Abstract

A reversing device for double pump units equipped with a reversing valve is proposed in which two arms mounted on the axis of the reversing valve and capable of engaging in recesses in the pressure connection of the pump unit are provided. The recesses in the housing of the pump unit and the sprung arms engaging therein reduce the expense of fitting the valve in as much as they obviate the need for mechanical machining.

Description

La présente invention concerne un dispositif de commutation pour un groupe de pompage constitué par deux pompes centrifuges actionnées indépendamment l'une de 1' autre, comportant un clapet de commutation monté dans la tubulure de refoulement du groupe et obturant l'orifice de sortie de celle des deux pompes qui est arrêtée. The present invention relates to a switching device for a pumping group consisting of two centrifugal pumps actuated independently of one another, comprising a switching valve mounted in the discharge pipe of the group and closing the outlet orifice of that of the two pumps which is stopped.

Les dispositif 8 de commutation de ce type sont très répandus. On peut citer comme exemple celui décrit dans le brevet allemand NO 22 37 io8, dont le dessin montre un clapet de commutation monté sur le côté refoulement du groupe de pompage. Ce clapet peut pivoter sur un axe prévu dans le corps du groupe et s'appliquer ainsi à vo lonté sur l'un ou l'autre des sièges associés aux orifices de sortie respectifs des deux pompes. La pression créée par la pompe qui fonctionne soulève le clapet du siège entourant l'orifice de sortie de cette pompe et l'applique contre le siège associé à l'orifice de sortie de la pompe arrêtée. Lorsque les deux pompes fonctionnent, elles créent des pressions antagonistes qui maintiennent le clapet dans une position médiane. Switching devices 8 of this type are very widespread. An example that can be cited is that described in German patent NO 22 37 108, the drawing of which shows a switching valve mounted on the discharge side of the pumping unit. This valve can pivot on an axis provided in the body of the group and thus apply as desired on one or the other of the seats associated with the respective outlet orifices of the two pumps. The pressure created by the operating pump lifts the seat valve surrounding the outlet of this pump and applies it against the seat associated with the outlet of the stopped pump. When the two pumps are running, they create opposing pressures that keep the valve in a middle position.

Dans les dispositifs connus, la fixation du clapet et le montage de l'axe qui le supporte dans le corps du groupe de pompage nécessitent un usinage de ce corps. In known devices, the fixing of the valve and the mounting of the axis which supports it in the body of the pumping unit require machining of this body.

L'invention a donc pour objet d'éliminer la nécessité d'une telle opération. The object of the invention is therefore to eliminate the need for such an operation.

A cet effet, dans le dispositif selon l'invention, il est prévu deux branches formant ressort qui sont montées sur l'axe du clapet et peuvent s'encliqueter dans des creux formés dans la tubulure de refoulement. For this purpose, in the device according to the invention, there are provided two branches forming a spring which are mounted on the axis of the valve and can snap into recesses formed in the delivery pipe.

Ces creux peuvent être constitués par des zones en retrait du profil de la tubulure, ce qui, dans une pièce moulée, ne nécessite aucune opération d'usinage particuli- re. Le clapet, muni de son axe et de l'étrier qui forme les deux branches de ressort, peut être monté dans la tubulure de refoulement et il suffit ensuite d'engager dans les creux les extrémites libres des (leux brancnes.  These recesses can be formed by areas set back from the profile of the tube, which, in a molded part, does not require any particular machining operation. The valve, provided with its axis and the stirrup which forms the two branches of spring, can be mounted in the delivery pipe and it then suffices to engage in the recesses the free ends of the (two branches).

De toute façon, l'invention sera bien comprise à 1' aide de la description qui suit, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme d'exécution de ce dispositif:
Fig. 1 est une vue en coupe longitudinale dé la tubulure de refoulement d'un groupe de pompage, munie du dispositif de commutation selon l'invention;
Fig. 2 est une vue en coupe transversale de la tubulure de fig. 1, avec une vue de côté du clapet.In any case, the invention will be well understood with the aid of the description which follows, with reference to the appended schematic drawing, representing, by way of nonlimiting example, an embodiment of this device:
Fig. 1 is a view in longitudinal section of the delivery pipe of a pumping unit, provided with the switching device according to the invention;
Fig. 2 is a cross-sectional view of the tubing of FIG. 1, with a side view of the valve.

Dans la tubulure de refoulement 1 d'un groupe de pompage qui n'est représenté que partiellement, un clapet de commutation 2 est monté à pivotement sur un axe 2. Cet axe 2 se prolonge de part et d'autre par deux branches 4, 5, qui font ressort et s'encliquètent par leurs extrémités libres dans des creux 6 venus de moulage avec la tubulure 1.  In the discharge pipe 1 of a pumping unit which is only partially shown, a switching valve 2 is pivotally mounted on an axis 2. This axis 2 is extended on both sides by two branches 4, 5, which spring out and snap into place at their free ends in recesses 6 which have come from molding with the tube 1.
