Claims

[Scope of utility model registration request]

A valve housing 1 having a pressure inlet 6 and a pressure release port 7 includes a valve body 2 having a pressure receiving surface 21 facing the inlet 6, and a valve body 2 that acts on the back surface 22 of the valve body 2. A safety valve device is provided with an elastic body 3 for setting an operating pressure, and the introduction port 6 is made to communicate with the opening port 7 by the operation of the valve body 2,
The valve housing 1 is provided with a cylinder portion 10 having an inner surface facing the outer surface of the valve body 2 and communicating with the introduction port 6 on one side and the opening port 7 on the other side, and the inner surface of the cylinder portion 10 and The valve body 2
A seal body 4 is interposed between the outer surface of the cylinder portion 10 and the valve body to divide the inside of the cylinder portion 10 into a primary chamber 11 communicating with the introduction port 6 and a secondary chamber 12 communicating with the opening port 7. 2, when the valve body 2 is actuated, a communication passage 5 passes over the seal body 4 with a predetermined stroke and communicates the primary chamber 11 with the secondary chamber 12;
A safety valve device characterized in that:
