Abstract

PURPOSE: To shut off gas feed in case of an earthquake, by magnetically adsorbing a valve to the gas feed port.
CONSTITUTION: As an earthquake occurs, a weight 8 is oscillated by a spring 6 back and forth, to and fro, which makes a magnet supporting arm 9 of a quake sensing rod 7 separated from a fitting end 16 of a permanent magnet 10. Then the magnet 10 leans to the right and falls down. The fallen magnet 10 is magnetically adosrbed by magnetic reacting plates 17 of magnetic induction plate 4 after colliding with the plates 17. Magnetic poles N, S are generated on both reacting plates 17 at this moment, respectively. A valve 13, which is fixed through a hinge 14 to the magnetic induction plate 4 in a valve chamber 3, is magnetically adsorbed by the magnetic reacting plate 17 from its hanging position. As a result, a gas port 12 is blocked by the valve 13.
