进口气动薄膜波纹管调节阀德国（莱克）原装进口气动波纹管密封调节阀10T50系列波纹管密封套筒调节阀，采用套筒导向，压力平衡式阀芯，适用于压差较大的场合。利用平衡密封环代替上阀座，使传统的套筒双座阀结构变为套筒单座结构，这一改进大大提高了套筒阀的泄漏等级。阀盖处采用波纹管加填料双重密封，从根本上杜绝了介质外漏的可能性。该类型调节阀适用于***或者珍贵介质的流量压力控制。阀芯利用压力平衡式结构，启闭力小通过较小的执行机构推力就能控制高压差的工况。密封性能好、允许压差大。套筒导向，导向面积大，稳定性好，结构紧凑，可以快速在线更换阀内件，维修效率高，节约人力和时间。平衡式阀芯结构确保所需的执行机构推力***小。he10T50Seriesbellowssealcagecontrolvalveadoptsthecageguidedstructureandpressurebalancedplug.Itissuitableforapplicati***withrelativelyhighdifferentialpressure.Thebalancedsealringreplacestheupperseattochangethetraditionalcagedouble-seatstructureintothecagesingle-seatstructure.Thisimprovementhasgreatlyenhancedtheshut-offclassofthecagevalve.Thedoublesealingstructureofthebellowsandpackingisadoptedatthebonnettothoroughlyeliminatethepossibilityofmedialeakingtotheoutside.Thiskindofcontrolvalveissuitableforflowandpressurecontrolofpoisonousorpreciousmedia.Theplugmakesuseofthepressurebalancedstructure,theopeningandclosingforceislowandthemediaunderserviceconditi***withhighdifferentialpressurecanbecontrolledthroughrelativelylowactuatorthrust.Withsuchfeaturesasgoodsealingperformance,highallowabledifferentialpressure,cageguiding,largeguidingarea,goodstabilityandcompactstructure,itcanrealizefastreplacementoftrimsonthelinewithhighmaintenanceefficiency,s***ingmanpowerandtime.Thebalancedplugstructuremakessurethattheactuatorthrustrequiredisthelowest.控制阀参数说明Parametersofcontrolvalves：公称通径DNDN15-600(mm)阀内件特点：双阀座结构,套筒导向阀体类型：直通式,角式阀盖形式标准型,散热型,波纹管型流量特性等百分比,线性,快开压力等级：PN1.6、4.0、6.3Mpa（ANSI150、300、600LB）泄漏等级：A***EB16.104Ⅴ（标准型金属阀座）管道连接方式法兰式,对焊式适用温度范围：-196°～550°执行机构类型气动薄膜式执行机构,气动活塞式执行机构,电动执行机构)
