力士樂(lè )REXROTH先導式單向閥

SV 6

規格 6

組件系列 6X

大工作壓力 315 bar

大流量 60 l/min

用于底板安裝

油口安裝面符合  ISO 4401-03-02-0-05 和  ISO 5781-03-04-0-00

用于一個(gè)執行機構油口的無(wú)泄漏阻塞

帶內部先導油回油

具有多種開(kāi)啟壓力，可選

帶或不帶預開(kāi)口，可選

單向閥安裝套件可單獨使用

耐腐蝕設計，可選

SV 型單向閥是用于底板安裝的先導式單向閥。用于一個(gè)執行機構油口的無(wú)泄漏阻塞，甚至能夠用于長(cháng)期停機的情況。

該閥主要由殼體、提升座閥、壓縮彈簧、控制閥芯以及可選預開(kāi)口球座閥組成。

座閥允許流體從方向 A 流向 B，而無(wú)需外部先導壓力。

條件： pA > pB + 開(kāi)啟壓力（壓縮彈簧）。在相反方向上，座閥以液壓方式緊閉。

油口 X 處的高先導壓力足以使控制閥芯沿座閥方向移動(dòng)，并推動(dòng)提升座閥離開(kāi)其閥座。這便實(shí)現了兩個(gè)方向上的自由流動(dòng)（主動(dòng)保持

打開(kāi)）。

為確保座閥主動(dòng)打開(kāi)，控制閥芯兩側上的壓力比與提升座閥或上的面積比同樣重要。

因此，提供了以下不同類(lèi)型

SV（連接至 pA 的大閥芯端面 A2）或?

以及帶預開(kāi)口“A”和不帶預開(kāi)口“B”的型號。

型號“A”（帶預開(kāi)口）

該閥配有一個(gè)附加的預開(kāi)口。通過(guò)對油口 X 加壓，控制閥芯將向右移動(dòng)。這樣一來(lái)，滾珠和提升座閥將先后被推出閥座。

注意！

型號“A”：

由于使用的是具有擴大的開(kāi)口控制面積比的兩層結構，使用較低的先導壓力也可以安全卸載。?

避免由于執行機構側的壓力容積的衰減降壓而導致的換向沖擊。?

型號“B”：

閥門(mén)不帶預開(kāi)口時(shí)，可能會(huì )突然卸載所含的壓力容積。產(chǎn)生的換向沖擊不但會(huì )導致安裝組件的過(guò)早磨損，還會(huì )形成噪音。?

替換插頭和可實(shí)現從 SV 型號到 SL 型號的修改。必須始終安裝其中一個(gè)插頭！

防腐蝕設計

SV 型單向閥是用于底板安裝或螺紋連接的先導式單向閥。用于一個(gè)執行機構油口的無(wú)泄漏阻塞，甚至能夠用于長(cháng)期停機的情況。

該閥門(mén)主要由殼體、提升座閥、壓縮彈簧、控制閥芯以及可選預開(kāi)口球座閥 組成。

座閥允許流體從 A 流向 B，而無(wú)需外部先導壓力。在相反方向上，座閥以液壓方式緊閉。

條件： pA > pB + 開(kāi)啟壓力（壓縮彈簧）。

油口 X 處的高先導壓力足以使控制閥芯沿球座閥（型號“A”）方向移動(dòng)，并推動(dòng)提升座閥離開(kāi)其閥座。這便實(shí)現了兩個(gè)方向上的自

由流動(dòng)（主動(dòng)保持打開(kāi)）。

為確保座閥主動(dòng)打開(kāi)，控制閥芯兩側上的壓力比與控制閥芯或提升座閥上的面積比同樣重要。

因此，為 SV 型（大環(huán)形區域）提供了帶預開(kāi)口“A”和不帶預開(kāi)口“B”的型號。 A3 ; with pA 已連接）。

型號“A”（帶預開(kāi)口）

該閥配有一個(gè)附加的預開(kāi)口。通過(guò)對油口 X 加壓，控制閥芯將向右移動(dòng)。這樣一來(lái)，滾珠 和提升座閥將先后被推出閥座。

注意事項：

型號“A”：

由于使用的是具有擴大的開(kāi)口控制面積比的兩級設置，使用較低的先導壓力也可以安全卸載。‐

避免由于執行機構側壓力容積的衰減降壓而導致的換向沖擊。‐

型號“B”：

閥門(mén)不帶預開(kāi)口時(shí)，可能會(huì )突然卸載所含的壓力容積。產(chǎn)生的換向沖擊不但會(huì )導致安裝組件的過(guò)早磨損，還會(huì )形成噪音。
