Claims

[Scope of utility model registration request]

The upstream exhaust pipe 30 and the downstream exhaust pipe 40 are arranged on the same axis so as to face each other with a slight gap So left at the end of the pipe. , a truncated spherical sealing material 20 having a convex spherical surface portion 21 on its outer peripheral surface is inserted into the central through holes 24, 25, 27, 28 along the center line.
28, and the end face of the sealing material 20 is fitted into a flange 50 fixed to the outer peripheral surface of one exhaust pipe 30.
A concave spherical seal seat 60 corresponding to the outer circumferential convex spherical surface portion 21 of the sealing material 20 is provided at the pipe end of the other exhaust pipe 40, so that both exhaust pipes 30 and 34 are sealed. In a spherical pipe joint that is connected so as to be relatively movable by a pressing means such as a pressing spring 90 via a material 20,
The inner surface of the center through hole 24, 25, 28 of the sealing material 20,
A spherical pipe joint in which one of the outer circumferential surfaces of one exhaust pipe 30 is formed into a truncated conical shape, and both are seated with an interference margin.
