    • A method and apparatus for detecting and preventing electrically induced fires in a gas tubing systems constructed of Corrugated Stainless Steel Tubing (CSST) and Gas Appliance Connectors (GAC). The system of the present invention may include one or more energy detection schemes to detect electrical energy surges on the gas line. When such a surge is detected, the control circuitry of the present invention causes an electric main gas valve de-energize into a closed position. In addition, the system of the present invention further includes a residual gas dispersal system that automatically vents the residual downstream gas pressure remaining in the gas tubing system after the closure of the main gas valve.

    • The present invention provides failsafe system for cutting gas off gas flow in response to electrical insults that may damage gas tubing. The invention uses an inductive sensor to detect electrical surges along a ground conductor that provides a ground path for gas tubing. The sensor is coupled to control circuitry that provides a continuous pulse train to a solenoid that forms part of a valve that controls gas flow through the gas tubing. The pulse train from the control circuitry keeps the valve open. In response to an electrical surge detected along the ground conductor (e.g., from lightning), the control circuitry stops the pulse train to the solenoid, which in turn causes the gas valve to close and stop the gas flow through the tubing.
    • 本发明提供了用于响应于可能损坏气体管道的电气损伤来切断气体流动的故障安全系统。 本发明使用感应传感器来检测沿接地导体的电涌,其提供用于气体管道的接地路径。 传感器耦合到控制电路,该控制电路为螺线管提供连续的脉冲串,螺线管形成控制通过气体管道的气体流量的阀门的一部分。 来自控制电路的脉冲串保持阀门打开。 响应于沿着接地导体(例如,从雷电)检测到的电涌,控制电路将脉冲序列停止到螺线管,这又导致气门关闭并停止通过管道的气流。
