TRIPLE-FUNCTION VENTING VALVE FOR HYDRAULIC INSTALLATIONS

摘要

The inside of the hollow body (1) of the valve incorporates a float (6) associated with an obturator (8), the head (9) of the latter being provided with a "V"-profiled seal (10) capable of fitting hermetically onto the kinetic outlet orifice (2) of the body (1), the obturator (8) having connectors (18) to which are coupled silicone conduits (9) that, at their free end, have spheres (20) forming lever arms sliding via convex tracks (13) made in a cavity (12) of the float (6) on which the actual obturator (8) is inserted, said obturator being connected to said float (6) by means of a rod (15) with a nut (16). In the rest position, the air exits via the kinetic outlet (2), whilst the ascending movement of the float (6) gives rise, first, to closure of said kinetic orifice (2), thereby allowing exit via the silicone conduits (9) and passage or orifice (17) made in the obturator (8), and when the water pushes the float (6) the silicone conduits (9) are throttled, which closes off the exit of water and air to the exterior.
