Quick-disconnect fitting for gas line connection |
摘要 |
A quick-disconnect fitting for quick connection or disconnection of an oxygen line, for receiving a gas line plug of the type having a plug flange to provide gas to an oxygen line terminated by the plug. A metal valve body has a threaded inner end for being threadably received by a source of pressurized oxygen and an outer end carrying a molded plastic cap having a receptacle for receiving the plug. The valve body includes a plunger-type valve axially shiftable therein between open and closed positions, the valve carrying at its upper end a poppet for sealing engagement with a valve seat of the valve body when the valve is closed. A compression spring surrounds the valve for urging it into closed position. A nose of the plug engages and maintains open the valve member when the plug is received within the cap for receiving gas from the source. The cap carries a locking plate for selective locking engagement with the plug flange when the plug is received. The cap receptacle is cross-sectionally configured for unique mutual engagement of the plug for preventing its connection to an improper source.
