。 A valve surface 5 is formed around the inlet hole 4 on one side of the valve chamber 3 in the valve body 2 of the safety valve 1, and the valve body 6 provided in the valve chamber 3 is connected to the valve closing tension of a spring 7 made of a shape memory alloy. When the valve is in contact with the valve face 5 for closing and the ambient temperature of the valve body 2 is higher than the set temperature for safe operation, the spring 7 is deformed into the valve opening shape due to shape memory action, and its closing tension is reduced. In a temperature-sensitive valve opening type safety valve configured such that pressure fluid opens the valve body 6 and escapes to the outside through the inlet hole 4 and the valve chamber 3 when the pressure fluid decreases or disappears, the valve body 6 is composed of a ball valve body, the valve surface 5 is formed in a concave shape centered on the inlet hole 4, and the shape memory alloy type spring 7 is composed of a plate spring,
The plate spring 7 is arranged transversely in a space on the opposite side of the valve surface 5 with the ball body 6 as the center, and the transverse intermediate portion 8 of the plate spring 7 is brought into contact with the ball valve body 6 from the back side. This temperature-sensitive valve opening type safety valve is characterized in that its edge portion 10 is fixed to the valve body 2.
