Abstract
The utility model relates to the related technical field of pneumatic conveying, in particular to a high-sealing-performance pneumatic conveying inner wall air groove steel pipe which comprises a first steel pipe and a second steel pipe, the first steel pipe is a straight pipe, the second steel pipe is a straight pipe with an elbow, and a positioning thread groove is formed in the inner wall of the second steel pipe. Two arc-shaped grooves are formed in the surface of each of the first steel pipe and the second steel pipe, and a sealing assembly is fixedly connected between the first steel pipe and the second steel pipe. According to the high-sealing-performance pneumatic conveying inner wall air groove steel pipe, through the arrangement of the sealing assembly, when the high-sealing-performance pneumatic conveying inner wall air groove steel pipe is used, extrusion grooves in the inner walls of an upper arc-shaped plate and a lower arc-shaped plate can be matched with arc-shaped grooves to extrude a rubber sealing ring and an annular air bag ring, and the effect of deformation of the rubber sealing ring and expansion of the annular air bag ring is utilized; the air tightness between the first steel pipe and the second steel pipe is improved, it can be guaranteed that the negative pressure in the pipeline does not change in the pneumatic conveying process, and therefore the stability of pneumatic conveying is guaranteed.
