In the flow control valve equipped with the above, the valve flow passage is constituted by a first valve flow passage and a second valve flow passage arranged in parallel, and two types of shape memory alloys having different operating temperatures are connected in series. A coil spring is provided, and when the coil spring is energized and reaches a predetermined temperature, it expands to drive the plunger and open one or both of the first valve flow passage and the second valve flow passage. A flow control valve characterized in that it is closed to control the flow rate of fluid in three stages: large, medium, and small.

Claims

[Scope of utility model registration request]

In the flow control valve, the flow control valve includes a main body that branches the valve flow passage into a bypass flow passage at a central portion of the flow passage through which fluid passes, and a plunger that is inserted into the main body from the side and opens and closes the valve flow passage. The valve flow passage is constituted by a first valve flow passage and a second valve flow passage arranged in parallel, and a coil spring is provided in which two types of shape memory alloys having different operating temperatures are connected in series. When the spring is energized and reaches a predetermined temperature, it expands and closes one or both of the first valve flow passage and the second valve flow passage to control the fluid flow rate in three stages: large, medium, and small. A flow control valve characterized by:
