摘　　要：通过分析现有各种带有阀门的膜式燃气表开关阀控制技术的特点,针对现有远程开阀技术存在的安全隐患,提出膜式燃气表应具有安全开阀模式和户内燃气安检模式。通过在膜式燃气表内部安装能检测微小压差的压力传感器,使燃气表在开阀过程中能够自动检测下游管线有无泄漏,将开阀过程中存在的风险降至最低,从而实现安全、可靠地开阀。采用这种具有安全检测能力的智能燃气表,辅之以燃气经营者安全检测制度的创新,使广大的燃气用户参与到定期逐户安检中来,保证管道燃气经营者和用户的长期安全。Based on the analysis of valve control technology of existing diaphragm gas meter, this paper states that the membrane type gas meter should have safety valve opening mode and indoor gas security mode, aiming the hidden security trouble in remote valve technology. By installing pressure sensor to detect tiny differential pressure, the gas meter can automatically check if the downstream pipeline leaks, minimize the risk exists in the process. This intelligent gas meter with safety testing capabilities, complemented by gas safety inspection system, could ensure the long-term safety of gas pipeline operators and users.
