Liquid and gas dispensing valve

Abstract

A metallic valve body member adapted to be welded for secure attachment against the top opening of pressurized liquid and gas supply tank is so designed as to provide for the assemblage of all non-integral parts after the welding operation, thereby permitting such additional parts to be fabricated of comparatively inexpensive materials such as synthetic plastics. A valve stem seats at its lower end against a valve seat within the valve body. Outer and inner elongated spool valve members are fixed, respectively, to lower end portions of the valve body member and the valve stem member to project within the interior of the tank. The outer spool valve sleeve is provided with a plurality of peripherally-arranged through openings, through which pressurized gas flows for dispensing past the valve seat upon the valve stem being partially open, and which openings are blocked by a lower end portion of the inner valve spool member when the valve stem is more fully opened to provide for the dispensing of pressurized liquid through the lower end of the outer spool valve member and side wall openings in the inner spool valve member. A dip tube extending from the lower end of the outer spool valve member to the bottom of the tank provides for such dispensing of pressurized liquid while the tank is in upright position. Transition zone adjustment of the valve stem provides for dispensing of a mixture of pressurized gas and liquid, as desired.
