Abstract
A valve body having a ring of dissimilar material and a method of forming the valve body are described. The valve body includes an inlet, an outlet and a ring of dissimilar material. The method includes forming a valve core, splitting the valve core, placing a metal ring of dissimilar material between two pieces of the valve core, casting a valve body around the valve core, and fusing the metal ring to the valve body.
Claims13
A valve body comprising:
- a fluid inlet and a fluid outlet connected by a fluid passageway, the fluid inlet extending along an inlet axis, and the fluid outlet extending along an outlet axis;
- and
- a metal ring of dissimilar material fused to the valve body in the fluid passageway, the metal ring centered about a longitudinal axis that is substantially perpendicular to the inlet axis and to the outlet axis,
- wherein the metal ring comprises a bonding structure configured to enhance fusing of the metal ring to the valve body,
- wherein the bonding structure is entirely enveloped by the valve body, and
- wherein the bonding structure comprises:
- an annular shelf extending radially outward from the metal ring in a direction substantially parallel to the inlet axis;
- and
- a wall that extends radially outward from the annular shelf in a direction substantially parallel to the longitudinal axis, such that the wall is oriented substantially perpendicular to the annular shelf.

A valve body comprising:
- a fluid inlet and a fluid outlet connected by a fluid passageway, the fluid inlet extending along an inlet axis, and the fluid outlet extending along an outlet axis;
- a valve port disposed in the fluid passageway;
- and
- a metal ring of dissimilar material fused to the valve body in the valve port, the metal ring centered about a longitudinal axis that is substantially perpendicular to the inlet axis and to the outlet axis,
- wherein the metal ring comprises a bonding structure configured to enhance fusing of the metal ring to the valve body,
- wherein the bonding structure is entirely enveloped by the valve body, and
- wherein the bonding structure comprises a single cone-shaped band extending outward from the metal ring, away from the valve port, wherein the metal ring has an outer surface that extends in a direction substantially parallel to the longitudinal axis, and wherein the bonding structure extends outward from a portion of the outer surface that is located between a first end of the metal ring and a second end of the metal ring, such that the bonding structure is spaced from both the first end of the metal ring and the second end of the metal ring.
