TEMPERATURE REGULATOR BUILDING HEATING SYSTEM Russian patent published in 2010 - IPC G05D23/02 F24D3/00 

FIELD: physics; control.

SUBSTANCE: invention relates to devices for controlling and automatic regulation of temperature and is meant for use in temperature regulation systems in buildings with forced circulation water heating. The control element used in the temperature regulator for the building heating system is a cylindrical cup placed in a mixing chamber with possibility of longitudinal displacement with a minimal gap between its outer lateral surface and the inner surface of the mixing chamber which is rigidly attached to the rod of the liquid thermomechanical converter (LTMC). On opposite lateral surfaces of the cup there are through-cuts which lie in such a way that during longitudinal displacement of the cup with complete covering of the opening of the inlet pipe for connecting to the heating system, the opening of the inlet pipe for return water is completely open and vise versa. The liquid thermomechanical converter used is a converter with a rigid body consisting of a cylindrical hollow casing with an end cap inside of which there is a gasket through which passes the rod of the liquid thermomechanical converter with a head in form of a disc. The diametre of the rod is considerably less than the inner diametre of the housing of the liquid thermomechanical converter, which provides the required sensitivity of the liquid thermomechanical converter. Between the end cap of the liquid thermomechanical converter and the heat insulating bushing of a partition there is a spring which presses the bottom of the liquid thermomechanical converter to an adjustment screw fitted in the end wall of the temperature control chamber.

EFFECT: increased efficiency and wider range of controlling the water temperature regulator in a heating system with increased reliability of the regulator and simplification of its design.
