STEAM TURBINE Russian patent published in 2017 - IPC F01D1/12 

FIELD: heat-and-power engineering.

SUBSTANCE: invention relates to heat-and-power engineering, particularly to steam turbines of low power. Proposed steam turbine comprises a housing with a horizontal connector, a fixed on the shaft disc with jet working blades installed in one line perpendicular to the cylindrical surface of the disc and forming rims, two diaphragms, one of which is installed before the jet working blades and comprises guide vanes and sealings to make inlets, and the other diaphragm is installed after the jet working blades and comprises sealings, which form outlets, rotary boxes to vary the working medium motion direction installed over the entire disc circumference above the jet working blades onto the sealings, which form the inlet and the outlet openings, covering the inlet and the outlet openings, a sealings unit arranged between the housing and the shaft and consisting of complete sealings and a device to feed and discharge the working medium. Invention ensures small sizes and low metal consumption of the turbine, as well as actuation of almost the whole enthalpy drop of the working medium (down to 0.03 kg/cm²), promotes reducing power losses, sharp reduction of leaks of the working medium for much higher efficiency of the steam turbine. Turbine has a larger range of RPM, since it is not sensitive to changes in parameters of the steam.

EFFECT: proposed is a steam turbine.
