AI Technical Summary

Technical Problem

The existing gas turbine nozzle assembly is inconvenient for convenient linkage rotation and adjustment of nozzle direction and convenient linkage flip to close the oil inlet path, which affects the adjustment of fuel injection direction and controllable adjustment of oil inlet path, resulting in poor convenience of use.

Method used

A gas turbine combustion chamber nozzle assembly is designed, including a combustion chamber body and an integrated frame. The push arm and sliding ring are driven by the second electric push rod, and combined with the linkage shaft and the connecting block, the nozzle head is easily rotated; at the same time, the first electric push rod drives the push arm and the movable shaft to move, and the valve plate is used to close the A channel or B channel to realize the controllable adjustment of the oil inlet path.

Benefits of technology

It realizes convenient linkage rotation and adjustment of nozzle direction and convenient linkage flip to close the oil inlet path, which facilitates adjustment of the fuel injection direction and controllable adjustment of the oil inlet path, improving the convenience of use.
