<p>The present invention is related to a safety relief valve for preventing debris seating with a double disc and a sheet. For configuring the relief valve including the sheet and the double disc, the sheet comprises a sheet sealing unit to be formed in a triangle shape, wherein an inner side sheet contact surface is formed in an inclined surface and an outer side sheet contact surface is formed in a flat surface. The double disc comprises a disc sealing unit formed in a groove shape of the triangle shape and a structure of the inclined inner side sheet contact surface and the flat outer side sheet contact surface. When the valve is opened, debris is not seated and discharged to the outside with a working medium. And it is possible to fundamentally prevent the damage to the double disc and the sheet which may occur due to the debris.</p> |
