Cooling water supply valve for spray-type desuperheater, has flow opening including flow channel, in which throttle pin of throttle body is engaged, where gap of variable length that is permeable for cooling water is formed within channel

摘要

The valve has a regulating valve that regulates the water pressure, where the regulating valve includes a flow opening and an axially movable throttle body cooperating with the flow opening. The opening has a section that is designed as flow channel (3), into which a end-sided, axial throttle pin (4) of the throttle body is engaged, where the inner diameter of the flow channel is larger than the outer diameter of the throttle pin in such a manner that a gap of variable length that is permeable for cooling water is formed within the flow channel.
