A valve with filter

Abstract: This valve comprises the ball-type shutoff member (4) and is characterized in that the very shutoff member comprises the filter (7) being incorporated in its inside, said filter being embodied as per a generally cylindrical embodiment and being fitted to the shutoff ball member thus being turned together with this latter. The filter is formed by a cylindrical, tubular socket (8) and a mesh (9) being initially cylindrical and ending in a half dome determining a front opening at whose lower portion an inclined sheet is fixed which has a concave cross-section and an opening being provided at its rear portion. The valve body is provided with a cylindrical, tubular branch (16) housing the filter socket and being capped with a removable cap (17).

Description: This valve with filter is preferably related to those valves being of the so-called ball valve type because the shutoff member is of a generally spherical shape. When incorporating a filter this type of valves must be manufactured with a given particular construction generally determining a bulkier and complex construction for the valve. In order to obtain a valve with filter being of normal dimensions and of a svery simple and less cost-intensive construction, the filter has been incorporated inside the very shutoff ball member, the filter having a generally cylindrical makeup and being fitted to the shutoff ball member in order to thus be turned together with this latter. A valve having these features is known, for example, from the French patent no. 1.462.437. This invention has as its object a valve with filter having as a characterising feature the makeup of the filter, this latter being made up of a cylindrical, tubular socket upperly having fitted to it a mesh being initially cylindrical and ending in a half dome determining a front opening at whose lower portion an inclined sheet is fixed which has a concave cross-section and an opening being provided at its rear portion. Also characteristic of this valve is the fact that its body has a cylindrical, tubular branch housing the filter socket and being capped with a cap which when removed allows to clean the filter. These and other characteristics will be best made apparent by the following detailed description whose understanding will be made easier by the accompanying sheet of drawings showing a practical embodiment cited only by way of an example not limiting the scope of the present invention. In the drawings: Fig. 1 illustrates the valve assembly in a sectional elevation; Fig. 2 shows in a perspective view the longitudinally sectioned valve assembly; and Fig. 3 is a perspective view of the filter being incorporated to the valve. According to the drawings the valve comprises a body 1 with the inlet opening 2 and being fitted at the opposite side with the outlet opening 3. This valve is centrally provided with the shutoff member 4 being embodied as per a generally spherical embodiment and being housed between seats 5 and 6. The filter 7 is incorporated inside this shutoff ball member and is made up of a lower socket 8 being made of plastics material and being embodied as per a cylindrical and tubular embodiment and having upperly fitted to it a mesh 9 being arranged in a transversal arrangement with respect to the flowing direction of the fluid, said mesh being initially cylindrical and upperly forming a half dome determining a front opening 10 at whose lower portion an inclined sheet 11 is fixed which has a concave cross-section and an opening 12 being provided at its rear portion. This filter 7 is fitted to the shutoff ball member 4 by means of fitting into a peripheral recess 13 of the filter (Fig. 3) a protrusion 14 being provided on the shutoff member. With this fitting the filter is turned together with the shutoff ball member. At its lower portion being opposite to the control handle 15 the valve body 1 is provided with a cylindrical, tubular branch 16 housing the filter socket 8 and being capped with a threaded cap 17 with the intermediary of a ring seal 18. The handle 15 being of the radial type (Fig. 1) or of the butterfly type (Fig. 2) is secured to the spindle 19 being fitted to the shutoff ball member 4 by means of a nut 20. The fluid flows in through the opening 2 to thereupon flow through the mesh 9 and out through the opening 3 in a filtered condition. The retained particles fall down through the opening 12 and towards the cavity formed by the socket 8, the sheet 11 and the cap 17, and are then deposited on this latter.

Claims: A valve with filter wherein the shutoff member (4) is of the ball type and comprises the filter (7) being incorporated in its inside, said filter having a generally cylindrical makeup being apt to be fitted to the shutoff ball member (4) to thus be turned together with this latter, the filter (7) and the shutoff ball member (4) being fitted to each other by means of a protrusion (14) of said member being apt to fit into a recess (13) of the periphery of the filter (7); said valve with filter being characterised in that the filter (7) comprises a cylindrical, tubular socket (8) upperly having fitted to it a mesh (9) being initially cylindrical and ending in a half dome determining a front opening (10). A valve with filter as per claim 1, characterised in that the opening (10) of the mesh (9) has its lower portion fixedly fitted with an inclined sheet (11) of concave cross-section, said sheet having an opening (12) at its rear portion. A valve with filter as per claim 1, characterised in that the valve body has a cylindrical, tubular branch (16) housing the socket (8) of the filter (7), said branch being capped with a removable cap (17).
