摘要
从安全切断阀、安全切断感知与控制技术、通信技术、安全切断的智能管理与网络服务方面探讨安全切断型智能燃气表的安全切断技术。提出安全切断阀的开关阀电流、使用寿命、安全切断阀关闭后的密封性(切断阀泄漏率)、开关阀时间等指标的推荐值。
The safety shut-off technology of safety shut-off type smart gas meter is discussed in terms of safety shut-off valve, safety shut-off perception and control technologies, communication technology, intelligent management and network service of safetyshut-off. The recommended values of safety current for opening and closing shut-off valve on-off, service life, tightness of safety shut-off valve after closure （ shut-off valve leakage rate） and time for opening and closing shut-off valve on-off are proposed.
