Embodiment Construction

[0016] A conventional disk assembly for use with a fluid regulator includes a sealing disk positioned in a disk holder and partially retained in the disk sealing disk by a disk holder. When using such a conventional disc assembly, pressure may build up between the disc holder and the rear side of the sealing disc. If built up, this pressure has the potential to cause the sealing disc to slip and / or pop out of the disc holder. Different coefficients of thermal expansion between the disc holder and the disc holder may contribute to the build-up of pressure near the rear side of the sealing disc when conventional disc assemblies are subjected to extreme temperature changes. For example, when the disc holder and the disc holder expand and / or contract at different rates relative to each other in response to changes in temperature, fluid may potentially leak through and / or around the disc holder and disc holder. O-rings between the disc holders and are intended to provide a seal be...

Abstract

Mechanical retention sealing discs for use with fluid regulators are disclosed. In some examples, an apparatus includes a disk holder having an inner surface. In some examples, the apparatus includes a disk washer coupled to an inner surface of the disk holder. In some examples, the apparatus includes a sealed disk in the disk holder. In some examples, the sealing disc has a front side including a sealing surface and a back side positioned opposite the front side. In some examples, the rear side of the sealing disc is located adjacent the disc gasket. In some examples, the apparatus includes a disk holder coupled to the disk holder. In some examples, the disk holder retains the sealed disk in the disk holder.

Description

technical field [0001] The present disclosure relates generally to sealing disks and, more particularly, to mechanically retained sealing disks for use with fluid regulators. Background technique [0002] A conventional disk assembly for use with a fluid regulator includes a sealing disk positioned in a disk holder and partially retained therein by a disk holder. When using such a conventional disc assembly, pressure may build up between the disc holder and the rear side of the sealing disc. If built up, this pressure has the potential to cause the sealing disc to slip and / or pop out of the disc holder. Contents of the invention [0003] A mechanically retained sealing disc for use with a fluid regulator is disclosed. In some disclosed examples, an apparatus includes a disc holder having an inner surface. In certain disclosed examples, the apparatus includes a disk gasket coupled to an inner surface of the disk holder. In certain disclosed examples, the apparatus inclu...
