Further; Turbine casing also is provided with a plurality of second boss and a plurality of the 3rd boss; Each second boss and each the 3rd boss relatively are arranged at the two opposite sides of each first corresponding groove, and the sidewall of each second boss and each the 3rd boss directly connects the two opposite side walls of the first corresponding groove respectively.
Further; Second boss and the 3rd boss that are positioned at each first groove two opposite sides are placed on second groove and the 3rd groove that is positioned at each first boss two opposite sides respectively accordingly; And leave second gap between each second boss and each second groove, leave third space between each the 3rd boss and each the 3rd groove.
The utlity model has following beneficial effect:
1, nozzle ring is located through first groove fit of first boss and turbine casing, thereby realizes circumferential location and the radial location to nozzle ring.
2, simultaneously, second boss of turbine casing setting and the 3rd boss are nested with second groove and the 3rd groove fit of nozzle ring respectively, make that the location is more reliable.
3 and, first gap that exists between nozzle ring and the turbine casing, second gap and third space are that the space has been reserved in the free expansion of nozzle ring.This bar has significantly reduced the spoilage of nozzle ring 1, has prolonged the working life of nozzle ring 1.
4, simultaneously, the nozzle ring position structure of the utility model is simple to operate, safe and reliable.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:

Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1, the nozzle ring position structure of the utility model comprises nozzle ring 1 and turbine casing 2.
The inframarginal 11 of nozzle ring 1 is provided with a plurality of first boss 111.Preferably, the number of first boss 111 can be 8.These 8 first boss 111 are arranged on the inframarginal 11 equably.
Turbine casing 2 is provided with a plurality of first grooves 21.It is corresponding with first boss 111 that first groove 21 is arranged on the position of turbine casing 2.Preferably, the number of first groove 21 can be 8.
When nozzle ring 1 was installed, nozzle ring 1 was fixedly mounted on turbine casing 2 through supramarginal plate (figure does not show).Simultaneously, the inframarginal 11 of nozzle ring 1 is cooperated installation with turbine casing 2, thereby realize location nozzle ring 1.Particularly: first boss 111 of inframarginal 11 is placed in first groove 21 of turbine casing 2 correspondingly, and leaves first gap 25 between first boss 111 and first groove 21.
Preferably, also be provided with a plurality of second grooves 112 and a plurality of the 3rd groove 113 at inframarginal 11.Each second groove 112 and each the 3rd groove 113 relatively are arranged at the two opposite sides of each first corresponding boss 111, and each second groove 112 and the direct respectively two opposite side walls that connects corresponding first boss 111 smoothly of the sidewall of each the 3rd groove 113.
Preferably, also be provided with a plurality of second boss 22 and a plurality of the 3rd boss 23 on the turbine casing 2.Each second boss 22 and each the 3rd boss 23 relatively are arranged at the two opposite sides of each first groove 21, and corresponding with the second corresponding groove 112 of inframarginal 11 and corresponding the 3rd groove 113 respectively.Simultaneously, the sidewall of each second boss 22 and each the 3rd boss 23 all directly and the two opposite side walls of the first corresponding groove 21 be connected.
When nozzle ring 1 was installed, first boss 111 on the inframarginal 11 cooperated one to one with first groove 21 of turbine casing 2 and is nested with.Simultaneously, second boss 22 that is positioned at each first groove, 21 both sides of turbine casing 2 and the 3rd boss 23 cooperate with second groove 112 that is positioned at each first boss, 111 both sides of inframarginal 11 and the 3rd groove 113 accordingly respectively and are nested with.And, between corresponding second boss 22 and second groove 112, leave second gap 27, simultaneously, extend between inframarginal 11 and turbine casing 2 in this second gap 27.Between the 3rd boss 23 of answering mutually and the 3rd groove 113, leave third space 29, simultaneously, this third space 29 also extends between inframarginal 11 and turbine casing 2.
