GAS VALVE

摘要

A valve comprising a housing (12) fitted with a valve coupling port (20) being in flow communication with a gas inlet valve component (24) and an independent gas discharge valve component (26). The gas inlet valve component (24) comprises a normally closed valve inlet port (38) and an outlet barrier (42) configured for spontaneous opening to thereby facilitate only ingress of ambient gas into the housing upon pressure drop at the valve coupling port (20). The gas discharge valve component (26) comprising a valve discharge port (62) and a displaceable float member (66) to thereby facilitate spontaneous egress of substantially only gas from the housing (12) and remain closed upon presence of liquid within the housing (12).
