DBDS6P1X/100力士樂安全閥，德國力士樂REXROTH全新原裝進口品牌備件，德國產(chǎn)地，質(zhì)量保障，現(xiàn)貨價格優(yōu)勢供應(yīng)；

按結(jié)構(gòu)分
按其整體結(jié)構(gòu)及加載機構(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)整容易而又比較準確，所加的載荷不會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，加載機構(gòu)容易振動，并常因振動而產(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，而且因為對振動的敏感性小，所以可用于移動式的壓力容器上。這種安全閥的缺點是所加的載荷會隨著閥的開啟而發(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，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主閥動作、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。

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。當系統(tǒng)壓力增大時，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。只有負載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啟溢流，進行過載保護，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)最高工作壓力高10%～20%）。
實際應(yīng)用中一般有：作卸荷閥用，作遠程調(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)式溢流閥。
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。
先導(dǎo)型溢流閥的導(dǎo)閥部分結(jié)構(gòu)尺寸較小，調(diào)壓彈簧不必很強，因此壓力調(diào)整比較輕便。但因先導(dǎo)型溢流閥要在先導(dǎo)閥和主閥都動作后才能起控制作用，因此反應(yīng)不如直動型溢流閥靈敏。
與三節(jié)同心結(jié)構(gòu)相比，二節(jié)同心結(jié)構(gòu)的特點是：①主閥芯僅與閥套和主閥座有同心度要求，免去了與閥蓋的配合，故結(jié)構(gòu)簡單，加工和裝配方便。②過流面積大，在相同流量的情況下，主閥開啟高度小；或者在相同開啟高度的情況下，其通流能力大，因此，可做得體積小、重量輕。③主閥芯與閥套可以通用化，便于組織批量生產(chǎn)。

先導(dǎo)溢流閥的主閥上腔壓力，是由先導(dǎo)閥加于控制的。如果先導(dǎo)閥正常工作，即主閥上腔有先導(dǎo)閥規(guī)定的壓力，則整個溢流閥就會在系統(tǒng)壓力到達調(diào)定壓力時其主閥口打開一定的開度，一方面能將系統(tǒng)多余流量流回油箱，另一方面又能維持系統(tǒng)的壓力為先導(dǎo)閥的調(diào)定值。可見，先導(dǎo)閥主要管壓力，主閥服從先導(dǎo)閥的領(lǐng)導(dǎo)，在先導(dǎo)閥動作時將主閥口開到合適大小，正好將多余流量流出去，又不影響系統(tǒng)壓力。

淺析先導(dǎo)式溢流閥與直動型溢流閥的區(qū)別
溢流閥可分為直動型和先導(dǎo)式兩類。直動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。當溢流量變化引起主閥彈簧壓縮量變化時，彈簧力變化較小，因此閥進口壓力變化也較小。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過程中要受到摩擦力的作用，閥口開大和關(guān)小時的摩擦力方向剛好相反，使溢流閥開啟時的特性與關(guān)閉時的特性產(chǎn)生差異。
