Description

Technical field [0001] The invention relates to the field of industrial technology, in particular to a steam introduction component structure of a steam turbine. Background technique [0002] In the field of thermal power generation, the method used on site is to heat water to generate steam and send the generated steam to the steam turbine. However, the pressure of the steam entering the steam turbine cannot be effectively controlled, which is likely to cause damage to the steam turbine blades. And often need manual adjustment, therefore, need to improve. Summary of the invention [0003] In view of the above-mentioned technical deficiencies, the present invention proposes a steam introduction component structure of a steam turbine. [0004] The present invention is a steam introduction component structure of a steam turbine, which includes a steam control device and a pressure induction cavity arranged in the steam control device, and the steam control device is provided with a s...
