DSL201CR座閥型二通電磁閥

液壓電磁閥采用電氣操控的方式切換閥內(nèi)的滑閥或座閥芯的位置,將液壓液流導(dǎo)入及導(dǎo)出執(zhí)行機構(gòu),這類閥可以是二通、三通、四通, 或者甚至是五通, 并均采用一個或兩個電磁鐵進行操控換向。

派克的二通座閥是先導(dǎo)式操控的,由低泄漏電磁鐵進行驅(qū)動的二通方向閥。

在電磁鐵失電的狀態(tài)下,此類閥類似于一個單向閥,在一個方向上將液流截止,且泄漏量極小(每分鐘5滴,或更小),而當電磁鐵得電時,則將允許液流通過。

典型地要選用此類閥,是由于它們的低泄漏特性,以及能滿足大流量要求的通流能力。

座閥型閥通常用于單作用執(zhí)行機構(gòu)或卸荷功能。它們可以是常閉或是常開,而反向允許液流自由通過,并有快速響應(yīng)型式可選。

派克的二位二通座閥由主級座閥、復(fù)位彈簧、先導(dǎo)活塞以及電磁線圈組成。

該類閥的常閉型式在失電狀態(tài)下類似于一個單向閥,它在一個方向上截止液流,而在相反方向(油口1至油口2)上則允許經(jīng)節(jié)流的液流自由通過。

當電磁線圈得電時,座閥芯被先導(dǎo)操控而開啟(閥芯抬起),允許經(jīng)節(jié)流的液流在原先截止的方向上通過,典型地,該流向為側(cè)面油口2至底部油口1。

如果要求反向液流自由通過,則應(yīng)選擇"反向自由流動"選項。

該類閥的常開型式在失電狀態(tài)下,允許液流在閥的側(cè)面油口(油口2)至底部油口(油口1)方向上自由流過。

反向液流為經(jīng)過節(jié)流,如果要求反向自由流動,則應(yīng)選擇"反向自由流動"選項。

工作原理:常閉型閥的閥芯由復(fù)位彈簧將其壓靠在閥座上,先導(dǎo)液流被關(guān)閉,進油口(油口2)的壓力作用在主閥芯內(nèi)腔,使之保持壓靠在閥座上,阻止液流通過該閥(油口2至油口1)。

此時若插件底部(油口1)的壓力高至足以克服復(fù)位彈簧的作用力,則將推動閥芯,使之離開閥座,允許液流從油口1至油口2方向流過。

電磁線圈得電,將先導(dǎo)閥芯拉離其在主閥芯上的閥座,主閥芯內(nèi)的壓力泄向油口1,這就使得主閥芯兩端的壓力建立起平衡,于是主閥芯側(cè)面的進油壓力將其抬起,允許液流從側(cè)面向底部(2至1)流過。

由于該型閥是先導(dǎo)操控的,在液流從油口2和1之間流過的同時,必須建立起一個最小的壓力差(25-50psi),以克服彈簧力而保持閥芯的開啟狀態(tài)。

常開型閥的先導(dǎo)閥在偏置彈簧的作用下保持開啟狀態(tài),先導(dǎo)液流泄向油口1,并在主閥芯的兩端建立起壓力平衡,由此移動主閥芯,使之開啟,允許液流從側(cè)面流向底部(2至1),同時在兩油口(2和1)之間保持一個最小壓差(25-50psi),以克服主閥彈簧力,使主閥保持開啟狀態(tài)。

電磁線圈得電,推動先導(dǎo)閥芯壓靠在其閥座上,關(guān)閉主閥內(nèi)腔泄向油口1的通道,主閥內(nèi)腔的壓力升高至與進油口(油口2)相同,主閥芯在該壓力的作用下壓靠在其閥座上,這樣就截止了從油口2流向油口1的液流。

此時若插件底部(油口1)壓力升高,可以克服彈簧力和電磁力,推動閥芯脫離閥座,允許經(jīng)節(jié)流的液流通過該插件(油口1至2方向)。

派克的座閥型電磁閥還有反向全流量自由流動和快速響應(yīng)的型式,反向全流量自由流動型式允許油液在底部至側(cè)面油口(1至2)的方向上無節(jié)流地自由通過,而快速響應(yīng)型閥的換向時間在數(shù)豪秒以內(nèi)。

由于此類閥是先導(dǎo)操控的,閥芯的移動距離較短,這就限制了這類閥的通流能力。

此類二位二通座閥的常用市場和應(yīng)用工況是負載需要在低泄漏狀態(tài)下鎖定位置的一類系統(tǒng),架空裝置,如:叉車和翻斗卡車,使用這一類閥。

其它的應(yīng)用包括液壓泵卸荷回路,該回路要求系統(tǒng)在工作時泄漏小,而在低壓大流量卸荷期間壓降小。
