Claims

[Scope of utility model registration request]

(1) In a flexible pipe joint for connecting a conduit through which pressurized fluid passes, a flexible pipe joint is arranged between a pair of rigid rings spaced apart and mutually opposing surfaces of the pair of rigid rings. an annular flexible member, the flexible member being fluid-tightly adhered to the mutually opposing surfaces of each of the rigid rings, and the flexible member being exposed radially outward; and an annular inner sleeve surface exposed radially inward, the inner surface of which is in contact with the pressurized fluid, and the flexible member includes an integral elastomer. Ori,
The thickness between the pair of rigid rings integral with the elastomer decreases from the inner surface to the outer surface when measured in a direction substantially perpendicular to at least one of the mutually opposing surfaces of the pair of rigid rings. and the elastomer body maintains a shape in which the thickness decreases along a surface extending from the inner surface to the outer surface of the visibility member, so that when pressure is applied to the inner surface, The elastomer body is restrained from shifting from between the pair of rigid rings, and the flexible member has a plurality of elastomer bodies formed of a material with almost no extensibility within the elastomer body of the flexible member. annular inserts are embedded at spaced intervals, and the thickness of the last member does not include the thickness of the inserts, and the thickness of each insert is equal to or greater than the inner surface of the flexible member. A pipe joint that is characterized by becoming smaller towards the outside.

(2) The insert and the elastomer together form an annular shape in one plane, and form an arc in a plane perpendicular to the one plane, as described in claim 1 of the utility model registration claim. pipe joint.

(3) The pipe joint according to claim 2, wherein the arc of the insert is a circular arc.

(4) The pipe joint according to claim 3, wherein the insert and the elastomer are integrally formed into a spherical annular body.
