摘要： The automatic valve comprises a valve seat (52) with first gas flow passages (58) extending there through, and a valve guard (54) having second gas flow passages (66) extending there through. Sealing rings (60) are arranged between the valve guard and the valve seat. A removable seat plate (68) is removably connected to the valve seat (52) and is provided with apertures (70) matching with the first gas flow passages (58) of the valve seat. The sealing rings are resiliently biased by resilient members (62) against the removable seat plate (68) to close the valve. The seat plate and the rings are made of non-metallic material.

摘要： Impellers made of composite materials with flow path cavities covered by an erosion resistant coating are manufactured by covering removable molds having shapes corresponding to a negative geometry of the flow path cavities, with the erosion resistant coating using plating or thermal spraying. After shaping and curing a composite material around the molds covered with the erosion resistant coating, the molds are removed, while the erosion resistant coating remains on the composite impeller.
