Claims

[Scope of utility model registration request]

Inside the joint pipe type case with male threads machined on both ends of the outer periphery, there are a fluid inlet into which fluid flows, a valve chamber into which the fluid at the inlet flows in through a valve port, and a fluid outlet through which the fluid in the valve chamber flows out. A valve seat is formed in the opening part of the valve chamber side of the valve port, and the valve chamber of the valve port is formed so that the valve body seats on the valve seat and closes the valve port, and moves away from the valve seat to open the valve port. A valve body is placed on the side, a valve stem is integrally machined with the valve body, and a movable support member is attached to the valve body side portion of the valve body as a guide for linear movement of the valve stem toward the valve seat. Move along the inner circumferential wall, attach a fixed support member to the outlet side part of the valve chamber, provide a valve stem guide hole in the center, fit the lower end of the valve stem into the guide hole, and heat the valve stem at 100°C. Both ends of the temperature-responsive element made into a coil shape using the shape-memory alloy that transforms are fixed to both the movable support member and the fixed support member, and the temperature-responsive element responds to the temperature of the fluid in the valve chamber. A temperature-responsive valve characterized by a structure that transforms and drives a valve body, and when the temperature exceeds a predetermined temperature, the valve body is seated on or separated from a valve seat to open and close a valve port.
