進口電磁真空壓差閥
德國沃德WODE的WDYC-JQ型－電磁真空壓差閥
WDYC-JQ型電磁真空壓差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閉。當泵停止工作或電源突然中斷時，閥門利用大氣壓力使閥板自動關閉，使真空系統保持真空并將大氣充入泵腔內，從而避免泵油逆向流動而污染真空系統。適用介質為純凈空氣和非腐蝕性氣體。
WDYC-JQ Electro-vacuum DifferentialPressure Valve
WDYC-JQ electro-vacuum differentialPressure valve is a safely valve for mechanical vacuum pump. It is mounted atthe intake nozzle of mechanical vacuum pump, synchronously opened and closedwith the pump. In case that pump stops working or power supply is suddenlybroken off, valve disc will be closed automatically under atmospheric pressure,to keep the vacuum system vacuum and the air charged into pump cavity, thus toprevent pump oil from reverse flow that can pollute the vacuum system.Applicable medium can be pure air or noncorrosive gases.
