Embodiment Construction

[0022] Typically, fluid regulators regulate the flow of fluid based on sensed downstream pressure to maintain process system pressure within an acceptable and / or stable pressure range. Fluid regulators typically include a diaphragm operably coupled to a valve plug via a connecting mechanism (eg, a lever) for moving the valve plug relative to a valve seat to prevent or allow flow of fluid between an inlet and an outlet. Fluid regulators typically use a preset control force or load applied to a first side of a diaphragm to push a valve plug in a first direction to regulate flow and pressure of a process fluid. The second side of the diaphragm is fluidly coupled to the outlet fluid to apply a force to urge the diaphragm in a second direction opposite the first direction. Thus, the diaphragm moves in response to the difference between the pressure of the fluid at the outlet (i.e., the force applied to the second side of the diaphragm) and a preset control force (i.e., the force ap...

Abstract

An example loading regulator having an internal relief valve apparatus includes a body having a loading diaphragm disposed between a first casing and a second casing. The first casing and a first side of the loading diaphragm define a first chamber and the second casing and a second side of the loading diaphragm define a second chamber. A relief valve assembly is coupled to the loading diaphragm. The relief valve assembly includes a relief valve seat having an aperture that forms a passageway to fluidly couple the first chamber and the second chamber and a relief valve plug movably coupled to the relief valve seat. The relief valve plug is to move away from the relief valve seat to a bleed position to allow the flow of fluid between the first chamber and the second chamber in response to an outlet pressure substantially greater than a pressure at which the loading regulator enters a lock-up condition.

Description

technical field [0001] The present disclosure relates generally to fluid regulators and, more particularly, to internal relief valve arrangements for use with load regulators. Background technique [0002] Process control systems utilize various field devices to control process parameters. Fluid regulators are typically distributed throughout process control systems to control the pressure of various fluids (eg, liquids, gases, etc.). Fluid regulators are commonly used to regulate the pressure of a fluid to a lower and / or substantially stable value. Specifically, a fluid regulator has an inlet that typically receives a supply fluid at a relatively high pressure, and the fluid regulator provides a relatively low and / or substantially constant pressure at the outlet. [0003] As a high pressure process fluid passes through a process control system, a regulator reduces the pressure of the process fluid at one or more points to supply the process fluid at a lower or reduced pre...
