Abstract:
A valve comprising:a valve body having a flow bore, an inlet port, and an outlet port, the outlet port disposed in a substantially perpendicular relationship relative to the inlet port, the valve body having a substantially frusto-conically shaped interior surface defining the flow bore and a barrel stop plate extending radially inward and contiguous with the inlet port of the valve body;a barrel disposed within the flow bore of the valve body, the barrel having an inlet, an outlet, and a fluid flow passageway extending between the inlet and the outlet, the inlet of the barrel concentrically positioned relative to the inlet port of the valve body and the outlet of the barrel disposed in a substantially perpendicular relationship relative to the inlet of the barrel, the barrel having a substantially frusto-conically shaped exterior surface and the barrel movable between a locked position wherein the frusto-conically shaped exterior surface of the barrel is sealingly engaged against the frusto-conically shaped interior surface of the valve body and an unlocked position wherein the barrel is in a non-sealing engaging relationship relative to the valve body, the barrel having a seal member which sealingly engages the barrel stop plate when the barrel is in the locked position, the barrel further movable in the unlocked position between a closed position wherein the outlet of the barrel is aligned with the interior surface of the valve body and an open position wherein at least a portion of the outlet of the barrel is open communication with the outlet port of the valve body; andactuating means connected to the barrel for axially moving the barrel relative to the valve body between the locked position and the unlocked position and for rotating the barrel between the open position and the closed position when the barrel is in the unlocked position.
