DDC-JQ电磁真空带充气阀DDC-JQ电磁真空带充气阀概述■DDC-JQ型电磁真空带充气阀是机械真空泵安全阀，安装于机械真空泵的进气口，并与泵同步开启和关闭。当泵停止工作或电源突然中断时，阀门自动关闭。使真空系统保持真空并将大气充入泵腔内，从而避免泵油逆向流动而污染真空系统。适用介质为纯净空气和非腐蚀性气体。■DDC-JQ电磁真空带充气阀Electro-vacuumChargingValve■DDC-JQelectro-vacuumchargingvalveisasafetyvalveforvacuum,pump.Itismountedattheintakenozzleofvacuumpump,synchronouslyopenedandclosedwiththevacuumpump.Incasethatvacuumpumpstopsworkingorpowersupplyissuddenlybrokenoff,valvewillbecosedautomaticallytokeepthevacuumsystemvacuumandtheairchargedintothecavityofvacuumpump,thustopreventpumpoilfromreverseflowthatcanpollutethevacuumsystem.Applicablemediumcanbepureairandnoncorrosivegases.■DDC-JQ电磁真空带充气阀主要技术性能MainTechnicalPerformance■■■适用范围：Applicability105～10-2Pa阀门漏率：ValveLeakRate≤6.7×10-3Pa.L/S.适用温度：Applicability-30～+50℃线围温升：CoilTemperatureRise≤65℃开闭时间：Open-closeTime≤3S电源电压：MainsVoltage220V/50Hz■主要零件材料MaterialsofMainParts■■阀体、阀盖、阀板：碳钢或铝合金密封圈：丁腈橡胶Body,bonnetanddisc:carbonsteeloraluminiumalloySealring:NBRCONSTRUCTIONFIGHTS(mm)■外形及连接尺寸(mm)(JB919)OverallandConnectionDimensions(mm)Model型号DNhBHDDoD1n-dMachinealpump机械泵匹配参考DDC-JQ161628481766842224-M52XZ-0.5～1DDC-JQ252535581998255294-M62XZ-2～4DDC-JQ323240682229264364-M62XZ-4DDC-JQ4040448025311070444-M62XZ-8DDC-JQ5050569429412490554-M82X-15DDC-JQ656565115320135105704-M82X-30DDC-JQ808075140367165125854-M82X-70相关真空阀产品系列：CC超高真空插板阀GDQ气动高真空挡板阀DYC-JQ电磁真空压差阀DDC-JQ电磁真空带充气阀GUD电动真空球阀GU手动真空球阀GUQ气动高真空球阀GI手动高真空蝶阀GIQ气动高真空蝶阀GM高真空隔膜阀CCD电动超高真空插板阀CCQ气动超高真空插板阀)
