ABSTRACT:
Disclosed is a tank bottom internal valve housing. A low profile valve housing with a valve such as a butterfly valve and a means for opening and closing the valve is assembled to a saddle on the tank bottom by a number of bolts located around the periphery of the valve housing and engaging in threaded blind holes in the tank saddle. A discharge nozzle is mounted on the lower face of the valve housing in such a way that the discharge nozzle mounting can be sheared away from the rest of the assembly during, for instance, an accident without affecting the integrity of the valve housing itself. This can be accomplished, on one hand, by using the same bolts for common mounting of the discharge nozzle, valve assembly and saddle with the bolts having a grooved portion between the valve assembly and discharge nozzle and/or a "keying effect" provided by a detent or protrusion on one of the parts consisting of the saddle and valve assembly and a mating recess for accommodating the detent is provided on the other of the parts. Another alternative of the invention contemplates utilizing bolts of smaller diameter to mount the discharge nozzle to the valve assembly than are used to mount the valve assembly to the tank saddle.
