DDC-JQ電磁真空帶充氣閥

DDC-JQ型電磁真空帶充氣閥是機(jī)械真空泵安全閥,安裝于機(jī)械真空泵的進(jìn)氣口,并與泵同步開(kāi)啟和關(guān)閉。當(dāng)泵停止工作或電源突然中斷時(shí),閥門自動(dòng)關(guān)閉。使真空系統(tǒng)保持真空并將大氣充入泵腔內(nèi),從而避免泵油逆向流動(dòng)而污染真空系統(tǒng)。適用介質(zhì)為純凈空氣和非腐蝕性氣體。

DDC-JQ電磁真空帶充氣閥概述

Overview of DDC-JQ electromagnetic vacuum belt charging valve

DDC-JQ型電磁真空帶充氣閥是機(jī)械真空泵安全閥,安裝于機(jī)械真空泵的進(jìn)氣口,并與泵同步開(kāi)啟和關(guān)閉。當(dāng)泵停止工作或電源突然中斷時(shí),閥門自動(dòng)關(guān)閉。使真空系統(tǒng)保持真空并將大氣充入泵腔內(nèi),從而避免泵油逆向流動(dòng)而污染真空系統(tǒng)。適用介質(zhì)為純凈空氣和非腐蝕性氣體。

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.
