Abstract
The utility model provides an auxiliary brake apparatus of a water turbine, comprising a brake mechanism, wherein one end of the brake mechanism is fixed at a water inflow bent pipe of the water turbine, the other end of the brake mechanism is connected with a housing; and the brake mechanism comprises a vertical pipe, a bent pipe and a nozzle sequentially connected with each other, and a ball valve is connected between the vertical pipe and the bent pipe to control the on-off of the water inflow. The brake mechanism is taken as the auxiliary brake apparatus, and the ball valve is used for controlling the water inflow status in the brake mechanism, so that the auxiliary brake apparatus is simple in operation and low in cost.
Description
Technical field
The utility model relates to water turbine assembly field, particularly a kind of complemental brake system that is applicable to impulse turbine.
Background technique
Water turbine is to be the transformation of energy of current the dynamic power machine of rotating mechanical energy.Modern water turbine is installed in the water power plant mostly, is used for driving generator for electricity generation.Water turbine commonly used at present has impulse turbine, reaction turbine, Francis turbine, axial flow hydraulic turbine etc.For impulse turbine; current are before entering the runner zone; earlier form free jet by nozzle, change pressure energy into kinetic energy, free jet impacts the runner rotation with the kinetic energy form; when impulse turbine is shut down braking; usually adopt pressure oil to drive oil brake or its break of pneumatic braking and embrace that brake disc brakes, structure is complicated, and in the braking process; runner influences braking effect because inertia can not stop operating at once.
The model utility content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming of prior art, proposes a kind of complemental brake system that is applicable to impulse turbine
The utility model adopts following technological scheme:
A kind of water turbine complemental brake system, it is characterized in that: comprise that an end is fixed in the hydroturbine water intake bend pipe, the other end is connected to the arrestment mechanism of housing, this arrestment mechanism comprises successively vertical tube, bend pipe and the nozzle that connects, and is connected with ball valve between vertical tube and the bend pipe and is used to realize the controlled water flow break-make.
Further, realize being connected by flange respectively between described ball valve and described vertical tube and the bend pipe.
Further, described nozzle is realized being connected by flange with described bend pipe.
Further, described nozzle is arranged at described housing near tip position.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect: the utility model adopts arrestment mechanism as complemental brake system, comprise vertical tube, bend pipe and nozzle, simple in structure, by streamflow regime in the ball valve control brake mechanism, simple to operate.When water turbine is shut down, close the water turbine nozzle needle, cut off the current of directive runner bucket; when the rotor machine rotating speed is reduced to a certain degree, open ball valve, arrestment mechanism nozzle ejection pressure flow is to bucket; form the resistance opposite, thereby accelerate the rotor machine brake application stoping with the runner sense of rotation.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is for adopting the structural representation of water turbine of the present utility model.
Embodiment
Below the utility model will be further described by embodiment.
With reference to Fig. 1, Fig. 2, a kind of water turbine complemental brake system, comprise that an end is fixed in water turbine 1 water inlet bend pipe 2, the other end is connected to the arrestment mechanism 4 of housing 3, this arrestment mechanism 4 comprises successively vertical tube 5, bend pipe 6 and the nozzle 7 that connects, and is connected with ball valve 8 between vertical tube 5 and the bend pipe 6 and is used to realize the controlled water flow break-make.Realize being connected by flange 9a respectively between ball valve 8 and vertical tube 5 and the bend pipe 6.Nozzle 7 is realized being connected by flange 9b with bend pipe 6.Nozzle 7 is arranged at housing 3 near tip position.
When water turbine is shut down, close the water turbine nozzle needle, cut off the current of directive runner bucket; when the rotor machine rotating speed is reduced to a certain degree, open ball valve 8, arrestment mechanism nozzle 7 ejection pressure flows are to bucket; form the resistance opposite, thereby accelerate the rotor machine brake application stoping with the runner sense of rotation.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
