CONTROL VALVE FOR HOT GAS

摘要

FIELD: machine building. ^ SUBSTANCE: valve for control of consumption of hot gas consists of case with inlet and at least one outlet branch. A seat with two lugs is installed in the case. These lugs are located on both sides from delivery outlet of the seat and are made with a common cylinder orifice. A cylinder gate is installed in this orifice. The gate is kinematically tied with the shaft of the drive. Edges are made on both lugs on the most remote from the delivery outlet side. The edges pass along planes perpendicular to axis of the delivery outlet of the seat and through their cylinder orifices; distance between end points along cylinder orifice of the lugs equals to 0.8...0.9 of minimal diametre of the gate contacting lugs of the seat. ^ EFFECT: reduced loading index of valve. ^ 4 dwg
