Abstract

Improvements in fully demountable spherical sealing valves, intended to be interposed between two elements of the same channel, characterized in that said valves comprise in combination: - a valve body of substantially cylindrical shape that constitutes the support of a spherical obturator of cylindrical, mobile conduit in rotation about the longitudinal axis of said body and in relation to the latter, and provided for this purpose of a pin and of an axial drive shaft to said longitudinal axis having said body a plane of symmetry passing through its longitudinal axis and having a cylindrical transverse hole with longitudinal axis perpendicular to its plane of symmetry and cutting it in the center of the spherical plug, said transverse hole being limited on either side of the plane of symmetry of the body by two annular plane surfaces parallel to said plane of symmetry, two identical tie-straps s coaxial to the longitudinal axis of the transverse hole disposed in the valve body, the common axis coinciding with that of the channel containing the valve, the two said flanges-struts being symmetrical one with respect to the plane of symmetry of the valve body each of them being fixed on said valve body, on the one hand, by adjusting one of its transverse end surfaces at the corresponding entrance of the transverse cylindrical bore of the valve body, the transverse surfaces being in contact of complementary shapes a of the other, a sealing joint interposed between two of the surfaces in contact, and, on the other hand, by removable fastening means of the parts in contact, said flanges-tiers having their transversal surfaces opposed to those by which they go fixed to the valve body coupling means of each of them to one of the channel elements between which the valve is interposed, two identical sealing gasket holders each constituted by a piece of revolution, arranged in normal position, on the one hand, coaxially to each other, their axes of revolution coinciding with the longitudinal axis of the channeling and, on the other hand, symmetrically one of the other in relation to the plane of symmetry of the valve body, each of said seats having a cylindrical conduit whose axis coincides with its axis of revolution and the internal diameter is equal to the time to the inner diameter of the cylindrical conduit of the obturator and to the inner diameter of the conduit; a substantially frustoconical surface whose axis is the axis of revolution of said seat and which is disposed opposite the spherical surface of the shutter and in the immediate vicinity of the latter and is provided with an annular groove or slots for receiving an O-ring sealing that has the axis of revolution by longitudinal axis, whose O-ring is supported on the spherical surface of the obturator following a circle of said spherical surface; a substantially cylindrical external lateral surface disposed in front of the internal lateral surface of a substantially cylindrical housing disposed in the corresponding bracket-strap, whose internal surface is coaxial with the axis of the duct and is provided with an annular groove for receiving an O-ring sealing, whose annular groove has a rectilinear section whose width has a higher value and the depth a value lower than the diameter of a circular meridian section of the O-ring, whose O-ring is supported by its outer equatorial circle at the bottom of the rectangular groove, along which it can move, and is supported by its internal equatorial circle on the lateral surface of said seat with which it cooperates, the respective shapes of the inner side surface of the seat housing and of the external lateral surface of said seat that the distance that separates them is minimal to level of said sealing O-ring; being provided with a surface transverse to the frustoconical surface positioned opposite the spherical surface of the obturator, and cooperating with a compressible elastic member that rests directly or through a rigid part on a stirrup provided on the internal lateral surface of said seat .
