Abstract: A pinch valve configured to be combined with an inversion apparatus. An elongated component, such as a rope, cable, or light train, is able to pass through the lumen of the pinch valve during the positioning and curing of a repair assembly into an underground pipe system. A deformable member positioned within the housing is movable between a first position having a first internal diameter and a second position having a second internal diameter that is smaller than the first internal diameter. In the second position the deformable member is moved to constrict around the elongated component as the component passes through the valve. This helps prevent pressure from escaping through the pinch valve by decreasing the space between the deformable member and the elongated component. In this manner, the internal diameter of the pinch valve is able to conform to various diameters of elongated components passing through the valve in real time by moving the deformable member to create the desired internal diameter.

Abstract: Disclosed fluid flow modifying devices are useful with flexible fluid flow conduits. Such devices are adapted for mitigating adverse flow considerations arising from one or more bends in flexible fluid flow conduits. These adverse flow considerations are generally characterized as enhanced laminar flow and associated increased backpressure arising from reduced flow velocity caused by the one or more bends. Beneficially, disclosed fluid flow modifying devices cause flow of flowable material (e.g., a liquid) within a flow passage of a fluid flow conduit to have a rotational flow profile. Such a rotational flow profile advantageously reduces frictional losses associated with laminar flow and with directional change of fluid flow.
