Abstract
Abstract A valve made as a hybrid valve partially from standard shapes of exotic metals which will withstand corrosive chemicals and partially from castings, or as a casting from a corrosionresistant material, and which includes an elliptical valve hole that forms a valve seat that is contained in a plate that is inclined to the flow of fluid through the valve. The valve further includes a solid tapered or conical plug that closes off flow by entering the elliptical hole, and seating therein, along an axis perpendicular to the axis of fluid flow through the valve.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
281 words
In a valve, the combination comprising: a. a valve body having an inlet passage and an outlet passage; b. a valve plate mounted between said inlet and outlet passages and being inclined at an angle nonperpendicular to the longitudinal axes of said inlet and outlet passages; c. said valve plate being provided with an opening therethrough to communicate said inlet passage with said outlet passage and to form a valve seat; d. a plug valve mounted in said valve body and being linearly movable along and free to rotate about an axis perpendicular to the longitudinal axes of said inlet and outlet passages; e. means for linearly moving said plug valve to an open position to permit fluid to flow from the inlet passage through the opening in the valve plate and into said outlet passage, and for linearly moving the plug valve into the valve opening in the valve plate to a closed position to block flow between said inlet and outlet passages; f. said opening through said valve plate being elliptical when viewed from the inlet and outlet passages along the longitudinal axes thereof so as to provide an elliptical valve seat; g. said plug valve being conically shaped and rotatable by continued openings and closings so as to provide an infinite number of seating surfaces for seating engagement on said elliptical valve seat; h. said plug valve being carried on an internally threaded tubular shaft; and, i. said means for linearly moving the plug valve including a rotatable threaded stem operatively mounted on said valve body and having one end thereof threadably engaged with said tubular shaft and provided on the other end thereof with a hand wheel.
