用以改變管道內(nèi)氣體流向的控制元件叫方向控制閥。

　　在實(shí)際應(yīng)用中，可根據(jù)不同的需要將方向控制閥分成若干類別：

　?。?）按照氣體在管道的流動(dòng)方向，如果只允許氣體向一個(gè)方向流動(dòng)，這樣的閥叫做單向型控制閥，比如單向閥，梭閥等；可以改變氣體流向的控制閥叫做換向閥，比如常用的2way2port，2way3port，2way5port，3way5port等。

　　（2）按照控制方式可分為電磁閥，機(jī)械閥，氣控閥，人控閥。其中電磁閥又可以分為單和雙電控閥兩種；機(jī)械閥可分為球頭閥，滾輪閥等多種；氣控閥也可分為單氣控和雙氣控閥；人力閥?可以分為手動(dòng)閥，腳踏閥兩種。

　　（3）按工作原理可以分為直動(dòng)閥和先導(dǎo)閥，直動(dòng)閥就是靠人力或者電磁力，氣動(dòng)力直接實(shí)現(xiàn)換向要求的閥；先導(dǎo)閥是由先導(dǎo)頭和閥主體2部分構(gòu)成，有先導(dǎo)頭活塞驅(qū)動(dòng)閥主體里面的閥桿實(shí)現(xiàn)換向。

　?。?）根據(jù)換向閥桿的工作位置可以將閥分為2way，3way閥。

　?。?）根據(jù)閥上氣孔的多少來進(jìn)行劃分，可以分為2port，3port，5port閥。

普通單向閥（逆止閥或止回閥）

　　功用：只允許油液正向流動(dòng)，不許反流。?

　　分類：直通式、直角式　

　　結(jié)構(gòu)：閥體、閥心錐形、鋼球式?、彈簧等?

　　K通壓力油，A?→?B

　　結(jié)構(gòu)特點(diǎn)：B→?A，∵?PB=P工，很高

　　∴?彈簧腔背壓很大，pk很大時(shí)才能頂開閥心,影響可靠性。

　　故?可采用如下措施

　　1)?采用先導(dǎo)閥預(yù)先卸壓

　　2）?采用外泄口回油降低背壓

　　應(yīng)用：∵?液控單向閥具有良好的反密封性

液壓閥作為液壓系統(tǒng)的控制樞紐，運(yùn)動(dòng)頻繁，對(duì)各組成部分器件的精度要求、密封性、可靠性都要求非常高，國外大部分企業(yè)都采用滾壓來提高精度配合，如：日本的小松機(jī)械、日立機(jī)械等，在一些重要部件圖紙中都明確要求滾壓加工。??清洗液壓元件逐步實(shí)現(xiàn)了標(biāo)準(zhǔn)化、系列化，其規(guī)格、品種、質(zhì)量、性能都有了很大提高，尤其是采用電子技術(shù)、伺服技術(shù)等新技術(shù)新工藝后，液壓系統(tǒng)的質(zhì)量得到了顯著的提高，其在國民經(jīng)濟(jì)及軍事工業(yè)中發(fā)揮了重大作用。從不同的角度出發(fā)，可以把液壓系統(tǒng)分成不同的形式。工作壓力：輸入馬達(dá)油液的實(shí)際壓力，其大小決定于馬達(dá)的負(fù)載。油缸是工程機(jī)械最主要部件，傳統(tǒng)的加工方法是：拉削缸體——精鏜缸體——磨削缸體。

?　　1）?梭閥?——相當(dāng)于兩個(gè)單向閥組合的閥

　　具有邏輯"或門"功能.在邏輯回路和程序控制回路中廣泛運(yùn)用,在手動(dòng)---自動(dòng)回路的轉(zhuǎn)換上常用。

　　因梭閥在換向過程中存在路路通過程，因此當(dāng)某一接口進(jìn)氣量或排氣量非常小的時(shí)候，閥的前后不能產(chǎn)生使閥正常換向的壓力差，使閥不能完全換向而中途停止，造成閥的動(dòng)作失靈。所以在使用時(shí)因注意，不要在某一接口處采用變徑接頭造成通路過小。

　　2）雙壓閥?與門功能

　　3)?快速排氣閥?

　　作用：是為了加快汽缸運(yùn)動(dòng)速度作快速排氣的。

　　在給定條件下工作地汽缸殺毒很大程度上取決于控制閥的大小，如需要提高速度（尤其是需要提高單向速度時(shí)），可安裝一個(gè)快速排氣閥，而不必承擔(dān)大型控制閥的費(fèi)用。
