Element having ceramic insert and high-strength element-to-shaft connection for use in a valve |
摘要 |
An element for controlling the fluid flow rate through a fluid valve. The element may include a generally spherical metal housing encasing a cylindrical ceramic insert. The element may also include a cone-shaped metal housing encasing a cylindrical ceramic insert. The cylindrical ceramic insert defines a fluid passageway through the element. The element further includes a coupling mechanism disposed on the metal housing configured for securing a metal actuation shaft to the element. The coupling mechanism provides a high-strength element-to-shaft connection between the metal actuation shaft and a metal portion of the element. The present invention also encompasses a method of manufacturing the element.
