パツキング６を挾圧するようになつている。 The method for preventing water leakage in this case is to use a retaining flange 4 of a cap nut 2 that extends from the end edge of the supplementary pipe 1 and protrudes toward the outer circumference and is fitted on the outside of the supplementary pipe 1, and this flange. A protruding tube 5 is provided that is connected to the branch port 4 and protrudes in the extension direction of the supplementary pipe 1. First, the protruding tube 5 is fitted inside the branch port 3, and then the cap nut 2 is screwed into the branch port 3 to close the branch port. The end face of 3 and the flange 4 are adapted to clamp a packing 6 which has been previously fitted on the outside of the protruding cylinder 5.
継ぎ足しパイプの端に重なり合つた二重壁のフ
