A thermally activatable safety valve apparatus is provided with a timing assembly and valve means operationally associated with the timing assembly. First and second fluid transmission means are provided through the apparatus, with one of the first and second fluid transmission means being isolatable by activation of the timing assembly. A thermally activatable trigger means isolates the other of the said first and second fluid transmission means and also initiates the closure of the valve means associated with the timing assembly. Upon activation of the present thermal safety valve, control fluid upstream of the apparatus is isolated from the transmission line downstream of the apparatus, and downstream control fluid is permitted to dump through the apparatus for a predetermined period of time, at the conclusion of which the said valve means associated with the timing assembly completes closure which isolates the downstream control fluid, whereby the hazards of additional and potential fire fuel are greatly reduced.
A thermally activatable safety valve apparatus comprising:
In a safety valve apparatus having a housing, a timing assembly within said housing, valve means operationally associated with said timing assembly, and a plurality of fluid transmission means through said housing, the improvement comprising a thermally activatable trigger means for isolating one of said fluid transmission means and for initiating closure for the valve means operationally associated with said timing assembly.
