进口常闭电磁阀
价格:120.00
美国米勒(MILLER)品牌-进口常闭电磁阀当线圈通电时,先导阀芯吸合,先导孔打开,阀上腔卸压,活塞靠下腔介质压力推动,电磁阀打开;当线圈断电时,先导阀芯靠弹簧复位,先导孔关闭,阀上腔由活塞节流孔增压和复位弹簧的推力,电磁阀关闭。广泛应用在航天、船舶重工、石油化工、给排水、消防设备、食品***设备、清洗设备、景观喷灌、加湿设备、液压设备、测试设备、水厂等,工作压力在0—100MPa的管道系统中。产品特点:阀芯均为不锈钢活塞式,活塞环不会被介质中的杂质卡死,动密封性能高,寿命长;活塞与金属阀腔不产生直接摩擦,阀体安装向无限制;***线圈,不易烧毁;长时间停止动作重新启动,动作同样灵敏;***低启动工作压力0.5MPa。主要技术参数:产品规格:DN0.5~DN200阀体材质:不锈钢适用介质:水、气、油、蒸汽、燃气、腐蚀流体等温度范围:-100~+200℃介质粘度:小于50CSt(大于时需定制)防护性能:防水、防爆(ExdIICT5)、防腐接线方式:接线座式;引线式;插头式控制方式:常开、常闭电源电压:DC12~127V;AC36~380V连接方式:内螺纹、法兰(外螺纹和特殊接口可定做或加转接头)泄漏量:零工作原理:常闭:当线圈通电时,先导阀芯吸合,先导孔打开,阀上腔卸压,活塞靠下腔介质压力推动,电磁阀打开;当线圈断电时,先导阀芯靠弹簧复位,先导孔关闭,阀腔由活塞节流孔增压和复位弹簧的推力,电磁阀关闭。常开:当线圈通电时,先导孔关闭,阀上腔由活塞节流孔增压和复位弹簧的推力,电磁阀关闭。当线圈断电时,先导阀芯靠弹簧复位,先导孔打开,阀上腔卸压,活塞靠下腔介质压力推动,电磁阀打开。注:出口端压力大于进口端压力,介质会反向导通。可安装止回阀或订制自带止回功能的阀。Applicati***:Widelyusedinaerospace,shipbuildingHe***yIndustry,petrochemical,water,firefightingequipment,foodandmedicalequipment,cleaningequipment,landscapeirrigation,humidificationequipment,hydraulicequipment,testingequipment,waterplant,theworkpressureinthepipeline6.4---100MPasystem.Features:Spoolisstainlesssteelpistonandpistonringswillnotbestuckimpuritiesinthemedium,dynamicsealingperformanceandlonglife;pistonvalvechamberwiththemetaldoesnotproducedirectfriction,thevalveinstalledtothelimit;authoritariancoil,easilyburned;foralongtimetorestartthestoppedaction,actionassensitive;minimumstartworkingpressure0.5MPa.Maintechnicalparameters:Specificati***:DN0.5~DN200Bodymaterial:StainlessSteelMedium:Water,gas,oil,steam,gas,corrosivefluidsTemperaturerange:-100~+200℃MediaViscosity:Lessthan50CSt(greaterthanthetimetobecustomized)Protectionperformance:Waterproof,explosion-proof(ExdIICT5),anti-corrosionWiring:TerminalBlockType;leadtype;maleControl:Normallyopen,normallyclosedPowersupplyvoltage:DC12~127V;AC36~380VConnection:Thread,flange(maleandspecialinterfacesoraddcustomadapter)Leakage:ZeroHowitworks:NC:Whenthecoilisenergized,thepilotspoolpullthepilotholetoopen,pressurereliefvalveonthechamber,thepistononthelowerchambermediumpressuretopromote,theelectromagneticvalveisopened;Whenthecoilpower,thepilotvalvebythespringreturn,pilotholeclosedthrottlevalvechamberpressurizedbythepistonreturnspringandthrust,theelectromagneticvalveisclosed.NormallyOpen:Whenthecoilisenergized,thepilotholeclosed,thevalvechamberandpressurizedbythepistonreturnspringthrottlethrust,theelectromagneticvalveisclosed.Whenthecoilpower,thepilotvalvebythespringreturn,pilotholeopen,pressurereliefvalveonthechamber,thepistononthelowerchambermediumpressuretopromotethesolenoidvalveopen.Note:Theoutletpressureisgreaterthantheinletpressure,themediawillpassanti-wizard.Canbeinstalledorcustombuiltnon-returnvalvefunctionofthevalve.电磁阀控制方式选择:常闭型电磁阀指线圈断电时,电磁阀关闭;线圈通电时,电磁阀打开。常开型电磁阀指线圈断电时,深圳名阀电磁阀打开;线圈通电时,电磁阀关闭。我们可以根据持续工作时间长短来选择:常闭、常开、或可持续通电1、当电磁阀需要长时间关闭,并且关闭的时间多于开启的时间应选用常闭型。2、当电磁阀需要长时间开启,并且开启的时间多于关闭的时间应选用常开型。3、需要长时间开启的同时又要长时间关闭时,要选自保持式电磁阀,也叫常开常闭型电磁阀。4、但是有些用于安全保护的工况,如炉、窑火焰监测,则不能选常开的,应选可长期通电型。5、用于燃气警报系统,要选用常开型的燃气紧急切断电磁阀,带手动开启。【订货须知】一、请向我们提供您的使用参数:1.公称通径2、公称压力3、流体性质(包括温度、介质)4.材质5.连接方式6电源.电压7、控制方式(常开式、常闭式、自保持式).8、防护形式(防爆型、防水型、防尘型、防潮型、防腐型、普通型)二、当使用的工况比较重要或管路比较复杂时,请您尽量提供设计图纸和详细参数,由我们***为您审核把关。)
