The utility model discloses an air inlet device of a
safety valve, which relates to the field of safety valves, solves the problem that the existing device is difficult to disassemble and assemble conveniently and maintain components according to requirements, and adopts the following scheme that the air inlet device comprises an air inlet
pipe mounted on a container and a valve body assembled at the end of the air inlet
pipe, and a sealing component is mounted between the air inlet
pipe and the valve body in a pressing manner; a supporting clamp is fixedly welded to the edge of the outer end of the air inlet pipe, an end ring is arranged at the bottom end of the valve body, a clamping sleeve is fixedly welded to the outer wall of the edge of the bottom side of the end ring, and the valve body is clamped to the supporting clamp on the top side of the air inlet pipe through the clamping sleeve. According to the air inlet device of the
safety valve, the air inlet pipe and the valve body are conveniently assembled in a rotary clamping mode, the sealing
assembly is arranged between the air inlet pipe and the valve body, the sealing
assembly can be deformed by means of press fitting, a gap between the sealing
assembly is filled with the sealing assembly, and therefore the sealing effect is guaranteed; and meanwhile, disassembly and maintenance of components on the inner side are facilitated.
