液壓系統(tǒng)換向閥易產(chǎn)生的問題分析
（一）二位四通換向閥的問題
在有些設(shè)計(jì)中，常出現(xiàn)由二位四通換向閥代替二位二通換向閥的情況。二位四通換向閥可根據(jù)需要通過堵A口或B口，從而改成常閉型或常開型二位二通換向閥[見圖3(a)]。在應(yīng)用時(shí)，管式連接直接堵口即可達(dá)到預(yù)期的目的，板式連接在加工連接板時(shí)相應(yīng)的孔不加工即可。但應(yīng)該注意，四通閥0口不能堵塞，須接通油箱，用作泄油口。因?yàn)槿绻鸒口堵塞， 液壓系統(tǒng)開始工作時(shí)，啟動(dòng)換向閥可以換向，液壓系統(tǒng)能夠正常工作，時(shí)間一長，泄漏到彈簧腔的液壓油無處外漏，從而使換向閥不能換向，液壓系統(tǒng)就不能正常工作。
（二）電液換向閥的問題
電液換向閥按控制油路的進(jìn)、回油方式分為：內(nèi)控內(nèi)泄式、內(nèi)控外泄式、外控內(nèi)泄式、外控外泄式四種。在產(chǎn)品樣本和有些手冊(cè)中并不是四種形式羅列完善的，有時(shí)選型時(shí)選了，但購買時(shí)沒貨，還需要自己動(dòng)手去加以改造，因此必須對(duì)電液換向閥的結(jié)構(gòu)了解清楚，以獲得自己需要的換向閥形式。對(duì)于外控式換向閥，由于控制油是從電液換向閥之外的油路單獨(dú)引入的，在使用時(shí)，無論內(nèi)泄還是外泄，均不存在什么問題；而對(duì)于內(nèi)控式換向閥，由于先導(dǎo)閥的供液口與主閥的P口是掏通的，結(jié)構(gòu)簡(jiǎn)單，使用方便，但如果閥中位機(jī)能為M、H、K、X等時(shí)，在中位時(shí)主油路不能為控制油路提供主閥芯換向所必須的控制壓力，因此，必須對(duì)閥或 液壓系統(tǒng)采取措施（如采用預(yù)壓閥或增大回油背壓等方法）以滿足電液換向閥的使用要求。
