ABSTRACT:
An apparatus and associated method for relieving the pressure within a high pressure tank having an opening plugged by a broken safety valve of a special type utilizes a mechanism acting between the annular flange of the tank normally provided for the securement of a valve protector cap and the valve to permit pressurized contents confined within the tank to escape through the valve. The special valve includes a flow passage in axial alignment with the tank opening in which the valve portion is received and defines a ball chamber in which a spherical ball is seated. The apparatus of the invention includes a stem which is movable through the valve portion flow passage for engagement with the spherical ball to thereby unseat the ball and open the valve flow passage. By unseating the ball, contents of the tank pass out of the valve flow passage and are directed either into the atmosphere or another vessel for reclaiming purposes. The method of the invention includes the steps of utilizing the apparatus of the invention.
