VALVE FOR REGULATING HOT GAS FLOW Russian patent published in 2024 - IPC F16K5/08 F16K41/04 F16K31/60 

FIELD: mechanical engineering.

SUBSTANCE: invention aimed at creating valves for regulating the flow of hot gas, operating at high pressures and temperatures. The valve for regulating the flow of hot gas contains a housing with inlet and outlet pipes, a cover, a damper made with a lug and rigidly mounted on a shaft mounted on both sides in bearings, the adjacent surfaces of the seat and the damper lug are made in form of cylinders with a common axis coaxial with shaft axis. The novel part in the valve for regulating the flow of hot gas is a drive lever installed on the shaft shank protruding beyond the cover, and a composite gasket consisting of fluoroplastic and metal installed between the drive lever and the cover without a gap, while part of the gasket consisting of fluoroplastic is located closer to the cover.

EFFECT: invention is aimed at increasing the reliability of the valve by eliminating the destruction of its main parts that regulate the flow of hot gas.
