Description

Es sind bereits Absperrorgane bekannt, bei denen (las Sicherheitsventil, kombiniert mit einem Rückschlagventil und einem Schauglas, in einem einzigen Gußstück untergebracht ist.Shut-off devices are already known in which (read safety valve, combined with a check valve and a sight glass, in a single casting is housed.

Gegenstand vorliegender Erfindung ist ein Absperrorgan, bei dem in einem einzigen Gußstück ein Sicherheitsventil mit im Ablaufstutzen eingebautem Durchflußschauglas, ein Riickschlagventil und ein Filter untergebracht sind.The present invention is a shut-off device in which in a single casting a safety valve with a flow sight glass built into the drain socket, a check valve and a filter are housed.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Absperrorgans dargestellt, und zwar zeigt die Figur einen Längsschnitt.In the drawing is an embodiment of the invention Shown shut-off device, namely the figure shows a longitudinal section.

Das Absperrorgan besteht aus einem Gußstück i mit einer Eintritts- 2- und einer Austrittsöffnung 3, welche voneinander durch eine Wand 4 getrennt sind. Ferner weist das Gußstück i noch einen Ablaufstutzen 5 auf, der seinerseits durch die Wand 6 vom Inneren des Ventilgehäuses abgetrennt ist.The shut-off element consists of a casting i with an inlet 2- and an outlet opening 3, which are separated from one another by a wall 4. Furthermore, the casting i also has a drain connection 5, which in turn goes through the wall 6 is separated from the interior of the valve housing.

In der Trennwand 4 befindet sich ein Ventilsitz 7 für das Rückschlagventil B. Ebenfalls am Ventilsitz 7 ist der Filter angebracht, der das Ventil gegen das Eindringen von Unreinigkeiten schützt. Der Einbau des Rückschlagventils samt Filter geschieht durch Wegnahme des Verschlußzapfens io. ,Zum Reinigen oder Auswechseln des Filters ,kann auch am Gußstück auf der entgegengesetzten Seite ein weiterer Verschlußzapfen angebracht sein. In der Trennwand @6 befindet sich ein weiterer mit Bohrung versehener Ventilsitz @i8 für das Sicherheitsventil. Der die Dichtung i i haltende _Ventilteller 1 2 ist fest mit der vorzugsweise aus Gummi bestehenden Membran 13 verbunden. Letztere ist zwischen Glocke 14 und Gußstück i eingeklemmt. Der Widerstand der Membran 13 kann mittels der verstellbaren, auf die Feder 15 wirkenden, um die Ventilachse angeordneten Mutter 16 reguliert werden.In the partition 4 there is a valve seat 7 for the check valve B. The filter, which protects the valve against the ingress of impurities, is also attached to the valve seat 7. The non-return valve and filter are installed by removing the locking pin io. To clean or replace the filter, another locking pin can also be attached to the casting on the opposite side. In the partition @ 6 there is another valve seat @ i8 with a bore for the safety valve. The valve plate 1 2 holding the seal ii is firmly connected to the membrane 13 , which is preferably made of rubber. The latter is wedged between the bell 14 and the casting i. The resistance of the membrane 13 can be regulated by means of the adjustable nut 16, which acts on the spring 15 and is arranged around the valve axis.

DerAhlaufstutzen 5 ist zur Kontrolle des Flüssigkeitsdurchgangs mit einem bei andern Aggregaten bereits bekannten Schauglas 17 ,ersehen. The drainage nozzle 5 can be seen with a sight glass 17 , which is already known in other units, for checking the passage of liquid.

Die Wirkungsweise des erfindungsgemäßen Al)-sperrorgans ist -die gleiche wie bei den bereits bekannten, die aus mehreren Einzelteilen zusammengesetzt sind.The mode of operation of the Al) blocking element according to the invention is the same as with the already known, which are composed of several individual parts.
