Abstract
PURPOSE: To obtain the valve device which performs valve closing operation certainly and electromagnetically, in interlocking with a gas leak alarm device.
CONSTITUTION: When gas leaks, a gas leak alarm device (not shown in the figure) operates, and electric current flows in an electromagnet 5, and the magnetic core 5a inserted into the hole 5b on a block body 1 is excited, and a sliding valve 4 is attracted and lowered. Then, the valve part 4c of the sliding valve 4 which is attracted and lowered squashes the center part of an airtight hose 6, and gas flow in a gas passage 2 is obstructed. As the both ends of the hose 6 continue to be closely fitted airtightly onto the inner surface of the gas passage 2 likewise in the former state by the action of the reinforcing parts 7 and 7, even if the center part of the hose 6 described th above is squashed, so gas leak from the valve seat 3 or the hole 5b is not generated. Thus, gas flow in the gas pipe 9 is obstructed, and gas leak is halted.
