進口電磁真空帶充氣閥

德國沃德WODE的進口WDC-JQ型－電磁真空帶充氣閥

WDC-JQ型電磁真空帶充氣閥是機械真空泵安全閥，安裝于機械真空泵的進氣口，并與泵同步開啟和關(guān)閉。當泵停止工作或電源突然中斷時，閥門自動關(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。

WDC-JQ-Electro-vacuum Charging Valve

WDC-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.
