Title (EN) BI-METAL VALVE BODY CASTING AND METHOD OF MAKING SAME
(FR) COULÉE DE CORPS DE SOUPAPE BIMÉTALLIQUE ET PROCÉDÉ DE FABRICATION DUDIT CORPS DE SOUPAPE
Abstract:
(EN) 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.
(FR) L'invention concerne un corps de soupape présentant une bague de matériau différent et un procédé de formation du corps de soupape. Le corps de soupape comprend une entrée, une sortie et une bague de matériau différent. Le procédé comprend la formation d'un noyau de soupape, la division du noyau de soupape, la mise en place d'une bague métallique de matériau différent entre deux pièces du noyau de soupape, la coulée d'un corps de soupape autour du noyau de soupape et la fusion de la bague métallique au corps de soupape.
