ABSTRACT:
A quick-connect cylinder valve and connector provides a tank connector half mounted in a high-pressure tank containing liquefied carbon dioxide and a base connector half mounted in an upright position. Each connector half provides a valve which is closed when the connector halves are not connected. The connector operates to support the tank in a vertical position and is arranged to provide easy installation and removal of the tank even in confined locations in which access is limited. The two connector halves provide cylindrical telescoping surfaces which align the connector halves during initial assembly. After the connector halves are aligned, a probe on the base connector half enters a seal on the tank connector half to form a fluidtight joint therebetween. Thereafter, at full assembly, the probe opens the valve contained ijn the tank connector half. The weight of the tank and its contents opposes the blowoff force created by the pressure within the assembled connector. Such blowoff force is a function of the diameter of the probe, which is sized so that excessive blowoff of reaction forces does not exist. A bayonet lock prevents accidential blowoff from occurring.
