产品特性
轨道球阀在开启和关闭时，球体先偏离阀座后再转动，消除了球体与阀座的摩擦。球体顶装式设计，直接在管线上维护；阀杆的密封由注入式填料装置，起到密封阀杆的作用，完全控制挥发性、放射性泄漏。广泛适用石油和天然气的储存和输送，进行就地/控制室控制。主要性能规范： 设计依据GBAPI结构长度JB/T 7745GB/T 12221ANSI B16.10连接法兰GB/T 9113JB/79 HG20592ANSI B16.5对焊端GB/T 12224MSS SP 44ANSI B16.25检验和试验JB/T 9092SPI 598 主要零件材料：压力等级试验压力适用环境壳体试验密封试验1.62.41.76易燃、易爆、易挥发、易聚合及剧毒场合。2.53.752.754.06.04.46.49.67.04CLASS1502.942.2CLASS3007.55.5CLASS60016.011.0适用温度-190～≤550℃适用介质水、油、天然气及各种软性介质与悬浮液等驱动方式气动、手动、电动 主要外型尺寸： 压力级主要尺寸公称通径mm253240506580100125150200250300350400450500PN1.6MPaL100180200230290310350400480600730850980110012001250H240260307360410483512543581617672723758791828870Kg9.5161928304155781152152703855028769801240PN2.5MPaL160180200230290310350400480600730850980110012001250H260280320360430490525567604642695742781815864905Kg9.51619283045598212123028940254091311201280PN4.0MPaL160180200230290310350400480600730850980110012001250H260280320360436492527607649701750750790832875910Kg101720253245598211521302954025409131124348PN6.4MPaL1601802002302903103504004806007308509801100--H280300329365450509541663725781790806821858--Kg101720253252681061682813554986891134--150LbL127140165178190203229356394457533910686762964914300LbL165178190216214283305381403502568648762838914991600LbL21622924129233035643250855966078783888999110921194
