AI Technical Summary

⚠Technical Problem

Existing valve turbines are mostly simple combinations, failing to achieve structural integration, and axial flow blades require high starting flow rates, resulting in higher manufacturing costs.

⚗Method used

A turbine valve with power generation function was designed. It combines an S-type turbine with a butterfly valve and achieves structural integration through pitch control technology. The drag-type blades reduce the starting flow velocity requirement, and the concave surface resistance of the S-type turbine enhances the sealing performance when the valve is closed.

🎯Benefits of technology

It achieves structural integration of valves and turbines, reduces production and maintenance costs, improves valve sealing performance and start-up flow rate requirements, and has stronger structural innovation and technology transferability.

Abstract

The utility model discloses a water turbine valve with power generation function, including pipeline, be equipped with rotating shaft, end plate, control board and vane in the inside of pipeline and be equipped with generator and mobile phone structure in the outside of pipeline, the inner wall of this pipeline is equipped with a plurality of sealed baffle, this rotating shaft is connected with the drive of generator, two end plates are fixedly connected respectively in the both ends of rotating shaft, this control board is connected with vane drive, and a plurality of vane installs between two end plates in the form of variable oar, this mobile phone structure is used for driving control board rotation to switch valve open -close state, when valve opens, outer axle and sealed baffle separate each other, and vane separates each other, when valve closes, outer axle and sealed baffle abut each other to be the state of limiting rotating shaft rotation, and vane abut each other to be sealed connection state, after adopting this scheme, the integration of valve and water turbine can be realized, and the manufacturing cost is reduced.
