VICKERS節(jié)流閥適用于工作壓力zui高為350bar（5000 psi），流量至200l/min（53USgpm） 的場合。和安全閥為一體，組成先導(dǎo)式壓力閥，該閥即是卸荷閥又是安全閥，有時又是溢流閥．卸荷時其控制油道貫穿各路換向閥，同前述卸荷油道．當(dāng)各路換向閥處于中立位置時，卸荷閥的控制油道（見圖1b和圖2）貫穿各路換向閥并與油箱連通．卸荷時，大部分油液卸荷，通道短，壓力損失低．任一路閥換向工作，便切斷控制油道，油源來油就從換向閥進(jìn)入執(zhí)行元件工作，其工作壓力大小由導(dǎo)閥控制．此時系統(tǒng)壓力為導(dǎo)閥調(diào)整壓力．該種卸荷方式，即使換向閥路數(shù)增加，只是控制油道增加，控制壓力精度不高；三級同心結(jié)構(gòu)雖成熟。符合 IP67 等級的環(huán)境保護(hù)。有增強(qiáng)閥功能的選項(xiàng)。概述此樣本中所示的威格士的比例閥設(shè)計成能提供與指令信號成比例的受控的油液流動，有兩種型式可以選擇：*，雙電磁鐵型為執(zhí)行器提供了可逆的流向；第二，單電磁鐵型提供了單方向的流向?？梢赃x用壓力調(diào)節(jié)器用于負(fù)載補(bǔ)償，如果要求增加單磁鐵型的流量，可以選用并行流道模塊，從而使其流量約為標(biāo)準(zhǔn)型閥的兩倍。另外，這兩種閥供貨時可帶有或不帶直接安裝在閥上的內(nèi)裝放大器。標(biāo)準(zhǔn)的直流 24V 電源有很寬的允差帶。閥芯和流量選則范圍廣。標(biāo)準(zhǔn)的直流 ±10V 指令信號。少和簡化了安裝接線。標(biāo)準(zhǔn)的 7 針接頭。維修時閥的拆卸和更換方便。有輔助功能模塊所支持。完備的 CE 電磁相容性。目前應(yīng)用較廣的威格士插裝閥為二級同心式比較，不及二級同心式動作靈敏，規(guī)格相同，行程相同時，二級同心結(jié)構(gòu)的通油能力遠(yuǎn)大于三級同心結(jié)構(gòu)；二級同心式控制壓力穩(wěn)定，加工工藝性好，二級同心式應(yīng)用前景廣闊，這里以二級同心結(jié)構(gòu)，討論其結(jié)構(gòu)尺寸設(shè)計方法．威格士比方向閥設(shè)計成能提供與指令信號成比例的受控的油液流動，并且閥芯位置反饋保證了精確的控制。7型規(guī)格的閥可選用零遮蓋閥芯用于閉 環(huán)控制的場合，還可選用壓力調(diào)節(jié)器用于負(fù)載補(bǔ)償。VICKERS插裝閥和內(nèi)裝放大器作為一個性能經(jīng)過測試的組件來選擇、訂貨和交貨。電氣反饋差動變壓器確保了精確的閥芯位置控制。經(jīng)過振動和沖擊測試。
