Pipe expansion and contraction compensation connection structure for high-tech ship

Abstract

The application relates to a high-tech ship in the field of high-end equipment manufacturing technology, and discloses a pipe expansion and contraction compensation connecting structure for the high-tech ship, which is characterized in that the opposite ends of pipe fittings of the pipe are respectively provided with joint shoulders, two inner sealing ring ring seats are installed between the two joint shoulders, and an inner sealing compression spring is clamped between the two inner sealing ring ring seats; the diameters of two holes in the inner hole of a pipe half joint on the left and right of the two pipe fittings respectively correspond to the outer diameter of the joint shoulder and the outer diameter of the pipe wall of the pipe fitting; two outer sealing ring ring seats are arranged between the outer side of the joint shoulder and the side surface of the corresponding pipe half joint stepped hole, and an outer sealing compression spring is clamped between the two outer sealing ring ring seats; a sealing ring is arranged between the inner and outer sides of the joint shoulder and the inner and outer sealing ring ring seats; and a sealing ring is arranged between the inner hole of the pipe half joint and the outer periphery of the joint shoulder and the outer periphery of the inner and outer sealing ring ring seats on the two sides. The application can realize the welding-free connection between the pipe fittings and compensate the length change of the pipe fittings.
