Description

Bei Schiebergehäusen mit eingeschweißten Anschlußstutzen, deren Stirnenden die Sitzflächen tragen, verursacht das Einschweißen, daß die Sitzflächen sich erwärmen und verziehen, und. nach dem Schweißen vielfach nachbearbeitet werden müssen, was wegen der notwendigen Genauigkeit der Bearbeitung nicht einfach ist.In the case of valve bodies with welded-in connection pieces, the front ends of which are the seat surfaces wear, the welding causes that the seat surfaces heat up and warp, and. after the welding often have to be reworked, which is because of the necessary accuracy editing is not easy.

Die Erfindung behebt diese Schwierigkeit dadurch, daß die Wärme abgeführt wird, und zwar indem innen und! außen, in den Rohrstutzen Εϊω-stiche vorgesehen werden. Derartige Einstiche in den Rohrstutzen von Schiebergehäuseo sind- an sich bekannt, und zwar auch zur Abfuhr von Wärme, nämlich der Wärme von· den Schweißstellen her, mit denen das Gehäuse mit der Rohrleitung verbunden wird. Die bekannten Einstiche oder Rillen sind außerhalb des Gehäuses angeordnet. Die Anordnung von Einstichen auf der inneren und äußeren 'Mantelfläche der Rohrstutzen' innerhalb des Gehäuses bringt es mit sich, daß die Spannungen in der Rohrleitung noch besser aufgenommen werden. Die bekannten Einstiche außerhalb des Gehäuses sind nicht dazu gedacht, die Elastizität der Rohrstutzen zu verbessern, vor allem aber halten sie die Kräfte in der Rohrleitung nicht von den Sitzflächen, fern. Die erfindungsgemäßen Einstiche 4 und S innerhalb des Gehäuses, wie sie in der Zeichnung dargestellt sind, bewirken, daß die Längskräfte in den Rohrleitungen durch dieThe invention overcomes this difficulty in that the heat is dissipated, namely by inside and! outside, in the pipe socket Εϊω-stitches are provided. Such punctures in the pipe socket of the valve housing are on known, namely also for the dissipation of heat, namely the heat from the weld points with which the housing is connected to the pipeline. The well-known punctures or grooves are arranged outside the housing. The arrangement of punctures on the inner and outer 'jacket surface of the pipe socket' within the housing brings with it that the stresses can be absorbed even better in the pipeline. The well-known punctures outside of the housing are not intended to improve the elasticity of the pipe socket, but above all do not keep the forces in the pipeline away from the seat surfaces. The punctures according to the invention 4 and S within the housing, as shown in the drawing, cause the Longitudinal forces in the pipelines through the

Stutzen 2 in erster Linie von einem steifen Gehäuse 3 aufgenommen und nur so weit auf die Dichtflächen übertragen werden, wie es der Elastizität der Rohrstutzen mit ihren Einstichen im Verhältnis zu der Steifigkeit des Gehäuses entspricht. Die Zahl und Tiefe der Einstiche und ihre Lage richtet sich nach den jeweiligen Verhältnissen. Es können ein·, zwei oder mehrere Einstiche vorgesehen werden. Um' Kerbwirkung zu vermeiden·, sind die Einstiche zweckmäßig abgerundet.Nozzle 2 primarily from a rigid housing 3 and only transferred to the sealing surfaces as far as the elasticity the pipe socket with its grooves corresponds to the rigidity of the housing. The number and depth of the grooves and their location depends on the respective conditions. It one, two or more punctures can be provided. In order to avoid 'notch effects · are the Punctures rounded off.
