4WRKE16R200L-3X/6EG24EK31/A1D3M比例方向閥

伺服閥，

1、基本結(jié)構(gòu)：

主閥體（閥芯/閥套）、先導(dǎo)閥（伺服射流管）、電氣控制盒（放大版）

2、工作原理

伺服射流管先導(dǎo)級(jí)

射流管先導(dǎo)級(jí)主要由力矩馬達(dá)、射流管和接收器組成。

當(dāng)線圈中有電流通過(guò)時(shí),產(chǎn)生的電磁力使射流管?chē)娮炱x零位,管內(nèi)的大部分液流集中射向一側(cè)的接收器,而另一側(cè)接收 器所得到的流量減少,由此造成兩接收器的壓力變化。主閥閥芯因此壓差而產(chǎn)生位移。

先導(dǎo)級(jí)的泄漏油通過(guò)噴嘴環(huán)形區(qū)域處的排出通道直接回油箱。

多級(jí)閥的工作原理

多級(jí)閥中的功率級(jí)閥芯的位置閉環(huán)控制是由閥內(nèi)控制電路來(lái)實(shí)現(xiàn)的。對(duì)控制電路中的位移控制器輸入一個(gè)指令信號(hào)(與閥期望輸出的流量成正比),同時(shí)位移傳感器通過(guò)一激勵(lì)器測(cè)出功率級(jí)閥芯的實(shí)際位移(以與實(shí)際位移成正比的電壓形式出現(xiàn)),次位移信號(hào)被調(diào)解并反饋至位移控制器與指令信號(hào)相比較,得出的偏移信號(hào)驅(qū)動(dòng)先導(dǎo)級(jí)并使功率級(jí)閥芯

產(chǎn)生位移,直至偏差信號(hào)為零。

比例控制閥可分為壓力控制閥，流量控制及方向控制閥三類。

壓力控制閥:用比例電磁閥取代引導(dǎo)式溢流閥的手調(diào)裝置便成為引導(dǎo)式比例溢流閥，其輸出的液壓壓力由輸入信號(hào)連續(xù)或按比例控制。

流量控制閥:用比例電磁閥取代節(jié)流閥或調(diào)速閥的手調(diào)裝置而以輸入信號(hào)控制節(jié)流閥或調(diào)速閥之節(jié)流口開(kāi)度，可連續(xù)或按比例地控制其輸出流量。故節(jié)流口的開(kāi)度便可由輸入信號(hào)的電壓大小決定。

方向控制閥:比例電磁閥取代方向閥的一般電磁閥構(gòu)成直動(dòng)式比例方向閥，其滑軸不但可以換位，而且換位的行程可以連續(xù)或按比例地變化，因而連通油口間的通油面積也可以連續(xù)或按比例地變化，所以比例方向控制閥不但能控制執(zhí)行元件的運(yùn)動(dòng)方向外，還能控制其速度。

液壓元件系統(tǒng)由五個(gè)部分組成，即動(dòng)力元件、執(zhí)行元件、控制元件、輔助元件和液壓油。動(dòng)力

元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能，指液壓系統(tǒng)中的油泵，它向整個(gè)液壓系統(tǒng)提供動(dòng)力。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵和柱塞泵。執(zhí)行元件(如液壓缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。 控制元件(即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。根據(jù)控制功能的不同，液壓閥可分為壓力控制閥、流量控制閥和方向控制閥。壓力控制閥又分為溢流閥(安全閥)、減壓閥、順序閥、壓力繼電器等；流量控制閥包括節(jié)流閥、調(diào)整閥、分流集流閥等；方向控制閥包括單向閥、液控單向閥、梭閥、換向閥等。根據(jù)控制方式不同，液壓閥可分為開(kāi)關(guān)式控制閥、定值控制閥和比例控制閥。 輔助元件包括油箱、濾油器、油管及管接頭、密封圈、壓力表、油位油溫計(jì)等。 液壓油是液壓系統(tǒng)中傳遞能量的工作介質(zhì)，有各種礦物油、乳化液和合成型液壓油等幾大類。
