ABSTRACT:
In a preferred embodiment of the invention, an accessory safety valve is provided for mounting within outlet-ports of tanks designed to contain pressurized gas of some sort, particularly of an explosive or caustic nature, to replace the conventional outlet conduit normally mounted in such tanks which normally have the on-off valve exterior to the tank devoid of any safety back-up feature, the present accessory safety valve having the pressure-responsive safety mechanism mounted within the end of the conduit passage that extends totally inside the tank totally beyond exterior-mounting male thread to the conduit, placing the valve and valve set therefor thereby in a removed position protected against damage and failure in the event of an exterior-tank blow or impact against portions of the conduit mounted exterior to the tank.
