Y2
Abstract:
A purged valve assembly and method of sealing for a liquid transmitting casing that extends into a storage reservoir for liquid or liquified gases. The assembly includes a normally closed spring-biased foot valve mounted on the lower end of the casing. A pump and motor unit slidably mounted in the casing opens the foot valve when resting thereon. A purged double seal on the foot valve prevents any leakage of liquid or liquified gas inwardly through the valve into the interior of the casing when the pump and motor unit is lifted off the foot valve.
