ABSTRACT:
The gas distribution system has a main gas line in gas flow connection with several components including a gas pressure safety structure. A pressure regulator is located on a front or forward portion of the main gas line and reduces the gas pressure at a point in the main gas line subsequent to the pressure regulator. There is an auxiliary gas line that extends from a point on the main line before the gas pressure regulator to the gas pressure safety structure. The gas pressure safety structure has in gas flow connection a source pressure regulator, as inspirator and a pressure sensing pilot all in gas flow connection with a gas venting device. Upon overpressurization the pressure sensing pilot will be activated and the inspirator will cause a vacuum to be formed in its connection with the gas venting device. This vacuum will open the gas venting device to permit the excess gas to be vented to the atmosphere.
