产品介绍：利用高精度研磨不锈钢空心浮球在阀腔内随着凝结水的液位变化开启或关闭阀门。该疏水阀的结构比较简单，主要由浮球和自动排空装置组成。阀腔内***的动作元件——不锈钢空心浮球，采用高精度研磨工艺制造，整个球面均可做密封面，工作时无集中磨损，使用寿命长;阀腔内无易损件，可靠性高。浮球能根据水位变化而自由调节阀孔的开度，能够连续排放凝结水，过冷度≈0℃，工作效率高。自动排空装置分为两种:（低压PN25以内）液囊热敏元件组成和（过热蒸汽系统）双金属片组成。Free-ballfloattrapThedrainvalveisopenedorclosedbytakingadvantageofthechangeofliquidlevelofcondensatewaterwiththehigh-precisiongrindingstainlesssteelhollowfloatballinthevalvec***ity.Thissteamtraphasasimplestructure,mainlyc***istingoffloatballsandautomaticemptyingdevices.Thesoleactionelements,namely,thestainlesssteelhollowfloatballismanufacturedbyhigh-precisiongrindingprocess,anditsentirespherecanserveasthesealingfaceandwillnotbewornintensivelyduringthework,soithasalongerservicelife.Inaddition,thereisnowearingpartinthevalvec***ity,withahighreliability.Thefloatballcanfreelyadjusttheopennessofthevalveopeninginresp***etothechangeofwaterlevelanddischargethecondensatewatercontinuouslywithasubcooledtemperatureofabout0℃andhigherefficiency.Theautomaticemptyingdevicesfallintotwotypes:(withinlowpressurePN25)c***istingofreservoirthermo-sensitiveelementsand(overheatedsteamsystem)c***istingofbimetals.优点：1、***转动的是高精度研磨的不锈钢浮球，抗腐蚀。2、结构简单，维修方便。3、不受压力波动的影响，连续排水，噪声小。4、装有自动排空装置，能够迅速排除空气，防止气堵和汽锁。5、体积小，排量大。6、有水就排，能够加快系统启动速度。Merits1.Thesolemovingcomponentisthehigh-precisiongrindingstainlessfloatball,whichcanresisterosion.2.Itssimplestructureisconvenientformaintenance.3.Todraincontinuouslywithlownoise,withoutbeingaffectedbythefluctuationofthepressure.4.Tobeequippedwithautomaticemptyingdevicesanditcaneliminateairquicklyandpreventairblockingandsteamlocking.5.***allvolumeandlargedisplacement.6.Todrainwheneverthereiswaterleftoversoastoquickenthestartupspeedofthesystem.主要零件材料/Thematerialsofprimaryaccessories零部件名称Partandcomponentname材质Material阀体、阀盖Valvebody、valvecover铸铁、铸钢、不锈钢Castiron、Caststeel、Stainlesssteel自由浮球Freefloatball304/316不锈钢304/316Stainlesssteel阀座Valveseat高铬不锈钢Highchromestainlesssteel自动排空气装置Automaticairexhaust不锈钢、热敏元件Stainlesssteel、Thermo-sensitiveelement过滤网、罩Filtratingscreen、Cover不锈钢Stainlesssteel不锈钢球直径/Diameterofstainlessbal材质/MaterialB,JH5ND,JH7NE,JH9NF,JH11NG,JH13N铸铁Castiron68110150180200铸钢Caststeel70120150190220工作原理说明：在设备刚启动时，低温冷凝水和空气同时进入阀腔，这时开启自动排空装置将空气排除，使低温凝结水顺利进入阀腔，阀腔内的凝结水的液位随即上升，使浮球升高，开启阀孔，将凝结水迅速排出;前面的蒸汽很快进入加热设备，使设备迅速加热升温，当蒸汽或较高温度的凝结水进入阀腔时，自动排空装置开始膨胀，关闭自动排空气装置，疏水阀开始正常工作。这时阀腔内的浮球随凝结水液位的高低而升降，能连续的排放凝结水。由于自由浮球式疏水阀的阀座孔总处于凝结水液位以下，形成水封，水汽自然分离，工作时达到无蒸汽泄漏。该阀的***小工作压力为0.01Mpa，从0.01Mpa至***高工作压力范围内不受温度和工作压力波动的影响，能连续工作，其***小过冷度约为0℃，由于该阀能自动、连续地排除凝结水，加热设备内不会有水积聚，能使加热设备达到***佳换热效率。是生产工艺加热设备的***理想疏水阀之一。DescriptionofworkprincipleBothlow-temperaturecondensedwaterandairwillrunintothevalvec***itywhentheequipmentisjuststarted,c***equently,automaticairdischargeequipmentwillbeopenanddischargetheair,enablinglow-temperaturecondensedwatercomingintothevalvec***ity***oothly,atthemoment,theleveloflow-temperaturecondensedwaterinsidewillriseswiftly,whichbringaboutelevationofballfloatingandopenofvalvehole,forthepurposeofdischargingthecondensedwater;thesteamearlierwillenterintoheatingequipmentsoon,whichh***eequipmentheatingandpromotingtemperatureinafastmanner,theautomaticairdischargeequipmentwillstartinflatingasthesteamorratherhigh-temperaturecondensedwaterenterintovalvec***ity,otherwise,trapshouldoperatenormallyassoonastheautomaticairdischargeequipmentisclosed.Atthemoment,theballfloatinginsidevalvec***itywillupanddownalongwiththelevelofthecondensedwater,andwithcapabilityofcontinuouslydischargingcondensedwater.Duetothefactthatthevalveseatholeoffree-ballfloattrapisalwaysbelowthelevelofcondensedwater,ultimatelyformedwatersealthatseparatedwaterandsteaminanaturalway,therefore,thereshouldbeinnocircumstanceofleakageofsteamduringoperationoftheequipment.Thevalvewillbeartheminimumworkpressureof0.01Mpa,inaddition,itwillkeepoperatingcontinuouslywithoutinfluenceoftemperatureandfluctuationofworkpressurewithinthescopebetween0.01Mpaandmaximumworkpressure.Inc***iderationoftheminimumsupercoolingdegreeofthevalveisabout0℃,coupledwiththefactthatthevalveiscapableofdischargingcondensedwaterautomaticallyandcontinuously,therefore,heatingequipmentwillremainabsenceofaccumulatedwater,whichcouldh***eheatingequipmentreachoptimumefficiencyinheatexchange.Allinall,thevalveisoneofthebesttrapsforheatingequipmentapplicabletoproduction.自由浮球式疏水阀FREE-BALLFLOATTRAP技术参数/Techniqueparameter壳体压力等级Shellpressuregrade负荷泄漏率Loadleakagerate使用介质Usedmedium壳体材质Shellmaterial允许背压率Permittedbackpressurerate***大工作压差Maximumoperatingpressuredifferential1.6、2.5、4.0、6.4MPA≈0%蒸汽、凝结水Steam、Condensatewater碳钢/304/316Carbonsteel≥80%4.0MPA节能效果Energys***ingeffect***小过冷度Minimumsubcooledtemperature排水方式Drainagemethod***高允许温度Maximumallowabletemperature排空气装置Airexhaustsystem压力变化范围Pressurechangerange***Excellence0℃连续方式Continuemode420℃自动Automatic适应Adaption外型尺寸和重量/Primeout-formdimensi***andweigh产品型号Productmodel口径(DN)CalibreL法兰FlangeL螺纹/焊接Thread/weldingH1H2W重量Weight使用压力范围(Mpa)Pressurechangerange公称压力(Mpa)NominalpressureJ5N15~2025-150160771631155.65.70.1-1.21.6J5NF15~2025210230-771631158.59.20.1-1.21.6JH5NF
