Shutoff valve HF02-02-01Y is an important part of the unit safety system in thermal power plant. It is also an important safety device to ensure the safe operation of the unit and prevent the over-speed accident of the steam turbine caused by the steam backflow in the extraction pipeline.
At present, in order to prevent the over-speed caused by the back-flow of extraction steam, the safety measures adopted by extraction steam units are to install the back-stop valve in the extraction pipeline. However, the back-stop valve used at present has the defects of slow response, imprecise closure, poor reliability and ineffective prevention of the back-flow of extraction steam. It has caused several serious accidents of over-speed caused by the back-flow of extraction steam, and has the major hidden danger of safe production. It is necessary to install a new, safer and more reliable fast shut-off valve in the pipeline to effectively prevent accidents and effectively improve the safety performance of the unit.
