Title
(EN) FRONT LOADED SEAT SEAL
(FR) JOINT DE SIÈGE À CHARGEMENT FRONTAL
Abstract
(EN)
A flow control device includes a valve body, a first port disposed on the valve body, a second port disposed on the valve body, a gate disposed within the valve body and configured to control a flow of a fluid between the first port and the second port, and a seat disposed between the gate and the valve body, the seat including a first surface configured to form a circumferential seal with the valve body and a second surface configured to form a face seal with the gate. A method includes receiving, by a sealing assembly forming a circumferential seal between a seat and a valve body, a first force from a collar disposed on the seat in response to a first movement of a gate, and moving, in response to receiving the first force, the sealing assembly in a first direction of the first force.
(FR)
L'invention concerne un dispositif de régulation de débit comprenant un corps de vanne, un premier orifice disposé sur le corps de vanne, un second orifice disposé sur le corps de vanne, une porte disposée à l'intérieur du corps de vanne et conçue pour réguler un écoulement d'un fluide entre le premier orifice et le second orifice, et un siège disposé entre la porte et le corps de vanne, le siège comprenant une première face conçue pour former un joint circonférentiel avec le corps de vanne et une seconde face conçue pour former un joint facial avec la porte. Un procédé consiste à recevoir, au moyen d'un ensemble d'étanchéité formant un joint circonférentiel entre un siège et un corps de vanne, une première force en provenance d'un collier disposé sur le siège en réponse à un premier mouvement d'une porte, et à déplacer, en réponse à la réception de la première force, l'ensemble d'étanchéité dans une première direction de la première force.
