美标球阀产品说明：
美标锻钢球阀Q947F-150LB/Q947F-300LB/Q947F-600LB，AQ341F-150LB/300LB/600LB美标球阀结构简单，密封性能好，用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、用品、液化气、天然气、煤气、硝酸、醋酸、氧化性等介质。浮动式球阀主要包括：一片式、两片式、锻钢分体式设计。采用阀杆防吹出设计、防静电结构的设计、低泄漏结构的设计、防止阀杆的磨损和误操作的设计、防火结构的设计等。所有的浮动球阀均按照GB/T 12237设计，并且防火试验满足API 607的要求。阀杆采用防吹出结构设计的整体T形结构，即使在阀腔异常升压以及填料压板失效等情况下，也能保证阀杆不会被介质吹出。美标球阀的阀杆嵌入阀体内部，具有倒密封的功能，倒密封的密封力随着介质压力的增高而增大，故能在各种压力下均能确保阀杆的可靠密封。
美标球阀防静电结构的设计：
美标球阀防静电结构采用弹簧-钢球式静电引出装置，使球体与阀体之间直接形成静电通道的球阀或通过阀杆使球体之间形成静电通道的球阀从而可将球体与阀座开关过程中摩擦产生的静电通过阀体引到地，避免静电火花可能引起的火灾或爆炸等危险。
