Abstract

The stop-cock for 90[deg] pipe connections has a mounting chamber (2) in a one-piece casing (1). The central axes of the chamber are at 45[deg] to the connecting channels (3, 4).

Description

Die Erfindung beinhaltet einen Absperrhahn für Rohrleitungen, welcher eine 90° Auf-Zu-Schaltung aufweist und dessen einteiliges Gehäuse in eine Rohrleitung eingeschweißt wird um Flanschverbindungen, wie bei herkömmlichen Absperrhähnen üblich, zu ersetzen.The Invention includes a stopcock for pipelines, which a 90 ° open-close circuit and whose one-piece housing is welded into a pipeline to flange connections, as usual in conventional stopcocks, too replace.

Hauptvorteil dieser Neuerung ist, Flanschverbindungen bei Rohrleitungen, weiche hauptsächlich umweltgefährdende Medien durchleiten, durch Schweißnähte zu ersetzen.main benefit This innovation is flanged joints in piping, soft mainly environmentally hazardous Pass media through to replace with welds.

Ein weiterer Vorteil ist die Materialeinsparung (Flansche an der Armatur, Gegenflansche, Dichtungen und Verbindungsschrauben). Beide Vorteile sind dem Umweltschutz dienlich. Bei der Erfindung wird das komplette Einbauteil, welches vorher auf Dichtheit geprüft wurde, in den zum Einbauteil passenden Schließraum des eingeschweißten Gehäuses eingebracht bzw. kann wieder entnommen werden.One Another advantage is the material savings (flanges on the valve, Mating flanges, gaskets and connecting bolts). Both advantages are useful for environmental protection. In the invention, the complete Built-in part, which was previously tested for leaks, fitting into the fitting closing chamber of the welded housing introduced or can be removed again.

Die Abdichtung des Schaltzapfens gegenüber der Atmosphäre ist im Einbauteil (5) integriert und besitzt neben der Abdichtung Schaltküken/Dichtbuchse eine Federringunterstützte O-Ringabdichtung und eine von außen nachverstellbare Stopfbuchse.The sealing of the switching pin with respect to the atmosphere is in the built-in part ( 5 ) and in addition to the sealing switch / sealing bush has a spring-ring-supported O-ring seal and an externally adjustable stuffing box.

Die statische Abdichtung des Einbauteils im Schließraum wird durch gekammerte O-Ringe erreicht.The static sealing of the insert in the closing room is chambered by Reached O-rings.

Die hydraulische Abdichtung zwischen den Strömungskanälen erfolgt über ein Schaltküken, welches bedingt durch vorgespannte, außen angebrachte Federringe nachdichtend angeordnet ist. The hydraulic sealing between the flow channels via a Switching chicks which due to preloaded, externally mounted spring washers is arranged sealingly.

Der neue Absperrhahn besteht. aus einem einteiligen Gehäuse (1), einem Schließraum (2), zwei im Gehäuse (1) enthaltene Strömungskanäle (3) (4), zwei im Schließraum (2) angeordnete ringförmige Ausnehmungen (5), welche mit dem Strömungskanal (4) verbunden sind, ein eine Durchtrittsbohrung (10) (11) bestimmendes, drehbar im Einbauteil (6) zwischen den Strömungskanälen (3) (4) angeordnetes Schaltküken (7), welches konisch zum Schaltzapfen (8) verläuft und umgeben ist von einer Dichtbuchse (9), welche dicht schließend in dem Einbauteil (6) integriert und in den Schließraum (2) des Gehäuses (1) eingesetzt wird.The new stopcock exists. from a one-piece housing ( 1 ), a closing room ( 2 ), two in the housing ( 1 ) flow channels ( 3 ) ( 4 ), two in the closing room ( 2 ) arranged annular recesses ( 5 ), which with the flow channel ( 4 ), a through-hole ( 10 ) ( 11 ) determining, rotatable in the mounting part ( 6 ) between the flow channels ( 3 ) ( 4 ) arranged switching chicks ( 7 ), which conically to the switching pin ( 8th ) and is surrounded by a sealing bush ( 9 ), which tightly closing in the built-in part ( 6 ) and into the closing room ( 2 ) of the housing ( 1 ) is used.

Das Schaltküken (7) besitzt radial zwei Durchtrittsbohrungen (10) (11) und axial eine gegenüber dem Schaltzapfen (8) angeordnete Durchflussöffnung (12), welche dem Querschnitt der Durchtrittsbohrungen (10) (11) mindestens gleichkommt.The switching chick ( 7 ) has two radial through holes ( 10 ) ( 11 ) and axially opposite to the switching pin ( 8th ) arranged flow opening ( 12 ), which the cross section of the through holes ( 10 ) ( 11 ) at least equal.

Die Dichtbuchse (9) ist im Einbauteil (6) dichtend eingesetzt und besitzt entsprechend dem Schaltküken (7) Durchflussöffnungen. Die Dichtheit des Schaltkükens (7) im. Durchgang zu den Strömungskanälen (3) (4) wird durch vorgespannte Federringe (13), bedingt durch die konisch verlaufende Dichtfläche des Schaltkükens (7) erzeugt.The sealing bush ( 9 ) is in the built-in part ( 6 ) sealing and has according to the switching chicks ( 7 ) Flow openings. The tightness of the Schaltkükens ( 7 ) in the. Passage to the flow channels ( 3 ) ( 4 ) is made by prestressed spring rings ( 13 ), due to the conical sealing surface of the Schaltkükens ( 7 ) generated.

Die Abdichtung des Schaltzapfens (8) gegenüber der Atmosphäre wird durch eine federringunterstützte O-Ringabdichtung (14) und einer von außen nachstellbaren Stopfbuchspackung (15) gemäß TA-Luft vorgegeben.The sealing of the switching pin ( 8th ) to the atmosphere by a spring-ring-supported O-ring seal ( 14 ) and an externally adjustable stuffing box packing ( 15 ) according to TA-Luft.

Zwischen den Schaltzapfenabdichtungen (14) und (15) kann eine Prüfbohrung angebracht werden.Between the shift plug seals ( 14 ) and ( 15 ) a test hole can be installed.
