ES274161U - New anti-return valve for pressure fluids (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

1.new check valve for pressurized fluids, of the type with no expansion springs, characterized by the fact that the O-ring, supported by its base directly on the base, is placed inside the central chamber of the valve body. Of the valve seat, its rim resting against the cylindrical wall of the chamber, lacking this annular groove wall housing the O-ring and above it and pressing against it, a washer which in turn is held by a ring of pressure forming a gasket fixed against the base and wall of the annular chamber corresponding to the valve seat while the septum of the opposite mouth, for the limitation of displacements of the internal free ball, is made of greater thickness and suitable material, for that the same can act, at the same time, coupling joint of the end of the appropriate conduit to it threaded. 2.new check valve for pressurized fluids according to the previous claim, wherein in the central opening of the transverse septum limiting the displacement of the internal free ball of the central chamber of the valve body, it is replaced by a triangular central opening and three orifices more respectively arranged each in one of the three vertices whereby the ball when displaced against the central opening and pressed against it by the pressure of the pressurized fluid entering the valve body, can not seal each one of the three holes arranged in the respective vertices of the triangular opening in which they are located and thus these holes are not partially or completely blocked, so that the vein of the flow of the fluid coming from the power supply is not constricted, avoiding the formation of negative turbulence. 3.new check valve for pressurized fluids.
