ABSTRACT:
A safety valve device for a compression gas cylinder to shut off gas flow at the tank port of the cylinder when downstream gas flow control apparatus is structurally distrupted is set forth which includes a housing having a conduit therethrough for the passage of gas where the housing is adapted for fitting into the tank port of the cylinder. A poppet seat is located in the conduit and is in a fixed position relative to the tank port. A poppet which passes through the poppet seat is adapted to close the conduit when the poppet bears against the poppet seat. A helical spring is used to bias the poppet to bear against the poppet seat such that the conduit would be normally closed. However, a frangible set-off columnar member is compressively disposed between the poppet and the gas control apparatus such that structural disruption of the gas control apparatus will cause the frangible set-off member to break thereby closing the conduit and preventing gas flow from the compression gas cylinder.
