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.

Abstract: An accumulator having a housing, a spring-loaded liquid inlet-outlet valve, a gas charging and release valve, and a gas-liquid separator in which a top is provided releasably connected to the housing for servicing the accumulator from the top. The top is slidably insertable into the top of the housing and a releasable lock is positioned externally of the top for locking the top in the housing. The lock is prevented from releasing while the top is held in an upward position by pressure in the housing and can only be released when the pressure in the housing is reduced and the top is moved downwardly. The locking means includes a notch in the exterior of the housing, a locking ring, and a backup shoulder on the exterior of the top. An anti-extrusion ring is bonded on the bottom edge of the top and slidably engages the interior of the housing for preventing damage to the separator. Preferably the top includes a dome and an annular flange extending around the lower end of the dome. The liquid inlet-outlet valve is a poppet valve in which the valve element is enclosed by a resilient coating with an annular resilient ring bonded to the coating and positioned to seat on the valve seat. The separator may be a bag separator or a cylindrical solid float having a tapered bottom with a plurality of axially extending recesses about its outer periphery for preventing the float from sticking on the interior of the housing.
