The one side of plate, the angle a between the upper left listrium and the upper right listrium are less than 180 degree；
The inframarginal includes the lower-left listrium and bottom right listrium in straight panel shape, the lower-left listrium and the bottom right listrium
It is symmetrical set with parallel and across compressor axial line plane, in the one side backwards to the supramarginal plate, the lower-left
Angle between listrium and bottom right listrium is equal to the angle a between the upper left listrium and the upper right listrium.
According at least one embodiment of the application, the upper left listrium and the upper right listrium are integrated component.
According at least one embodiment of the application, the lower-left listrium and bottom right listrium are integrated component.
According at least one embodiment of the application, the blade, the supramarginal plate and the inframarginal are integrated
Component.
At least there are following advantageous effects in the application:
The compressor stator blade of the application, supramarginal plate and inframarginal have in angle or so straight panel, the upper limb of the shape
Plate and inframarginal can reduce the processing duration of stator blade Milling Machining either simplex sequence, improve processing efficiency.

As label indicate same or similar element or element with the same or similar functions.Described embodiment is the application
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
In explanation the application, and it should not be understood as the limitation to the application.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall in the protection scope of this application.Under
Face is described in detail embodiments herein in conjunction with attached drawing.
In the description of the present application, it is to be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown is merely for convenience of description the application and simplifies description, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as protecting the application
The limitation of range.
1 to Fig. 3 the application compressor stator blade is described in further details with reference to the accompanying drawing.
This application discloses a kind of compressor stator blades, may include blade 1 and fixed setting 1 length of blade
The supramarginal plate 2 and inframarginal 3 of direction both ends end.
Wherein, supramarginal plate 2 includes the upper left listrium 21 and upper right listrium 22 in straight panel shape, upper left listrium 21 and the right side
Supramarginal plate 22 is symmetrical set with parallel and across compressor axial line plane；In addition, in the side towards inframarginal 3
Face, the angle a between upper left listrium 21 and upper right listrium 22 are less than 180 degree.
Further, the shape design of inframarginal 3 is identical as supramarginal plate 2.Similarly, inframarginal 3 includes in straight panel shape
Lower-left listrium 31 and bottom right listrium 32, lower-left listrium 31 are left with parallel and plane across compressor axial line with bottom right listrium 32
The right side is symmetrical arranged；In the one side backwards to supramarginal plate 2, the angle between lower-left listrium 31 and bottom right listrium 32 is equal to upper left listrium
Angle a between 21 and upper right listrium 22.
It should be noted that above-mentioned angle a can be fitted according to size, the quantity of stator blade etc. of compressor diameter
The setting of conjunction, it is ensured that stator blade normal mounting use.
The compressor stator blade of the application, supramarginal plate 2 and inframarginal 3 include in angle or so straight panel (i.e. left and right edge
Plate), it is opposite before annular upper and lower listrium, the supramarginal plate 2 and inframarginal 3 of the shape make can guarantee stator blade normally
