Abstract
The utility model relates to a connecting structure between turbine rotary wheel and base ring, including a flange and a base ring connected with a rotary wheel chamber. The flange is evenly provided with a hole, a telescopic joint is arranged to match with the base ring, the telescopic joint is provided with a hole corresponding to the flange hole, a fastening screw is arranged through the flange hole and the telescopic joint hole, and the base ring is connected with a hydraulic pipeline. The utility model is characterized in that the incircle of the flange connected with the rotary wheel chamber is provided with a blocking notch, the inside of the blocking notch is provided with the base ring, the incircle of the interface between the telescopic joint and the flange is provided with a chamfer, a seal ring is arranged between the chamfer and the flange, the incircle surface of the telescopic joint is provided with a circular groove, and the circular groove is provided with a seal ring. The structure provided by the utility model can directly connect the flange and the base ring, effectively increase the contact area between the flange and the base ring connected with the rotary wheel chamber and greatly reduce the phenomenon that the screw for connecting the flange and the telescopic joint is cut due to axial shear stress. In addition, the sealing structure is concentrated on the telescopic joint, thus simplifying the structure.
Description
Technical field
The utility model relates to a kind of turbine chamber and foundation ring linkage structure.
Background technique
Present known turbine chamber and foundation ring link together by slip joint.Its structure is, a flange that links to each other with runner envelope is arranged, the uniform hole that has on the flange, cooperate with foundation ring slip joint is housed, be shaped on the hole corresponding on the slip joint with flange hole, by flange hole and flexible knothole clamping bolt is installed, slip joint is connected with pressure ring by bolt, on pressure ring and foundation ring surface of contact the Stamping Steel Ribbon that prevents that side direction from leaking is installed.Foundation ring in its cooperation is installed in the inside of slip joint, and foundation ring is packed in the concrete, and foundation ring is connected with aqueduct by tie-plate.This structure turbine chamber there is no directly with foundation ring and is connected, foundation ring and slip joint cooperatively interact, connect into as a whole by bolt, its deficiency shows, the weakest place is exactly the bolt that connects turbine chamber and foundation ring in the above-mentioned integral body, when water turbine in when operation, because water flow disturbance, reasons such as mechanical rotation make runner envelope can produce certain vibrations, therefore the very big radial shear stress of generation between turbine chamber and the foundation ring that installs, will cause the weakest Local Force Company connecting bolt to be easy to be cut off like this, make unit operation produce danger thereby cause.
Summary of the invention
The utility model provides turbine chamber and foundation ring linkage structure a kind of simple in structure, reasonable in design for solving the technical problem that exists in the known technology
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of turbine chamber and foundation ring linkage structure, comprise the flange and the foundation ring that link to each other with runner envelope, the uniform hole that has on the flange, cooperate with foundation ring slip joint is housed, be shaped on the hole corresponding on the slip joint with flange hole, by flange hole and flexible knothole clamping bolt is installed, foundation ring is connected with aqueduct by tie-plate, it is characterized in that: the described flange inner periphery that links to each other with runner envelope is shaped on seam, in seam, be fitted with foundation ring, be shaped on chamfering, between chamfering and the flange seal ring is installed at slip joint and flange mating face inner periphery, on the inner peripheral surface of slip joint, have circular groove, seal ring is installed in the circular groove.
The advantage that the utlity model has with good effect is: since with flange that runner envelope links to each other on the uniform hole that has, by the bolton that cooperates with the hole slip joint is arranged, on the flange inner periphery, also have seam, on slip joint and flange mating face, be shaped on and prevent the Stamping Steel Ribbon that leaks, cooperate with slip joint foundation ring is housed, match in the seam of the flange that foundation ring links to each other with runner envelope, foundation ring is connected with aqueduct by tie-plate.Adopt the utility model structure, not only make and directly be connected with the foundation ring formation with the runner envelope flange connecting, but also effectively increased area of contact with runner envelope flange connecting and foundation ring, the phenomenon that the bolt of having avoided flange to be connected with slip joint is cut off owing to be subjected to radial shear stress takes place, in addition, sealing configuration has concentrated on the slip joint, make slip joint play seal action, prevent from simultaneously to break away between runner envelope and the foundation ring, in a word, the utlity model has advantage simple in structure, reasonable in design, that bearing capacity is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of I part among Fig. 1.
Among the figure: 1-runner envelope; 2-flange; 3-bolt; 4-slip joint; 5-nut; 6-Stamping Steel Ribbon; 7-foundation ring; 8-tie-plate; 9-aqueduct; 10-seam; 11-concrete.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, on runner envelope 1, be connected with flange 2, the uniform hole that has on flange 2, have seam 10 on the inner periphery of flange, in seam, be fitted with foundation ring 7, be fitted with slip joint 4 on the foundation ring, have the hole corresponding on the slip joint with flange hole, by flange hole and flexible knothole clamping bolt 3 and nut 5 are installed, the foundation ring 7 that slip joint is cooperated is packed in the concrete 11, on slip joint and flange mating face, be shaped on chamfering, between chamfering and flange, be equipped with and prevent the Stamping Steel Ribbon 6 that leaks, inner peripheral surface at slip joint also is shaped on circular groove, is equipped with equally in the circular groove to prevent the Stamping Steel Ribbon 6 that leaks, and foundation ring 7 is connected with aqueduct 9 by tie-plate 8.
When unit operation, owing to making runner envelope 1, reasons such as water flow disturbance, mechanical shock produce vibrations, runner envelope 1 will drive connected flange 2 and shake together, because foundation ring 7 is packed in the concrete 11, will produce very big shearing stress on the bolt 3 that is connected between flange 2 and the slip joint 4 so again; Because flange 2 has seam 10, foundation ring 7 directly is connected with flange 2 by seam, effectively increased the area of contact of foundation ring 7 and flange 2, so advocating of being produced of runner envelope 1 to just act on the surface of contact with the seam 10 of runner flange connecting and foundation ring 7; So suffered radial shear power reduces greatly between the slip joint that the flange 2 that links to each other with runner envelope links to each other by bolt 3, has so just effectively avoided bolt 3 can not cut off, and makes unit more reliable and more stable in the running.
