BQ41H一体式保温球阀产品特点该产品具有良好的保温保冷特性,且阀门的通径与管径一致,同时又能有效降低管路中介质热量损失。主要用于石油、化工、冶金、制药、食品等各类系统中，以输送常温下会凝固的高粘度介质。由于采用整体式结构，因而保温球阀比一般球阀体积更小，重量更轻，且无外漏,密封性能良好，夹套采用碳素钢管焊接比铸造的更加耐压牢固。FeaturesTheproductbearsf***orableheat-preservationandcold-insulationaddition,theall-diameterofthevalveisidenticaltopipediametertoeffectivelyreducetheheatlossfromthosemediuminthepipeline.Itismainlyappliedtotransportthefull-bodiedmediumswhichsolidifyundernormaltemperatureinsuchfieldsaspetroleumindustry,chemicalindustry,metallurgicalindustry,pharmaceuticalindustry,foodindustry,etc.Forthemonolithicc***tructionisappliedindesigntheproduct,thejacketvalvewithf***orablesealingperformancefeatures***allerconfigurationandweightthantraditionalballvalveswithoutleakage.Moreoverpressure-resistantandfirmercapacitiesarealsoenjoyedbythejacketmadethroughcarbonsteelweldingthanthatthroughcasting.技术规范TechnicalSpecification设计标准DesignStandardA***EB16.34GB/T12224结构长度StructurelengthA***EB16.10GB/T12221连接法兰ConnectingflangeA***EB16.5JB/T79驱动方式Drivingmanner手动、电动、气动Manual,Motondriving,Pneumatil试验和检验Test&InspectionJB/T9092API598适用介质Applicablemedium重油、胶类等易凝固介质He***yoil,glueandothereasy-clottingmedium主要零件材质表FormofMajorPartsMaterials序号零件名称Accessoryname材质MaterialGBASTM1夹套Jacket25A1052阀座SeatWCBA216-WCB3阀体Body25A1054密封圈SealingRingPTFE、对位聚苯PTFE、Counterpointpolypheny15球体Ball6阀杆Stem1Cr13A247-4107填料Stuffing柔性石墨Graphite8填料压盖GlandWCBA216-WCB注：系列阀门主要零部件及密封面的材质可根据实际工况条件或用户特殊要求设计选用.Notes:Majorpartsofthevalveseriesandmaterialsofsealingsurfacedifferaccordingtoactualworkingconditionandcustmer’sspecialrequirement.)
