Description

Es sind bereits Rückfluß Verhinderer in Form von Gummischläuchen, Gummilippen und Faltmembranen bekannt, die sich beim Rückfluß um einen Leitkörper schmiegen. Weiterhin sind Rückschlagventile mit einer biegsamen Kappe und einem Schutzrohr bekannt, bei 5 denen das rückströmende Medium das Schutzrohr auffüllt und die biegsame Kappe gegen den Ventilsitz preßt. Weiter sind selbsttätige Ventile bekannt, die zur Dämpfung des Ventilweges mit Faltenbälgen versehen sind. ίοThere are already backflow preventers in the form of rubber hoses, rubber lips and folding membranes known, which nestle around a guide body during reflux. Furthermore, check valves are with a flexible cap and a protective tube known in which the backflowing medium fills the protective tube and the flexible cap against the valve seat presses. Automatic valves are also known which are provided with bellows to dampen the valve travel are. ίο

Diese bekannten Rückflußverhinderer haben den Nachteil, daß sie neben der Erzeugung verhältnismäßig hoher Druckverluste und starker und unerwünschter Druckschläge auch bei Reparaturen oder beim Auswechseln der inneren Teile besondere Fachkenntnisse, oft sogar völlige Demontage und Werkstattarbeit erfordern. Außerdem sind sie gegen Beschädigungen empfindlich.These known backflow preventer have the disadvantage that they are relative in addition to the generation high pressure losses and strong and undesirable pressure surges even during repairs or when changing the internal parts, special expertise, often even complete dismantling and workshop work require. They are also sensitive to damage.

Demgegenüber wird erfindungsgemäß vorgeschlagen, ein Rückschlagventil mit einem in der Richtung der Rohrleitungsachse beweglichen hohlen, an der dem Sitz zugewandten Seite geschlossenen und an der dem Sitz abgewandten Seite offenen, an der offenen Seite festgehaltenen dünnwandigen Verschlußteil aus elastischem Werkstoff dadurch zu verbessern, daß das Verschlußteil ein an der dem Sitz zugewandten Seite verstärkter Faltenbalg ist.In contrast, it is proposed according to the invention, a check valve with one in the direction the pipe axis movable hollow, closed on the side facing the seat and on the the open side facing away from the seat, held on the open side of the thin-walled closure part To improve elastic material in that the closure part is on the side facing the seat reinforced bellows is.

Der Vorteil gegenüber den bekannten Rückschlagventilen liegt darin, daß auf solche Weise der Sitzteil verstärkt werden kann und daß ein rückwärtiges Leitungs- und Halterohr nicht notwendig ist, die gesamte Konstruktion des Rückschlagventils also sehr einfach ist.The advantage over the known check valves is that in such a way the seat part can be reinforced and that a rear line and holding tube is not necessary, the entire Construction of the check valve is very simple.

Aus den Abbildungen ist zu ersehen, daß ein Faltenbalg 3 aus elastischem Werkstoff, der an seinem Sitzteil verstärkt worden ist, beim Rückfluß des Mediums den Ventilsitz absperrt. Der Faltenbalg 3 trägt an der seinem Sitz abgewandten offenen Seite einen Plansch, durch den er mit einem Traggestell 4 verbunden ist. Dieses Traggestell 4 liegt lose in dem Ventilgehäuse 1 und läßt sich durch eine seitliche Montageöffnung 2 ohne besondere Hilfsmittel in das Ventilgehäuse einsetzen oder aus diesem herausnehmen.From the figures it can be seen that a bellows 3 made of elastic material, which has been reinforced on its seat part, when the medium flows back shuts off the valve seat. The bellows 3 has a splash on the open side facing away from its seat, through which it is connected to a support frame 4. This support frame 4 lies loosely in the valve housing 1 and can be inserted into the valve housing through a side mounting opening 2 without special tools or take it out of it.
