DYC-JQ电磁真空压差阀DYC-JQ电磁真空压差阀概述■DYC-JQ型电磁真空压差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，阀门利用大气压力使阀板自动关闭，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。■DYC-JQElectro-vacuumDifferentialPressureValve■DYC-JQelectro-vacuumdifferentialPressurevalveisasafelyvalveformechanicalvacuumpump.Itismountedattheintakenozzleofmechanicalvacuumpump,synchronouslyopenedandclosedwiththepump.Incasethatpumpstopsworkingorpowersupplyissuddenlybrokenoff,valvediscwillbeclosedautomaticallyunderatmosphericpressure,tokeepthevacuumsystemvacuumandtheairchargedintopumpcavity,thustopreventpumpoilfromreverseflowthatcanpollutethevacuumsystem.Applicablemediumcanbepureairornoncorrosivegases.■DYC-JQ型电磁真空压差阀主要技术性能MainTechnicalPerformance■■■适用范围：Applicability105～10-2Pa阀门漏率：ValveLeakRate≤1.3×10-2Pa.L/S.适用温度：ApplicableTemperature-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：碳钢或铝合金隔膜：丁腈橡胶加涤纶绸Body,bonnetanddisc:carbonsteeloraluminiumalloyDiaphragm:NBRandterylenesilkCONSTRUCTIONFIGHTS(mm)■外形及连接尺寸(mm)OverallandConnectionDimensions(mm)■活套法兰连接(GB6070图一)Model型号DNDoDD2n-φcAHDYC-JQ505090110554-φ970203DYC-JQ6363105130684-φ988226DYC-JQ8080125145858-φ998260DYC-JQ1001001451651058-φ9108282DYC-JQ1601602002251658-φ12158350■快卸法兰连接(GB4982图二)Model型号DND1DAHBDYC-JQ161617.2304016055DYC-JQ252526.2405017060DYC-JQ323234.2555817960DYC-JQ404041.2556518770DYC-JQ505052.2757020385■方体螺纹连接(JB919图三)Model型号DNDoD2hBHn-dDYC-JQ1616422228481484-M5DYC-JQ2525552935581554-M6DYC-JQ3232643640681604-M6DYC-JQ4040704444801664-M6DYC-JQ5050905556941894-M8DYC-JQ656510570651152054-M8DYC-JQ808012585751402504-M8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)
