Apparatus and method for detection and cessation of unintended gas flow

摘要

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 two-way main gas valve to de-energize into a position wherein the flow of gas from a gas feeder pipe to the gas tubing system is blocked and residual gas pressure in the gas tubing system is automatically vented to the atmosphere.

主权项

1. An apparatus for preventing electrically induced fires in gas tubing, comprising:
(a) a sensor mechanism for detecting electrical insults to a gas tubing system; (b) an automated gas cut-off system that stops the flow of gas from a gas feeder pipe to the gas tubing system in response to a detection of an electrical insult by the sensor mechanism, wherein said automated gas cut-off system comprises a two-way valve configured between the gas feeder pipe and the gas tubing system, said two-way valve having a first position, which fluidly connects the gas feeder pipe to the gas tubing system; and a second position, which fluidly blocks the gas feeder pipe from the gas tubing system and fluidly connects the gas tubing system to open air.
