DDC-JQ型電磁真空充氣閥是安裝在機械式真空泵上的專用閥門，適用介質為純凈空氣和非腐蝕性氣體，與泵同步開啟和關閉，保護機械真空泵的安全。介紹電磁真空充氣閥的型號規格、工作原理、技術參數、結構、外形尺寸。
高真空電磁閥
工作原理
電磁真空充氣閥安裝于機械真空泵的進氣口，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閉。當泵停止工作或電源中斷時，閥能自動將真空系統封閉，并將閥的充氣孔打開，大氣快速充入到泵腔，從而避免泵油逆流污染真空系統。

Electro-vacuum Charging Valve
DDC-JQ 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.主要技術性能
