CONTROL VALVE FOR A STEAM ENGINE, STEAM ENGINE COMPRISING SAID CONTROL VALVE, AND COMBINED HEAT AND POWER PLANT COMPRISING THE STEAM ENGINE

摘要

The present invention relates to a control valve 50 for controlling and / or regulating a fluid flow, in particular a steam flow, in a steam engine 1, comprising: a valve seat 51, a valve body 52 which is translationally guided along a central axis CA of the control valve 50 and preferably by means of a elastic element 54 is acted upon by force against the valve seat 51, wherein an axial end of the valve body 52 facing the valve seat 51 has a surface 52A beveled towards the central axis of the valve body 52, whereby an annular contact surface with the valve seat 51 is formed, or one facing the valve body 52 axial end of the valve seat 51 has a surface 51A which is beveled towards the central axis of the valve seat 51, whereby an annular contact surface with the valve body 52 is formed. The present invention also relates to a steam engine 1 having the control valve 50 and a combined heat and power plant having the steam engine.
