Embodiment Construction

[0017] Examples disclosed herein relate to fluid control devices that provide high shut-off performance over a wide temperature range (eg, -50°F to 200°F). Some fluid control devices include, for example, valves (eg, ball valves, butterfly valves, gate valves, etc.), fluid regulators, actuators, controllers, and the like. At warmer operating temperatures, the valve seats of these fluid control devices may become relatively soft, and at cooler operating temperatures, the valve seats of these fluid control devices may become relatively hard. Improved shutoff performance at lower temperatures can be obtained if the valve plug and / or ring have sharp engagement edges to engage the valve seat. However, at warmer operating temperatures, the seat becomes relatively soft, and this sharp engagement edge may cut or otherwise damage the seat, resulting in increased maintenance and / or reduced shutoff performance.

[0018] In accordance with the teachings of the present invention, the valv...

Abstract

Fluid control devices including self-healing materials and related methods are disclosed. An exemplary device includes a valve body, a seat ring, a valve plug movable relative to the seat ring to control fluid flow through the valve body, and a self-healing material on one of the valve plug or the seat ring. The self-healing material is designed to perform self-healing in the absence of external stimuli.

Description

[0001] related application [0002] This patent claims priority to US Provisional Patent Application No. 61 / 982,716, filed April 22, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to fluid control devices, and more particularly to fluid control devices including self-healing materials and related methods. Background technique [0004] The valve includes a valve plug that engages a valve seat to control fluid flow through the valve. Over time, the engagement between the plug and seat can cause damage to the seat. In some instances, the valve seat becomes relatively soft when the valve is operated at high temperature and relatively hard when the valve is operated at low temperature. Contents of the invention [0005] According to one aspect of the invention there is provided an apparatus comprising a seat ring for use with a fluid control device comprising a self-healing material. The self...
