Abstract
A pressure control device can include an outlet, an inlet secured to well equipment, and a swivel mechanism that permits relative rotation between the outlet and the inlet in an unlocked configuration and prevents relative rotation between the outlet and the inlet in a locked configuration. A lock device of the swivel mechanism can include circumferentially distributed teeth, and an engagement member that engages at least one of the teeth in the locked configuration. A method of operating a pressure control device can include securing an inlet of the pressure control device to well equipment, rotating an outlet of the pressure control device about a longitudinal axis of the inlet, locking a swivel mechanism of the pressure control device, thereby preventing rotation of the outlet relative to the inlet, and sealing off an annulus surrounding a tubular string extending through the inlet.
