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(lèi)別：

　　（1）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。

　?。?）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(lái)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(lèi)：直通式、直角式　

　　結(jié)構(gòu)：閥體、閥心錐形、鋼球式?、彈簧等?

　　工作原理：液流從進(jìn)油口流入時(shí)，A?→B

　　液流從出油口流入時(shí)，A?→?B

　　開(kāi)啟壓力：0、04——0、1MPa

　　做背壓閥：Pk=0.2——0.6?MPa?3

液控單向閥

　　功用：正向流通，反向受控流通

　　結(jié)構(gòu)：普通單向閥+液控裝置

　　K不通壓力油，A?→?B

　　工作原理〈

　　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(kāi)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

　　∴?常用于保壓、鎖緊和平衡回路

梭閥、雙壓閥和快速排氣閥

　　1）?梭閥?——相當(dāng)于兩個(gè)單向閥組合的閥

　　具有邏輯"或門(mén)"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(guò)程中存在路路通過(guò)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(guò)小。

　　2）雙壓閥?與門(mén)功能

　　3)?快速排氣閥?
