  • Champagne tower-type multi-stage throttle control valve
    Patent number: 11953120
    Abstract: A champagne tower-type multi-stage throttle control valve includes a valve body, a valve cover, a throttle sleeve, and a valve core. A sleeve cavity of the throttle sleeve is shaped as a stepped hole with two or more layers. The valve core is shaped as a stepped shaft with two or more layers coaxial with the throttle sleeve. The number of shaft shoulders of the valve core is smaller than or equal to the number of hole shoulders of the sleeve cavity of the throttle sleeve, such that each set of shaft shoulders of the valve core in an axial direction can form a sealing surface fit with corresponding hole shoulders of the throttle sleeve. A flow channel groove is axially or obliquely formed on each of the hole shoulders of the throttle sleeve and/or the shaft shoulders of the valve core.
