进口真空隔膜阀Orsen型－高真空隔膜阀真空隔膜阀是利用阀杆将橡胶膜直接压在阀座上，用来截止或接通真空系统。采用连接形式有活套法兰连接、快卸法兰连接、焊接式连接。焊接式连接又分焊接式I型连接〔即两端焊接〕，焊接式II型连接〔即一端焊接，另一端插入〕。阀门适用的工作介质为空气及非腐蚀性气体。进口真空隔膜阀是在阀体和阀盖内装有一挠性隔膜或组合隔膜，其关闭件是与隔膜相连接的一种压缩装置。阀座可以是堰形，也可以是直通流道的管壁。隔膜阀的优点是其操纵机构与介质通路隔开，不但保证了工作介质的纯净，同时也防止管路中介质冲击操纵机构工作部件的可能性。此外，阀杆处不需要采用任何形式的单独密封，除非在控制***介质中作为安全设施使用。它的工作温度范围大约为－50～175℃。隔膜阀结构简单，只由阀体、膜片和阀头组合件三个主要部件构成。该阀易于快速拆卸和维修，更换隔膜可以在现场及短时间内完成。Vacuumdiaphragmistheuseofstemrubbermembranepresseddirectlyontheseat,ortoturnoffthevacuumsystem.Usingconnecti***intheformoflooseflangeconnection,quickreleaseflangeconnection,weldedconnection.WeldedconnectionisdividedweldedI-typeconnectorsatbothends[ie]welding,weldedconnectiontypeII[ieweldingendandtheotherendinto].Valvesuitableworkingmediumforairandnon-corrosivegases.Importedvacuumdiaphragmvalvebodyandbonnetarebuiltwithaflexiblediaphragmoracombinationofthediaphragm,theclosurememberisacompressiondeviceconnectedtothediaphragm.Theseatcanbeshapedweir,theflowchannelmaybeastraightwall.Advantagesdiaphragmisseparatedfromitsoperatingmechani***andmediaaccess,notonlytoensurethepurityoftheworkingmedium,butalsopreventthepossibilityoftheimpactofthepipelinetomanipulatethemediaagencyworkingparts.Inaddition,stemDepartmentdoesnotrequireanyformofindividuallysealed,unlessinthecontrolofharmfulusemediaasasecurityfacility.Itsoperatingtemperaturerangeofabout-50~175℃.Simplediaphragmstructurec***istsonlyofthebody,diaphragmandvalveheadassemblyofthreemaincomponents.Thevalveiseasytoquicklydisassembleandrepair,replacementofthediaphragmcanbedoneon-siteandinashorttime.■Orsen型高真空(压力)隔膜阀用于接通或切断真空(压力)系统管路中的介质流。应用于真空、乳制品、酒业、生物工程、食品、制药、饮料、化妆品及化工领域。HighVacuum(Pressure)DiaphragmValve■Orsenhighvacuum(pressure)diaphragmvalveisusedtoputthroughorcutoffthemediumflowinvacuum(pressure)pipelineintheareasofvacuum,dairyproducts,breweries,biologicalengineering,foodstuff,pharmaceuticals,drinks,co***eticsandchemicals.■主要技术性能MainTechnicalPerformance■阀门漏率：ValveLeakRate≤1.3×10-4Pa.L/S.适用温度：ApplicableTemperature-30～+150℃(氟橡胶)适用范围：Applicability连接型式LooseFlange使用压力范围(Pa)活套法兰(GB6070、JB919)0.6×106～1.3×10-4焊接法兰(GB6070、JB919)1.6×106～1.3×10-4快卸法兰(GB4982)0.1×106～1.3×10-4螺纹连接ThreadedConnection1.6×106～1.3×10-4德国ORSEN奥尔申进口真空球阀以独特的设计特点、精湛的制造工艺和近乎***的运行可靠性已在全世界60多个***和地区赢得了市场与声誉。产品质量通过了德国燃气与供水工程联合会、SVTW瑞士燃气与供水工程联合会、KIJH奥地利燃气与供水工程联合会、LIKJ德国技术检测***会、Lloyd’s等。GermanyORSENOrrShenimportedvacuumvalvewithuniquedesignfeatures,superbworkmanshipandnear-perfectreliabilityhasearnedareputationintheworldmarketwithmorethan60countriesandregi***.ProductqualitybytheGermanGasandWaterWorksAssociation,SVTWSwissGasandWaterWorksAssociation,KIJHAustrianFederationofgasandwatersupplyprojects,LIKJGermandetectCommittee,Lloyd'sandsoon.Forinformation,pleaseaccessimportedvacuumvalve(http://www.bj-)theURL.Forthepriceofimportedelectricvacuumvalve,pleasecall(Contact:WangShuo010-80842199Fax:010-80842199)thecall.)
