HIGH TEMPERATURE THROTTLE DEVICE Russian patent published in 2014 - IPC F16K5/04 F16K5/12 F16K49/00 

FIELD: machine building.

SUBSTANCE: high temperature throttle device comprises the housing with an angular location of nozzles for input and output of high temperature gas and throttling member with rotating movable element made as a barrel, with reference to the fixed element with flow outlets in them, mated in an open position of the throttle device, and annular gap between them. The rotating element of the throttling member is rigidly connected to the shaft fixed from axial fixed and packed in the housing. The fixed element of the throttling member is made as a barrel with flow outlets located in opposite locations, installed along an axis of output branch pipe of the housing and forming with opening in the housing a header for heat input of high temperature gas to flow outlets of the barrel. The movable element of the throttling member is made as a barrel placed inside a bush and having flow outlets, made also in opposite places on its cylindrical part. In the housing the cavity of chilling medium limited from the one side with the plug tightly put on the housing through the bottom of which one the packed shaft goes into the inner bore of the barrel, and from the other side - cylindrical sleeve packed along the housing and the shaft is formed. The drain cavity of chilling medium is limited from the one side by the above mentioned cylindrical sleeve, and from another side - by similar cylindrical sleeve installed in series with the first one.

EFFECT: perfected operating performances.
