力士樂比例溢流閥華南現(xiàn)貨

    力士樂比例溢流閥是一種能夠使所輸出油液的參數(shù)（壓力）隨輸入電信參數(shù)（電流或電壓）的變化而成比例地變化的液壓控制閥。通過電磁鐵電壓的變化產(chǎn)生不同大小的推力作用在閥芯上，從而得到連續(xù)變化的液壓壓力。

    力士樂DBE(M)型比例溢流閥又比例先導(dǎo)閥，安全閥和插裝式主閥組成。比例先導(dǎo)閥控制主閥遙控口。力士樂DBE型比例溢流閥按輸入電流大小成比例地控制液壓系統(tǒng)的壓力，閥的通油能力大，適用于流量較大的液壓系統(tǒng)

    力士樂DBE型比例溢流閥的系統(tǒng)壓力限由比例電磁鐵2設(shè)定，與電流有關(guān)，來自系統(tǒng)的壓力作用于主閥芯4，與此同時，經(jīng)過裝有節(jié)流孔5的先導(dǎo)管作用于主閥芯4的彈簧加載側(cè)并作用在先導(dǎo)閥芯6.如果系統(tǒng)壓力升高得超過對應(yīng)著電磁鐵力的設(shè)定值，則先導(dǎo)閥芯6打開。現(xiàn)在先導(dǎo)油可以流回油箱，節(jié)流孔組產(chǎn)生作用在主閥芯4上的壓降，使它從閥座上升起并打開從泵到油箱的通路。
    力士樂DBEM行比例溢流閥為了保護系統(tǒng)免遭比例電磁鐵2不能允許的高電流尖峰引起的不能允許的高壓之害，有一種供選方案是裝設(shè)一個彈簧加載的壓力溢流閥7zui高保護。

    力士樂DBE(M)型比例溢流閥由直流比例電磁鐵和先導(dǎo)型溢流閥組成。工作原理是：當(dāng)輸入一個電信時，比例電磁鐵1便產(chǎn)生一個相應(yīng)的電磁力，它通過推桿2和彈簧3的作用，使錐閥4接觸在閥座5上，因此打開的液壓力與電流成正比，形成一個比例先導(dǎo)壓力閥。孔a為主閥閥芯6的阻尼孔，由先導(dǎo)式溢流閥工作原理，對溢流閥閥芯6上的受力分析可知，電液比例溢流閥壓力的高低與輸人信電流的大小成正比，即油壓受輸入電磁鐵的電流大小控制。若輸入信電流是連續(xù)地按比例地或按一定程序變化，則比例溢流閥所調(diào)節(jié)的液壓系統(tǒng)壓力，也連續(xù)地按比例地或按一定程序地進行變化。從而將手調(diào)溢流閥，改為電信控制。

　　力士樂DBE(M)型比例溢流閥實現(xiàn)多級壓力控制，當(dāng)以不同電流J1、j2、J3、J4和J5輸入時，溢流閥就可得到五種壓力控制，它與普通溢流閥的多級壓力控制相比，液壓元件數(shù)量少，系統(tǒng)簡單。若輸入的是連續(xù)變化的信則可實現(xiàn)連續(xù)的壓力控制。

　　先導(dǎo)型比例溢流閥。它的先導(dǎo)部分是直動式比例壓力閥，可作為直動式比例溢流閥使用。若與普通壓力閥組合，可組成先導(dǎo)型比例溢流閥、比例減壓閥和比例順序閥等元件。
