Abstract

A plug head assembly having a ceramic plug head having an annular retention groove, wherein the ceramic plug head has a proximal terminus and a distal terminus, a first clamp portion having a first annular retention protrusion conforming to the annular retention groove, a second clamp portion having a second annular retention protrusion conforming to the annular retention groove, and an annular retention sleeve conforming to the annular retention groove, the annular retention sleeve disposed between the annular retention groove and at least one of the first clamp portion and the second clamp portion.

Description

Background technique [0001] In the valve assembly, fluid flow is controlled by actuating the plug head assembly against the valve seat. In extreme operating environments (eg, under elevated temperature, pressure, and / or corrosive or abrasive fluids), components of the plug tip assembly may weaken or become more loosely coupled than expected. For example, where a ceramic plug is held by a conventional retainer, the retainer may expand at a higher rate than the ceramic plug, thereby loosening the fit between the retainer and the ceramic plug. In addition, thermal events and solids left by shattering may cause the ceramic plug to crack, which may then separate from the plug assembly or compromise the integrity of the plug ceramic. [0002] Ceramic plugs, such as those comprising sintered silicon carbide (SSiC), are often used in extreme operating environments, such as high temperature applications (e.g., from about 20°C to about 260°C) and / or high pressure applications (e.g., fr...
