Abstract

A filter for installation in a tap access pipe, preferably for use in tanks for preventing the passage of foreign bodies and regulating the incoming fluid flow, reducing the volume of fluid per unit time. The tap comprises a thin rectangular body, with two distinct sections: a first section (1) having, on both faces, a plurality of oblique fins (3), the fins of one face being offset with respect to the fins of the other face, and the fins of each face being arranged alternately in an opposite manner, together forming a labyrinthine passage for reducing the speed of the fluid flowing through said first path section (1). The other section (2), which follows the first, has semi-circular fins (8) on both faces, the fins of one face being opposite the fins of the other face and being arranged perpendicularly to the plane and longitudinal axis of the rectangular body. Said semi-circular fins (8) have notches (9) on the edge thereof, creating small passages for the fluid flowing from the first section (1). These notches (9) constitute the filter means for preventing the passage of small foreign bodies.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

Como se puede ver en las figuras referidas, el filtro de la invención presenta una configuración general cilindrica para su disposición axial y concéntrica en el conducto de entrada de fluido al correspondiente grifo en el que se aplique.As can be seen in the aforementioned figures, the filter of the invention has a general cylindrical configuration for its axial and concentric arrangement in the fluid inlet conduit to the corresponding tap in which it is applied.

En dicha configuración general cilindrica están establecidos dos tramos contiguos 1 y 2, determinados a partir de sendas partes rectangulares y planas, ligeramente desfasadas entre si como se deja ver en la figura 5.In said general cylindrical configuration two contiguous sections 1 and 2 are established, determined from both rectangular and flat parts, slightly offset from each other as shown in Figure 5.

Sobre ambas caras del tramo plano 1 se han previsto una pluralidad de aletas 3 perpendiculares a tales caras, desfasadas entre si las de una cara respecto a las de la otra, y en disposición oblicua, presentando las aletas 3 la forma de un triángulo rectángulo, uno de cuyos lados o catetos 4, que es el de mayor longitud, es el adosado al plano o cara del tramo 1, mientras que el otro lado o cateto 5 queda perpendicular a la cara y distanciado del borde correspondiente al tramo plano y rectangular 1 propiamente dicho. Esas aletas 3 de cada cara están posicionadas alternativamente de forma contraria, siendo el lado 6 correspondiente a la hipotenusa de cada aleta 3 de perfil curvo, con un resalte 7 en su punto más elevado.On both sides of the flat section 1 a plurality of fins 3 perpendicular to such faces are provided, offset from each other on one side with respect to the other, and in oblique arrangement, the fins 3 presenting the shape of a right triangle, one of whose sides or legs 4, which is the longest, is attached to the plane or face of section 1, while the other side or leg 5 is perpendicular to the face and distanced from the edge corresponding to the flat and rectangular section 1 itself. These fins 3 of each face are alternately positioned opposite, the side 6 corresponding to the hypotenuse of each fin 3 of curved profile, with a protrusion 7 at its highest point.

Las aletas 3, según la forma y disposición de las mismas, determinan un tramo laberíntico que hace que el caudal de fluido circulante pierda velocidad. Es decir, dicho tramo 1, como tramo anterior al sentido de circulación del fluido, actúa como medio reductor de la velocidad. Por su parte, el tramo 2 presenta una pluralidad de aletas semicirculares 8, perpendiculares y en oposición las de una cara respecto de las de la otra, determinando tabiques discoidales y transversales, estando dichos tabiques afectados de almenas 9 de diferente amplitud o profundidad para determinar conjuntamente que dicho tramo 2 actúe como medio de filtrado del flujo, a continuación del tramo 1 reductor de la velocidad.The fins 3, according to their shape and arrangement, determine a labyrinthine section that causes the flow of circulating fluid to lose speed. That is, said section 1, as a section before the direction of fluid circulation, acts as a speed reducing means. On the other hand, section 2 has a plurality of semicircular fins 8, perpendicular and in opposition to those of one face with respect to those of the other, determining discoid and transverse partitions, said partitions being affected by battlements 9 of different amplitude or depth to determine together that said section 2 acts as a means of filtering the flow, following the speed reducing section 1.

El filtro asi constituido se posiciona correctamente de forma axial y centrada en el correspondiente conducto de entra del fluido al respectivo grifo en el que se aplique, al contar los bordes laterales del tramo 1 con unos salientes 10 que contactan con la superficie interna de dicho conducto, en combinación con los resaltes 7 de las aletas 3. Finalmente, decir que el extremo libre correspondiente al tramo 1 presenta una prolongación central y axial 11 determinante de un medio de agarre para la extracción del filtro respecto del conducto en el que se posicione, permitiendo con ello llevar a cabo la limpieza correspondiente. The filter thus constituted is correctly positioned axially and centered on the corresponding fluid inlet conduit to the respective tap in which it is applied, by counting the lateral edges of section 1 with projections 10 that contact the internal surface of said conduit , in combination with the projections 7 of the fins 3. Finally, to say that the free end corresponding to the section 1 has a central and axial extension 11 determining a gripping means for the extraction of the filter with respect to the conduit in which it is positioned, thereby allowing the corresponding cleaning to be carried out.
