ABSTRACT:
A stuffing box for use in a control for an emergency valve for controlling discharge from a liquid storage tank, such as a gasoline storage tank, with the tank having an outlet port with a conduit member coacting with the port in depending relation therefrom. The stuffing box is adapted to be mounted on the conduit member and to extend from the interior to the exterior thereof. The stuffing box comprises a barrel member defining a passageway open at opposite ends. A crank including a shaft rotatably disposed in the passageway of the barrel member is mounted on the barrel member. Sealing means coacts between the shaft and the barrel member for sealing the shaft against leakage of liquid from the conduit lengthwise of the barrel member, and a releasable non-threaded detent is disposed generally adjacent the exterior end of the barrel member for locating and maintaining the shaft relative to the barrel member lengthwise thereof. The arrangement is such that the stuffing box is resistant to corrosion and freezing-up, and is adapted to provide long service life to the control for operating the emergency valve, while providing for expeditious replacement of the seals thereof.
