Specific implementation mode
Below in conjunction with attached drawing, the utility model is described in further detail.
Shown in referring to Fig.1 be used for M701F3 gas turbine turbine stator blades sealing retaining ring structure, including ring body 1 and thoroughly
The low-level seal side 11 of tranquil leaf, ring body 1 is tightly connected by the high-order sealing ring 4 of annular seal plate 2 and turbine stator blade, ring body
1 high-order sealing strip 12 is tightly connected with the low-level seal ring 5 of turbine stator blade, is held down assembly 3 as elastic construction, is passed through compression group
Part 3 adjusts annular seal plate 2 and turbine stator blade, the degree of being completely embedded of ring body 1；Form elastic sealing structure；In high-order sealing strip
12 are equipped with annular sealing strip 122 with the junction of the low-level seal ring 5 of turbine stator blade, and the annular sealing strip 122 passes through screw 6
It is fixed in the groove 123 of ring body 1, forms easy mounted-dismounted type structure；Gas turbine turbine is formed by replacing annular sealing strip 122
The sealing retaining ring structure of stator blade.
In embodiment, the low-level seal side 11 is equipped with the sealing edge 111 rolled over upwards, the sealing edge 111 and gas turbine
The high-order sealing ring 4 of turbine stator blade corresponds to, and the annular seal plate 23 is mounted on sealing edge 111 and a high position is close by holding down assembly
Position between seal ring 4 forms the fitted seal plate between sealing edge 111 and high-order sealing ring 4；The high position sealing strip 12 is equipped with
Rabbet the sealed groove 121 of the low-level seal ring 5 of gas turbine turbine stator blade, the annular sealing strip 122 and low-level seal ring 5
In being adjacent to sealing state.When ring body 1 is worn, i.e., the annular sealing strip 122 of sealed groove 121 wears radiography and rings sealing performance
When, reparation sealing performance can be used as by replacing annular sealing strip 122, ensure the runnability of equipment.It is set on the screw 6
