Abstract

A gas-liquid spherical accumulator which includes a spherical integral cast metal housing having top and bottom ports. The top port is adapted to receive a gas valve and the bottom port releasably supports a circular valve seat. A vertical guide rod is connected to the valve seat and extends upwardly in the housing. A generally cylindrical solid float is slidably mounted on the rod. The float has a rounded valve element on the bottom for seating on the valve seat closing off the bottom port. The diameter of the float is less than the diameter of the bottom port whereby the float may be removed through the port. A resilient coating is bonded on the valve seat or the valve element and preferably includes a circular ring projecting outwardly. The valve seat tapers downwardly and inwardly. A seal is positioned on the guide rod for engaging the bottom of the float for preventing gas escape. The rod, float and valve seat may be replaced with a bladder and poppet valve.
