科恩科KNKE電磁真空帶充氣閥，Electromagnetic vacuum charging valve，是安裝在機(jī)械式真空泵上的專用閥門。閥門與泵接在同一電源上，泵的開啟與停止直接控制了閥的開啟與關(guān)閉。當(dāng)泵停止工作或電源突然中斷時(shí)，閥能自動(dòng)將真空系統(tǒng)封閉，并將大氣通過泵的進(jìn)氣口充入泵腔，避免泵油返流污染真空系統(tǒng)。
適用的工作介質(zhì)為空氣及非腐蝕性氣體。 

electro-vacuum charging valve is a safety valve for vacuum, pump. It is mounted at the intake nozzle of vacuum pump, synchronously opened and closed with the vacuum pump. In case that vacuum pump stops working or power supply is suddenly broken off, valve will be cosed automatically to keep the vacuum system vacuum and the air charged into the cavity of vacuum pump, thus to prevent pump oil from reverse flow that can pollute the vacuum system. Applicable medium can be pure air and noncorrosive gases.
