VALVE OF A STEAM TURBINE

摘要

The valve (1)has a sliding closure element (10) which in the first position (31) closing the first port (4) bears against a surface surrounding same and can then be displaced in a first plane (20) parallel to this surface so that the cross-sectional area of this first port is opened at least in part as the slider moves to the second position (32). A second port (5) can be provided with the slider having two covers (21, 22). The surfaces surrounding the ports can have a seal (70) in respect of the slider.
