Claims

[Scope of utility model registration request]

A body including a cylinder portion on a valve seat between an inflow passage and an outflow passage, a cover disposed on the cylinder portion of this body, and a peripheral portion inserted and engaged at a joint between the body and the cover. a diaphragm made of an alloy having a shape memory effect that moves in a direction toward the valve seat when the valve seat is stopped and reaches a transformation temperature; It consists of a valve body which is disposed so as to be slidable while the valve is being held, and whose valve portion is disposed facing above the valve seat, and an electric heating element which is disposed on the diaphragm so as to be operable to be energized from the outside. A diaphragm valve characterized in that the diaphragm is heated to its transformation temperature by an electric heating element and displaced in a direction approaching the valve seat, thereby pushing the valve body and closing the valve seat.
