Abstract
The utility model discloses a tail water device of a water turbine, which comprises the water turbine; the tail water device of the water turbine further comprises an inlet flange, an inlet taper pipe, an elbow pipe and an outlet diffusion pipe; the inlet flange is connected with a volute casing of the water turbine, the top end of the inlet taper pipe is connected with the inlet flange, the bottom end of the inlet taper pipe is connected with the elbow pipe, two sides of the elbow pipe are provided with the outlet diffusion pipe. The device has advantages of simple structure, small occupied space and economical manufacture and mounting under necessary working condition, as well as reasonable structure for unblocked tail water; a power vacuum is increased by the diffusion pipe, thereby improving the efficiency of the water turbine.
Description
Technical field
The utility model relates to a kind of water turbine tail water device.
Background technique
Water turbine for cooling tower is in the middle of using process, and the draft tube of water turbine is very big to the effectiveness affects of water turbine, and present case be generally do not have draft tube or cylindrical draft tube is arranged and conical draft tube one of them.
Use cylindrical draft tube lower, cause device efficiency low, in cooling tower water kinetic energy energy saving technical reconstruction, cause unnecessary failure the efficient of energy recovery;
There is requirement in the space of using conical draft tube that water turbine is installed, adopts conical draft tube under a lot of situation that make, and with bringing huge basic retrofit work, thereby is uneconomic, sometimes or even impossible.
The model utility content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of and can overcome above-mentioned defective, energy recovery efficiency is high, and it is little to take up room, water turbine tail water device easy for installation.
The utility model solves the technological scheme that its technical problem adopted: a kind of water turbine tail water device; Comprise water turbine; It is characterized in that: also comprise suction flange, import Taper Pipe, ell and exit cone, suction flange is connected with the spiral case of water turbine, and the top of import Taper Pipe connects suction flange; The bottom connects ell, and the both sides of ell are provided with exit cone.
Described ell is that two bend pipes that are mutually 90 ° are formed by connecting.
The outlet section of described exit cone is a rectangle.
Described import Taper Pipe is the circular cone diffusing tube.The circular cone diffusing tube provides enough pulls of vacuum for the ell of back.
Suction flange guarantees the steadiness of connection; The convenient exit cone that connects of ell that is formed by connecting through the bend pipe that is mutually 90 °; Exit cone has increased power vacuum, has increased pull of vacuum, has so just guaranteed that the tail water device of reduced size can reach bigger suction; Not only improved energy recovery efficiency, and the little simple installation of whole apparatus structure compact volume.
The beneficial effect that the utility model had is: simple in structure, in the operating mode of necessity, it is little to take up room, and makes, installs economical; Rational in infrastructure, tail water is more unobstructed; Increase power vacuum through diffusing tube, improve turbine efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, water turbine; 2, suction flange; 3, import Taper Pipe; 4, ell; 5, exit cone.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; A kind of water turbine tail water device comprises water turbine 1, also comprises suction flange 2, import Taper Pipe 3, ell 4 and exit cone 5; Suction flange 2 is connected with the spiral case of water turbine 1; The top of import Taper Pipe 3 connects suction flange 2, and the bottom connects ell 4, and the both sides of ell 4 are provided with exit cone 5.Ell 4 is that two bend pipes that are mutually 90 ° are formed by connecting.The outlet section of exit cone 5 is a rectangle.Import Taper Pipe 3 is the circular cone diffusing tube.The circular cone diffusing tube provides enough pulls of vacuum for the ell 4 of back.
Suction flange 2 guarantees the steadiness of connection; The ell 4 convenient exit cones 5 that connect that are formed by connecting through the bend pipe that is mutually 90 °; Exit cone 5 has increased power vacuum, has increased pull of vacuum, has so just guaranteed that the tail water device of reduced size can reach bigger suction; Not only improved energy recovery efficiency, and the little simple installation of whole apparatus structure compact volume.
