U41SM法兰柱塞阀良工阀门集团有限公司一、U41SM法兰柱塞阀结构及特点：柱塞阀是由阀体、阀盖、阀杆、柱塞、孔架、密环、手轮等零件组成（如图）。当手轮旋转时，通过阀杆带动柱塞在孔架中间上下往复运动来完成阀门的开启与关闭功能。在阀门中柱塞与密封环间采用过盈配合，通过调节压盖中法兰螺栓，使密封环压缩所产品生的侧向力与阀体中孔面及柱塞外圆密封，从而保证了阀门的密封性，杜绝了内泄漏、同时阀门开启矩小、能实现阀门的迅速开启和关闭。由于密封环采用回弹性强、耐磨性高的无毒新型密封材料，具有经受长期高温、高压而不丧失弹性，所以密封性能可靠，经久耐用。二、U41SM法兰柱塞阀参数和性能指标：型号公称压力（Mpa）试验压力（Mpa）工作温度适用介质强度密封U41S-161.62.41.76-20-250°C瞬时≤３００°C水、蒸气、油品、氨、醋酸铜氨液及酸性介质等U41S-252.53.752.75U41S-404.06.04.4三、U41SM法兰柱塞阀主要零件材料：序号零件名称灰铸铁铸钢不锈钢ZCP1阀体阀盖HT200WCBZG1Cr18Ni9Ti2柱塞ZG1Cr18Ni9TiZG1Cr18Ni9TiZG1Cr18Ni9Ti3阀杆45451Cr18Ni9Ti4密封环聚四氟乙烯+石墨+高弹性胶（8202型）四、U41SM法兰柱塞阀主要外形尺寸：型号公称通径DNLDD1D2fbz-фdDoHH1W(kg)U41S-16-16C151309565452144-14801161442.82015010575551614217652516011585651001632056.53218013510078184-181201822278.54020014511085318021026012502301601251002023028617652901801451202002503102280310195160135228-182402693403010035021518015524278356411254002452101852637533244070150480280245210288-23434562902006003352952653012-234604986601202507304053353203212-25540720220300850460410375434650850340U41S-25151309565452164-148011614432015010575551424765.22516011585651001632056.83218013510078184-181201822278.94020014511085318021026012.4502301601251002023028617.565290180145120228-1820025031022.68031019516013524026934031100350230190160248-2327835644125400270220188288-253753324407815048030025021830434562100200600360
