成したことを特徴とするガス遮断装置。 The box body is provided with a gas passage through which gas can flow from the bottom to the top, a support member is provided at the bottom outside of the gas passage, and a magnet that can move vertically along the gas passage is placed on the support member. At the same time, a ball receiver carrying a ball valve is supported in the gas passage by the magnetic force of a magnet, and a valve hole that is closed when the ball valve rises is formed in the gas passage above the ball valve. An excitation coil is provided below the magnet and is excited in response to an electric signal emitted by a sensing means for detecting leakage gas.The excitation coil is configured to generate a magnetic force capable of repelling the magnet, When gas leaks out, the ball valve floats due to the flow pressure of the gas and the gas passage is closed. Also, when the sensing means detects leaking gas, the excitation coil is energized to cause the ball to float together with the magnet. A gas cutoff device characterized in that a ball valve floats up through a receiver to close a gas passage.
