Abstract

Seat valve with circular rings for fluids, of the type constituted by a valve body inside which are two lateral chambers terminated in their free end areas by flanges or another type of connection in the center of which the valve body has an axial cylindrical passage by means of which the chambers are communicated and said step is topped in a facing widening and in the same way as another end that has the bridge-arcade in which a spindle-stem is connected in axial direction, related to a shutter and driven for a flyer; characterized in that at the end of the fluid inlet chamber and facing the cylindrical passage, the corresponding seat of the valve closure appears, this seat is urinated by means of filler material, with concentric annular ribs and in different planes forming the upper part of said ribs a linear curved-concave contour in which the lower end of the obturator, which has a hemispherical shape, seats; while the steering wheel has centrally a skirt dimensioned to protect the spindle and which allows checking the closing or opening state of the valve, the spindle being related to the obturator through an articulated coupling with the spindle itself; and in that each of the chambers internally has specially shaped ribs that define the corresponding steps for the circulation of the fluid, said circulation being substantially laminar.
