DDC-JQ電磁（cí）真空帶（dài）充氣閥概述（shù）
DDC-JQ電磁真空帶充氣閥是機械真空泵安全閥，安裝於機械真空泵的進氣口，並與泵同步開（kāi）啟（qǐ）和關閉。當泵停止工作或（huò）電源（yuán）突然中斷時，閥（fá）門（mén）自動關閉。使真空係統保持真空並將大氣充入泵腔內，從而（ér）避免（miǎn）泵油逆向流動而汙染真空係統。適用介質為純淨（jìng）空（kōng）氣和非腐蝕性氣體。
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.
