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的滑閥或座閥芯的位置,將液壓液流導入及導出執(zhí)行機構,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式操控的,由低泄漏電磁鐵進行驅動的二通方向閥。

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,并有快速響應型式可選。

派克的二位二通座閥由主級座閥、復位彈簧、先導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)上則允許經節(jié)流的液流自由通過。

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

如果要求反向液流自由通過,則應選擇"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。

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

工作原理:常閉型閥的閥芯由復位彈簧將其壓靠在閥座上,先導液流被關閉,進油口(油口2)的壓力作用在主閥芯內腔,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,將先導閥芯拉離其在主閥芯上的閥座,主閥芯內的壓力泄向油口1,這就使得主閥芯兩端的壓力建立起平衡,于是主閥芯側面的進油壓力將其抬起,允許液流從側面向底部(2至1)流過。

由于該型閥是先導操控的,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)。

常開型閥的先導閥在偏置彈簧的作用下保持開啟狀態(tài),先導液流泄向油口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,推動先導閥芯壓靠在其閥座上,關閉主閥內腔泄向油口1的通道,主閥內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的型式,反向全流量自由流動型式允許油液在底部至側面油口(1至2)的方向上無節(jié)流地自由通過,而快速響應型閥的換向時間在數(shù)豪秒以內。

由于此類閥是先導操控的,閥芯的移動距離較短,這就限制了這類閥的通流能力。

有多種類型的標準電壓和接線端口,以及越權操控選項可供貨,例如:

12VDC

24VDC

120/110VAC,60/50Hz

240/220VAC,60/50Hz

帶引線的導線函

AmpJr.Timer(僅適用于DC電磁線圈)

雙引線(僅適用于DC電磁線圈)

封裝的引線(僅適用于DC電磁線圈)

模塑集成的Deustch接口(僅適用于DC電磁線圈)

此類二位二通座閥的常用市場和應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。
