PURPOSE:To seal water, air, and sound positively, by installing a seal ring, which comprises a projection adhered to a partition plate, and a pipe adhesion member adhered to an external periphery of refrigerant piping, and an edge protection member adhered to an internal periphery of a pipe penetration hole, and fixing this seal ring to the partition plate. CONSTITUTION:After a stopper 26 for a fixing metal fitting 25 is placed to a receiving section 27 of a seal ring 20, the stopper 26 is compressed toward a partition plate 10 by fastening a screw 28 into a threaded hole bored on said partition plate 10. The receiving section 27 is also compressed in proportion to the movement of the stopper. At the same time, a recessed part 21 is also compressed so that a pipe adhesion section 22 is inwardly expanded and pressed into contact with refrigerant piping 12. Under the state where the screw 28 is further fastened and a fixing piece 29 is brought into contact with the partition plate 10, a projection 24 is pressed against the partition plate 10. In this manner, the portion between the outer periphery section of the refrigerant piping 13 and a pipe penetration hole 19 is firmly sealed by sealing the portion between the pipe adhesion section 22 and the refrigerant piping 13, and the projection 24 of the seal ring 20, thereby enhancing the sealing capacity against water, air, and sound definitely and easily. |
