·
OSTI ID:4034808
A safety valve design is presented. The safety valve consists of a valve seat and a valve member biased thereagainst, a diaphragm forming a seal downstream of that provided by the valve member and the valve seat, and a seal rupturing member normally downstream of and biased toward the diaphragm. Means are provided for locking the seal rupturing member in the inoperative position. The locking means is releasable by lock release means responsive to fluid pressure in the vessel. The lock means consists of a detent held in the locking position by a level operable to release the detent by an expandable chamber in communication with fluid in the vessel. (N.W.R.)
