摘要： A nozzle design and method for designing such a nozzle being adapted for three phase slurry flow from the choke into the flash tank during pressure let-down in autoclave mining operations that uses a selection of the expansion ratio in the choke to select a nozzle dispersion angle to select a spread of the flow over the slurry pool in the flash tank, to generally maximize the use of the pool for energy dissipation without causing undo wear and tear on the tank walls.

摘要： As set forth in the detailed description, the present invention includes, in various exemplary embodiments, a valve device to control fluid flow that incorporates a substantially flat plug head. By incorporating a substantially flat plug head, the valve device realizes lower stresses than other typical valve configurations; namely thermal and tensile stress is reduced throughout the valve device. In an exemplary embodiment of this invention, the valve device comprises a housing, at least one plug head seat within the housing, a substantially planar or flat plug head configured to control or stop flow of a substance and a plug stem configured to actuate the substantially flat plug head. In accordance with one exemplary embodiment, the substantially flat plug head comprises a solid disk shaped or cylindrical shaped plug head. Additionally, in one exemplary embodiment, the plug head and plug head seat material can comprise ceramics and various metal alloys.
