Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2,：For the multi-functional spiral case of centrifugal compressor, packet
Top shell 1, shell 3 and lower spiral case 4 are included, the bottom of the top shell 1 is equipped with shell 3, and the shell 3 is in be horizontally set on top shell 1
Bottom margin position, and fit closely and fix with top shell 1, the top of the top shell 1 is equipped with pilot hole 2, the bottom of the shell 3
Portion is equipped with lower spiral case 4 and slot 10, and the lower spiral case 4 is flexibly connected with shell 3 by slot 10, and the side of the lower spiral case 4 is equipped with
Link block 11, the link block 11 are vertical setting in the side wall of lower spiral case 4, and fit closely and fix with lower spiral case 4, described
11 side of link block is equipped with bolt hole 12, and the side of the lower spiral case 4 is equipped with upper volute 8 and bolt 6, and the upper volute 8 is under
Spiral case 4 is fixedly connected by bolt 6, and the side of the upper volute 8 is equipped with conduit 7, and the conduit 7 is through setting in upper volute 8
Side wall, and penetrated through with upper volute 8, the side of the conduit 7 is equipped with positioning plate 14, and the positioning plate 14, which is vertical setting, is leading
The side wall of pipe 7, and be fixed by screws with conduit 7, the side of the positioning plate 14 is equipped with location hole 15.
Further, the side of the top shell 1 is equipped with friction side 9, and the friction side 9 fits closely and fixes with top shell 1,
