Abstract
The utility model relates to a double-locating turbine guide blade, comprising a blade crown, a blade body and a blade root. The double-locating turbine guide blade is characterized in that a back radial surface of the blade root is provided with an arc-shaped small groove, while an inner radial surface is provided with a small boss which can be fitly embedded in the arc-shaped small groove; the back radial surface of the blade crown is provided with an arc-shaped large groove while the inner radial surface is provided with a large boss which can be fitly embedded in the arc-shaped large groove. Witht the arrangement of the bosses and grooves, which can be buckled with each other on the blade crown and the blade root, the radiations of the blade are ensured to be stabilized in the same level when the blade is being assembled, so that the assembling precision and quality are improved.
Description
Technical field
The utility model relates to a kind of steam turbine guide vane, particularly a kind of pair of location steam turbine guide vane.
Background technique
Turbine blade be in the steam turbine in order to guiding fluid to flow by certain orientation, and the vitals of drive rotor rotation.Need to be looped around ringwise some blades on the rotor during assembling, traditional turbine blade is when assembling, because it does not have position structure, can't guarantee assembly precision, the moving vane radial ray usually occurs not in conplane phenomenon, cause radial ray dislocation, fluctuation of service, thus affect the generating efficiency of steam turbine.
Summary of the invention
The technical problems to be solved in the utility model provides the high two location steam turbine guide vane of a kind of installation precision.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pair of location steam turbine guide vane, comprise integral shroud, blade and blade root, its innovative point is: the back of the body sagittal plane of described blade root is provided with the little groove of circular arc, and interior sagittal plane is established the small embossment that just can embed the little groove of circular arc; The back of the body sagittal plane of described integral shroud is provided with the circular arc big groove, and interior sagittal plane is established the large projection that just can embed the circular arc big groove.
The utility model has the advantage of: by integral shroud and blade root boss and the groove that can fasten being set, so that guarantee that its radial ray is stabilized in same plane during blade assembling, improve assembly precision and quality.
Description of drawings
Fig. 1 is the two location of the utility model steam turbine guide vane structural representations.
Embodiment
As shown in Figure 1, comprise integral shroud 1, blade 2 and blade root 3, be provided with the little groove 41 of circular arc at the back of the body sagittal plane of blade root 3, interior sagittal plane is established the small embossment 42 that just can embed the little groove 41 of circular arc; The back of the body sagittal plane of integral shroud 1 is provided with circular arc big groove 51, and interior sagittal plane is established just can embed large protruding 52 of circular arc big groove 51.
