詳細(xì)介紹
atos阿托斯意大利品牌,是世界的電液元件制造商,具有*的技術(shù),能通過帶電子器件的集成式液壓元件提高現(xiàn)代化機(jī)器的性能。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。這個電磁閥實際上由兩部分組成: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動來實現(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,(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。產(chǎn)品型號有:AGAM-20/11/210-IX 230/50/60AC

溢流閥一般分為兩類:1、直動型溢流閥 。2、先導(dǎo)型溢流閥,在實際應(yīng)用中為:作卸荷閥用,作遠(yuǎn)程調(diào)壓閥,作高低壓多級控制閥,作順序閥,用于產(chǎn)生背壓。
