    摘要: The problem of flappers that will not close due to high velocity gas rushing past and creating a vortex that has zones of high pressure pressing the flapper against the force of the torsion spring is reduced or overcome with modifications in the passage through a subsurface safety valve so as to reduce the intensity of the vortex to allow the torsion spring to pivot the flapper to closed position. Various shapes are inserted adjacent the flapper base to create turbulence to minimize or prevent the vortex and the associated pressure increases that would otherwise prevent flapper closure with the flow tube retracted. Inserts that create turbulence are placed in a recess that in part holds the flapper when it is rotated to the open position.

    摘要: A flapper base provides a flapper base body with a hinge portion unitarily formed thereupon and a flapper seat surface formed within the flowbore of the body. The flapper base may be formed from a single section of tubular metallic stock. In a method of forming a base, the stock is gripped by a rotary clamp, and a five-axis milling machine is used to cut away portions of the stock section and to form the seat surface.

    摘要: A method of determining the position of a valve includes, measuring pressure at a first location within a bore and measuring pressure at a second location within the bore wherein the first location and the second location are positioned on opposing longitudinal sides of the valve. The method further includes analyzing values from the measuring and attributing characteristics of the analyzing to specific valve positions.
