Abstract

The blocking valve for pipes has screw connected housing parts which enclose a sealing ring whose inner part forms sealing face for a blocking valve plate. The sealing ring is reliably held in a concentric position even under extremely high load loads. The sealing ring (4) is held by axial pins (7) which pass through the sealing ring. The ends of the pins rest against the walls of a dovetail groove formed between the housing halves. Alternatively the ends of the pins project beyond the sealing ring into holding openings. The sealing ring provides a fluid tight joint between the pipe flanges and the periphery of the valve member (10).

Description

Absperrorr1an fur Rohrleitungen Die Erfindung bezieht sich auf ein Absperrorgan fur Rohrleitungen, bestehend aus ;;wei miteinander verschraubbaren Gehäuseteilen mit einem zwischen diesen eingeschlossenen Dichtring, dessen zum Zentrum weisender Innenmantel als Di,chtfldche fUr eine Absperrklappe ausgebildet ist.Shut-off valve for pipelines The invention relates to a Shut-off device for pipelines, consisting of ;; white that can be screwed together Housing parts with a sealing ring enclosed between these, its to the center The facing inner jacket is designed as a diagonal surface for a butterfly valve.

Mit Absperrklappen ausgestattete Absperrorgane bestehen im wesentlichen aus zwei Gehäuseteilen, deren gegeneinander weisende Stirnseiten eine Ringdichtung elufnehmen und einklemmen. Durch die Dichtung sind die diametral zueinander ausgerichteten Achsenden der Absperrklappe geführt. Dabei bildet die nach innen weisende Mantelfläche der Ringdichtung den eigentlichen Dichtsitz, In der Praxis treten nun immer wieder erhebliche Störungen infolge nicht exakt verschlossener DurchgSnge auf, die sowohl durch gealter te als auch aus den Befestigungen gelöste Dichtungen hervorgerufen werden.Shut-off devices equipped with butterfly valves essentially exist consisting of two housing parts, the end faces of which face one another and form a ring seal Pick up and pinch. Due to the seal, the diametrically aligned Axial ends of the butterfly valve out. The inwardly facing lateral surface forms the actual sealing seat of the ring seal, in practice now occur again and again significant disturbances due to not exactly closed passages, which both Caused by old seals as well as seals loosened from the fastenings will.

Ferner treten gelegentlich durch Temperaturbeeinfiussung verformte Ringdichtungen teilweise aus ihren Befestigungsnuten. Dieses fUhrt bei einem nachfolgenden Schließvorgang zu Verquetschungen, die den Austausch der Dichtungen notwendig machen.Furthermore, deformed ones occasionally occur due to the influence of temperature Ring seals partially out of their fastening grooves. This leads to a subsequent one Closing process leads to crushing, which makes it necessary to replace the seals.

Die Erfindung hat sich nun unter Vermeidung der aufgezeigten Nachteile die Aufgabe gestellt, Dichtungen dieser Art selbst unter extremen Belastungen sicher zu zentrieren.The invention has now been achieved while avoiding the disadvantages indicated set the task of securing seals of this type even under extreme loads to center.

Diese Aufhabe wird erfindungsgemäß bei einem Absperrorgan der eingangs genannten Azt dadurch gelöst, daß innerhalb des Dichtringes quer zu dessen Querschnittsachse gerichtete Arretierungsstifte angeordnet sind, deren Länge gegenuber der Breite des unbelasteten Dichtringes verkUrzt ist. Dabei hat es sich in Ausgestaltung der Erfindung als zweckmdßig erwiesen, daß mindestens zwei Arretierungsstifte vorgesehen sind, welche zu den DurchbrUchen der Klappendrehachse um 900 versetzt sind.According to the invention, this task is given in the case of a shut-off device mentioned Azt solved that within the sealing ring transversely to it Cross-sectional axis directional locking pins are arranged, the length of which is opposite to the width of the unloaded sealing ring is shortened. It has been in the design of the Invention proved to be useful that at least two locking pins are provided which are offset by 900 to the openings of the flap axis of rotation.

Ferner wird erfindungsgemäß vorgeschlagen, daß die von beiden Gehäuseteilen gebildete Aufnahmenute schwalbenschwanzförmig ausgebildet ist. Als Variante wird vorgeschlagen, daß die von beiden Gehäuseteilen gebildete Aufnahmenute mit Ausnehmungen zur Aufnahme der Stifte ausgestattet ist.It is also proposed according to the invention that the two housing parts formed receiving groove is dovetail-shaped. As a variant, proposed that the receiving groove formed by the two housing parts with recesses is equipped to accommodate the pins.

Mit einer solchen Ringdichtung werden die eingangs aufgefuhrten Nachteile ausgeschaltet.With such a ring seal, the disadvantages mentioned at the beginning are eliminated switched off.

In der nachfolgenden Beschreibung wird die Erfindung anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigt: Fig. 1 das pbsperrorgan mit Ringdichtung im Ldngsschnitt, Fig. 2 eine Seitenansicht der Dichtung und Fig. 3 eine Variante der Befestigungsmöglichkeit.In the following description, the invention is illustrated by means of FIG the drawings illustrated embodiments explained in more detail. It shows: Fig. 1 the pbsperrorgan with ring seal in longitudinal section, Fig. 2 is a side view of the Seal and FIG. 3 shows a variant of the fastening option.

Das AbsperrDrgon wird im wesentlichen aus zwei mit Flanschen 1 zusommengesetzten Gehbusehölften 2 gebildet. Die gegeneinanderweisenden Flansche 1 bilden gemaß dem in Fig. 1 dargestellten Ausfuhrungsbeispiel eine etwa schwalbenschwanzförmige Nute 3, welche eine Ringdichtung 4 umschließt. Die sich zur Dichtfläche 5 vorzugsweise trapezförmig verjüngende Dichtung 4 ist mit mehreren quer zur Querschnittsachse6gerichteten Arretierungsstiften 7 ausgestattet. Die Stifte können mit dem Ring verklebt oder in anderer Weise verbunden sein. Die Ringdichtung weist zur Durchführung iund Aufnahme von Achsen 8, 9 einer Absperrklappe 10 Bohrungen 11 auf. Bei Montage-der Ringdichtung 4 legen sich die Arretierungsstifte 7 gegen die Innenfläche der Nute 3 und werden von dieser zentriert. Damit verläuft auch die Dichtfläche 5 konzentrisch zur Durchtrittsperipherie des Absperrorgans.The AbsperrDrgon is essentially made up of two flanges 1 added together Walkway half 2 formed. The opposing flanges 1 form according to the The exemplary embodiment shown in FIG. 1 has an approximately dovetail-shaped groove 3, which encloses a ring seal 4. Which is to the sealing surface 5 preferably trapezoidal tapering seal 4 is with several transverse to the cross-sectional axis 6 Locking pins 7 equipped. The pins can be glued or glued to the ring be connected in another way. The ring seal has to carry out i and reception from Axes 8, 9 of a butterfly valve 10 holes 11 on. When assembling the Ring seal 4 place the locking pins 7 against the inner surface of the groove 3 and are centered by this. The sealing surface 5 thus also runs concentrically to the passage periphery of the shut-off device.

Nach dem in Fig. 2 dargestellten Ausführungsbeispiel sind mehrere Arretierungsstifte 7 vorgesehen. Es ist aber auch denkbar, nur zwei Arretierungs stifte einzugliedern, welche zu den DurchbrUchen bzw. Bohrungen um 900 versetzt angeordnet sind.According to the embodiment shown in Fig. 2 are several Locking pins 7 are provided. But it is also conceivable to have only two locking devices to incorporate pins, which are offset by 900 to the breakthroughs or holes are arranged.

Das in Fig. 3 dargestellte Beispiel zeigt eine Variante der Befestigungsmöglichkeit init einer Aufnahmenute 3', welche mit Ausnehmungen 12, die nutenförmig oder als Bohrungen ausgebildet sein können, ausgestattet ist. PatentansprUcheThe example shown in Fig. 3 shows a variant of the attachment option init a receiving groove 3 ', which with recesses 12, the groove-shaped or as Bores can be formed, is equipped.
