Abstract
A valve used in combination with a vessel containing fluid in the interior and a parameter measuring device. The valve allows the device to be exposed to the fluid in the interior of the vessel. The device may be installed into the valve, and the valve may be fitted to the side of the vessel. The valve improves upon other prior art by providing provisions for purging air trapped in the internal cavity of the valve. The valve includes a purge position, which provides a smaller opening from the interior of the vessel to the internal cavity and an air path to the external atmosphere. Fluid may fill the valve pushing trapped air out of the valve until the majority of the trapped air is expelled.
Claims19
A valve configured for use in combination with a vessel defining an interior, comprising:
- an outer sleeve configured for engagement with a wall of the vessel and to extend into the vessel interior, wherein the outer sleeve includes a wall that defines an internal cavity, wherein the wall is provided with one or more openings;
- an inner sleeve movably engaged with the outer sleeve and having a portion positioned within the internal cavity of the outer sleeve, wherein the inner sleeve defines an interior and includes one or more openings that establish communication between the internal cavity of the outer sleeve and an interior defined by the inner sleeve, wherein the interior defined by the inner sleeve is configured to receive a component such as a sensor, and wherein the inner sleeve further includes an external portion located externally of the vessel wall, wherein the external portion of the inner sleeve is provided with a passage that communicates between the interior of the inner sleeve and the exterior of the vessel;
- wherein the inner sleeve is movable relative to the outer sleeve between a closed position, wherein the openings of the inner sleeve are positioned out of alignment with the openings of the wall of the outer sleeve so as to cut off communication between the vessel interior and the interior of the inner sleeve, and a purge position at initial installation of the component or subsequent to replacement of the component, wherein communication is established between the vessel interior and the interior of the inner sleeve wherein, in the purge position, the passage in the external portion of the inner sleeve can be opened so as to enable fluid to pass from the vessel interior into and through the interior of the inner sleeve and through the passage so as to expel any air that may be contained within the internal cavity of the outer sleeve and the interior of the inner sleeve;
- wherein the passage and the external portion of the inner sleeve can be opened via operation of a plug member by a user to selectively move the plug member relative to the passage between a closed position and an open position.

A valve configured for use in combination with a vessel defining an interior, comprising:
- an outer sleeve configured for engagement with a wall of a vessel, wherein the outer sleeve includes a first wall that defines a first internal cavity, wherein the first wall includes one or more openings, wherein a portion of the first wall and the one or more openings of the outer sleeve extend into the interior of the vessel;
- an inner sleeve configured for engagement with the first internal cavity of the outer sleeve, wherein the inner sleeve includes a second wall that defines a second internal cavity, wherein the second wall includes one or more openings, wherein a portion of the second wall and the and the one or more openings of the inner sleeve extend into the first internal cavity of the outer sleeve;
- wherein the inner sleeve further includes a passage that establishes communication between the second internal cavity and an exterior of the vessel, wherein the passage is configured to be opened and closed;
- wherein the inner sleeve is moveable relative to the outer sleeve such that moving the inner sleeve changes the valve between an open position, a closed position, and a purge position;
- wherein, in the open position, the one or more openings of the outer sleeve are aligned with the one or more openings of the inner sleeve such that the interior of the vessel is in communication with the second internal cavity of the inner sleeve, wherein the passage is closed to cut off communication between the second internal cavity of the inner sleeve and the exterior of the vessel;
- wherein, in the closed position, the one or more openings of the outer sleeve are not aligned with the one or more openings of the inner sleeve such that the interior of the vessel is not in communication with the second internal cavity of the inner sleeve;
- and wherein in the purge position, the one or more openings of the outer sleeve are at least partially aligned with the one or more openings of the inner sleeve such that the interior of the vessel is in communication with the second internal cavity of the inner sleeve, wherein the passage is open such that the second internal cavity of the inner sleeve can be placed in communication with the exterior of the vessel via operation of a plug member by a user to selectively move the plug member relative to the passage between a closed position and an open position.
4 more elements
A method of installing a device in a vessel having an exterior and an interior within which a volume of fluid is contained, comprising the acts of:
- providing a valve interconnected with the wall of the vessel, wherein the valve defines an internal cavity configured to receive the device, wherein the valve is configured such that the internal cavity of the valve may selectively communicate both with the interior of the vessel and with the exterior of the vessel;
- positioning the valve in a closed position in which communication between the internal cavity of the valve and the exterior of the vessel is established and communication between the internal cavity of the valve and the interior of the vessel is cut off;
- installing the device in the internal cavity of the valve while the valve is in the closed position via mating engagement structure associated with the device and with the valve, wherein installation of the device cuts off communication between the internal cavity of the valve and the exterior of the vessel;
- and purging the internal cavity of the valve by selectively establishing communication between the interior of the vessel and the exterior of the vessel through the valve during movement of the valve away from the closed position toward an open position, wherein in the open position the valve establishes communication between the internal cavity of the valve and the interior of the vessel and cuts off communication between the internal cavity of the valve and the exterior of the vessel.
