The present invention relates to a vacuum relief valve. More specifically, when a vacuum disc is lifted by a vacuum pressure inside a storage tank where various types of fluids are stored, a valve body where the vacuum disc is stored is installed with an instrument to prevent oscillation, so as to prevent the vacuum disc from oscillating. Thereby, when the vacuum disc opens the mouth of the valve body, the vacuum disc is prevented from oscillating so as to prevent collisions between the metals. Due to this, a spark caused by the collisions between the metals can be fundamentally avoided in order to prevent an explosive accident. |
