Title:
PIPE JOINT FOR FLUID TRANSPORT PIPE
Document Type and Number:
Japanese Patent JPH09210271
Kind Code:
A
Abstract:

To suppress a damage from being caused at a connection part between a joint body and a connecting cylindrical part by an external force by providing a movable cylindrical body which is connected flexibly and air tight in three dimensional directions on a fixed cylindrical body formed integrally in a joint main body.

One end part 10A of a movable cylindrical body 10 in its axial Y direction is formed expandedly in the form partial sphere toward the radial outer direction so as to form a partially spherical sliding surface 10a which slides on a sliding surface 9a. Also the inner diameter of a fixed cylindrical body 9 is formed in one which allows the insertion and extraction of the movable cylindrical body 10 from its axial direction. Then a cast iron slide guide member 12 is arranged between an elastic seal material 11 and stopper member 13. Thus an extraction preventing means 14 to prevent, by contact, the extracting movement of the movable cylindrical body 10 from the fixed cylindrical body 9 while the bending of the movable cylindrical body 10 by the rotation of it along the sliding surfaces 9a, 10a, and 12a relative to the fixed cylindrical body 9 is formed with the slide guide member 12 and the stopper member 13.
