STERILIZABLE FITTING FOR FLEXIBLE TUBES Russian patent published in 2023 - IPC F16L31/02 

FIELD: fittings for fluid and gaseous media.

SUBSTANCE: fitting with an internal partition redirecting the incoming flow for effective sterilization of the cruciform connection of silicone tubes includes a housing in which two coaxial holes are made, and two structural elements in the form of fittings in which two parallel channels perpendicular to the coaxial holes are made. The internal partition between the channels is not flat, contains a trapezoidal divider for uniform distribution of the incoming flow, preventing its reflection, and is a non-removable fitting element obtained by mechanical processing methods, during which two parallel channels are made in the fitting structural elements in the form of fittings. Two coaxial connecting holes with a flat bottom are made in the fitting body, located perpendicular to the channels in the structural elements in the form of fittings, with a depth from the body plane to the axis of the nearest channel, with the formation of a trapezoidal flow divider located on the axis of the connecting holes in the fitting body.

EFFECT: present invention enables to use the fitting as a connecting cross-shaped element for connecting auxiliary tanks to the main line without loss of tightness and sterility.
