德國力士樂電磁閥4WE6J6X/EW230N9DL現貨                                                                            德國力士樂Rexroth泵、閥、馬達全系列                                                                                        德國力士樂電磁換向閥的分類
　　電磁換向閥的品種繁多，按其工作位置數和通路數的多少可分為二位三通、二位四通、三位四通等；按其復位和定位形式可分為彈簧復位式、鋼球定位式、無復位彈簧式；按其閥體與電磁鐵的連接形式可分為法蘭連接和螺紋連接；按其所配電磁鐵的結構形式可分為干式和濕式，每一類又有交流、直流、本整等形式，而且所需電源電壓又有好多種，因而在其結構上存在很多差別。 1.按接口數及切換位置數分類 　　接口是指閥上各種接油管的進、出口，進油口通常標為P，回油口則標為R或T，出油口則以A、B來表示。閥內閥芯可移動的位置數稱為切換位置數,通常我們將接口稱為“通”，將閥芯的位置稱為“位”。因此，按其工作位置數和通路數的多少可分為二位三通、二位四通、三位四通等。位和通路符號
2.按操作方式分類 　　推動閥內閥芯移動的動力有手、腳、機械、液壓、電磁等方法。 3.按其復位和定位形式分類 　　可分為彈簧復位式、鋼球定位式、無復位彈簧式。 4.按其閥體與電磁鐵的連接形式分類 　　可分為法蘭連接和螺紋連接。 5.按其所配電磁鐵的結構形式分類 　　可分為干式和濕式。 R900558642 4WE6G6X/EW110N9K4
