力士樂電磁溢流閥 

 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（閥口常隨壓力波鑫開啟）,。 

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)鑫部件平穩(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)zui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(jí)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,、直鑫型溢流閥 ,。2、先導(dǎo)型溢流閥,。 　　

對(duì)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,，鑫作靈敏,，過載能力大，噪聲小,。

功能，截面,，符號(hào)

壓力閥類型 DBD.. K.. 是要安裝在油路塊中的直鑫式溢流閥,，

用于限制系統(tǒng)壓力?？墒褂谜{(diào)節(jié)元件（5）設(shè)置系統(tǒng)壓力,。

在初始位置時(shí)閥關(guān)閉。主油口 ① 中的壓力通過先導(dǎo)管路（1）

和閥心（2）作用于彈簧座（3）,。如果主油口 ① 中的壓力上

升并超過壓縮彈簧（4）上設(shè)定的值,，則閥心（2）開啟，工作

液流入主油口 ②,。

DBD..K 3

依照壓力設(shè)備導(dǎo)則 97/23/EC,，關(guān)于經(jīng)過類型測(cè)試的安全閥（類型 DBD..K../..E）的安全注意事項(xiàng)

– 在訂購經(jīng)過類型測(cè)試的安全閥之前,，請(qǐng)注意在所需的響應(yīng)壓

力 p 下，安全閥的zui大允許流量 qV zui大 大于要保護(hù)的系統(tǒng)/

蓄能器的zui大允許流量,。

請(qǐng)務(wù)必遵守相關(guān)規(guī)定,！

– 根據(jù) PED 97/23/EC，流量引起的系統(tǒng)壓力的升高不得超出

設(shè)定響應(yīng)壓力的 10%（請(qǐng)參見部件標(biāo)識(shí)）,。

不得超過在部件標(biāo)識(shí)中的zui大允許流量 qV zui大（等于在

部件標(biāo)識(shí)中的字母 "G" 處的數(shù)值,，請(qǐng)參閱上述內(nèi)容）。

安全閥的排泄管路必須在安全狀態(tài)下結(jié)束,。不允許在排泄系

統(tǒng)中存在液壓油堆積（請(qǐng)參閱 AD2000 - 數(shù)據(jù)表 A2）,。

必須遵守應(yīng)用說明！

– 部件標(biāo)識(shí)中的zui大允許流量適用于排泄管路

（油口 "T"）中無背壓的情況,。

– 如果卸下安全閥上的鉛封,，則依照 PED 的認(rèn)證將失效！

– 通常,，必須遵守壓力設(shè)備導(dǎo)則和數(shù)據(jù)表 AD2000 A2 的要求,！

– 建議鎖緊經(jīng)過類型測(cè)試的擰入式插裝式閥，以防止在配線和

密封閥體/塊時(shí)將其從擰入式閥體/塊中卸下,。

注意,！

隨著流量增加，系統(tǒng)壓力通過回油管（油口 "T"）中的背壓增加,。

（請(qǐng)遵守 AD2000 - 數(shù)據(jù)表 A2,，第 6.3 項(xiàng)！）

為了讓流量引起的系統(tǒng)壓力增加不超過設(shè)定響應(yīng)壓力的 10%,，

必須根據(jù)回油管（油口 T）中的背壓減少允許的流量,，請(qǐng)參閱
