蒸汽波纹管截止阀产品简介：蒸汽波纹管截止阀是指安装在蒸汽管道上，用波纹管作为阀杆密封元件，可使阀杆部位无泄漏，以防止蒸汽外漏的截止阀。是锅炉蒸汽***理想阀门。没有流体流失提高了使用能源效率增加生产设备安全性减少了维护费用及频繁的维护***降低经营成本，还提供了清洁安全的工作环境。蒸汽波纹管截止阀工作原理：蒸汽波纹管截止阀引进国外***技术，采用双重的密封设计若波纹管失效阀杆填料也会避免泄漏，波纹管焊于阀杆保持稳定的运行性能，避免由于阀塞振动引起阀杆振动。完全消除了普通阀门阀杆填料密封老化快易***的缺点，在高温情况下，阀杆不与介质接触，保证阀杆的零泄漏。蒸汽波纹管截止阀产品特点：1、双重的密封设计（波纹管+填料）若波纹管失效，阀杆填料也会避免。2、杜绝外泄漏并符合国际密封标准。3、没有流体损失降低能源损失提高工厂设备安全。4、使用寿命长减少维护次数降低经营成本。5、坚固耐用的波纹管密封设计保证阀杆的零泄漏提供无需维护的条件。蒸汽波纹管截止阀技术规范：结构形式c***tructionBB-BG-OS&Y驱动方式operation手动hand-operated气动pneumatic设计标准designstandardDIN3356结构长度facetofacedimensionDIN3202连接法兰flangedendsDIN2543-2545试验和检验test&inspectionDIN3230蒸汽波纹管截止阀产品性能规范：公称压力(MPa)nominalpressure壳体试验压力(MPa)shelltest密封试验压力(MPa)sealingtest适用温度(℃)suitabletemp适用介质suitablemadium1.62.41.76-20℃-350℃水、蒸汽、油品等water,steam,oil,etc.2.53.752.754.06.04.4蒸汽波纹管截止阀主要零部件材质：序号NO.名称partname材质material1阀体bodyWCB、F304、F3162阀瓣disc2CR13、F304、F3163轴销hingepinF304、F3164波纹管组件bellowscombinationF304、F316L5阀盖bonnetWCB、F304、F3166填料packing柔性石墨Flexiblegraphite、PTFE7压套gland25#、F304、F3168***片locator25#、F304、F3169阀杆螺母stemnut铜合金ZQA19-410手轮handwheel碳钢carbonsteel11并帽cap25#12油杯oilcup黄铜brass13六角螺母hexagonnutASTMA1932H、A193-8、A193-8M14双头螺栓boltASTMA193B7、A193-B8、A193-B8M15垫片gasket柔性石墨+不锈钢flexiblegraphite+stainlesssteel、PTFE16阀杆stem2Cr13、F304、F316☆产品尺寸：蒸汽波纹管截止阀WJ41H-16压力等级pressurePN16口径size1520253240506580100125150200250300L130150160180200230290310350400480600730850H205205217230235240285310370430445560695740W120120140140160180180200250300300400520520重量(kg)Weight4.54.85.57.89.512.718.623.539.556.876.1115237.2399.5行程h77121314151923283542526475Kv4.27.4121930477712018828841072511451635蒸汽波纹管截止阀WJ41H-25压力等级pressurePN25口径size1520253240506580100125150200250300L130150160180200230290310350400480600730850H205205217230235240285310370430445560695740W120120140140160180180200250300300400520520重量(kg)Weight4.54.85.589.81319.224.343.757.981.6137288.1420行程h77121314151923283542526475Kv4.27.4121930477712018828841072511451635蒸汽波纹管截止阀WJ41H-40压力等级pressurePN40口径size1520253240506580100125150200250300L130150160180200230290310350400480600730850H205205217230235240285310370430445560695740W140140140160180180200250300350350450520520重量(kg)Weight4.54.85.58.310.513.620.525.646.161.285159308.5445行程h77121314151923283542526475Kv4.27.4121930477712018828841072511451635)
