Abstract

Improved check valve characterized by the fact that it comprises a solid disk acting as a valve body with a relatively small and uniform thickness, which has a circular through hole in its middle, constituting the passage of the valve, standing out in one of the faces of said disc and surrounding the aforementioned orifice, a circular recess in whose upper part an elongated and transverse cavity is configured, being likewise characteristic that the closing element, which has a circular lining and is capable of adjusting in the said recess, has a solid and rigid radial extension to which in turn solidary a transverse cylindrical arm arranged symmetrically, which, to proceed with the assembly of the valve, is introduced simply and precisely into the interior of the elongated cavity, referred to above so that the closing and opening play is produced precisely by turning the arm of the lock inside its housing. It is sufficient to carry out a very simple push-out maneuver to give rise to the detachment of the repeated cover, all under the particular circumstance that the length of the arm is such that when the valve is mounted between two mutually spliced plates, the one that comes face to face with the side of the closing element reach to cover the two ends of it preventing it from leaving the housing under the action of the circulating fluid, which in this way will cause its oscillation exclusively, also emphasizing that the valve body bears on both sides, suitably projecting, corresponding circular sealing gaskets, and that the closing element bears on the contact face with its seat and corresponding thereto, a circular sealing gasket, also being disposed on the upper part of the body, a protruding element to facilitate the removal and placement of the valve at the place of use.
