力士樂REXROTH二通插裝閥，壓力控制功能
LC..DR（插裝閥）
規格 16 … 63
*大流量 1600 l/min
規格 16 … 63
用于壓力功能的二通插裝閥為先導式座閥或滑閥。設計為插裝閥的功率單元安裝在按照 DIN ISO 7368 進行標準化的接收孔內，且使用控制蓋閉合。
用于手動或電動比例壓力調節的先導控制閥作為先導閥集成到控制蓋內或安裝在控制蓋上，其安裝尺寸符合 DIN 24 340。
通過將插裝閥與控制蓋組合，可以實現不同的壓力功能。
減壓功能
靜止位置開啟
用于減壓功能的插裝閥被設計為無面積差的滑閥（在油口 B 處無有效面積）。
作為先導控制閥，應使用具有壓力溢流功能的相同蓋類型（型號 LFA..DB...）。
油口 A 處的有效壓力經先導油供油節流孔引入到閥芯的彈簧側。在性能限制和先導控制閥設定的壓力下，閥芯由彈簧力進行壓力補償并保持在開啟位置，以實現從油口 B 到油口 A 的自由流動。
當達到調定壓力時，閥芯閉合并且油口 A 處的壓力將根據壓力-流體特性降低。

插裝閥在液壓系統中的應用.
插裝閥具有內阻小，結構簡單，工作可靠，標準化程度高，對于大流量、高壓力、較復雜的液壓系統可以顯著的減小尺寸和重量等特點;而實心胎硫化機組液壓系統工作時需要大流量、高壓力油，因而，此系統可以應用插裝閥滿足要求。
一、
插裝閥的工作原理及特點
插裝閥是另一類液壓控制閥的統稱。其基本核心元件是一種液控型、單控制口的裝于油路主級中的兩通液阻單元(故又稱二通插裝閥)。將一一個或若干個插入元件進行不同的組合，并配以相應的先導控制級，可以組成插裝閥的各種控制功能單元。比如方向控制功能單元、壓力控制單元、流量控制單元、復合控制功能單元。
插裝閥具有以下特點:內阻小，適宜大流量工作，閥口多數采用錐面密封，因而泄漏小，對于乳化液等地粘度的工作介質也適宜，結構簡單、工作可靠、標準化程度高;對于大流量、高壓力、較復雜的液壓系統可以顯著的減小尺寸和重量。
其結構:先導閥，控制蓋板，插裝件。
它是由插入元件、控制蓋板、通道塊三大部分組成。插入元件有閥芯、閥套、彈簧和密封件組成;控制蓋板上根據插裝閥的不同控制功能，安裝有相應的先導控制級元件;通道塊既是嵌入插入元件及安裝控制蓋板的基礎閥體，又是主油路和控制油路的連通體。其中A、B為主油路通口，C為控制油路通口。A、B、C油口的壓力和作用面積分別為PA、PB、PC和A1、A2、A3，A3=A1+A2， Fs為彈簧作用力。
二通插裝閥通過不同的蓋板和各種先導閥組合，便可構成方向控制閥、壓力控制閥和流量控制閥。
1、插裝閥構成壓力控制閥
根據插裝閥的工作原理當PAA1+PBA2 >PCA3+FS時，閥芯開啟，油路A、B接通。插裝閥C14，當電磁閥得電時，插裝閥C14的C口直接通油箱，其C口壓力為零。由此可知油路A、B接通，當A口的壓力大于彈簧力的時候，系統壓力油回油箱，所以此插裝閥起溢流閥的作用，控制油缸徑油口壓力。
2、插裝閥構成方向控制閥
由液壓動作程序表可知，同時得電,來控制主油缸上行運動。當兩者同時得電時插裝閥C11、C13的C口通油箱PA>FS時,A、B口直接相通，油液可從A流向B口;當只有一個電磁閥得電時，主油缸下行運動。其中C13的PA<PB,閥芯開啟，油液可從B流向A。此二處插裝閥起到了單向閥的作用。
3、插裝閥構成流量控制閥
在閥的頂蓋上有閥芯升高限位裝置通過調節限位裝置的位置，便可調節閥口通流截面的大小，從而調節了流量。通過調節流量，可調節主油缸的下行速度。此插裝閥作節流閥。
三、
插裝閥在液壓系統的簡單應用，通過更為復雜的組合，可以實現更多的液壓閥的功能。通過組合，插裝閥可作為壓力控制閥(順序閥、減壓閥)、流量控制閥(單向節流閥、節流閥)、方向控制閥(調速閥、液控單向閥、兩位兩通換向閥等)以及復合閥。

數控液壓系統的通過改變壓強增大作用力。一個完整液壓系統由五個部分組成，即動力元件、執行元件、控制元件、輔助元件（附件）和液壓油。數控液壓控制系統要使液壓系統輸出滿足特定的性能要求（特別是動態性能）。數控液壓系統常用的控制方式可分為泵控式系統和閥控式系統兩種。
數控液壓系統一般可分為三類:一是用計算機通過D/A轉換及伺服放大器來控制伺服閥(或比例閥)。另一種是由計算機控制脈寬調制放大器，并操縱高速開關閥工作，第三種是由計算機發出脈沖序列，經驅動電源功率放大后，直接控制帶步進電機的液壓閥動作。
*種控制方式一般都采用閉環控制才能滿足要求，若采用伺服控制，其特點是控制精度高、頻率響應快，但價格昂貴。若采用比例控制，由于比例電磁鐵性能所限，使其滯環、線性度、頻響等均受影向。
后面兩種控制方式:脈寬調制放大器+高速開關閥和由驅動電源+步進電機帶動的閥都叫直接式數字閥(簡稱數字閥)。由數字閥組成的數控液壓系統通常采用開環控制便能滿足精度要求。因此，這種數控液壓系統廣泛應用于機床、工程機械以及石油化工等行業的機械設備。
全閉式數控液壓系統是一種以數控雙向變量泵供油的、閉式回路的、分工況功率匹配的、微機閉環控制的、集節能與控制于一體的機電液一體化節能系統。
采用閉式容積調速回路，不存在節流閥、溢流閥和換向閥，其結構組成比傳動液壓系統簡化，減少了閥口和管路的能量損失；采用數控雙向變量泵供油、分工況功率匹配技術，使系統處于*高效率下工作；采用微機測控技術的多傳感器閉環監控系統可獲得系統佳綜合性能。
系統組成
根據負載運動形式，全閉式數控液壓系統可以組成泵控馬達系統，也可以組成泵控缸系統。與傳統閉式容積調速回路一樣，可以以變量泵-定量馬達、定量泵-變量馬達或變量泵-變量馬達形式工作。采用數控雙向變量泵－變量馬達容積調速液壓系統。
不同的機床液壓系統有不同的功用。像磨床的液壓系統是為了保證機床的平穩運行，減小工作面運行的沖擊力；而鋸床是用液壓系統升降切割速度和夾緊工件用的。
液壓系統的優點1、液壓傳動的各種元件，可以根據需要方便、靈活地來布置。2、重量輕、體積小、運動慣性小、反應速度快。3、操縱控制方便，可實現大范圍的無級調速（調速范圍達2000：1）。4、可自動實現過載保護。5、一般采用礦物油作為工作介質，相對運動面可自行潤滑，使用壽命長。6、很容易實現直線運動。7、很容易實現機器的自動化，當采用電液聯合控制后，不僅可實現更高程度的自動控制過程，而且可以實現遙控。
