<p>PURPOSE: To provide a steam converting valve capable of providing satisfactory results, particularly in a light load range or when steam temperature near saturation is to be obtained, and enabling control that is accurate in terms of time between a main valve for a main steam flow and an auxiliary valve for an auxiliary steam flow. CONSTITUTION: A steam converting valve VU1 has a main valve V1 for control of a main steam flow f11 and an auxiliary valve V2 for control of an atomizer steam flow f12. The operating forces of a common spindle actuation 1 for the main spindle 5 of the main valve V1 and the auxiliary shaft 50 of the auxiliary valve V2 are transmitted to a main throttle value element 6 or auxiliary throttle valve element 10a via respective first and second spring-elastic couplings FK1, FK2. The spindles 5, 50 are adjusted so that in a closing process, the auxiliary valve V2 closes after the main valve V1 closes, and so that in an opening process, the main valve V1 opens after the auxiliary valve V2 opens.</p> |
