Abstract
The utility model discloses the Pelton wheel pipeline structure that a kind of lower cross road pipe is removable.There is positive effect: comprise flange alive, Y-pipe, lower cross road pipe, nozzle carrier and groove, wherein, flange of living is threaded connection mode and is connected with lower cross road pipe with Y-pipe respectively, lower cross road pipe is threaded connection mode with nozzle carrier and is connected, and live flange, lower cross road pipe and nozzle carrier are all placed in groove.The utility model structure is simple; all be threaded connection mode between flange alive, Y-pipe, lower cross road pipe, nozzle carrier during use to be connected; dismounting is convenient; flange, lower cross road pipe and nozzle carrier alive are all placed in groove instead of are embedded in inside concrete; the maintenance duration can be shortened; the power generating ratio time, increase the benefit, be applicable to all Pelton wheels.
Description
Technical field the utility model relates to the pipeline structure of Pelton wheel technical field in hydro-electric power generating equipment, especially descends the Pelton wheel pipeline structure that cross road pipe is removable.
Under background technique, cross road pipe is the important component part of horizontal twin nipple Pelton wheel pipeline structure.Domestic existing horizontal twin nipple Pelton wheel adopts the built-in smooth-bore tip structure of base inner mostly, assembling with nozzle the aqueduct line structure be connected mainly adopts upper cross road pipe removable, and lower cross road pipe is cross road tubular construction under integrated type, lower cross road pipe is direct and Y-pipe is welded, be embedded in inside concrete, lower cross road pipe just possesses the effect guiding current.Owing to there is various impurity in current, after long-time running, easily cause line clogging, thus reduce power station generated energy, affect power station economic benefit, if need removal of contamination, so a large amount of associated components such as necessary dismounting nozzle assembling could removal of contamination.Simultaneously because present horizontal twin nipple Pelton wheel mainly adopts the smooth-bore tip of built-in sensors structure to assemble, sensor belongs to the perishable part of rapid wear, need irregular more emat sensor, and prior art structure more emat sensor must pull down the associated components such as nozzle assembling, very inconvenient.Because the workload of dismounting associated components is large, 3 ~ 7 days need be shut down, have a strong impact on the economic benefit in power station.
" a kind of layout of water turbine " (number of patent application: 201210183921.7) disclosed in No. CN102889163A, Chinese patent, comprise the central body of a central rotation, its also containing at least two liquid flow through and the pipeline rotated together with central body, the pipeline respectively viewed from plan view with helical structure stretches out diametrically; Pelton wheel is arranged in the front portion of the stub area of the spirality pipe that each rotates, the impact of the current making water turbine be subject to penetrating in pipeline; Rotated by the runner of Pelton wheel and the mechanical energy of generation is not directly changed into electric energy at rotation assembly, but provide the oil pressure of pipe-line system to complete by the middle hydraulic pressure installation connected.The deficiency of this patent is: the impact transformation efficiency improving spirality pipe, but does not improve the maintenance of whole pipeline and dismounting.
Summary of the invention the purpose of this utility model is exactly the Pelton wheel pipeline structure that a kind of lower cross road pipe will be provided removable, makes it convenient when dismounting is overhauled, the power generating ratio time, increases the benefit.
In order to achieve the above object, the Pelton wheel pipeline structure that the lower cross road pipe that the utility model provides is removable comprises flange alive, Y-pipe, lower cross road pipe, nozzle carrier and groove, and wherein, the main body of Y-pipe is fixed on inside concrete; Flange of living is threaded connection mode and is connected with lower cross road pipe with Y-pipe respectively, and lower cross road pipe is threaded connection mode with nozzle carrier and is connected; Flange, lower cross road pipe and nozzle carrier alive are all placed in groove.When the utility model uses, be all threaded connection mode between flange alive, Y-pipe, lower cross road pipe, nozzle carrier and be connected, dismounting is convenient; Flange, lower cross road pipe and nozzle carrier alive are all placed in groove instead of are embedded in inside concrete, can shorten the maintenance duration, the power generating ratio time.
The Pelton wheel pipeline structure that the lower cross road pipe that the utility model provides is removable has positive effect: comprise flange alive, Y-pipe, lower cross road pipe, nozzle carrier and groove, wherein, flange of living is threaded connection mode and is connected with lower cross road pipe with Y-pipe respectively, lower cross road pipe is threaded connection mode with nozzle carrier and is connected, flange, lower cross road pipe and nozzle carrier alive are all placed in groove, and structure is simple.During use; all be threaded connection mode between flange alive, Y-pipe, lower cross road pipe, nozzle carrier to be connected; dismounting is convenient; flange, lower cross road pipe and nozzle carrier alive are all placed in groove instead of are embedded in inside concrete; the maintenance duration can be shortened; the power generating ratio time, increase the benefit, be applicable to all Pelton wheels.
Accompanying drawing illustrates that the utility model will be further described by reference to the accompanying drawings, please refer to accompanying drawing:
Accompanying drawing 1 represents schematic diagram of the present utility model.
Structure shown in accompanying drawing 1 comprises: nozzle carrier 1, lower cross road pipe 2, live flange 3, Y-pipe 4, groove 5.
The Pelton wheel pipeline structure that the lower cross road pipe that embodiment the utility model provides is removable comprises flange alive, Y-pipe 4, lower cross road pipe 2, nozzle carrier 1 and groove 5, and wherein, the main body of Y-pipe 4 is fixed on inside concrete; Flange of living is threaded connection mode and is connected with lower cross road pipe 2 with Y-pipe 4 respectively, and lower cross road pipe 2 is threaded connection mode with nozzle carrier 1 and is connected; Flange, lower cross road pipe 2 and nozzle carrier 1 alive are all placed in groove 5.When the utility model uses, be all threaded connection mode between flange alive, Y-pipe 4, lower cross road pipe 2, nozzle carrier 1 and be connected, dismounting is convenient; Flange, lower cross road pipe 2 and nozzle carrier 1 alive are all placed in groove 5 instead of are embedded in inside concrete, can shorten the maintenance duration, the power generating ratio time.
The utility model protection domain relates to all changes form recited above.
