Title
(EN) VALVE BODIES HAVING INTEGRAL BOOST REDUCING CAPABILITY
(FR) CORPS DE VANNE À CAPACITÉ DE RÉDUCTION DE SURPRESSION INTÉGRÉE
Abstract
(EN)
Valve bodies having integral boost reducing capability are described herein. An example fluid regulator includes a body having a main passageway defining an orifice to fluidly couple an inlet and an outlet where the main passageway defines an inlet volume boundary between the inlet and the orifice and an outlet volume boundary between the orifice and the outlet. A portion of the outlet volume boundary includes an inner wall adjacent the orifice. A valve plug is disposed within the second portion of the passageway such that the inner wall substantially surrounds an outer surface of the valve plug to substantially restrict fluid flow between the inner wall and the outer surface of the valve plug and toward the throat. The valve body having a secondary fluid passage within the outlet volume boundary to increase fluid flow toward the throat of the valve body when a fluid flows across the orifice.

Des corps de vanne possédant une capacité de réduction de surpression intégrée sont décrits. Un régulateur de fluide cité à titre d'exemple comporte un corps possédant un passage principal définissant un orifice permettant le passage de fluide entre une entrée et une sortie, le passage principal définissant une limite de volume d'entrée entre l'entrée et l'orifice et une limite de volume de sortie entre l'orifice et la sortie. Une partie de la limite de volume de sortie comporte une paroi intérieure adjacente à l'orifice. Un opercule de vanne est prévu dans la deuxième partie du passage, de sorte que la paroi intérieure entoure sensiblement une surface extérieure dudit opercule pour réduire sensiblement le débit de fluide entre la paroi intérieure et la surface extérieure dudit opercule et en direction du col. Le corps de vanne possède un passage de fluide secondaire à l'intérieur de la limite de volume de sortie pour augmenter le débit de fluide en direction du col du corps de vanne lorsqu'un fluide s'écoule dans l'orifice.
