Methods and apparatus to access and align sealing discs

摘要

Methods and apparatus to access and align sealing discs are disclosed herein. An example apparatus includes a cage of a fluid regulator, where the cage has a central aperture, and a valve stem to be received by the central aperture. The example apparatus also includes a diaphragm coupled to the valve stem, where an integral protrusion of the cage is to constrain a peripheral edge of the diaphragm against a removable portion of a valve body when the cage is coupled to the valve body.

1. An apparatus comprising:
a cage of a fluid regulator, the cage having a central aperture; a valve stem to be received by the central aperture; and a diaphragm coupled to the valve stem, wherein an integral protrusion of the cage is to constrain a peripheral edge of the diaphragm against a removable portion of a valve body when the removable portion is coupled to the valve body, wherein the removable portion of the valve body at least partially defines an outer surface of the valve body, the cage further comprising a threaded portion to receive a valve stem guide to align the valve stem.
