Abstract

PURPOSE: To operate a gas shut-off device with weak electric power, by using a diaphragm type valve which is controlled by virtue of electromagnetic locking force through a lever mechanism.
CONSTITUTION: The tensile strength of a holder 8 in the arrow direction is increased by a lever mechanism against the electromagnetic locking force of an exciting coil 22. A spring 24 is so applied that it normally turns a magnetic path controller 23 in the direction of yoke 21. Another spring 25 repels the holder 8 in the arrow direction to press a diaphragm 14 to a partition wall 13 through a lever mechanism of connecting rod 5. Being the system so composed, the diaphragm can generate a force worth about 1kg through the rod's lever mechanism, even if the spring 25 pressing the diaphragm 14 is about 300W400g. In addition, the electromagnetic locking force may be 1/5 or 1/6 of the spring force due to the lever mechanism of the magnetic path control plate 23.
