寶德5281型伺服輔助電磁閥,BURKERT伺服輔助電磁閥
寶德5281型伺服輔助電磁閥是由濕式閥用電磁鐵，閥芯，傳動柱塞，閥套，頂針桿，鋼球，鋼球座，復位彈簧等組成。閥芯與閥體為螺紋聯(lián)接。傳動柱塞一端連接電磁鐵銜鐵，另一端頂住鋼球。因此無論是上端電磁鐵的推力還是下端彈簧的作用力都使兩鋼球與頂針桿成連動關系。頂針桿兩端與閥芯之間各有一段環(huán)形控制容腔，并分別與閥芯上的徑向孔道連通。這是一種二位三通雙球常閉式電磁閥。當電磁鐵斷電時，從P腔進入的壓力油直接作用在導閥的球座上，而復位彈簧的彈性力也同向作用在球座上，使導閥下閥口關閉，上閥口打開，因而使壓力油路與控制油路A阻斷，控制油路與回油路T開通。寶德5281型伺服輔助電磁閥采用一次開閥和二次開閥連在一體，主閥和導閥分步使電磁力和壓差直接開啟主閥口。當線圈通電時，產生電磁力使動鐵芯和靜鐵芯吸合，導閥口開啟而導閥口設在主閥口上，且動鐵芯與主閥芯連在一起，此時主閥上腔的壓力通過導閥口卸荷.
