进口气动真空蝶阀所属类别：真空阀全称：Orsen型-气动高真空蝶阀气动真空蝶阀的主要优点，结构简单，体积小重量轻，造价低，气动蝶阀该特点尤其显著，安装在高真空管道。流体阻力较小，中大口径的气动蝶阀全开时有效流通面积较大，启闭迅速省力，碟扳旋转90角度即可完成启闭，由于转轴两侧蝶板手介质作用力接近相等，而产生的转矩方向相反，因而启闭力矩较小，低压下可实现良好的密封，蝶阀密封材料有丁晴橡胶、氟橡胶，食用橡胶，衬四氟故密封性能良好，其中硬密封蝶阀为软硬层叠式金属片具有金属硬密封和弹性密封的重优点，无论在低温情况下均具有优良的密封性能。Themainadvantageofthevacuumpneumaticbutterflyvalve,simplestructure,***allsize,lightweight,lowcost,pneumaticbutterflyThisfeaturewasparticularlynotable,installedinahighvacuumline.Fluidresistanceis***all,whilethelarge-diameterpneumaticvalvefullyopenandeffectiveflowoflarger,openandcloserapidlyeffort,pullthediscrotationangleof90tocompletetheopeningandclosing,duetothemediaonbothsidesoftheshaftbutterflywrenchforcenearlyequal,andthetorquegeneratedbytheoppositedirection,sothe***alleropeningandclosingtorque,lowpressurecanachieveagoodseal,valvesealmaterialsNBR,Viton,ediblerubber,PTFEliningsogoodsealingperformance,whichisasoftsealbutterflyadvantageshardhe***ymetalsheetsstackedwithametalsealandaresilientseal,bothatlowtemperaturesh***eexcellentsealingproperties.进口气动真空特点：1、小巧轻便，容易拆装及维修，并可在任意位置安装。2、结构简单、紧凑，操作扭矩小，90°回转开启迅速。3、流量特性趋直线，调节性能好。4、蝶板与阀杆的连接采用无销钉结构，克服了有可能的内泄漏点。5、蝶板外圆采用球面造型，提高了密封性能及延长了阀门的使用寿命，带压启闭5万次以上仍保持零泄漏。6、密封件可更换，且密封可靠达到双向密封。7、蝶板可根据用户要求喷涂覆层，如尼龙或聚四氟类。8、该阀可设计成法兰连接和对夹连接。9、驱动方式可选择手动、电动或气动。Importedpneumaticvacuumfeatures:1,***all,lightweight,easyinstallationandmaintenance,andcanbemountedinanyposition.2,thestructureissimple,compact,lowoperatingtorque,90°swingopenquickly.3,theflowcharacteristicsoflineartrend,regulatedperformance.4,thedisc-freeconnectionwiththestempinstructure,itispossibletoovercometheinternalleaks.5,usingthesphericalshapeoftheouterdisc,improvedsealingperformanceandextendthelifeofthevalve,withpressurehoistmorethan50,000timesremainzeroleakage.6,thesealscanbereplaced,andachievebi-directionalsealingreliablesealing.7,thedisccanbesprayedcoatingsbasedonuserrequirements,suchasnylonorPTFEclasses.8,thevalvecanbedesignedintoflangedandwafer.9,driveoptionalmanual,electricorpneumatic.■Orsen型－气动高真空蝶阀■Orsen型气动高真空蝶阀是通过电磁换向阀改变气路方向，控制执***缸驱动蝶阀作启闭运动。用于接通或切断真空管路中的气流。适用介质为纯净空气和非腐蚀性气体。可选配反馈信号装置及电气阀门***器。■OrsenPneumaticHighVacuumButterflyValve■Orsenpneumatichighvacuumbutterflyvalveusessolenoiddirectionalvalvetochangethedirectionofairpassage,andcontrolstheactuatingcylindertodrivethebutterflyvalveopenedandclosed.Itisusedtoputthroughorcutofftheairflowinvacuumpileline.Applicablemediumcanbepureairandnoncorrosivegases.Theymaybefittedwithsignalfeedbackdeviceandelectropneumaticvalvepositioner.气动真空蝶阀参数：适用范围：Applicability105～1.3×10-4Pa阀门漏率：ValveLeakRate≤1.3×10-4Pa.L/S.适用温度：ApplicableTemperature-30～+150℃(氟橡胶)气源压力：MainsVoltage0.4～0.6MPa安装方向：MountingDirection任意德国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.Forthepriceofimportedvacuumvalve,pleasecall(Contact:WangShuo010-80842199Fax:010-80842199thecall.)
