Abstract
A valve structure for connecting an oil tank to a ballast tank separated by a bulkhead includes a butterfly valve bolted to a short section of flanged pipe which is welded or bolted to the bulkhead separating the two tanks in combination with a rupturable disk fitted within the pipe section and capable of withstanding the maximum pressure of either a full ballast tank or a full cargo tank. A cutting edge is secured to the rotatable disk of the butterfly valve which, upon opening of the butterfly valve, slices the disk sufficiently to assure its collapse and failure by liquid flowing through the opened butterfly valve.
