Description
Technical field
The utility model relates to Bulb Turbine Units, particularly relates to a kind of Bulb Turbine Units slip joint.
Background technique
Scaled bulb tubular hydraulic generator unit slip joint is used for connecting wheel and turns room and foundation ring, and slip joint is connected with runner envelope filler ring by pressing plate, and press seal circle is in case leak-stopping water.Scaled bulb tubular hydraulic generator in prior art, often to start, shut down, increase the situations such as load, easily cause generator unit vibration, generator unit not only itself vibrates and vibration is reached slip joint, owing to being bolted between slip joint and runner envelope filler ring, slip joint has the radial frictional force be interrupted continuously under unit vibration effect to clamping bolt, cause the continuous wearing and tearing of bolt, when wearing and tearing acquire a certain degree, cause bolt looseness or fracture, after bolt looseness or fracture, the compression of seal ring is disappeared, pressing plate loosens, make there is gap between pressing plate and seal ring and runner envelope filler ring, cause leaking, certain puzzlement is caused to the safe operation of unit, not only increase the maintenance number of times of Bulb Turbine Units, and easily cause whole equipment failure.
Model utility content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of structure simple, safe and reliable and the Bulb Turbine Units slip joint of good sealing effect.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of Bulb Turbine Units slip joint, comprise slip joint sealing clamp, described slip joint sealing clamp comprises fixing part and compressed part, described fixing part is connected with Bulb Turbine Units runner envelope filler ring by fixing bolt, described compressed part and described runner envelope filler ring against, its junction forms vee gutter, seal ring is provided with in described vee gutter, described Bulb Turbine Units slip joint also comprises limit stoper, described limit stoper comprises stop nut and caging bolt, described stop nut is fixedly installed in the outer rim of described fixing part, described caging bolt and stop nut screw-thread fit, and compress with described runner envelope filler ring.
Further improvement as technique scheme:
Pad is provided with between the nut of described caging bolt and stop nut.
Compared with prior art, the utility model has the advantage of:
Bulb Turbine Units slip joint of the present utility model, the outer rim of slip joint sealing clamp fixing part is provided with the limit stoper of stop nut and caging bolt, stop nut is fixedly installed in the outer rim of fixing part, caging bolt and stop nut screw-thread fit, and compress with runner envelope filler ring, rotary stopper bolt, its relative limit nut is moved, and be tightly resisted against on runner envelope filler ring, thus the oscillation space of the vertical direction of restriction slip joint sealing clamp, prevent Relative Vibration between slip joint sealing clamp and runner envelope filler ring, thus reduce the radial pressure of slip joint sealing clamp vibration to fixing bolt, alleviate the wearing and tearing to fixing bolt, fixing bolt is avoided to loosen, and then prevent compressed part and seal ring from producing gap or loosen and cause and leak, the utility model Bulb Turbine Units slip joint not only effectively can solve seepy question, and extend the fastening life-span of fixing bolt.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Bulb Turbine Units slip joint.
Fig. 2 is A-A view in Fig. 1.
In figure, each label represents:
1, slip joint sealing clamp; 11, fixing part; 12, compressed part; 2, runner envelope filler ring; 3, fixing bolt; 4, vee gutter; 41, seal ring; 5, limit stoper; 51, stop nut; 52, caging bolt; 521, nut; 53, pad.
Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Fig. 1 and Fig. 2 shows a kind of embodiment of the utility model Bulb Turbine Units slip joint, this Bulb Turbine Units slip joint, comprise slip joint sealing clamp 1, slip joint sealing clamp 1 comprises fixing part 11 and compressed part 12, fixing part 11 is connected with Bulb Turbine Units runner envelope filler ring 2 by fixing bolt 3, compressed part 12 and runner envelope filler ring 2 against, its junction forms vee gutter 4, seal ring 41 is provided with in vee gutter 4, Bulb Turbine Units slip joint also comprises limit stoper 5, limit stoper 5 comprises stop nut 51 and caging bolt 52, stop nut 51 is fixedly installed in the outer rim of fixing part 11, caging bolt 52 and stop nut 51 screw-thread fit, and compress with runner envelope filler ring 2, by arranging stop nut 51 and caging bolt 52 in the outer rim of fixing part 11, rotary stopper bolt 52, its relative limit nut 51 moves and is tightly resisted against on runner envelope filler ring 2, thus the oscillation space of the vertical direction of restriction slip joint sealing clamp 1, prevent Relative Vibration between slip joint sealing clamp 1 and runner envelope filler ring 2, thus reduction slip joint sealing clamp 1 vibrates the radial pressure to fixing bolt 3, alleviate the wearing and tearing to fixing bolt 3, fixing bolt 3 is avoided to loosen, and then prevent compressed part 12 and seal ring 41 from producing gap or loosen and cause and leak.The present embodiment Bulb Turbine Units slip joint not only effectively can solve seepy question, and extends the fastening life-span of fixing bolt 3.
In the present embodiment, between the nut 521 of caging bolt 52 and stop nut 51, be provided with pad 53, prevent stop nut 51 from loosening.
Although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model.Any those of ordinary skill in the art, when not departing from technical solutions of the utility model scope, the technology contents of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solutions of the utility model, according to the utility model technical spirit to any simple modification made for any of the above embodiments, equivalent variations and modification, all should drop in the scope of technical solutions of the utility model protection.
