摘　　要：提出了基于超声波传感技术的阀门填料函处气体泄漏在线监测方法。利用传感器识别气体泄漏产生的气泡并输出低电平的原理,创新性的将超声波传感器与传统的智能阀门定位器控制功能进行了集成,实现对阀门填料气泄漏的实时在线监测,确保阀门安全、稳定运行,最大程度降低阀门泄漏监测成本,也填补了我国在阀门外泄露在线监测领域的一大技术空白,为石油、化工、电力等领域气体泄漏防治提供了解决方案。An online monitoring method for gas leakage at the valve packing based on ultrasonic sensor technology is proposed.An ultrasonic sensor is designed using the principle that the sensor identifies the bubbles generated by gas leakage and outputs low-level signals.Innovatively,the ultrasonic sensor is integrated with the traditional intelligent valve positioner control function to achieve real-time online monitoring of the control valve packing gas leakage,ensuring the safe and stable operation of the valve,minimizing the cost of valve leakage monitoring,and filling a major technological gap in China's online monitoring of valve external leakage.This provides a solution for the prevention and control of gas leakage in petroleum,chemical,electric power and other fields.
