Description

Dampf umformventil Die Erfindung betrifft ein Ventil zum Umformen von Dampf hoher Temperatur und hohen Druckes in solchen niederer Temperatur und niederen Druckes in Dampfkraftanlagen mit auswechselbar angeordnetem Sitzring und im Bereich des Ventilsitzes quer zur Strömungsrichtung geteiltem Gehäuse und vor und hinter dem Ventilsitz geradlinig verlaufenden und ab dem Ventilsitz in Ausflußrichtung sich kontinuierlich erweiterndem Gehäusedurchflußkanal, wobei zur Geradrichtung des Dampfstromes im vor dem Ventilsitz liegenden Gehäuseteil sternförmig angeordnete Führungsrippen vorgesehen sind, in deren Knotenpunkt eine Führung für die Ventilspindel angeordnet ist.Steam forming valve The invention relates to a valve for forming of steam of high temperature and high pressure in such low temperature and low pressure in steam power plants with a replaceable seat ring and in the area of the valve seat transversely to the flow direction divided housing and in front and running in a straight line behind the valve seat and in the outflow direction from the valve seat continuously widening housing flow channel, with the straight direction of the steam flow arranged in a star shape in the housing part in front of the valve seat Guide ribs are provided, in the node point of which a guide for the valve spindle is provided is arranged.

Zur Vermeidung von Wärmespannungen im Bereich der Sitzpartie ist es erforderlich, das Gehäuse in bekannter Weise zu teilen und den Ventilsitzring auswechselbar anzuordnen. Bei bekannten Ventilen dieser Bauart wird der Ventilsitzring im allgemeinen annähernd allseitig von den beiden Gehäuseteilen umgeben. Infolge der hohen Temperaturen, die auf den Ventilsitz einwirken, ist deshalb bei dieser bekannten Sitzringbefestigung ein radialer Ausgleich der bei Temperaturschwankungen in ihm auftretenden Wärmespannungen nicht möglich und somit ein dichter Abschluß des Ventils nicht gewährleistet.To avoid thermal stress in the area of the seat, it is required to divide the housing in a known manner and to replace the valve seat insert to arrange. In known valves of this type, the valve seat ring is generally Surrounded almost on all sides by the two housing parts. Due to the high temperatures, which act on the valve seat is therefore in this known seat ring fastening a radial compensation of the thermal stresses occurring in it with temperature fluctuations not possible and therefore a tight seal of the valve is not guaranteed.

Die Erfindung hat deshalb das Ziel, zur Vermeidung von Wärmespannungen in dem Ventilsitzteil diesem eine einfache geometrische Form und außen eine genügend große, unmittelbar mit der Atmosphäre in Verbindung stehende Ausstrahlfläche zu geben. Erfindungsgemäß wird dies dadurch erreicht, daß der den Ventilsitz tragende Teil in bekannter Weise ein Gehäusezwischenstück bildet, das als ebene Platte ausgebildet ist und an dessen Stirnseiten Zentrierleisten zur Aufnahme und Zentrierung der Gehäusehälften angeordnet sind.The invention therefore has the aim of avoiding thermal stresses in the valve seat part this a simple geometric shape and outside a sufficient large radiating surface in direct contact with the atmosphere give. According to the invention this is achieved in that the valve seat carrying the Part forms a housing intermediate piece in a known manner, which is designed as a flat plate is and on its end faces centering strips for receiving and centering the housing halves are arranged.

Durch diese neuartige Ausbildung des Sitzringes ergibt sich eine robuste und höchsten Wärmebeanspruchungen gewachsene Konstruktion. Ferner ist ein Verziehen des Sitzringes und deshalb ein Undichtwerden des Ventils praktisch ausgeschlossen. Gleichzeitig wird eine einfache Fertigung des gesamten Ventils und eine leichte Auswechselbarkeit des Sitzringes sowie eine raumsparende schlanke Ausbildung der Gehäuseteile erzielt.This novel design of the seat ring results in a robust one and the highest thermal stresses construction. There is also a warping the seat ring and therefore a leakage of the valve is practically impossible. At the same time, a simple manufacture of the entire valve and an easy Interchangeability of the seat ring and a space-saving slim design of the Housing parts achieved.

In der Zeichnung ist ein erfindungsgemäßes Dampfumformventil im Längsschnitt beispielsweise gezeigt. Der in Pfeilrichtung zuströmende Heißdampf tritt am Eintrittsstutzen 1 in den mit Rippen 2 versehenen Gehäuseunterteil 3 ein, umströmt den Drosselkegel 4, der Sitzflächen 5 und an seinem unteren Ende einen zylindrischen Fortsatz 6 hat, welcher in die am Knotenpunkt der sternförmig ausgebildeten Rippen angeordnete Führung 7 gleitend eingepaßt ist, und durchströmt die aus dem als ebene Platte ausgebildetem Zwischenstück 8 gebildete Drosselstelle 9. Nach Verlassen des mit Sitzflächen 10 und aufgepanzertem Werkstoff 11 versehenen Zwischenstückes 8 gelangt der gedrosselte Dampf in den sich düsenförmig erweiternden Gehäuseoberteil 12, der mit Zugschrauben 13 mit dem Unterteil über das Zwischenstück 8 fest verbunden ist, umströmt gleichzeitig die in Strömungsrichtung angeordnete Ventilspindel 14 und wird am Gehäuseauslaßstutzen 15 umgelenkt, den er am Flansch 16 in Pfeilrichtung verläßt.In the drawing, a steam converting valve according to the invention is shown in longitudinal section, for example. The superheated steam flowing in the direction of the arrow enters the lower housing part 3 provided with ribs 2 at the inlet connection 1, flows around the throttle cone 4, the seat surfaces 5 and at its lower end has a cylindrical extension 6 which enters the guide 7 arranged at the junction of the star-shaped ribs is slidably fitted, and flows through the throttle point 9 formed from the flat plate designed as an intermediate piece 8 Lower part is firmly connected via the intermediate piece 8 , at the same time flows around the valve spindle 14 arranged in the flow direction and is deflected at the housing outlet connection 15 , which it leaves at the flange 16 in the direction of the arrow.
