Abstract
A locking ring assembly is provided for releasably retaining a tubular valve housing in the liquid port of a bladder-type pressure accumulator without any possibility of the valve housing being blown out from the port when a normal high pressures are attained within the accumulator shell. The locking ring assembly seats at an angle against an identical angle on the inside of the opening at the mouth of the accumulator shell so that when excessively high internal pressures are reached within the shell the ring will force the mouth of the shell to expand diametrically forcing the mouth open thus extruding an O-ring seal which releases the pressure. Thus the accumulator shell cannot burst.
