蒸汽节流阀具有（42）围绕所述阀轴线水喷射管道。 水喷射管道（42）位于一个阀笼（30）和一个阀杆引导件（13）的两个邻接的凸缘（40，44）之间。 它们被形成为在凸缘（40）的槽（42），而凸缘（44）的它们的相邻周面是光滑的。 该阀保持架（30）与凸缘（40）形成了一个可更换的磨损部件。 水注入通道的这种设计（42）的热应力裂纹避免在通道中。

The steam throttle valve has the water injection ducts (42) which are disposed around the valve axis. The water injection ducts (42) are located between two abutting flanges (40, 44) of a valve cage (30) and a valve stem guide (13). They are formed as grooves (42) in the flange (40), whereas their adjacent peripheral surface of the flange (44) is smooth. The valve cage (30) with the flange (40) forms a replaceable wear part. This design of the water injection ducts (42) heat stress cracks are avoided in the range of channels.
