Abstract
A drain for a pressure vessel includes a valve, a knob, a tube, a passageway, and a drain cup. The valve is coupled between an interior surface and an exterior surface of a tank. The knob is coupled to the valve for opening and closing the valve. The tube has a top end and a bottom end and is coupled to the valve at an interior surface of the tank at the top end and extends into a bottom of the tank at the bottom end. The passageway extends through the valve and has an opening coupled to the tube at a first end and an exit at a second end. The passageway is openable and closeable by the knob. The drain cup is associated with the exit of the passageway and is positioned on an exterior surface of the tank for collecting condensation from the interior of the tank. The valve is positioned at a height that is vertically higher than the bottom end of the tube.
