摘要
论述燃气表专用压力传感器的结构及工作原理,燃气表低压力安全切断控制技术的原理、安全复位功能,切断阀的结构、原理、关键技术特点及性能指标。通过将燃气低压力感知技术与燃气表安全切断控制技术相结合,实现燃气表对燃气异常低压力的感知和安全切断。
The structure and working principle of the special pressure sensor for gas meter, the princi- ple of gas meter low pressure safety cut-off control technology, safety reset function, and the structure, principle, key technical characteristics and perform- ance indicators of cut-off valve are discussed. By com- bining the gas low pressure sensing technology with the gas meter safety cut-off control technology, the gas me- ter can sense the abnormal low pressure and safely cut off the gas meter.
