電磁閥應(yīng)用十分廣泛，而使用時(shí)情況卻千差萬(wàn)別，增強(qiáng)通用性能降低制造、購(gòu)銷、存貯、安裝、維護(hù)的成本，近年來(lái)這方面邁出了大步。

(1)響應(yīng)時(shí)間可調(diào)

　　給出電信號(hào)到閥芯動(dòng)作完成的時(shí)間稱為響應(yīng)時(shí)間。不同場(chǎng)合希望開(kāi)關(guān)速度不同，有四種組合：快開(kāi)快關(guān)----用于快速反應(yīng)系統(tǒng);快開(kāi)慢關(guān)----用于防止水錘;慢開(kāi)快關(guān)---用于緩啟急斷; 慢開(kāi)慢關(guān)一一用于平穩(wěn)過(guò)渡。ZDF 多功能電磁閥可方使地調(diào)整于任一狀態(tài)，應(yīng)用十分靈活。

　　(2)擴(kuò)展介質(zhì)適用范固。

　　電磁閥與其它自控閥不同在于介質(zhì)粘度適用范圍較窄，所以空氣、水、蒸汽、油等介質(zhì)對(duì)于先導(dǎo)型電磁閥其結(jié)構(gòu)參數(shù)是不同的;一般地說(shuō)是不能通用的。而ZDF多功能電磁閥只用一顆小螺釘，卻做到了氣、水、油的通用，而且還使油的粘度適用范圍大大加寬，深受歡迎。

　　(3)開(kāi)度可調(diào)與于動(dòng)兼窯

　　電磁閥在使用時(shí)常常還希望它兼具手動(dòng)功能，作為停電或故障時(shí)備用。

　　一般手動(dòng)裝置只能手動(dòng)開(kāi)閥或手動(dòng)關(guān)閥，二者齊備的稱*手動(dòng)。手動(dòng)裝置還能對(duì)閥門開(kāi)度進(jìn)行預(yù)置，一般手動(dòng)只能對(duì)閥的zui大或zui小開(kāi)度進(jìn)行預(yù)置，而*手動(dòng)能分別對(duì)zui大或zui小開(kāi)度進(jìn)行預(yù)置。ZDF多功能電磁閥屬*手動(dòng)類。其它型號(hào)電磁閥根據(jù)需要可帶簡(jiǎn)單的一般手動(dòng)裝置。

電磁閥是用電磁的效應(yīng)進(jìn)行控制，主要的控制方式由繼電器控制。這樣，電磁閥可以配合不同的電路來(lái)實(shí)現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。

　　電磁閥的主要特點(diǎn)

　　(1)外漏堵絕，內(nèi)漏易控，使用安全。內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出，由電動(dòng)、氣動(dòng)、液動(dòng)執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動(dòng)或移動(dòng)。這都要解決*動(dòng)作閥桿動(dòng)密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在隔磁套管內(nèi)的鐵芯完成，不存在動(dòng)密封，所以外漏易堵絕。電動(dòng)閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚至拉斷閥桿頭部;電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏，直至降為零。所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。

　　(2)系統(tǒng)簡(jiǎn)單，便接電腦，價(jià)格低謙。電磁閥本身結(jié)構(gòu)簡(jiǎn)單，價(jià)格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更顯著的是所組成的自控系統(tǒng)簡(jiǎn)單得多，價(jià)格要低得多。由于電磁閥是開(kāi)關(guān)信號(hào)控制，與工控計(jì)算機(jī)連接十分方便。在當(dāng)今電腦普及，價(jià)格大幅下降的時(shí)代，電磁閥的優(yōu)勢(shì)就更加明顯。

　　(3)動(dòng)作快遞，功率微小，外形輕巧。電磁閥響應(yīng)時(shí)間可以短至幾個(gè)毫秒，即使是先導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。由于自成回路，比之其它自控閥反應(yīng)更靈敏。設(shè)計(jì)得當(dāng)?shù)碾姶砰y線圈功率消耗很低，屬節(jié)能產(chǎn)品;還可做到只需觸發(fā)動(dòng)作，自動(dòng)保持閥位，平時(shí)一點(diǎn)也不耗電。電磁閥外形尺寸小，既節(jié)省空間，又輕巧美觀。

　　(4)調(diào)節(jié)精度受限，適用介質(zhì)受限。電磁閥通常只有開(kāi)關(guān)兩種狀態(tài)，閥芯只能處于兩個(gè)極限位置，不能連續(xù)調(diào)節(jié)，(力圖突破的新構(gòu)思不少，但還都處于試驗(yàn)試用階段)所以調(diào)節(jié)精度還受到一定限制。電磁閥對(duì)介質(zhì)潔凈度有較高要求，含顆粒狀的介質(zhì)不能適用，如屬雜質(zhì)須先濾去。另外，粘稠狀介質(zhì)不能適用，而且，特定的產(chǎn)品適用的介質(zhì)粘度范圍相對(duì)較窄。

　　(5)型號(hào)多樣，用途廣泛。電磁閥雖有先天不足，優(yōu)點(diǎn)仍十分突出，所以就設(shè)計(jì)成多種多樣的產(chǎn)品，滿足各種不同的需求，用途極為廣泛。電磁閥技術(shù)的進(jìn)步也都是圍繞著如何克服先天不足，如何更好地發(fā)揮固有優(yōu)勢(shì)而展開(kāi)。

力士樂(lè)比例閥

德國(guó)力士樂(lè)比例閥的閥芯的運(yùn)動(dòng)是采用比例電磁鐵控制，使輸出的壓力或流量與輸入的電流成正比。所以可用改變輸入電信號(hào)的方法對(duì)壓力、流量進(jìn)行連續(xù)控制。有的閥還兼有控制流量大小和方向的功能。力士樂(lè)比例閥根據(jù)功能可分為比例流量閥、比例壓力閥、比例換向閥三大類。以結(jié)構(gòu)形式劃分電液比例閥主要有兩類：一類是螺旋插裝式比例閥(screwin cartridge proportional valve)，另一類是滑閥式比例閥(spool proportional valve)。

力士樂(lè)比例閥常用的型號(hào)有：

德國(guó)力士樂(lè)REXROTH比例閥的螺紋將電磁比例插裝件固定油路集成塊上元件，螺旋插裝閥具有應(yīng)用靈活、節(jié)省管路和成本低廉等特點(diǎn)，近年來(lái)工程機(jī)械上應(yīng)用越來(lái)越廣泛。常用螺旋插裝式比例閥有二通、三通、四通和多通等形式，二通式比例閥主比例節(jié)流閥，它常它元件一起構(gòu)成復(fù)合閥，對(duì)流量、壓力進(jìn)行控制；三通式比例閥主比例減壓閥，也是移動(dòng)式機(jī)械液壓系統(tǒng)中應(yīng)用較多比例閥，它主對(duì)液動(dòng)操作多路閥先導(dǎo)油路進(jìn)行操作。利用三通式比例減壓閥可以代替?zhèn)鹘y(tǒng)手動(dòng)減壓式先導(dǎo)閥，它比手動(dòng)先導(dǎo)閥具有更多靈活性和更高控制精度?？梢灾瞥扇鐖D1所示比例伺服控制手動(dòng)多路閥，不同輸入信號(hào)，減壓閥使輸出活塞具有不同壓力或流量進(jìn)而實(shí)現(xiàn)對(duì)多路閥閥芯位移進(jìn)行比例控制。四通或多通螺旋插裝式比例閥可以對(duì)工作裝置實(shí)現(xiàn)單獨(dú)控制。

德國(guó)力士樂(lè)REXROTH比例閥一種是開(kāi)關(guān)控制：要么全開(kāi)、要么全關(guān)，流量要么zui大、要么zui小，沒(méi)有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。

德國(guó)力士樂(lè)REXROTH比例閥另一種是連續(xù)控制：閥口可以根據(jù)需要打開(kāi)任意一個(gè)開(kāi)度，由此控制通過(guò)流量的大小，這類閥有手動(dòng)控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。

REXROTH力士樂(lè)比例閥比例閥或伺服閥的目的就是：以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制(當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等)，既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。

德國(guó)力士樂(lè)REXROTH比例閥一般來(lái)說(shuō)和換向閥一樣是滑閥結(jié)構(gòu)，只不過(guò)閥芯的換向不是靠電磁鐵來(lái)推動(dòng)，而是靠前置級(jí)閥輸出的液壓力來(lái)推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過(guò)電液換向閥的前置級(jí)閥是電磁換向閥，而伺服閥的前置級(jí)閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。

德國(guó)力士樂(lè)REXROTH比例閥也就是說(shuō)，伺服閥的主閥是靠前置級(jí)閥的輸出壓力來(lái)控制的，而前置級(jí)閥的壓力則來(lái)自于伺服閥的入口p，假如p口的壓力不足，前置級(jí)閥就不能輸出足夠的壓力來(lái)推動(dòng)主閥芯動(dòng)作。

德國(guó)力士樂(lè)REXROTH比例閥其實(shí)缺點(diǎn)極多：能耗浪費(fèi)大、容易出故障、抗污染能力差、價(jià)格昂貴等等等等，好處只有一個(gè)：動(dòng)態(tài)性能是所有液壓閥中zui高的。就憑著這一個(gè)優(yōu)點(diǎn)，在很多對(duì)動(dòng)態(tài)特性要求高的場(chǎng)合不得不使用伺服閥，如飛機(jī)火箭的舵機(jī)控制、汽輪機(jī)調(diào)速等等。動(dòng)態(tài)要求低一點(diǎn)的，基本上都是比例閥的天下了。一般說(shuō)來(lái)，好像伺服系統(tǒng)都是閉環(huán)控制，比例多用于開(kāi)環(huán)控制；其次比例閥類型要多，有比例壓力、流量控制閥等，控制比伺服藥?kù)`活一些。從他們內(nèi)部結(jié)構(gòu)看，伺服閥多是零遮蓋，比例閥則有一定的死區(qū)，控制精度要低，向應(yīng)要慢。但從發(fā)展趨勢(shì)看，特別在比例方向流量控制閥和伺服閥方面，兩者性能差別逐漸在縮小，另外比例閥的成本比伺服閥要低許多，抗污染能力也強(qiáng)！
