A low-pressure large-diameter safety valve

The invention relates to a safety valve for performing overpressure protection on a pressure system, in particular to a low-pressure large-diameter spring direct-action type safety valve. A guiding sleeve is connected between a valve body and a cover plate; a bonnet is arranged on the cover plate; a positioning screw is connected to a side hole of the valve body in a valve body cavity; the valve body is connected with an adjusting ring; an O-shaped ring is inlaid in a groove formed by a valve clack and a disc holder and is fixed at the lower end of a body of the disc holder, and a formed combination is pressed on a sealing surface of the valve body through a spring; a spring and an upper spring seat are integrally positioned in a cavity formed by the disc holder, the guiding sleeve and the cover plate; the spring is directly arranged on the disc holder; an adjusting screw is arranged on the cover plate; a locking nut is arranged at the upper end of the adjusting screw; the adjusting screw conducts force to the spring through a thrust washer, a bearing and the upper spring seat, and setting pressure is adjusted; the disc holder and the sealing surface of the valve body are ground and then are in metal sealing; and the O-shaped ring and the sealing surface of the valve body are in nonmetal elastic sealing.
