产品工作原理和用途：
美标固定球阀是新一代高性能球阀，适用于长输管线和一般工业管线，其强度、安全性、耐恶劣环境性等在设计时进行了特殊考虑，适用于各种腐蚀性和非腐蚀性介质。它与浮动球阀相比，工作时，阀前流体压力在球体上产生的作用力全部传递给轴承，不会使球体向阀座移动，因而阀座不会承受过大的压力，所以固定式球阀的转矩小、阀座变形小，密封性能稳定、使用寿命长，适用于高压、大口径场合。
产品结构特点：
1、操作省力：球体由上下轴承支撑，减少摩擦，消除了由于进口压力推动球体与密封座形成的巨大密封负荷而造成过大的扭矩。
2、密封性能可靠：PTFE单性材料密封圈嵌于不锈钢阀座内，金属阀座尾端设有弹簧保证密封圈足够的预紧力，阀门在使用过程中密封面磨损时，在弹簧作用下阀门继续保证良好密封性能。
3、防火结构：为防止由于骤热或火灾的出现，使聚四氟乙烯密封圈烧毁，发生较大泄漏，而助长火势，在球体与阀座间设置防火密封环，在密封圈烧毁时，在弹簧力作用下，将阀座密封环迅速推向球体上，形成金属与金属密封，起到一定程度的密封效果。耐火试验符合APl6FA和APl607标准要求。
4、自动泄压功能：当阀门中腔停滞的介质压力异常升高超过弹簧的预紧力时，阀座后退脱离球体，达到自动泄压的效果，卸压后阀座自动复位。
5、排泄管路：阀体上下均设置排泄孑L，可检查阀座是否发生泄漏，在工作中，阀门处于全开或全关时，卸掉中腔压力，可直接更换填料；可以排放中腔滞留物，减少介质对阀门的污染。
