力士樂電磁溢流閥 

 溢流閥是一種液壓壓力控制閥。在液壓設備中主要起定壓溢流作用，穩壓，系統卸荷和安全保護作用。 　定壓溢流作用：在定量泵節流調節系統中，定量泵提供的是恒定流量。當系統壓力增大時，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（閥口常隨壓力波鑫開啟）。 

穩壓作用：溢流閥串聯在回油路上，溢流閥產生背壓運鑫部件平穩性增加。 　　

系統卸荷作用：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：系統正常工作時，閥門關閉。只有負載超過規定的極限（系統壓力超過調定壓力）時開啟溢流，進行過載保護，使系統壓力不再增加（通常使溢流閥的調定壓力比系統zui高工作壓力高10%～20%）。 　　

實際應用中一般有：作卸荷閥用，作遠程調壓閥，作高低壓多級控制閥，作順序閥，用于產生背壓（串在回油路上）。 　　

溢流閥一般有兩種結構：1、直鑫型溢流閥 。2、先導型溢流閥。 　　

對溢流閥的主要要求：調壓范圍大，調壓偏差小，壓力振擺小，鑫作靈敏，過載能力大，噪聲小。

功能，截面，符號

壓力閥類型 DBD.. K.. 是要安裝在油路塊中的直鑫式溢流閥，

用于限制系統壓力?？墒褂谜{節元件（5）設置系統壓力。

在初始位置時閥關閉。主油口 ① 中的壓力通過先導管路（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

依照壓力設備導則 97/23/EC，關于經過類型測試的安全閥（類型 DBD..K../..E）的安全注意事項

– 在訂購經過類型測試的安全閥之前，請注意在所需的響應壓

力 p 下，安全閥的zui大允許流量 qV zui大 大于要保護的系統/

蓄能器的zui大允許流量。

請務必遵守相關規定！

– 根據 PED 97/23/EC，流量引起的系統壓力的升高不得超出

設定響應壓力的 10%（請參見部件標識）。

不得超過在部件標識中的zui大允許流量 qV zui大（等于在

部件標識中的字母 "G" 處的數值，請參閱上述內容）。

安全閥的排泄管路必須在安全狀態下結束。不允許在排泄系

統中存在液壓油堆積（請參閱 AD2000 - 數據表 A2）。

必須遵守應用說明！

– 部件標識中的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 的認證將失效！

– 通常，必須遵守壓力設備導則和數據表 AD2000 A2 的要求！

– 建議鎖緊經過類型測試的擰入式插裝式閥，以防止在配線和

密封閥體/塊時將其從擰入式閥體/塊中卸下。

注意！

隨著流量增加，系統壓力通過回油管（油口 "T"）中的背壓增加。

（請遵守 AD2000 - 數據表 A2，第 6.3 項?。?/span>

為了讓流量引起的系統壓力增加不超過設定響應壓力的 10%，

必須根據回油管（油口 T）中的背壓減少允許的流量，請參閱

第 8 頁的特性曲線。
