ABSTRACT:
An improved flame snuffer 30 for utilization on the vent line 20 of oil field atmospheric condensate storage tanks 10 is disclosed utilizing a valve 200, a fusible link 70, and a counterweight 80 connected to the valve 200 so that when the fusible link 70 melts in the presence of fire the counterweight 80 is released to close the valve over the vent 20. A container 40 holds the valve 200 and directs the outlet 22 of the vent line 20 into a downward path 100. A rod 50 connected to one end of the valve 200 has the counterweight 80 connected to its opposing end and the fusible link 70 is connected to the rod 50 and to a rigid arm 80 so that in the presence of a fire, the fusible link 70 melts releasing the rod 50 from the arm 80. A manual override 110, 120 is further provided to separate the rod 50 from arm 80 when a predetermined force is exceeded.
