Abstract
A novel large-flow throttle valve with a valve core assembly improved comprises a valve body. The lower end of the valve body is connected with a metal connector. The valve core assembly is arranged in the metal connector. A flow channel is arranged in the valve core assembly. A valve rod seat is fixedly arranged at the upper end of the valve body. A threaded hole is formed in the valve rod seat. A valve rod with external threads is arranged in the threaded hole in a threaded mode. The valve core assembly comprises an orifice sleeve. The orifice sleeve is divided into an inner ring and an outer ring. The upper ends of the inner ring and the outer ring are connected together, and an air passage is arranged at the connection position. The flow channel is arranged in the inner ring. The outer ring is attached in the metal connector. According to the novel large-flow throttle valve with the valve core assembly improved, the orifice sleeve is ingeniously divided into the inner ring and the outer ring, a one-way sealing ring is arranged between the outer ring and the inner ring and does not contact the inside of the metal connector directly, and therefore requirements on metal connector roughness and size fit tolerance are greatly reduced, and manufacturing difficulty of the metal connector is decreased.
