博士力士樂清洗與溢流閥塊的工作油口 A 與 B 都可按用戶的要求,連接高壓或低壓油液。由高壓控制的清洗滑閥,可確保在進(jìn)行高-低油壓端的切換時(shí),使清洗閥可靠地與低壓油口相連。
由于博士力士樂SDVB型閥塊為雙向作用式溢流閥采用先導(dǎo)控制功能,因而只需很小的操縱力就能設(shè)置油路兩個(gè)高壓端所需要的壓力值。這些設(shè)定值的設(shè)置,可以相互獨(dú)立地進(jìn)行。對(duì)于規(guī)格 30 和 50 閥塊,還可通過外部先導(dǎo)油口(X 和 Y)實(shí)現(xiàn)遠(yuǎn)程控制功能。一旦啟動(dòng)了溢流閥,高壓端的液壓油就可以流向低壓端。設(shè)定的壓力值,對(duì)應(yīng)于高、低壓之間的壓降值。與這種閥的通流 能力相比,其結(jié)構(gòu)極為緊湊。
博士力士樂SDVB型清洗與溢流閥塊還可用作一種雙向作用式溢流閥。在用作溢流閥 時(shí),清洗閥的供油管路應(yīng)當(dāng)處于封閉狀態(tài)。 采用單獨(dú)或直接安裝的卸載閥之后,既可以通過外部將先導(dǎo)閥與 油箱相連,也可以在內(nèi)部與低壓端相連。利用這一項(xiàng)功能,就可 以將 SDVB 30 和 50 用作旁通閥。對(duì)于采用SDVB 型沖洗與溢流 閥塊的高動(dòng)態(tài)運(yùn)行,在改變了高壓端之后油口A 和 B 之間仍會(huì)有 短時(shí)間的自由流動(dòng)。這種應(yīng)用適合使用直動(dòng)式閥塊;為此,我們 可根據(jù)用戶要求提供 16和 30 兩種規(guī)格的產(chǎn)品。

博士力士樂SDVB型清洗與溢流閥塊的技術(shù)數(shù)據(jù) (部分依照 VDI 3276)
設(shè)計(jì):組合了清洗閥與溢流閥的結(jié)構(gòu)設(shè)計(jì),并由工作壓力進(jìn) 行控制。
安裝:法蘭安裝,配 O 形密封圈(機(jī)罩上設(shè)有四個(gè)安裝孔)
管路接口和規(guī)格:參見元件尺寸 重量(kg)
規(guī)格 16 30 50
不帶底板 6,5 23 61
帶底板 30 68
安裝位置:可選
液流方向: 分別從 A 到 B(對(duì)應(yīng)于從 B 到 A)、以及從 A 到 K 1(對(duì)應(yīng)于從 B 到 K1 )
工作壓力范圍: pN = 0…400 bar 只要溢流閥尚未啟動(dòng),油口 XA/B 測(cè)得的壓力就僅僅為工作管 路中的壓力而已。而一旦先導(dǎo)閥開始打開閥塊,主油路中的 工作壓力就會(huì)上升約 15%。因此,我們建議在MA 或 MB(分 別對(duì)應(yīng)于A 或 B)直接測(cè)量工作壓力。
壓力設(shè)定范圍: 工作壓力: pv min…pv max = 50…400 bar SDVB 16、30 和 50 在公稱流量 qNSp 時(shí)的清洗壓力:均為 無限可調(diào)。訂購時(shí),請(qǐng)注明要求的工作壓力和清洗壓力設(shè)置 值。更多詳情請(qǐng)參見 RC 92100。
油液的溫度范圍: ϑm min…ϑm max = –20° C…+80° C
粘度范圍: νmin…νmax = 10…1000 mm2 /s
切換壓力——為了在兩個(gè)方向上實(shí)現(xiàn)清洗閥回路 A 和 B的切換,就必須在高壓 和低壓端之間建立起一個(gè)壓差。 這一壓差、以及由此在高壓端形成的切換壓力,與低壓端的設(shè)定 值有關(guān)。而對(duì)于 SDVB 30 和 50,還必須考慮彈簧力的作用,因 為這種作用相當(dāng)于還需再上升約 9 bar 的壓力,才能使閥口* 打開(參見左圖)。
先導(dǎo)油液的zui大流量 QSt max (taken from main circuit)
規(guī)格 16 30 50
QSt max (L/min) ≈4 ≈5 ≈6
遠(yuǎn)程控制——為了能設(shè)置溢流閥的不同壓力值,提供了遠(yuǎn)程控制所需要的外部先導(dǎo)油口"X"和"Y"。
功能型式——SDVB 16 至 50 的閥,還可作為雙向作用的溢流閥使用。 如果僅僅需要雙向作用的溢流閥功能, 就可以封閉清洗閥上的供 油管路, 或者將清洗閥的壓力設(shè)為高于低壓端的相應(yīng)值即可。
博士力士樂SDVB型清洗與溢流閥塊為A4VSG和A2P柱塞泵的控制元件。Rexroth清洗與溢流閥塊的作用是:保持輸送壓力并排出多余的油液,以限制閉式液壓回路中的工作壓力。 博士力士樂SDVB清洗與溢流閥塊還可用作一種雙向作用式溢流閥。在用作溢流閥時(shí),清洗閥的供油管路應(yīng)當(dāng)處于封閉狀態(tài)。我公司在為您提供力士樂軸向柱塞泵的情況下,我們還為您提供該產(chǎn)品的控制元件——SDVB型清洗與溢流閥塊。
