Abstract

Una válvula deslizante tiene un cuerpo de válvula, un manguito deslizante recibido en un orificio longitudinal del cuerpo de la válvula y un collar que se puede recibir en un orificio longitudinal del manguito deslizante. El cuerpo de la válvula tiene uno o más puertos de fluido en una porción de boca de pozo de la pared lateral del mismo. El manguito deslizante es móvil entre una posición cerrada de boca de pozo que cierra uno o más puertos de fluido y una posición abierta de fondo de pozo que abre uno o más puertos de fluido. El collar comprende una porción de metal alrededor de un extremo de boca de pozo del collar, y un asiento de bola que tiene una superficie de asiento de bola inclinada radialmente hacia adentro desde la boca del pozo hasta el fondo del pozo en un ángulo de pendiente agudo con respecto a un eje longitudinal del collar. La porción metálica se puede expandir radialmente hacia afuera bajo una presión radialmente hacia afuera para formar un sello de metal a metal en la interfaz entre el collar y el manguito deslizante cuando el collar se recibe en el manguito deslizante.A slide valve has a valve body, a slide sleeve received in a longitudinal hole of the valve body, and a collar that can be received in a longitudinal hole of the slide sleeve. The valve body has one or more fluid ports in a wellhead portion of the side wall thereof. The sliding sleeve is movable between a closed wellhead position that closes one or more fluid ports and an open downhole position that opens one or more fluid ports. The collar comprises a metal portion around a wellhead end of the collar, and a ball seat having a ball seat surface inclined radially inward from the wellhead to the bottom of the well at a sloping angle. acute with respect to a longitudinal axis of the collar. The metal portion can expand radially outward under radially outward pressure to form a metal-to-metal seal at the interface between the collar and the sliding sleeve when the collar is received in the sliding sleeve.
