Description

Senkrechtspindelventil mit eiförmi,er Gehäuseaußenwand Die Erfindung bezieht sich auf ein ströntungsgünstiges Senkrechtspindelventil, dessen Gehäuse eiförmig ausgebildet ist, so daß es eine Abstützung in den Kanalwinkeln des Ventils bildet und das Ventil gegen mechanische Zug- und Druckbeanspruchungen widerstandsfähig macht.Vertical spindle valve with egg-shaped housing outer wall The invention refers to a flow-favorable vertical spindle valve, its housing is egg-shaped, so that there is a support in the channel angles of the valve forms and the valve is resistant to mechanical tensile and compressive loads power.

Bei einem Ventil dieser Art liegt zwischen dem Austrittskanal und der Gehäusewand ein Hohlraum, der beim Guß des Gehäuses ausgekernt werden muß.In a valve of this type is located between the outlet channel and the housing wall has a cavity that must be cored out when casting the housing.

Die Erfindung besteht nun darin, daß die aus gußtechnischen Gründen erforderlichen Durchbrechungen zu dem unterhalb des über dem Ventilsitz mündenden Kanals in der unteren Wand dieses Kanals angeordnet sind. Besonders zweckmäßig hat es sich dabei erwiesen, diese Kernöffnung als einen in Strömungsrichtung liegenden Längsschlitz auszubilden.The invention consists in the fact that for reasons of casting technology necessary openings to the opening below the above the valve seat Channel are arranged in the lower wall of this channel. Has particularly expedient it turned out that this core opening is located in the direction of flow Form longitudinal slot.

Die Anordnung der Kernöffnung in der Innenwand bringt den großen Vorteil mit sich, daß man mit einem einzigen Kern für das ganze Ventilgehäuse auskommt, der auch den Hohlraum zwischen der durchbrochenen unteren Kanalwandung und der eiförmigen Außenwand ausfüllt und lediglich an der Stelle der unteren Kanalwandung entsprechend eingeschnürt ist.The arrangement of the core opening in the inner wall has the great advantage with the fact that you can get by with a single core for the entire valve housing, which also forms the cavity between the perforated lower duct wall and the egg-shaped one Fills the outer wall and only at the point of the lower duct wall accordingly is constricted.

Auf der Zeichnung ist ,ein Ausführungsbeispiel dargestellt, und zwar zeigt Abb. i einen senkrechten Längsschnitt durch ein solches strömungsgünstiges Eiformventil, Abb. 2 einen Querschnitt gemäß der Schnittlinie A-B der Abb. i.In the drawing, an embodiment is shown, namely Fig. i shows a vertical longitudinal section through such a streamlined one Egg-shaped valve, Fig. 2 shows a cross section according to section line A-B of Fig. I.

Das Gehäuse i des neuen Ventils ist bis auf die Unterbrechung durch den Ventilspindelhals, welcher den Ventilkegel io aufzunehmen hat, vollkommen eiförmig. Lediglich die Spitzen dieser Eiform sind an beiden Enden durch die Anschlußflanschen 8 und 12 abgeschnitten. Der unter dem Ventilsitz 7 mündende Zulaufkanal, welcher durch die Wandungen 2, 3, ¢, 5 und 6 begrenzt ist, führt die Strömung wirbelfrei nach dem Ventilsitz. Oberhalb des Ventilsitzes 7 und der Kanalwandung 5 ist der durch die äußere Eiform entstehende Raum zwischen der eiförmigen Außenwandung und der Kanalwandung 5 nicht durch eine Trennwand von dem strömungsführenden Teil des Ventils abgegrenzt; denn es hat sich erwiesen, daß diese Vergrößerung des Raumes über dem Ventilsitz als Beruhigungsraum und somit nicht störend auf den Strömungsverlauf wirkt.The housing i of the new valve is through except for the interruption the valve spindle neck, which has to receive the valve cone, is completely egg-shaped. Only the tips of this egg shape are through the connecting flanges at both ends 8 and 12 cut off. The inlet channel opening out under the valve seat 7, which is limited by the walls 2, 3, 5 and 6, the flow is eddy-free after the valve seat. Above the valve seat 7 and the channel wall 5 is the The space between the egg-shaped outer wall and the resulting from the outer egg shape of the channel wall 5 not by a partition wall from the flow-guiding part of the Valve delimited; because it has been shown that this enlargement of space above the valve seat as a calming space and therefore not interfering with the flow works.

Der von diesem Raum oberhalb des Ventilsitzes 7 ausgehende Ablaufkanal. 9 wird unten lediglich durch die in Längsrichtung unterbrochenen Leitwandungen i i begrenzt. Es hat sich nun überraschenderweise herausgestellt. daß diese Unterbrechung mit dem darunterliegenden Totwasserraum die günstigen Strömungseigenschaften des Ventils nicht merklich beeinträchtigen.The drainage channel emanating from this space above the valve seat 7. 9 is shown below only by the baffles interrupted in the longitudinal direction i i limited. It has now surprisingly been found. that this interruption with the dead water space underneath, the favorable flow properties of the Not noticeably affect the valve.
