六、電磁閥應用
1、2位3通電磁閥控制單作用氣缸:
初始狀態:電磁閥為常閉電磁閥，處于失電狀態，單作用氣缸活塞由彈簧作用在氣缸左側。
工作狀態:電磁閥得電，電磁閥P口與A口通，氣源由A口進入氣缸，氣缸活塞右移。
失電狀態:電磁閥失電，電磁閥A口與R口通，氣缸通過電磁閥放氣，活塞在彈簧作用下回到左側。
2、2位3通電磁閥控制氣動薄膜驅動部:
初始狀態:電磁閥為常閉電磁閥，處于失電狀態，氣動薄膜驅動部的推桿由彈簧作用下停在上位；
工作狀態:電磁閥得電，電磁閥P口與A口通，氣源由A口進入薄膜驅動部上氣室，推動推桿下移；
失電狀態:電磁閥失電，電磁閥A口與R口通，薄膜氣室通過電磁閥放氣，推桿在彈簀作用下回到上位。
3、 2位5通單電控電磁閥控制雙作用氣缸:
初始狀態:電磁閥失電狀態，電磁閥P口與A口相通， 氣源通過A口進入雙作用氣動活塞驅動部左側氣室，活塞停在右側，B口與S口相通，與B口相通的氣動活塞驅動部的右側氣室為排氣狀態；
工作狀態:電磁閥得電，電磁閥P口與B口通，氣源由B口進入雙作用氣動活塞驅動部右側氣室，活塞移動到左側，A口與R口相通， 與R口相通的氣動活塞驅動部的左側氣室為排氣狀態；
失電狀態:電磁閥恢復初始狀態。
4、 2位5通雙電控電磁閥控制雙作用氣缸:左側線圈得電狀態:電磁閥左側線圈得電，電磁閥P口與A口通，氣源由A口進入雙作用氣動活塞驅動部-側氣室，推動活塞到氣缸另一側，B口與S口相通，與B口相通的氣動活塞驅動部的另一側氣室為排氣狀態，在另一側線圈不得電之前會保持該狀態不動；
右側線圈得電狀態:電磁閥右側線圈得電，電磁閥P口與B口通，氣源由B口進入雙作用氣動活塞驅動部一側氣室， 推動活塞到氣缸另一側，A口與R口相通，與A口相通的氣動活塞驅動部的另一側氣室為排氣狀態，在另一側線圈不得電之前會保持該狀態不動。

電磁閥里有密閉的腔，在不同位置開有通孔，每個孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來開啟或關閉不同的排油孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞桿帶動機械裝置。這樣通過控制電磁鐵的電流通斷就控制了機械運動。

一、電磁閥從原理上分為三大類：
    1）直動式電磁閥：
原理：通電時，電磁線圈產生電磁力把關閉件從閥座上提起，閥門打開；斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。
特點：在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。
    2）分步直動式電磁閥：
原理：它是一種直動和先導式相結合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把先導小閥和主閥關閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力先導小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，先導閥利用彈簧力或介質壓力推動關閉件，向下移動，使閥門關閉。
特點：在零壓差或真空、高壓時亦能可*動作，但功率較大，要求必須水平安裝。
    3）先導式電磁閥：
原理：通電時，電磁力把先導孔打開，上腔室壓力迅速下降，在關 閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把先導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。
    特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須達到流體壓差條件。

二、電磁閥從閥結構和材料上的不同與原理上的區別，分為六個分支小類：直動膜片結構、分步直動膜片結構、先導膜片結構、直動活塞結構、分步直動活塞結構、先導活塞結構。
三、電磁閥按照功能分類：水用電磁閥、蒸汽電磁閥、制冷電磁閥、低溫電磁閥、燃氣電磁閥、消防電磁閥、氨用電磁閥、氣體電磁閥、液體電磁閥、微型電磁閥、脈沖電磁閥、液壓電磁閥 常開電磁閥、油用電磁閥、直流電磁閥、高壓電磁閥、防爆電磁閥等。

壓力控制閥
壓力控制閥的作用:
1、用來控制液壓系統中油液壓力;
1)溢流閥：直動式溢流閥、先導式溢流閥
2)減壓閥
2、以壓力為控制信號實現油路通斷。
3)順序閥
4)壓力繼電器
共同工作原理:利用作用于閥心上的液壓力與彈簧力相平衡的原理進行工作。
溢流閥應用實例
(1)為定量泵系統溢流穩壓和定量泵、節流閥并聯，閥口常開。
(2)變量泵系統提供過載保護
和變量泵組合，正常工作時閥口關閉，過載時打開，起安全保護作用,故又稱安全閥。
(3)實現遠程調壓  p遠程< p主調
(4)系統卸荷和多級調壓 和二位二通閥組合(先導式)
(5)形成背壓
減壓閥用于降低并穩定系統中某一支路的油液壓力，常用于夾緊、控制等油路中。
順序閥是一種利用壓力控制閥口通斷的壓力閥，因用于控制多個執行元件的動作順序而得名。按控制油來源不同分內控和外控，按彈簧腔泄漏油引出方式不同分內泄和外泄。
壓力繼電器功用:根據系統壓力變化,自動接通或斷開電路,實現程序控制或安全保護。
工作原理: pk> pT時，柱塞上升,發出信號pk< pT時，柱塞下降,斷開信號。

5.流量控制閥
功用:通過改變閥口過流面積來調節輸出流量，從而控制執行元件的運動速度。
分類:節流閥、調速閥、溫度補償調速閥、分流集流閥。
常用節流口結構有錐形、三角槽形、矩形、三角形等。由節流方程知，當壓力差.定時，改變開口面積即改變液阻就可改變流量。
節流閥實質相當于-一個可變節流口，借助控制機構使閥芯相對于閥體孔運動改變閥口的過流面積。
結構原理
主要零件有閥芯、閥體和螺母。閥體上右邊是進油口，左邊是出油口。閥芯一端開有三角尖槽，另-端加工有螺紋，旋轉閥芯即可軸向移動改變閥口過流面積。為平衡液壓徑向力，三角槽須對稱布置。
調速閥定差減壓閥與節流閥串聯而成，用來調節通過的流量自動補
償負載變化的影響。
插裝閥
上世紀70年代初發展起來的一種新元件，是古老錐閥的新應用。配以蓋板、先導閥組成的-種多功能的復合閥。因每個插裝閥基本組件有且只有兩個油口，故被稱為二通插裝閥。
特點:
閥芯為錐閥，密封性能好，且動作靈敏;
通流能力大，抗污染;
一閥多用，易組成各式系統，結構緊湊。
特別對大流量及非礦物油介質的場合，優點更為突出。
插裝閥基本組件由閥芯、閥套、彈簀和密封圈組成。根據用途不同分為方向閥組件、壓力閥組件和流量閥組件。
插裝閥的應用
單向閥
將方向閥組件的控制口通過閥塊和蓋板上的通道與油口A或B直接溝通，可組成單向閥。
二通閥
由一個二位三通電磁滑閥控制方向閥組件控制腔的通油方式，可組成二位二通閥。
三通閥
由兩個方向閥組件并聯而成，對外形成-一個壓力油口、-一個工作油口和一一個回油口。三通插裝閥的工作狀態數取決于先導換向閥的工作位置數。
四通閥由兩個三通閥并聯而成。
疊加閥以板式閥為基礎，每個疊加閥不僅起到單個閥的功能，而且還溝通閥與閥的流道。換向閥安裝在最上方，對外連接油口開在最下邊的底板上，其他的閥通過螺栓連接在換向閥和底板之間。
