Elliptical sealing top-loaded rotary valve system
The patent US12038090B2 describes a valve system that includes a valve cartridge composed of a lower and an upper cylinder portion, each featuring open ends, bases, flow openings, and rotor holes. The design incorporates a gasket positioned between the two cylinder portions, facilitating a fluid-tight seal. A rotor, consisting of a stem and a disc, is designed to rotate within the rotor holes. The unique feature of this valve system is the elliptical configuration of the gasket and the disc, which allows the rotor to transition between a closed position—where the disc perimeter aligns with the gasket—and an open position that enables fluid flow between the first and second flow openings.
Additionally, the valve system includes a casing with an internal bore that accommodates the valve cartridge, ensuring that the axes of the inlet, outlet, and flow openings are parallel upon installation. The design also allows for a cover to secure the cartridge within the casing, featuring an access hole aligned with the rotor holes for the stem. The patent further specifies that the major axis of the ellipse is positioned at a 45-degree angle relative to the flow axis, and the rotation of the rotor alters the contact points of the disc perimeter with the gasket. Notably, the lower and upper cylinder portions are identical, enhancing manufacturing efficiency. This innovative valve system aims to improve fluid control in various applications through its unique structural and functional characteristics.
