Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft eine Neuerung an Rückschlagventilen, besonders für Wasserleitungen, die darin besteht, dafs zum Einführen des Ventils keine besondere Oeffnung an dem Gehäuse angebracht ist; vielmehr erfolgt das Einlegen des Ventilkörpers unmittelbar durch die Ventilsitzöffnung.The present invention relates to an innovation in check valves, especially for water pipes, which consists in the fact that no special opening is made on the housing for inserting the valve; rather it takes place inserting the valve body directly through the valve seat opening.

Der Vortheil, der dadurch erzielt wird, liegt darin, dafs die besondere Oeffnung und damit jeder Schrauben- oder Kapselverschlufs in Wegfall kommt.The advantage which is achieved thereby lies in the fact that the special opening and with it there is no longer any screw or capsule closure.

Das neue Rückschlagventil ist in den Fig. 1 und 2 der beiliegenden Zeichnung im senkrechten Schnitt dargestellt, und zwar zeigtThe new check valve is in Figs. 1 and 2 of the accompanying drawings in the vertical Section shown, namely shows

Fig. ι das Rückschlagventil nach erfolgtem Einführen des Ventils durch die Ventilsitzöffnung in das Gehäuse bei ausgedehntem Gummiring f. Fig. Ι the check valve after the valve has been inserted through the valve seat opening into the housing with an expanded rubber ring f.

Fig. 2 zeigt das Rückschlagventil nach Abflachung 3es Gummiringes f durch Zusammenschrauben der Platten h i. Fig. 2 shows the check valve after flattening 3es rubber ring f by screwing together the plates h i.

Beim Einsetzen des Ventils wird dasselbe mit dem lose zwischen den beiden Scheiben h und i liegenden Ring/" durch die Ventilöffnung eingeführt, bis der Ventilvierkant η in die entsprechende Vertiefung ο eingetreten ist. Mittelst eines über den Führungsflantsch ρ der Scheibe h passenden Schlüssels wird darauf diese obere Scheibe h derart gedreht, dafs die beiden Scheiben sich nähern, so dafs der dazwischen liegende Gummiring f flachgedrückt wird.Upon insertion of the valve is the same h with the loose between the two discs and i lying Ring / "introduced through the valve opening until the valve square η in the corresponding recess ο occurred is. By means of a via Führungsflantsch ρ of the disc h matching key is subsequently this upper disk h rotated in such a way that the two disks approach each other, so that the rubber ring f lying between them is pressed flat.

Claims (1)

Patent-Anspruch:Patent claim: Rückschlagventil für Wasserleitungen zur Einschaltung hinter dem Wasserleitungshahn, dadurch gekennzeichnet, dafs der zwischen zwei gegen einander beweglichen Scheiben eingelegte elastische Ring f, dessen äufserer Durchmesser etwa dem der Ventilöffnung und der Scheiben gleich ist, beim Zusammendrücken durch die Scheiben beträchtlich vergröfsert wird und dann auf den Ventilsitz zu liegen kommt, wodurch eine besondere Oeffnung zum Einführen des Ventils in das Gehäuse überflüssig gemacht wird.Non-return valve for water pipes to be switched on behind the water main faucet, characterized in that the elastic ring f inserted between two mutually movable disks, the outer diameter of which is approximately the same as that of the valve opening and the disks, is considerably enlarged when pressed together by the disks and then on the The valve seat comes to rest, as a result of which a special opening for inserting the valve into the housing is made superfluous.
