PNEUMATIC CONVEYOR FOR PREVENTING AIR FROM LEAKING

摘要

PURPOSE: A pneumatic conveyor for preventing air from leaking is provided to efficiently prevent air from leaking by a sealing body of which the outer diameter is expanded by pneumatic air and to use only for transferring air. CONSTITUTION: A pneumatic conveyor for preventing air from leaking is composed of a basic body(2) housing cargoes; caps(3,4) longitudinally installed on both sides of the basic body; sealing bodies(7) formed with body units(72) of flexible materials having circular arc-shape convex sections and the diameter size of a circle which is formed by the rim of the body units being smaller than the outer diameter of the caps, and wing units(74) extended from the rim of the body units to the outer diameter; and connecting rods(6) connecting the sealing bodies with the caps to contact the rim of the body units of the sealing bodies to at least one end of caps and sliding at a longitudinal direction of the basic body at a constant length.
