Plate drain valve for influencing control pressure of trip valve for steam turbine of power plant, has supply channel and drain channel separated from each other in fluid tight manner after measurement of axial position of plate
Plate drain valve for influencing control pressure of trip valve for steam turbine of power plant, has supply channel and drain channel separated from each other in fluid tight manner after measurement of axial position of plate
The valve has a supply channel (3) for a fluid provided in a plane and discharged into a valve chamber such that another supply channel (2) for another fluid and a drain channel (1) in another plane are discharged in to the valve chamber. The valve chamber is separated from the former plane by a movably supported plate. The latter supply channel and the drain channel are separated from each other in a fluid tight manner after measurement of axial position of a plate (4), where the latter supply channel surrounds the drain channel.
