PUMP-MIXING UNIT OF LOW-TEMPERATURE HEATING SYSTEM Russian patent published in 2024 - IPC F24D3/02 F16L21/00 F16L25/00 

FIELD: heating.

SUBSTANCE: proposed invention is intended for arrangement of heat carrier circulation and distribution modules in collector systems requiring supply of heat carrier with variable temperature. Disclosed is a pump-mixing unit of a low-temperature heating system, comprising two housings, according to the invention, on each housing the branch pipe is double-sided, perpendicular to the pipe axis with an offset from the pipe axis and ends with an internal thread on both sides, wherein both threads of the branch pipe are made equal and equidistant from the axis of the pipe, on each housing closer to the external thread of the pipe, perpendicular to the axis of the pipe, parallel to said two-sided branch pipe, a second double-sided branch pipe is made, at the ends of which there are identical internal threads, which are equidistant from the axis of the pipe; at that, each said flange is made threaded, the thread of which is conjugated with any thread of the first double-sided branch pipe.

EFFECT: creation of a pump-mixing unit consisting of two housings, which allow assembling pump-mixing units, which are variable and easily upgraded, providing combination of heat supply lines and collector group with variety of their mutual arrangement, providing a horizontal position of the circulating pump shaft, regardless of the rotation of the pump around the axis of its connection.
