Abstract

PURPOSE: To improve certainty of seal by constituting the valve body of a safety valve from cylindrical ring which is resiliently deformable and is fixed onto the valve body so that the center shaft is fixed so as to be parallel to the direction of shift of the valve body and from a protecting ring.
CONSTITUTION: A safety valve is equipped with a valve body 1 which is pressed to an annular valve seat by a pressing element such as spring. The valve body 1 is equipped with a cylindrical ring 8 and a protecting ring 3, and the cylindrical ring 8 is formed integrally with the valve body 1 so that the center shaft of the cylindrical ring 8 is parallel in the direction of shift of the valve body 8. The upper part of the cylindrical ring is bent outside, and the egde of the bent part is fixed onto the valve body 1, and is made from the meterial which gas resilience and easier to deform than the protecting ring 3. When the pressure is zero, the sealing surface 4 is cotacted with the valve seat 2 due to the resilience of its own, and when the pressure in the valve seat port becomes larger, the sealing surface 4 is closely contacted with the valve seat 2 due to the pressure which operates to the pressure receiving surface 10.
