃?xì)怏w的容器。
2.半封閉式安全閥
半封閉式安全閥所排出的氣體一部分通過排氣管,也有一部分從閥蓋與閥桿間的間隙中漏出,多用于介質(zhì)為不會(huì)污染環(huán)境的氣體的容器。
3.開放式安全閥
開放式安全閥的閥蓋是敞開的,使彈簧腔室與大氣相通,這樣有利于降低彈簧的溫度,主要適用于介質(zhì)為蒸汽,以及對大氣不產(chǎn)生污染的高溫氣體的容器。
按閥瓣開啟分
按照閥瓣開啟的最大高度與安全閥流道直徑之比來劃分,安全閥又可分為彈簧微啟封閉高壓式安全閥和彈簧全啟式安全閥兩種。
1.彈簧微啟封閉式高壓安全閥
微啟式安全閥的開啟高度小于流道直徑的1/4,通常為流道直徑的1/40一1/20。微啟式安全閥的動(dòng)作過程是比例作用式的,主要用于液體場合,有時(shí)也用于排放量很小的氣體場合。
2.彈簧全啟式安全閥
全啟式安全閥的開啟高度大于或等于流道直徑的1/4。全啟式安全閥的排放面積是閥座喉部最小截面積。其動(dòng)作過程是屬于兩段作用式,必須借助于一個(gè)升力機(jī)構(gòu)才能達(dá)到全開啟,全啟式安全閥主要用于氣體介質(zhì)的場合。
3.中啟式安全閥
開啟高度介于微啟式與全啟式之間。即可以做成兩段作用,也可以做成比例作用式。
