產(chǎn)品簡介：

力士樂REXROTH二通插裝閥,，壓力控制功能

LFA..DB（標(biāo)準(zhǔn)）

規(guī)格 16 … 100

大工作壓力 420 bar

規(guī)格 16 … 100

用于壓力功能的二通插裝閥為先導(dǎo)式座閥或滑閥。設(shè)計為插裝閥的功率單元安裝在按照 DIN ISO 7368 進(jìn)行標(biāo)準(zhǔn)化的接收孔內(nèi),，且使用控制蓋閉合,。

用于手動或電動比例壓力調(diào)節(jié)的先導(dǎo)控制閥作為先導(dǎo)閥集成到控制蓋內(nèi)或安裝在控制蓋上,，其安裝尺寸符合 DIN 24 340。

通過將插裝閥與控制蓋組合,，可以實現(xiàn)不同的壓力功能,。

壓力溢流功能

用于壓力溢流功能的插裝閥（型號 LC .DB...）被設(shè)計為無面積差的座閥（在油口 B 處無有效面積）。油口 A 處的有效壓力經(jīng)先導(dǎo)油供油節(jié)流孔導(dǎo)入到元件的彈簧側(cè),。在先導(dǎo)控制閥上設(shè)定的壓力下，閥芯 由彈簧力進(jìn)行壓力補(bǔ)償和閉合,。

當(dāng)達(dá)到調(diào)定壓力時,，閥芯 開啟，且油口 A 處的壓力將根據(jù)壓力-流體特性而受到限制,。

減壓功能

靜止位置開啟

用于減壓功能的插裝閥被設(shè)計為無面積差的滑閥（在油口 B 處無有效面積）,。

作為先導(dǎo)控制閥，應(yīng)使用具有壓力溢流功能的相同蓋類型（型號 LFA..DB...）,。

油口 A 處的有效壓力經(jīng)先導(dǎo)油供油節(jié)流孔引入到閥芯的彈簧側(cè),。在性能限制和先導(dǎo)控制閥設(shè)定的壓力下，閥芯由彈簧力進(jìn)行壓力補(bǔ)償并保持在開啟位置,，以實現(xiàn)從油口 B 到油口 A 的自由流動,。

當(dāng)達(dá)到調(diào)定壓力時，閥芯閉合并且油口 A 處的壓力將根據(jù)壓力-流體特性降低,。
