Abstract

A valve to open communications between the ID and OD of a tubular member by rotating an inner sleeve to align one or more slots between an inner sleeve and an outer sleeve. The advantage to this type of design is, when opening the valve under pressure, the initial surge of pressure is minimized because of the small inlet area of the slots.

Rotating Insert Valve

Abstract

A valve to open communications between the ID and OD of a tubular member by rotating an inner sleeve to align one or more slots between an inner sleeve and an outer sleeve. The advantage to this type of design is, when opening the valve under pressure, the initial surge of pressure is minimized because of the small inlet area of the slots.

Description of the Invention

The valve includes an outer sleeve with slots and an inner sleeve with the same number of slots. The slots in the inner sleeve are surrounded by a seal member, either as a separate part (such as an o-ring) or an elastomer bonded to the inner sleeve. The inner sleeve is inserted in the ID of the outer sleeve with the slots linearly aligned. As the inner sleeve is rotated, the slots in the inner sleeve will either be aligned with the slots in the outer sleeve (valve open) or the slots in the inner sleeve will be blocked by the material between the slots of the outer sleeve (valve closed). In the "valve closed" position the seal members on the inner sleeve will surround the slots in the outer sleeve thus sealing communication. The inner sleeve to the outer sleeve rotational alignment would be indexed so that in the open position the slots in both sleeves will be aligned and in the closed position the sealing member around the slots in the inner sleeve slots will surround the slots in the outer sleeve.
