工作原理：球芯与压敏阀座C贴合密封的压力会传递到压力敏感元件上；阀体内压力变化的流通介质对不同开度的球芯产生不同的作用力，通过压敏阀座叠C加到压力敏感元件上；阀芯开度不变，叠加力随介质压力变化，介质压力不变，叠加力随阀芯开度变化。同样的，阀杆环形凸部对压敏阀座B贴合密封的压力也会传递到压力敏感元件上，而液体或气体通过液敏或气敏元件时会导致其输出电信号变化。智能球阀工作时，预警发射器接收压敏阀座输出的信号，经放大和数字处理后与内置的数据进行比较分析，在压力检测值接近临界值时判断球阀即将泄漏而发出预警，在液体或气体敏感元件信号异常时判断球阀发生外漏而发出警报；同时，预警发射器将检测处理的有关数据信息传输到物联网，物联网上位机根据预紧发射器传来信息结合积累的大数据，判断球阀的内外密封面是否即将泄漏，球阀是否已经发生泄漏，球阀的开度及流通介质的压力参数是否处于正常的工作范围内，进而通知相关人员采取相应措施，防止泄漏事故发生，维持生产的正常进行。

工作原理：手轮上旋时，阀瓣随阀杆上移，截止阀开启，阀瓣密封环不与阀瓣贴合，压敏阀座输出信号随介质压力大小而变化；手轮下旋时，阀瓣随阀杆下移，阀瓣密封环与阀瓣贴合形成密封，截止阀关断，压敏阀座输出信号随密封面比压大小而变化；压盖压紧时，压敏阀座与密封圈及阀杆紧密贴合，密封面比压大于临界值，截止阀介质不外漏，反之，密封面比压小于临界值，截止阀介质外漏；预紧发射器根据压敏压敏阀座输出的信号判断截止阀的开与关、关闭时是否内漏并判断介质压力大小，根据压敏阀座输出信号的变化，判断截断阀是否外漏；预紧发射器还将上述状态数据发送到物联网供远程监测和管理。
