Abstract

A non-return valve built into a pipe line for refrigeration fluid consists of a valve body, compression spring and a spherical stopper element. The valve body is made of two components soldered together. The valve ball and the tapered compression spring are then inserted through the valve outlet port. A radial groove near the inner end of the outlet port locates the larger diameter of the tapered valve spring, so that the ball is pressed against the valve seat, thus closing the valve in the non-return direction.

Rückflußverhinderer für den Einbau in Kältemittel-LeitungenBackflow preventer for installation in refrigerant lines

Die Erfindung bezieht sich auf einen Rückflußverhinderer für den Einbau in Kältemittel-Leitungen mit einem in einem Gehäusehohlraum zwischen achsgleich liegenden Eintritts- und Austrittsstutzen zwischen einem Ventilsitz und einem Hubfänger freifallend angeordneten, vorzugsweise kugelförmigen Ventilschließkörper.The invention relates to a backflow preventer for the Installation in refrigerant lines with one in a housing cavity free-falling between the coaxial inlet and outlet nozzles between a valve seat and a lifting stop, preferably spherical valve closing body.

Bei bekannten Rückflußverhinderern dieser Art ist das Ventilgehäuse aus zwei miteinander verschraubten Nippeln gebildet, von denen der eine den Ventilsitz und. den Eintrittsstutzen: und der andere den Austrittsstutzen aufweist undjden Hubfänger aufnimmt. Hierbei ist die Fertigung verhältnismäßig; kostspielig.In known backflow preventer of this type, the valve housing is formed from two nipples screwed together, one of which is the valve seat and. the inlet nozzle: and the other has the outlet nozzle and receives each lifting stop. The manufacturing process is proportionate; expensive.

Aufgabe der Erfindung ist es, die Fertigung zu verbilligen,.. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Ventilschließkörper mit dem Hubfänger von der Austrltts-The object of the invention is to make production cheaper, .. This object is achieved according to the invention in that the valve closing body with the lift stop from the outlet

seite her in den Austrittsstutzen einführbar und der Hubfänger in eine in den Austrittsstutzen eingestochene Ringnut federnd einrastbar ist. Unter diesen Bedingungen kann das Gehäuse der Arnnatur billig und materialsparend aus miteinander verlöteten Teilen hergestellt werden. Die Montage besteht lediglich darin, daß der Ventilschließkörper und der Hubfänger miteinander von einer Seite her in das Gehäuse eingeschoben werden.side insertable into the outlet nozzle and the lifting catcher can be resiliently latched into an annular groove pierced in the outlet nozzle. Under these conditions, the housing of the Arnnatur can be produced cheaply and in a material-saving manner from parts soldered together. The assembly consists only in that the valve closing body and the lifting stop are pushed together from one side into the housing.

Der Hubfänger muß an seinem vom Ventilsitz abgekehrten Ende radial federnd sein, damit er in die Ringnut des Austrittsstutzens einrasten kann. Bevorzugt ist er in einfacher Weise als kegelig gewickelte Schraubendruckfeder ausgebildet, die mit ihrer großen Endwindung in die Ringnut des Austrittsstutzens einrastbar ist.The lift stop must be radially resilient at its end facing away from the valve seat so that it fits into the annular groove of the outlet connection can snap into place. It is preferably more simple than conical formed wound helical compression spring, which can be locked with its large end turn in the annular groove of the outlet nozzle is.

Die Erfindung wird nachstehend anhand eines in der Zeichnung in einer Achsschnittfigur dargestellten Ausführungsbei— spiels erläutert.The invention is described below with reference to one in the drawing The exemplary embodiment shown in an axial section is explained.

Das Ventilgehäuse besteht im wesentlichen aus einem Nippel 1, der einen Stutzen 2 mit Außengewinde für den Anschluß der Austrittsleitung und einen zur Bildung eines größeren Hohlraumes radial erweiterten Abschnitt 3 hat. Das erweiterte Gehäuseteil 3 weist den Ventilsitz 5 und einen Anschlußstutzen 6 auf.The valve housing essentially consists of a nipple 1, one connector 2 with an external thread for connecting the outlet line and one for forming a larger cavity radially widened section 3 has. The expanded housing part 3 has the valve seat 5 and a connecting piece 6 on.

Der VentüschließkÖrper ist beim Ausführungsbeispiel durch eine Kugel 8, vorzugsweise eine Teflonkugel, gebildet;, die durch den Austrittsstutzen 2 hindurch gegen den Ventilsitz 5 hin zusammen mit einem Hubfänger 9 einschiebbar ist. Der Hubfänger 9 ist beim Ausführungsbeispiel eine kegelig gewickelte Schraubendruckfeder, die mit ihrer großen Endwindung in eine in den Stutzen 2 eingestochene Ringnut 10 einrastet.The valve closing body is in the embodiment by a Ball 8, preferably a Teflon ball, formed; which by the The outlet nozzle 2 can be pushed through against the valve seat 5 together with a lifting catch 9. The lifting catcher 9 is at Embodiment a conically wound helical compression spring, which with its large end turn in a pierced into the nozzle 2 Ring groove 10 engages.
