TDA063EW09B2NXW21由于電磁鐵推力的限制，在大于63L/min的液壓系統(tǒng)中，一般不再選用直推式的電磁換向閥，而選用通過流量較大的電液換向閥。電液換向閥的原理是：控制油通過電磁先導(dǎo)閥到達電液閥主閥芯的兩端（即電液換向閥主閥體兩端蓋側(cè)），通過電磁先導(dǎo)閥的換向，來實現(xiàn)主閥芯的左右移動，從而開通或切斷通往執(zhí)行元件的油路，使執(zhí)行元件運行或停止。但在打開或切斷油路的瞬間，系統(tǒng)中會產(chǎn)生相當大的沖擊，這種沖擊會極大影響液壓系統(tǒng)中液壓元件和密封件的使用壽命。為了減小及至消除由此引起的液壓沖擊，*簡單的辦法是在該電液閥下面疊加一個P口節(jié)流閥或進油節(jié)流式雙單向節(jié)流閥、出油節(jié)流式雙單向節(jié)流閥，以延長閥芯的換向及復(fù)位時間，從而到降低液壓沖擊的目的。下面就以彈簧復(fù)位型、三位四通中封式電液壓換向閥為例、對該三種疊加節(jié)流方式作簡要說明。TDA050EW09B2NXW21
