Abstract

PURPOSE: To block momentarily a gas passage in case of earthquake by virtue of a change in the direction of magnetic field, by setting a vertically and horizontally movable magnetic board above a magnetic valve for controlling the gas passage in a hermetic case.
CONSTITUTION: Concave portions 2, 3, communicated with each other, are made on the gas inlet and outlet sides of a hermetic case 1 in which a gas passage is formed. A magnetic valve a, set in the concave 2, is composed of a vertically movable bottom board 5 and upper board 6 having a projection board 8 at the center on its upper side, a magnet 7 being buried in the projection board 8. Another case 10, put on the case 1, has a magnetic board b suspended inside, having a magnet 12 at the lower end of a weight 11 and a shaft rod 13 at the upper end being held by a spring 15 at a hole 14 of the case 10. The magnetic force of both magnets 7, 12 is so designed that the magnetic valve a drops because of a change in the direction of magnetic field caused by oscillation of the magnetic board b, when both magnets 7, 12 are aligned on the same vertical line.
