进口真空不锈钢球阀
价格:999.00
进口真空球阀德国进口真空(压力)球阀是适用于真空(是指工作压力低于标准大气压的,形成一定真空的气体)系统中接通或切断管路的介质流。该阀为直通式手动球阀,靠球面密封,因而既能用在真空状态下,也能在低压状态下使用,并可任意位置安装。适用的工作介质真空气体。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。Germanyimportedvacuum(pressure)isappliedtothevacuumvalve(refertotheworkingpressureislowerthanthestandardatmosphericpressure,acertainvacuumgas)systemisturnedonoroffmediumflowpipeline.Themanualballvalveforstraight-through,bysphericalseal,whichcannotonlybeusedinavacuum,canbeusedatlowpressure,andcanbeinstalledanywhere.Suitableworkingmediumvacuumgas.Vacuumisapplied,dairyproducts,wine,biologicalengineering,food,pharmaceutical,beverages,co***eticsandchemicalindustries.进口真空球阀连接形式:法兰连接可分为以下几种:1)光滑式:用于压力不高的阀门。加工比较方便2)凹凸式:工作压力较高,可使用中硬垫圈3)榫槽式:可用塑性变形较大的垫圈,在腐蚀性介质中使用较广泛,密封效果较好。4)梯形槽式:用椭圆形金属环作垫圈,使用于工作压力≥64公斤/平方厘米的阀门,或高温阀门。5)透镜式:垫圈是透镜形状,用金属制作。用于工作压力≥100公斤/平方厘米的高压阀门,或高温阀门。6)O形圈式:这是一种较新的法兰连接形式,它是随着各种橡胶O形圈的出现,而发展起来的,它在密封效果上比一般平垫圈可靠。Importedvacuumvalveconnection:Flangeconnecti***canbedividedintothefollowingcategories:1)***oothformula:valvesforpressureisnothigh.Processingmoreconvenient2)lenticular:higherworkingpressure,canbeusedinhardwasher3)tenonslot:***ailableplasticdeformationlargerwashers,useincorrosivemediaismoreextensiveandbetterseal.4)trapezoidaltrough:ovalmetalring,gasket,theuseofworkingpressure≥64kg/cmofthevalve,orhightemperaturevalves.5)Lenstype:washerlensshape,madeofmetal.Forworkingpressure≥100kg/cmhighpressurevalves,orhightemperaturevalves.6)O-ringstyle:Thisisarelativelynewformofflangeconnection,itiswiththeemergenceofavarietyofrubberO-ring,anddeveloped,itisgenerallyflatwashersreliablesealingeffectontheratio.螺纹连接又可分为以下几种:这是一种简便的连接方法,常用于小阀门。又分两种情况:1)直接密封:内外螺纹直接起密封作用。为了确保连接处不漏,往往用铅油、线麻和聚四氟乙烯生料带填充;其中聚四氟乙烯生料带,使用日见广泛;这种材料耐腐蚀性能很好,密封效果***,使用和保存方便,拆卸时,可以完整地将其取下,因为它是一层无粘性的薄膜,比铅油、线麻优越得多。2)间接密封:螺纹旋紧的力量,传递给两平面间的垫圈,让垫圈起密封作用。进口真空球阀参数:阀门漏率:ValveLeakRate≤1.3×10-4Pa.L/S.适用温度:ApplicableTemperature-30~+150℃-30~+150℃(PPL密封)适用范围:AppyRange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ThreadedConnection1.6×106~1.3×10-4Threadedconnectioncanbedividedintothefollowingcategories:Thisisasimpleconnectionmethod,commonlyusedin***allvalve.Wasdividedintotwocases:1)DirectSeal:internalandexternalthreaddirectlyfromtheseal.Toensurethattheconnectiondoesnotleak,oftenwithleadoil,hempandTeflontapefilled;whichTeflontape,hasbecomeincreasinglywidespreaduse;thismaterialgoodcorrosionresistance,sealingeffectpolegood,easytouseandpreservation,demolition,youcancompletelyremoveit,becauseitisalayerofnon-tackyfilm,hempoilismuchsuperiortotheleadline.2)IndirectSeal:Threadtightenforcetran***ittedtothegasketbetweentwoplanes,sothatthegasketfromsealing.Importedvacuumvalveparameters:??Valveleakrate:ValveLeakRate≤1.3×10-4Pa.L/S.Temperature:ApplicableTemperature-30~+150℃-30~+150℃(PPLsealed)Scope:AppyRangeTypeofconnectionLooseFlangepressurerange(Pa)Looperflange(GB6070,JB919)0.6×106~1.3×10-4Weldingflange(GB6070,JB919)1.6×106~1.3×10-4Quickreleaseflange(GB4982)0.1×106~1.3×10-4ThreadedThreadedConnection1.6×106~1.3×10-4进口真空球阀特点:1、可在高真空状态下使用,也可在低压的系统下使用,达到正负压同用的优点。2、不仅结构简单、密封性好、而且安装尺寸小,驱动力矩小,操作简单,易实现快速启闭Importedvacuumvalvefeatures:1,canbeusedinahighvacuum,mayalsobeusedinlow-pressuresystemtoachievetheadvantageswiththeuseofpositiveandnegativepressure.2,isnotonlysimplestructure,goodsealing,andtheinstallationof***allsize,***alldrivetorque,simpleoperation,easyopenandclosefast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.)
