The disconnect coupling (D) includes a fitting flange (14) to be mounted to the drain (10) of the tank (C), a plug (18) movably secured in the flange (14) and having flow and non-flow positions, and a coupling (D) which lockingly engages with the flange (14) and cooperates with the plug (18). The coupling (D) includes a plug drive pin and a valve disposed coaxially therein. Individual drive knobs are provided for the plug drive pin and valve to cause axial translation thereof relative to the coupling and to each other. The safety cap (S) includes a fitting flange (14) to be mounted to the drain of the tank (C), a plug (18) movably secured in the flange, and a coupling which lockingly engages with the flange (14) and cooperates with the plug (18). The safety cap (S) insures the proper, secure, and tight positioning of the plug (18) in the fitting flange (14) and maintains it in the non-flow position.</p> |
