Analysis of modern designs combined stop-control valves of steam turbines
Keywords:
control valve, steam distribution, steam turbineAbstract
The article presents an analysis of modern designs combined stop-control valves for power steam turbines. Comparative analysis allowed us to determine the main advantages and disadvantages of the design developed turbine-building companies of Power Machines, ENTEK, Turboatom, ABB, Alstom. In conclusion, it noted that the use of combined designs of stop-control valve is a promising direction in both the design of new turbines, and operated under the modernization. The analyzed designs of valves have high levels of efficiency and reliability. However, analysis of the experience of their operation indicates the presence of a number of problems, the solution of which will give further opportunity to fully realize their potential.
