Description
Die Erfindung betrifft ein Schrägsitzventil m-it axial - bewegbarem vollwandigem Dichtungskolben.The invention relates to an inclined seat valve with an axially movable element full-walled sealing piston.
Bei diesen Ventilen ist in der Regel in das. Gehäuseein besonderes, meist ringförmiges Gegenglied eingelassen, mit dem der Spindelkolben zusammenwirkt. Der Einbau und die Bearbeitung dieses Gegengliiedes erschweren und verteuern die Fertigung des Ventils. Außerdem bedingt ein solches Gegenglied: einen beträchtlich vergrößerten Gehäusequerschnitt, mithin: eine im Verhältnis! zur Durchflußmenge unnötige, Gewichts- und Abmessungsvergröflerurng des Ventils.With these valves there is usually a special housing in the. mostly annular counter-member let in, with which the spindle piston cooperates. The installation and processing of this counterpart complicate and make the Manufacture of the valve. In addition, such a counterpart requires: a considerable enlarged housing cross-section, therefore: one in proportion! to the flow rate unnecessary increase in weight and size of the valve.
Diese Nachteile sind erfindungsgemäß dadurch behoben, daß die Dichtungszone sowohl teilweise den Kolbenmantel als auch wenigstens teilweise den Kolbenboden umfaßt. Es legt sich der Spindelkolben zur Sperrung des Durchfluss:es, einerseits mit seiner Umfläche an die Wandung des Gehäuses an, anderseits mit seiner Grundfläche in: eine Ausnehmung des Gehäusegrundes. ein. Die Abdichtung erfolgt also erfindungsgemäß nicht in einer senkrecht zur Spind@eiachse gerichteten Ebene; `vie dies bislang üblich ist, sondern nach einer sowohl zur Spindelachse als auch zur Durchflußkanalafihsl schräg verlaufenden Dichtungszone.These disadvantages are eliminated according to the invention in that the sealing zone both partially the piston skirt and at least partially the piston crown includes. The spindle piston lies down to block the flow: it, on the one hand with its surrounding surface on the wall of the housing, on the other hand with its base in: a recess in the bottom of the housing. a. The seal is therefore carried out according to the invention not in a plane perpendicular to the spindle axis; like this so far is common, but according to both the spindle axis and the Durchflußkanalafihsl inclined sealing zone.
Durch die Erfindung ist bei! Schrägs tzve@ntilen auf denkbar einfache Weise eine einwandfreie Ab- sperrung dies Durchflußkanals erreicht. Es ist -weder eine besondere Formgebung des Ventilgehäuses noch dien Einbau von zusätzlichen Dichtungsgliedern, wie Ringen, Stegen ad. d:gl., nötig. Besonders vorteilhaft ist, daß trotzdem nicht nur eine linienförmige, sondern eine flächige; Dichtungszone gegeben ist. Außerdem zeichnet sich das; neue Ventil durch seine-, raun- und gewichtssparende Ausbildung attsi, denn dabei gibt eis keine zur Querschniittssteigerung führende Einbauglieder.The invention is at! Inclined tzve @ ntilen achieves a perfect shut- off of this flow channel in a very simple way. It is -neither a special shape of the valve housing nor the installation of additional sealing members, such as rings, webs ad. d: gl., necessary. It is particularly advantageous that, despite this, not only a linear, but a flat; Sealing zone is given. Also, this stands out; new valve thanks to its, whisper- and weight-saving training attsi, because there are no built-in elements that lead to an increase in cross-section.
In der Zeichnung ist die Erfindung beispielsweise veranschaulicht. Es zeigt Fig. i einen Schnitt durch einen. Auslaufhahn mit unverengbem Durchflüßkanal, Fig. 2 linsen. Schnitt durch einen Auslaufhahn mit verengtem Durch.flußkanal.The invention is illustrated by way of example in the drawing. It shows Fig. I a section through a. Outlet tap with unencumbered flow channel, Fig. 2 lenses. Section through an outlet tap with a narrowed flow channel.
Das Ventil besteht aus dem Gehäuse a mit dem schrägen Hals b, welche die mit Innengewinde versehene Muffe c abschließt, in der die Spindel d verdreh- und verstellbar ist. Diese trägt einen Ventilkolben e, der aus nachgiebigem Werksstoff, z. B. Gummi; besteht oder wenigstens einen Mantel aus solchem Werkstoff besitzt. Der Kolben kann., wie, Fig. 2 zeigt, unten konisch auslaufen.The valve consists of the housing a with the inclined neck b, which closes the internally threaded sleeve c, in which the spindle d can be rotated and adjusted. This carries a valve piston e, which is made of a flexible material such. B. rubber; consists or at least has a jacket made of such a material. As shown in FIG. 2, the piston can taper at the bottom.
Der Kolben e, der als. Sperr- und; Dichtungsglied, wirkt, erfüllt diesen Zweck, indem er sich mixt seiner- Umfläche an die Gehäusednnen;wandlung anlegt und': mit seiner Grundfläche in eine Ausnehmung f des Gehäusegrundes einschiebt. Die Umflächei des Kolbens erfaßt dabei zum Teil: Dieb Wandung des: Halses b, zum Teil diejenige des eigentlichen Gehäuses a.The piston e, which is called. Lock and; Sealing member, acts, fulfilled this purpose by mixing its surrounding surface with the thin casing and ': pushes its base into a recess f in the bottom of the housing. The surrounding area of the piston partially covers: thief wall of: neck b, for Part that of the actual housing a.
Es ergibt sich mithin eine Dichtungs-zone, wie, sie in dein Zeichnung strichpunktiert angedeutet ist. Der Durchflußkanal g kann, in bekannter Weise gemäß Fig. 2 etwas, verengt sein, in weichem Fall die beim Ausführungsbeispiel nach F:i:g. i durch die Ausnehm ing f gebildete scharfe Kante /a nahezu wegfällt. The result is a sealing zone, as it is indicated in your drawing by dash-dotted lines. The flow channel g can, in a known manner according to FIG. 2, be narrowed somewhat, in the soft case that in the exemplary embodiment according to F: i: g. i the sharp edge / a formed by the recess f is almost eliminated.
