一、产品简介柱塞阀的结构（如图所示）特点是由一个不锈钢柱塞和上下两个富有弹性的密封环，以及能保持上下密封环固定距离的金属框架组成，柱塞尤如瓶塞一般地插入两密封环中形成圆柱形接触密封，其密封面积之大是传统截止阀无法可比的，密封效果特佳，上密封环防止外泄漏，下密封环起内密封作用，若久用之后出现渗漏时，可通过调节阀盖上固定螺栓的压力（先将阀口处于关闭状态）使密封环端面上的密封比压增加，导致经向分力增加，使之泄漏的密封环重机关报恢复密封，我厂经过多次过盈密批配合的密封试验，确定了合理的过盈密封值，经往复运动百万次，仍能完全可靠地提供良好的密封效果。二、主要技术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U41SM-16C1.62.41.76-20-250°C瞬时≤３００°C水、蒸气、油品、氨、醋酸铜氨液及酸性介质等U41SM-252.53.752.75U41SM-404.06.04.4三、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、主要外形尺寸型号公称通径DNLDD1D2fbz-фdDoHH1W(kg)U41SM-16C151309565452144-14801161442.82015010575551614217652516011585651001632056.53218013510078184-181201822278.54020014511085318021026012502301601251002023028617652901801451202002503102280310195160135228-182402693403010035021518015524278356411254002452101852637533244070150480280245210288-23434562902006003352952653012-234604986601202507304053353203212-25540720220300850460410375434650850340U41SM-25151309565452164-148011614432015010575551424765.22516011585651001632056.83218013510078184-181201822278.94020014511085318021026012.4502301601251002023028617.565290180145120228-1820025031022.68031019516013524026934031100350230190160248-2327835644125400270220188288-2537533244078150480300250218304345621002006003603102783412-264604986601342507304253703323612-3054072022030085048543039044016-30650850340U41SM-40151309565452164-148011614432015010575551421765.22516011585651001632056.83218013510078184-181201822278.94020014511085318021026012.450230
