電磁閥是由電磁線圈和磁芯組成,是包含一個(gè)或幾個(gè)孔的閥體。當(dāng)線圈通電或斷電時(shí),磁芯的運(yùn)轉(zhuǎn)將導(dǎo)致流體通過(guò)閥體或被切斷,以達(dá)到改變流體方向的目的。電磁閥的電磁部件由固定鐵芯、動(dòng)鐵芯、線圈等部件組成;閥體部分由滑閥芯、滑閥套、彈簧底座等組成。電磁線圈被直接安裝在閥體上,閥體被封閉在密封管中,構(gòu)成一個(gè)簡(jiǎn)潔、緊湊的組合。
電磁閥工作性質(zhì):電磁閥一般流通系數(shù)很小,而且工作壓力差很小。比如一般25口徑的電磁閥流通系數(shù)比15口徑的電動(dòng)球閥小很多。電磁閥的驅(qū)動(dòng)是通過(guò)電磁線圈,比較容易被電壓沖擊損壞。相當(dāng)于開關(guān)的作用,就是開和關(guān)2個(gè)作用。
