賀德克電磁溢流閥PDR08-50-C-N-030-24PG溢流閥一般有兩種結(jié)構(gòu)：1、直動型溢流閥 。2、先導(dǎo)式溢流閥。
對溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。
1）電磁溢流閥原理上，一般是由先導(dǎo)式溢流閥加上一個2位2通電磁閥組成。
2）這個電磁閥實(shí)際上由兩部分組成：2位2通的液壓閥部分，加上一個電磁鐵。2位2通閥是開通，還是關(guān)閉，是由電磁鐵推動閥芯運(yùn)動來實(shí)現(xiàn)的。像樓上朋友講的，有的閥電磁鐵通電時打開，有的閥電磁鐵斷電時打開，蘿目青菜個人各愛（根據(jù)系統(tǒng)要求選擇）。也就是說，電磁閥這里有一條通路一頭與先導(dǎo)溢流閥的某個部位相連，另一頭通過油管與油箱相連。通過操作電磁鐵可以讓先導(dǎo)溢流閥的某個部位或者與油箱相通，或者不與油箱相通。3129360;PDB10P-01M-C-N-330-12PG-2.2;286

賀德克比例減壓閥PDM08130-01X-25-G24-Z4;344 屬高壓閥系列，適用于冶金、石油、液壓、水壓試驗(yàn)機(jī)組上。主要用途:是采用節(jié)流耗能達(dá)到降壓的功能，能使高壓、超高壓設(shè)備和高壓管道內(nèi)的高壓水通過此閥將高壓水降至低壓所需壓力后排出，使高壓系統(tǒng)壓力均勻降低。
工作原理
導(dǎo)閥的開啟都是利用頂部的調(diào)節(jié)螺栓順時針方向擰動，使彈簧縮產(chǎn)生的彈力，使導(dǎo)閥膜片向下凹陷，作用在導(dǎo)閥連桿上的力，使之向下位移打開導(dǎo)閥。當(dāng)導(dǎo)閥開啟后，上游進(jìn)汽管段A腔的蒸汽通過α通道(供汽調(diào)節(jié)通道)，經(jīng)過導(dǎo)閥進(jìn)入導(dǎo)閥環(huán)形汽腔，由β通道直接送到下面的活塞汽缸上腔。在A腔蒸汽不斷的供給下，壓力持續(xù)升高，推動活塞下行打開主閥，這時蒸汽源源不斷從A腔流至B腔。當(dāng)下游出口管段B腔負(fù)荷滿足的情況下，余多的蒸汽又使B腔內(nèi)的壓力不斷升高。不斷升高的壓力通過γ通道(壓力感應(yīng)通道)反饋到導(dǎo)閥膜片下腔，使導(dǎo)閥膜片向上突起，克服了上部調(diào)節(jié)彈簧的壓力，導(dǎo)閥被關(guān)小或關(guān)閉。從而，關(guān)小或關(guān)閉來自上游α通道的蒸汽源。當(dāng)活塞汽缸上腔壓力下降時，在下面復(fù)位彈簧的作用下，主閥被關(guān)小或關(guān)閉，這時B腔內(nèi)的壓力開始下降，這樣周而復(fù)始達(dá)到調(diào)壓的目的。3115602;WKM08130C-01-C-N-24DG
