Abstract

PURPOSE: To facilitate the change in the adjustment of working sensitivity along with an accurate action while simplifying the returning to the normal condition after action in an apparatus for automatically closing the cock whenever abnormal vibration is applied by earthquake or the like.
CONSTITUTION: When vibration works from outside, a pendulum 2 including a spindle 5 with a ginbal 6 at the upper portion thereof swings horizontally on the upper portion. When the swing exceeds the set seismic intensity, a working arm 3 turns counterclockwise on the fulcrum 18, which causes a hook 3a at the tip to be disengaged from a engagement receiving hole 20 of a rotary wheel 19. Thereupon, the wheel 19 turns clockwise by a springing force of a pair of working springs with one end retained thereon and the other end fixed to a casing 1 through a lock fitting 28 to close a cock 23. To open the cock again, the wheel 19 is turned counterclockwise until the hook 3a engages the receiving hole 20.
