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。


1、移架速度低已成為制約綜采產量的-一個重要因素。為加快移架速度,在支架的液壓系統中采用插裝閥。插裝式方向閥也是采用電磁閥作為先導閥，對主閥(錐閥進行先導控制,控制原理等同于電液操縱閥，但插裝閥的通流能力(可達10000L/min以上大、響應快、工作可靠等突出優點，是管式閥無可比擬的，使其更適于在支架的電液控制系統中使用，而無需研制采用電磁先導控制的專用大流量主閥，既能滿足使用要求,又可改善工作性能,提高通用化程度,從根本上解決由管式閥固有缺陷所產生的問題。
此外，采用插裝閥設計支架液壓系統還具有下列優勢:
(1插裝閥的優點十分適合支架的工況。液壓支架的工況特點是:介質粘度低、工作壓力高、流量大、工作環境惡劣、介質污染嚴重。插裝閥的長處能得到充分發揮。
(2符合流體傳動技術的發展趨勢。為降低使用成本，消除環境污染，流體傳動技術正向著使用純水介質方向發展。液壓支架是用同純水性質比較接近的高水基乳化液作為工作介質，很有可能成為該技術發展成果的受益者,正趨向于采用純水工作介質。由于水的粘度低，要求閥的密封性好,以提高系統的效率。插裝閥采用錐面密封，具有優良的密封性能，更適于在純水介質中工作，應作為純水支架的首選閥種。
(3抗污染能力強、工作可靠。支架工作在采煤面，介質污染程度高，使閥芯磨損嚴重,縮短了閥的使用壽命，由此也導致了支架的各種故障，使工作可靠性降低，增加了維護時間，降低了工作面的生產率。插裝閥的閥芯和閥套間無嚴格的配合要求，磨損輕，不易堵塞,也不會產生液壓卡緊現象，在介質較臟時仍能保證支架液壓系統正常、可靠地工作。
(4滿足某些特殊工況的需要。如用于周期來壓強烈的堅硬且難以冒落頂板的支撐式支架，在老頂突然來壓時，立柱下腔控制閥中的安全閥，要通過很大的瞬時流量,普通安全閥的通流能力遠不能滿足通流要求，因而專門設計了充氣式大流量安全閥，來適應這種工況。但該種閥的結構復雜，制造難度大，裝配要求高,工作可靠性差，很難滿足使用要求。而且，立柱下腔還要裝設普通安全閥來適應正常工況的需要,這無疑會增加元件數量和制造成本。而采用插裝式溢流閥，則能很容易解決這一難題,又會使系統簡化。

2、工作原理分析
基于.上述分析,提出了用插裝閥設計電液控制支架液壓系統的設計思想和方案，其工作原理。該系統由電氣和液壓兩部分組成,內儲支架動作程序的微型計算機中央和支架控制器發出指令后，插裝式方向閥中的電磁先導閥先動作,啟閉相應的兩通錐閥，接通或斷開立柱或推移千斤頂的油路,使之按照-定順序動作。立柱或推移千斤頂的工作狀況由壓力和位移傳感器反饋到控制器，控制器根據反饋信號決定下一個動作。
由于中央控制器和支架控制器相互聯網，故從中央控制器或各架的控制器都可以控制工作面任何--架支架的動作。
中央控制器的作用是控制和協調每臺支架的控制器。此外，還能自動編程，修改系統參數,監測每臺支架的工作狀況,顯示采煤機運行速度等。它可對支架的各個動作進行單獨控制、順序控制、成組控制和全自動控制。支架控制器通過插裝式方向閥直接控制所在支架，同時將傳感器采集的工況數據向其它支架和中央控制器發送。支架液壓系統在接收到信號后，將完成下列動作過程:
(1升架立柱的動作由插裝式方向閥8控制,當方向閥8中先導閥的電磁鐵
1YA通電2YA斷電時，該閥切換到左位,4個2通閥中的b和d的上腔通壓力油,處于關閉狀態,a和c的上腔通油箱,處于開啟狀態，泵站提供的壓力液經2通閥c和液控單向閥，此時液控單向閥中的二位三通先導閥處于位置,工作同于普通單向閥中的2通閥進入立柱的下腔，立柱上腔的乳化液經方向閥8中的二通閥a回液，立柱伸出,實現升架。
立柱的無桿腔油路_上設有插裝式液控單向閥和溢流閥組成的控制閥組，當頂梁接觸頂板，立柱下腔的壓力上升到泵站卸載壓力時,液控單向閥關閉，支架達到初撐力;此后，隨著頂板的下沉,使立柱下腔的壓力上升到溢流閥的調定開啟壓力時，溢流閥開啟卸載,立柱下腔的壓力又降低，當立柱下腔的壓力降低到溢流閥的閉合壓力時，溢流閥又關閉。此后，將重復上述過程，使立柱下腔的壓力在溢流閥的調定值附近變化，支架工作在恒阻支撐狀態。由于插裝閥的響應速度快，使立柱下腔壓力變化小，支架的恒阻支撐性好,利于頂板的管理。
該系統在支架的升架過程中也實現了初撐、增阻和恒阻3個階段，初撐力的大小由泵站壓力決定,工作阻力的大小由溢流閥的調定壓力決定。
(2降架當使插裝式方向閥8中先導閥的電磁鐵2YA通電,1YA斷電時,該閥切換到右位,4個二通閥中的a和c的上腔通壓力油，處于關閉狀
態,b和d的上腔通油箱,處于開啟狀態，泵站提供的壓力液經二通閥b進入立柱的上腔，同時將液控單向閥中的先導閥切換到右位，使其中二通閥的上腔通油箱,處于開啟狀態，立柱下腔的油液經液控單向閥中的二通閥回液，立柱縮回，實現降架。.降架結束后，將方向閥中先導閥置于圖示中間閥位(1YA和2YA均斷電，此時,4個二通閥的上腔均通壓力油,處于關閉狀態，立柱的兩腔油路也均被封閉，支架停留在某一高度位置,準備移架。
(3推溜和移架推移千斤頂的動作由插裝式方向閥9控制,當將方向閥中的先導閥置于右位(4YA通電,3YA斷電和左位(3YA通電,4YA斷電時時,分別控制著推移千斤頂活塞桿的伸出和縮回，實現推溜和移架。推移動作完成后，將先導閥置于中位斷電,4個二通閥的上腔均通壓力油,處于關閉狀態，推移千斤頂的兩腔油路均被封閉,推移動作停止。在接到新的指令后，支架將開始下一個動作循環。
當將方向閥中的電磁先導閥換成手動閥時，即能用插裝閥設計現有手動控制方式支架的液壓系統,以改善支架的工作性能、提高其工作可靠性。分析表明，用插裝:閥設計的電液控制支架的液壓系統，能滿足支架的工作要求,基于同樣的原理，可用插裝閥設計出所有類型和型號的液壓支架的液壓系統。

方向控制閥
方向控制閥用于控制或調節液壓系統或回路中方向及其通和斷,從而控制執行元件的
運動方向及其啟動、停止的閥。如單向閥、換向閥等;
大型鋼廠現場采用的主要方向控制閥，如:電磁換向閥、手動換向閥、電液換向閥、單向閥、方向插件，插裝閥。
3、4WEH..型方向閥
型號4WEH..型方向閥WEH型方向閥是-種電液操作的方向滑閥。它們用于控制液流的開啟、停止和方向。
此類閥組成主要包括閥體( 1 )主控制閥芯(2 )一個或兩個復位彈簧( 3.1 )和(3.2 ),帶一個或兩個電磁鐵:電磁鐵"a” (5.1 ),電磁鐵"b" (5.2 )的先導閥(4)。
主閥閥芯由彈簧或液壓力保持在中位或初始位置。在初始位置, 兩個彈簧腔( 6 )和( 8 )通過先導閥無壓的油箱連通。經過控制油路(7 )向先導閥(4)供油。控制泊可以由內部或外部供給( 外部供給油口X )當先導閥操作時,如電磁鐵"a”得電,先導滑閥(10)向左移動,因此彈簧腔(8)獲得先導油壓力而彈簧腔(6)保持無壓狀態。
先導壓力施壓于主閥芯的左端, 并克服彈簧力( 3.1),其結果,主閥的P至B和A至T被接通。當電磁鐵斷電,先導閥回復至初始位置(帶定位機構滑閥除外),彈簧腔( 8 )向油箱卸荷。
控制油從彈簧腔經先導閥排入Y口。控制油可內部或外部供油和回油外部經油口Y )可選擇的應急手動操作( 9 ),在電磁鐵不通電情況下,可對先導滑閥( 10 )進行操作。
2、LC..型二通插裝閥
二通插裝閥設計成插件結構, 用于整體集成塊。帶油口A和B的主閥組件插入控制塊上尺寸符合DIN ISO 7368標準的插孔,并用控制蓋板封閉。在大多數情況下,蓋板的作用,就是作為主閥組件控制側與先導閥之間的連接件。采用適合的先導閥來控制主閥，主閥組件能承擔壓力、方向或者節流功能、或它們的組合功能。通過不同通徑的閥和執行器獨特的流量變化需要相匹配,可以實現特殊的經濟型結構設計。如果主閥組件能承擔一種以上的功能,特殊的經濟型結構就能達到。
方向功能
二通插裝閥的基本組成主要包括控制蓋板( 1 )和插件(2 )控制蓋板含有控制孔、根據功能需要可選擇的行程限位器、液壓控制的方向座閥或梭閥。另外,方向滑閥或方向座閥可以安裝在控制蓋板的上面。插件的組成主要包括閥套(3 )調整圈( 4 )(僅適用至通徑32)座閥(5)可選擇帶阻尼錐頸(6)或不帶阻尼錐頸(7)以及復位彈簧(8)
功能說明
二通插裝閥的驅動取決于壓力。因此對閥的驅動，這里有三個重要的承壓面積: A1, A2, A3閥座的面積( A1 )作為100%、根據類型環形面積( A2 )為面積( A1的7%或50%。因此面積比A1:A2或是14,3:1 ,或是2:1。面積( A3 )等于A1 + A2。由于A1:A2面積比不同,因此,環形面積A2也不同。面積A3在閥座面積A1為100%時，可能是107%,也可能是150%。
基本應用:
面積A1和A2的作用在閥開啟方向。面積A3和彈簧的作用在閥關閉方向。合成力的有效方向(開啟力或關閉力) 決定了兩通插裝閥的開關狀
態。二通插裝閥的流動方向可以從A至B ,也可以從B至A.如果作用于面積A3的控制壓力來自油口B或者控制油由外部供給,油口A則關閉,且無泄漏。

四、流量控制閥
流量控制閥用于控制或調節液壓系統或回路中工作液體流量大小的閥。如節流閥、調速閥、分集流閥等
大型鋼廠現場采用的主要流量控制閥，如：二通流量控制閥、疊加式流量控制閥、雙單向節流閥，單向閥、節流閥、液壓鎖。
1、Z2FS...型雙單向節流閥
1.結構分析
Z2FS16型閥是疊加式設計的雙路單向節流閥。該閥用于限制來自一個或兩個工作油口的主流量或控制流量。
兩個對稱設置的單向節流閥在一個方向上限定流量,(通過調整節流閥芯),在相反方向上允許自由流通。用于進口節流控制時, 油液從油口A流經節流口( 1 )到達工作油口。節流閥芯( 4.1 )可借助于調節螺釘( 5 )進行軸向調整,從而可以設定節流口(1 )同時,油口A中的油液通經道( 2 )到節流閥芯( 4.1 )的彈簧加載側(3 )產生的壓力與彈簧
共同作用,使節流閥芯( 4.1 )保持在節流位置,
油液從執行器回流推動節流閥芯( 4.2 ),允許油液自由流過。此時閥作為單向閥工作。根據型號(S或S2 ),節流口可以起進口或出口節流的控制作用。限制主流量為了改變執行器的速度(主流量限制),雙路單向節流閥是而安裝于方向控制閥和底板之間。限制控制流量對液控方向閥,雙路單向節流閥用作控制阻尼調節,在此情況下,它被安裝于主閥和控制閥之間。

五、比例控制閥
采用比例電磁鐵(或力矩馬達)將輸入信號轉換成力或閥的機械位移，使閥的輸出(壓力、流量)也按照其輸入量連續、成比例地進行控制的閥。
大型鋼廠現場使用的比例閥主要有下表中的幾種:伺服比例控制閥、比例控制閥、電液比例控制閥，比例閥，伺服閥。
1、4WRD E..型比例伺服控制閥(高頻響閥)
結構和功能
4WRDE型閥是三級高頻響方向閥。該閥可用于開環控制或閉環調節液流的大小和方向，但主要用于閉環調節回路中。
閥主要由下列部分組成:
1.二級先導控制閥由力矩馬達( 1 )和由噴嘴擋板閥構成的液壓放大器( 5),和用作流量放大級的閥芯襯套組件(6 )(用以控制第三級(7 ))組成。
2.第三級(7)用于流量控制。
3.感應式位移傳感器( 8),連接第三級主閥芯( 10)的磁芯(9 )
通過內置電子放大器實現閥閉環控制信號邏輯連接,位置檢測系統反饋,和先導閥的控制。
給定值/實際值比較得到的差動電壓經過電子控制器放大, 并作為控制偏差量傳遞到閥的一級。這個信號推動兩個控制噴嘴( 3.1, 3.2) 之間的擋板( 2)因而在兩個控制腔(11.1.11.2)產生了壓差。控制閥芯(4 )因此被推動,并通過相應的液流流到彈簧腔(12.1or12.2)閥芯(10)和帶磁芯(9)的位移傳感器(8)-直運動,直到實際值和給定值信號再一次相等。在控制條件下;主閥芯( 10 )一直被保持在給定值所對應的位置。
閥芯行程和給定值成正比。通過閥芯( 10 )相對于控制邊( 13 )的位置,形成相應的與流量成正比的閥口開度。
閥的動態特性通過電子放大器優化。電子放大器內置于閥上(振蕩器,解調器)
零點調節由廠家預先設定,通過閉環控制電子放大器內的電位器, 零點能在名義行程士10%范圍內調整。移去閥蓋尾部的插頭,可以對內置閉環電子放大器進行操作。
