ABSTRACT:
A valve assembly is provided for controlling the flow of liquid accumulated in a closed vessel through a drain port in the bottom wall of the vessel. The assembly includes a body member having a first section disposed within the drain port. The body member has a second section extending outwardly from the first section. The first and second sections are provided with a first passage for air venting the vessel interior, a second passage for controlled draining of the accumulated liquid from the vessel interior, and a common opening, the latter having an exposed end. Adjustably mounted on the body member is a valve member having a first segment adjustably disposed with respect to the opening of the body member and a second segment projecting outwardly from the first segment and subtending the body member second section. The valve member second segment is provided with first and second passages corresponding with the first and second passages of the body member. Seal elements are provided on the body member second section and in encompassing relation with ends of the first and second passages formed in the body member. When the valve member is in one position of adjustment, the corresponding first and second passages communicate with one another thereby effecting drainage of the accumulated liquid. When in a second position of adjustment, at least the corresponding first passages are not in communication whereby no drainage occurs.
